BOTOX® Demonstrates Efficacy in Reducing Urinary Leakage Episodes
IRVINE, CA, USA I January 18, 2013 I Allergan, Inc. (NYSE:AGN) announced today that the U.S. Food and Drug Administration (FDA) has approved BOTOX® (onabotulinumtoxinA) for the treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency and frequency in adults who have had an inadequate response to or are intolerant of an anticholinergic medication. In two double-blind, randomized, multi-center, placebo-controlled 24-week clinical trials among adults with overactive bladder who had not been adequately managed with anticholinergic treatments, BOTOX® reduced daily urinary incontinence (leakage) episodes as compared to placebo by 50 percent or more by week 12 (reduction of 2.5 episodes from baseline of 5.5 episodes in one study and reduction of 3 episodes from baseline of 5.5 episodes in the second study for those treated with BOTOX® vs. a reduction of 0.9 episodes from a baseline of 5.1 episodes in one study and a reduction of 1.1 episodes from a baseline of 5.7 episodes in the second study for those treated with placebo).1
"Allergan has a long-standing commitment to study the potential of BOTOX® to treat a number of different medical conditions," said Scott Whitcup, M.D., Allergan’s Executive Vice President, Research and Development, Chief Scientific Officer. "With today’s approval, BOTOX® is now approved for 26 different indications in more than 85 countries. Most importantly, today’s FDA approval is a milestone in the treatment of this burdensome condition and will provide a novel option for urologists and their OAB patients."
While the exact cause is often unknown, OAB is a medical condition that results in an uncontrolled urge to urinate, frequent urination and, in many patients, uncontrollable leakage of urine. In the United States, an estimated 14.7 million adults experience symptoms of OAB with urinary incontinence (unexpected leakage of urine).2 Anticholinergics, which are often prescribed as pills, are used by approximately 3.3 million Americans with OAB, with or without urinary incontinence, to manage their condition.3 It is estimated, however, that greater than 50 percent of these patients stop taking at least one oral medication within 12 months, likely due to an inadequate response to, or intolerance of, the medication.4
"Overactive bladder can be a difficult condition to treat as there have been limited options for patients when currently available medications have failed to provide them with adequate relief," said Dr. Victor Nitti*, Vice Chairman, Department of Urology and Director of Female Pelvic Medicine and Reconstructive Surgery at NYU Langone Medical Center. "With the approval of BOTOX®, we have a new treatment option to offer these patients that has demonstrated efficacy in reducing urinary leakage and other symptoms of OAB with the effect lasting up to six months."
The median duration for efficacy with BOTOX® at reducing urinary leakage and other symptoms of OAB in the two clinical studies was 135-168 days compared to 88-92 days with placebo based on qualification for retreatment. To qualify for retreatment, at least 12 weeks must have passed since the prior treatment, post-void residual urine volume must have been less than 200 mL and patients must have reported at least two urinary incontinence episodes over three days. BOTOX® treatment relieves OAB symptoms by temporarily calming muscle contractions by blocking the transmission of nerve impulses to the bladder muscle.
OAB Clinical Development Program
The FDA approval of BOTOX® was based on safety and efficacy data from two double-blind, randomized, multi-center, placebo-controlled 24-week clinical studies of 1,105 adult patients whose OAB symptoms had not been adequately managed with anticholinergic therapy, either due to lack of efficacy or intolerance of the medication. To qualify for the study, patients had to have symptoms of OAB with symptoms of urge urinary incontinence, urgency and frequency, and experience a minimum of three urinary urgency leakage (incontinence) episodes and at least 24 urination episodes (micturitions) over a three-day timeframe. Patients in the studies were randomized to receive physician-administered treatment with 100 units of BOTOX® neurotoxin (n=557) or placebo (n=548) injected directly into the detrusor (bladder) muscle. Patients were treated in the physician’s office and received a local anesthetic, with or without sedation, to numb the bladder prior to treatment with BOTOX® or placebo.
In both clinical trials, patients treated with BOTOX® experienced a reduction of 50% or more in the frequency of daily urinary incontinence episodes from baseline compared to placebo at week 12 (reduction of 2.5 episodes from baseline of 5.5 episodes in one study and reduction of 3 episodes from baseline of 5.5 episodes in the second study for those treated with BOTOX® vs. a reduction of 0.9 episodes from a baseline of 5.1 episodes in one study and a reduction of 1.1 episodes from a baseline of 5.7 episodes in the second study for those treated with placebo).1 In addition, approximately three times as many patients treated with BOTOX® in the clinical studies achieved a complete elimination of their leakage episodes as compared to placebo (22.9% and 31.4% achieved complete continence with BOTOX® vs. 6.5% and 10.3% with placebo at week 12 in the two clinical trials).5 Improvements in other symptoms of overactive bladder, including urge to urinate, frequency of urination and the amount of urine voided also occurred with BOTOX® treatment compared to placebo at week 12.
In the clinical studies, the most frequently reported adverse reactions within 12 weeks of receiving BOTOX® injections included urinary tract infection (18% vs. 6% with placebo), dysuria (9% vs. 7% with placebo), which means painful or difficult urination; and urinary retention (6.5% vs. 0.4% with placebo), which is a temporary inability to fully empty the bladder requiring the use of a disposable self-catheter.
About BOTOX® (onabotulinumtoxinA)
BOTOX® is a prescription-only medical product that contains tiny amounts of a highly purified botulinum toxin protein refined from the bacterium, Clostridium botulinum. The BOTOX® formula contains auxiliary proteins that stabilize the core toxin in BOTOX® from degradation. When injected at doses approved by the FDA into a specific muscle or gland, BOTOX® neurotoxin is expected to act locally to produce a safe and effective result, usually lasting between three to ten months depending on the approved indication and on the individual patient.
BOTOX® was first approved by the FDA more than 22 years ago for the treatment of strabismus and blepharospasm, two eye muscle disorders, making it the first botulinum toxin type A product approved in the world. Today, BOTOX® neurotoxin is approved to treat a total of eight medical conditions in the United States, including the abnormal head position and neck pain that happens with cervical dystonia (CD) in adults; symptoms of severe underarm sweating (severe primary axillary hyperhidrosis) when medicines used on the skin (topical) do not work well enough; for the treatment of increased muscle stiffness in elbow, wrist, and finger muscles in adult patients with upper limb spasticity; for the prophylactic treatment of headaches in adults with Chronic Migraine, a distinct and severe neurological disorder characterized by patients who have a history of migraine and suffer from headaches on 15 or more days per month with headaches lasting four hours a day or longer; for the treatment of urinary incontinence due to detrusor overactivity associated with a neurologic condition (e.g. spinal cord injury [SCI], multiple sclerosis [MS]) in adults who have an inadequate response to or are intolerant of an anticholinergic medication; and for the treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency and frequency in adults who have had an inadequate response to or are intolerant of an anticholinergic medication.
In addition to its therapeutic uses, the same formulation of BOTOX® with dosing specific to moderate to severe glabellar lines was approved by the FDA in 2002 under the trade name BOTOX® Cosmetic (onabotulinumtoxinA). BOTOX® Cosmetic is indicated for the temporary improvement in the appearance of moderate to severe glabellar lines (frown lines between the eyebrows) associated with corrugators and/or procerus muscle activity in adult patients up to 65 years of age.
Since its first approval in 1989, BOTOX® has been recognized by regulatory authorities worldwide as an effective treatment for 26 different indications in approximately 85 countries, benefiting millions of patients worldwide.
In addition to the more than 22 years of clinical experience, the safety and efficacy of BOTOX® have been well-established in approximately 65 randomized, placebo-controlled clinical trials and in approximately 15,000 patients treated with BOTOX® and BOTOX® Cosmetic in Allergan’s clinical trials.6 Worldwide, approximately 35 million vials of BOTOX® and BOTOX® Cosmetic have been distributed over the past 21 years (1990-2011).7
With approximately 2,500 articles on BOTOX® and BOTOX® Cosmetic in scientific and medical journals,8 BOTOX® neurotoxin is one of the most widely researched medicines in the world.
BOTOX® (onabotulinumtoxinA) & BOTOX® Cosmetic (onabotulinumtoxinA) Important Information
Indications
BOTOX® is a prescription medicine that is injected into muscles and used:
to treat overactive bladder symptoms such as a strong need to urinate with leaking or wetting accidents (urge urinary incontinence), a strong need to urinate right away (urgency), and urinating often (frequency) in adults 18 years and older when another type of medicine (anticholinergic) does not work well enough or cannot be taken.
to treat leakage of urine (incontinence) in adults 18 years and older with overactive bladder due to neurologic disease who still have leakage or cannot tolerate the side effects after trying an anticholinergic medication
to prevent headaches in adults with chronic migraine who have 15 or more days each month with headache lasting 4 or more hours each day in people 18 years or older
to treat increased muscle stiffness in elbow, wrist, and finger muscles in people 18 years and older with upper limb spasticity
to treat the abnormal head position and neck pain that happens with cervical dystonia (CD) in people 16 years and older
to treat certain types of eye muscle problems (strabismus) or abnormal spasm of the eyelids (blepharospasm) in people 12 years and older
BOTOX® is also injected into the skin to treat the symptoms of severe underarm sweating (severe primary axillary hyperhidrosis) when medicines used on the skin (topical) do not work well enough in people 18 years and older.
BOTOX® Cosmetic is a prescription medicine that is injected into muscles and used to improve the look of moderate to severe frown lines between the eyebrows (glabellar lines) in people 18 to 65 years of age for a short period of time (temporary).
It is not known whether BOTOX® and BOTOX® Cosmetic is safe or effective to prevent headaches in patients with migraine who have 14 or fewer headache days each month (episodic migraine).
It is not known whether BOTOX® and BOTOX® Cosmetic is safe or effective to treat increased stiffness in upper-limb muscles other than those in the elbow, wrist, and fingers, or to treat increased stiffness in lower-limb muscles. BOTOX® has not been shown to help people perform task-specific functions with their upper limbs or increase movement in joints that are permanently fixed in position by stiff muscles. Treatment with BOTOX® is not meant to replace your existing physical therapy or other rehabilitation that your doctor may have prescribed.
It is not known whether BOTOX® and BOTOX® Cosmetic are safe or effective for severe sweating anywhere other than your armpits.
IMPORTANT SAFETY INFORMATION
BOTOX® and BOTOX® Cosmetic may cause serious side effects that can be life threatening. Call your doctor or get medical help right away if you have any of these problems any time (hours to weeks) after injection of BOTOX® or BOTOX® Cosmetic:
Problems swallowing, speaking, or breathing, due to weakening of associated muscles, can be severe and result in loss of life. You are at the highest risk if these problems are pre-existing before injection. Swallowing problems may last for several months
Spread of toxin effects. The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms including: loss of strength and all-over muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice (dysphonia), trouble saying words clearly (dysarthria), loss of bladder control, trouble breathing, trouble swallowing. If this happens, do not drive a car, operate machinery, or do other dangerous activities
There has not been a confirmed serious case of spread of toxin effect away from the injection site when BOTOX® has been used at the recommended dose to treat chronic migraine, severe underarm sweating, blepharospasm, strabismus, or when BOTOX® Cosmetic has been used at the recommended dose to treat frown lines.
Do not take BOTOX® or BOTOX® Cosmetic if you: are allergic to any of the ingredients in BOTOX® (see Medication Guide for ingredients); had an allergic reaction to any other botulinum toxin product such as Myobloc® (rimabotulinumtoxinB), Dysport® (abobotulinumtoxinA), or Xeomin® (incobotulinumtoxinA); have a skin infection at the planned injection site.
Do not take BOTOX® for the treatment of urinary incontinence if you: have a urinary tract infection (UTI) or cannot empty your bladder on your own and are not routinely catheterizing.
Due to the risk of urinary retention (not being able to empty the bladder), only patients who are willing and able to initiate catheterization post-treatment, if required, should be considered for treatment.
Patients treated for overactive bladder
In clinical trials, 6.5% of patients (36/552) initiated clean intermittent catheterization for urinary retention following treatment with BOTOX® 100 Units as compared to 0.4% of patients (2/542) treated with placebo. The median duration of catheterization for these patients treated with BOTOX® 100 Units was 63 days (minimum 1 day to maximum 214 days) as compared to a median duration 11 days (minimum 3 days to maximum 18 days) for patients receiving placebo.
Patients with diabetes mellitus treated with BOTOX® were more likely to develop urinary retention than non-diabetics.
Patients treated for overactive bladder due to neurologic disease
In clinical trials, 30.6% of patients (33/108) who were not using clean intermittent catheterization (CIC) prior to injection, required catheterization for urinary retention following treatment with BOTOX® 200 Units as compared to 6.7% of patients (7/104) treated with placebo. The median duration of post-injection catheterization for these patients treated with BOTOX® 200 Units (n=33) was 289 days (minimum 1 day to maximum 530 days) as compared to a median duration 358 days (minimum 2 days to maximum 379 days) for patients receiving placebo (n=7).
Among patients not using CIC at baseline, those with MS were more likely to require CIC post-injection than those with SCI.
The dose of BOTOX® and BOTOX® Cosmetic is not the same as, or comparable to, another botulinum toxin product.
Serious and/or immediate allergic reactions have been reported. These reactions include itching, rash, red itchy welts, wheezing, asthma symptoms, or dizziness or feeling faint. Tell your doctor or get medical help right away if you experience any such symptoms; further injection of BOTOX® or BOTOX® Cosmetic should be discontinued.
Tell your doctor about all your muscle or nerve conditions such as amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease), myasthenia gravis, or Lambert-Eaton syndrome, as you may be at increased risk of serious side effects including severe dysphagia (difficulty swallowing) and respiratory compromise (difficulty breathing) from typical doses of BOTOX® or BOTOX® Cosmetic.
Tell your doctor if you have any breathing-related problems. Your doctor will want to monitor you for any breathing problems during your treatment with BOTOX® for upper limb spasticity or for detrusor overactivity associated with a neurologic condition. The risk of pulmonary effects in patients with compromised respiratory status is increased in patients receiving BOTOX®.
Cornea problems have been reported. Cornea (surface of the eye) problems have been reported in some people receiving BOTOX® for their blepharospasm, especially in people with certain nerve disorders. BOTOX® may cause the eyelids to blink less, which could lead to the surface of the eye being exposed to air more than is usual. Tell your doctor if you experience any problems with your eyes while receiving BOTOX®. Your doctor may treat your eyes with drops, ointments, contact lenses, or with an eye patch.
Bleeding behind the eye has been reported. Bleeding behind the eyeball has been reported in some people receiving BOTOX® for their strabismus. Tell your doctor if you notice any new visual problems while receiving BOTOX®.
Bronchitis and upper respiratory tract infections (common colds) have been reported. Bronchitis was reported more frequently in people receiving BOTOX® for their upper limb spasticity. Upper respiratory infections (common colds) were also reported more frequently in people with prior breathing-related problems.
Autonomic Dysreflexia in Patients Treated for Detrusor Overactivity Associated With a Neurologic Condition
Autonomic dysreflexia associated with intradetrusor injections of BOTOX® could occur in patients treated for detrusor overactivity associated with a neurologic condition and may require prompt medical therapy. In clinical trials, the incidence of autonomic dysreflexia was greater in patients treated with BOTOX® 200 Units compared with placebo (1.5% versus 0.4%, respectively).
Human albumin and spread of viral diseases. BOTOX® and BOTOX® Cosmetic contains albumin, a protein component of human blood. The potential risk of spreading viral diseases (eg, Creutzfeldt-Jakob disease [CJD]) via human serum albumin is extremely rare. No cases of viral diseases or CJD have ever been reported in association with human serum albumin.
Tell your doctor about all your medical conditions, including if you: have or have had bleeding problems; have plans to have surgery; had surgery on your face; weakness of forehead muscles, such as trouble raising your eyebrows; drooping eyelids; any other abnormal facial change; have symptoms of a urinary tract infection (UTI) and are being treated for urinary incontinence. Symptoms of a urinary tract infection may include pain or burning with urination, frequent urination, or fever; have problems emptying your bladder on your own and are being treated for urinary incontinence; are pregnant or plan to become pregnant (it is not known if BOTOX® or BOTOX® Cosmetic can harm your unborn baby); are breastfeeding or plan to breastfeed (it is not known if BOTOX® or BOTOX® Cosmetic passes into breast milk).
Tell your doctor about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal products. Using BOTOX® or BOTOX® Cosmetic with certain other medicines may cause serious side effects. Do not start any new medicines until you have told your doctor that you have received BOTOX® or BOTOX® Cosmetic in the past.
Especially tell your doctor if you: have received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc®, Dysport®, or Xeomin® in the past (be sure your doctor knows exactly which product you received); have recently received an antibiotic by injection; take muscle relaxants; take an allergy or cold medicine; take a sleep medicine; take anti-platelets (aspirin-like products) or anti-coagulants (blood thinners).
Other side effects of BOTOX® and BOTOX® Cosmetic include: dry mouth, discomfort or pain at the injection site, tiredness, headache, neck pain, and eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of your eyelids, and dry eyes. In people being treated for urinary incontinence, other side effects include: urinary tract infection, painful urination, and/or inability to empty your bladder on your own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters to empty your bladder up to a few times each day until your bladder is able to start emptying again.
For more information refer to the Medication Guide or talk with your doctor.
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.

BOTOX® Demonstrates Efficacy in Reducing Urinary Leakage Episodes
IRVINE, CA, USA I January 18, 2013 I Allergan, Inc. (NYSE:AGN) announced today that the U.S. Food and Drug Administration (FDA) has approved BOTOX® (onabotulinumtoxinA) for the treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency and frequency in adults who have had an inadequate response to or are intolerant of an anticholinergic medication. In two double-blind, randomized, multi-center, placebo-controlled 24-week clinical trials among adults with overactive bladder who had not been adequately managed with anticholinergic treatments, BOTOX® reduced daily urinary incontinence (leakage) episodes as compared to placebo by 50 percent or more by week 12 (reduction of 2.5 episodes from baseline of 5.5 episodes in one study and reduction of 3 episodes from baseline of 5.5 episodes in the second study for those treated with BOTOX® vs. a reduction of 0.9 episodes from a baseline of 5.1 episodes in one study and a reduction of 1.1 episodes from a baseline of 5.7 episodes in the second study for those treated with placebo).1

OAB Clinical Development Program
The FDA approval of BOTOX® was based on safety and efficacy data from two double-blind, randomized, multi-center, placebo-controlled 24-week clinical studies of 1,105 adult patients whose OAB symptoms had not been adequately managed with anticholinergic therapy, either due to lack of efficacy or intolerance of the medication. To qualify for the study, patients had to have symptoms of OAB with symptoms of urge urinary incontinence, urgency and frequency, and experience a minimum of three urinary urgency leakage (incontinence) episodes and at least 24 urination episodes (micturitions) over a three-day timeframe. Patients in the studies were randomized to receive physician-administered treatment with 100 units of BOTOX® neurotoxin (n=557) or placebo (n=548) injected directly into the detrusor (bladder) muscle. Patients were treated in the physician’s office and received a local anesthetic, with or without sedation, to numb the bladder prior to treatment with BOTOX® or placebo.
In both clinical trials, patients treated with BOTOX® experienced a reduction of 50% or more in the frequency of daily urinary incontinence episodes from baseline compared to placebo at week 12 (reduction of 2.5 episodes from baseline of 5.5 episodes in one study and reduction of 3 episodes from baseline of 5.5 episodes in the second study for those treated with BOTOX® vs. a reduction of 0.9 episodes from a baseline of 5.1 episodes in one study and a reduction of 1.1 episodes from a baseline of 5.7 episodes in the second study for those treated with placebo).1 In addition, approximately three times as many patients treated with BOTOX® in the clinical studies achieved a complete elimination of their leakage episodes as compared to placebo (22.9% and 31.4% achieved complete continence with BOTOX® vs. 6.5% and 10.3% with placebo at week 12 in the two clinical trials).5 Improvements in other symptoms of overactive bladder, including urge to urinate, frequency of urination and the amount of urine voided also occurred with BOTOX® treatment compared to placebo at week 12.
In the clinical studies, the most frequently reported adverse reactions within 12 weeks of receiving BOTOX® injections included urinary tract infection (18% vs. 6% with placebo), dysuria (9% vs. 7% with placebo), which means painful or difficult urination; and urinary retention (6.5% vs. 0.4% with placebo), which is a temporary inability to fully empty the bladder requiring the use of a disposable self-catheter.

BOTOX® (onabotulinumtoxinA) & BOTOX® Cosmetic (onabotulinumtoxinA) Important Information
Indications
BOTOX® is a prescription medicine that is injected into muscles and used:
to treat overactive bladder symptoms such as a strong need to urinate with leaking or wetting accidents (urge urinary incontinence), a strong need to urinate right away (urgency), and urinating often (frequency) in adults 18 years and older when another type of medicine (anticholinergic) does not work well enough or cannot be taken.
to treat leakage of urine (incontinence) in adults 18 years and older with overactive bladder due to neurologic disease who still have leakage or cannot tolerate the side effects after trying an anticholinergic medication
to prevent headaches in adults with chronic migraine who have 15 or more days each month with headache lasting 4 or more hours each day in people 18 years or older
to treat increased muscle stiffness in elbow, wrist, and finger muscles in people 18 years and older with upper limb spasticity
to treat the abnormal head position and neck pain that happens with cervical dystonia (CD) in people 16 years and older
to treat certain types of eye muscle problems (strabismus) or abnormal spasm of the eyelids (blepharospasm) in people 12 years and older
BOTOX® is also injected into the skin to treat the symptoms of severe underarm sweating (severe primary axillary hyperhidrosis) when medicines used on the skin (topical) do not work well enough in people 18 years and older.
BOTOX® Cosmetic is a prescription medicine that is injected into muscles and used to improve the look of moderate to severe frown lines between the eyebrows (glabellar lines) in people 18 to 65 years of age for a short period of time (temporary).
It is not known whether BOTOX® and BOTOX® Cosmetic is safe or effective to prevent headaches in patients with migraine who have 14 or fewer headache days each month (episodic migraine).
It is not known whether BOTOX® and BOTOX® Cosmetic is safe or effective to treat increased stiffness in upper-limb muscles other than those in the elbow, wrist, and fingers, or to treat increased stiffness in lower-limb muscles. BOTOX® has not been shown to help people perform task-specific functions with their upper limbs or increase movement in joints that are permanently fixed in position by stiff muscles. Treatment with BOTOX® is not meant to replace your existing physical therapy or other rehabilitation that your doctor may have prescribed.
It is not known whether BOTOX® and BOTOX® Cosmetic are safe or effective for severe sweating anywhere other than your armpits.
IMPORTANT SAFETY INFORMATION
BOTOX® and BOTOX® Cosmetic may cause serious side effects that can be life threatening. Call your doctor or get medical help right away if you have any of these problems any time (hours to weeks) after injection of BOTOX® or BOTOX® Cosmetic:
Problems swallowing, speaking, or breathing, due to weakening of associated muscles, can be severe and result in loss of life. You are at the highest risk if these problems are pre-existing before injection. Swallowing problems may last for several months
Spread of toxin effects. The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms including: loss of strength and all-over muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice (dysphonia), trouble saying words clearly (dysarthria), loss of bladder control, trouble breathing, trouble swallowing. If this happens, do not drive a car, operate machinery, or do other dangerous activities
There has not been a confirmed serious case of spread of toxin effect away from the injection site when BOTOX® has been used at the recommended dose to treat chronic migraine, severe underarm sweating, blepharospasm, strabismus, or when BOTOX® Cosmetic has been used at the recommended dose to treat frown lines.
Do not take BOTOX® or BOTOX® Cosmetic if you: are allergic to any of the ingredients in BOTOX® (see Medication Guide for ingredients); had an allergic reaction to any other botulinum toxin product such as Myobloc® (rimabotulinumtoxinB), Dysport® (abobotulinumtoxinA), or Xeomin® (incobotulinumtoxinA); have a skin infection at the planned injection site.
Do not take BOTOX® for the treatment of urinary incontinence if you: have a urinary tract infection (UTI) or cannot empty your bladder on your own and are not routinely catheterizing.
Due to the risk of urinary retention (not being able to empty the bladder), only patients who are willing and able to initiate catheterization post-treatment, if required, should be considered for treatment.
Patients treated for overactive bladder
In clinical trials, 6.5% of patients (36/552) initiated clean intermittent catheterization for urinary retention following treatment with BOTOX® 100 Units as compared to 0.4% of patients (2/542) treated with placebo. The median duration of catheterization for these patients treated with BOTOX® 100 Units was 63 days (minimum 1 day to maximum 214 days) as compared to a median duration 11 days (minimum 3 days to maximum 18 days) for patients receiving placebo.
Patients with diabetes mellitus treated with BOTOX® were more likely to develop urinary retention than non-diabetics.
Patients treated for overactive bladder due to neurologic disease
In clinical trials, 30.6% of patients (33/108) who were not using clean intermittent catheterization (CIC) prior to injection, required catheterization for urinary retention following treatment with BOTOX® 200 Units as compared to 6.7% of patients (7/104) treated with placebo. The median duration of post-injection catheterization for these patients treated with BOTOX® 200 Units (n=33) was 289 days (minimum 1 day to maximum 530 days) as compared to a median duration 358 days (minimum 2 days to maximum 379 days) for patients receiving placebo (n=7).
Among patients not using CIC at baseline, those with MS were more likely to require CIC post-injection than those with SCI.
The dose of BOTOX® and BOTOX® Cosmetic is not the same as, or comparable to, another botulinum toxin product.
Serious and/or immediate allergic reactions have been reported. These reactions include itching, rash, red itchy welts, wheezing, asthma symptoms, or dizziness or feeling faint. Tell your doctor or get medical help right away if you experience any such symptoms; further injection of BOTOX® or BOTOX® Cosmetic should be discontinued.
Tell your doctor about all your muscle or nerve conditions such as amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease), myasthenia gravis, or Lambert-Eaton syndrome, as you may be at increased risk of serious side effects including severe dysphagia (difficulty swallowing) and respiratory compromise (difficulty breathing) from typical doses of BOTOX® or BOTOX® Cosmetic.
Tell your doctor if you have any breathing-related problems. Your doctor will want to monitor you for any breathing problems during your treatment with BOTOX® for upper limb spasticity or for detrusor overactivity associated with a neurologic condition. The risk of pulmonary effects in patients with compromised respiratory status is increased in patients receiving BOTOX®.
Cornea problems have been reported. Cornea (surface of the eye) problems have been reported in some people receiving BOTOX® for their blepharospasm, especially in people with certain nerve disorders. BOTOX® may cause the eyelids to blink less, which could lead to the surface of the eye being exposed to air more than is usual. Tell your doctor if you experience any problems with your eyes while receiving BOTOX®. Your doctor may treat your eyes with drops, ointments, contact lenses, or with an eye patch.
Bleeding behind the eye has been reported. Bleeding behind the eyeball has been reported in some people receiving BOTOX® for their strabismus. Tell your doctor if you notice any new visual problems while receiving BOTOX®.
Bronchitis and upper respiratory tract infections (common colds) have been reported. Bronchitis was reported more frequently in people receiving BOTOX® for their upper limb spasticity. Upper respiratory infections (common colds) were also reported more frequently in people with prior breathing-related problems.
Autonomic Dysreflexia in Patients Treated for Detrusor Overactivity Associated With a Neurologic Condition
Autonomic dysreflexia associated with intradetrusor injections of BOTOX® could occur in patients treated for detrusor overactivity associated with a neurologic condition and may require prompt medical therapy. In clinical trials, the incidence of autonomic dysreflexia was greater in patients treated with BOTOX® 200 Units compared with placebo (1.5% versus 0.4%, respectively).
Human albumin and spread of viral diseases. BOTOX® and BOTOX® Cosmetic contains albumin, a protein component of human blood. The potential risk of spreading viral diseases (eg, Creutzfeldt-Jakob disease [CJD]) via human serum albumin is extremely rare. No cases of viral diseases or CJD have ever been reported in association with human serum albumin.
Tell your doctor about all your medical conditions, including if you: have or have had bleeding problems; have plans to have surgery; had surgery on your face; weakness of forehead muscles, such as trouble raising your eyebrows; drooping eyelids; any other abnormal facial change; have symptoms of a urinary tract infection (UTI) and are being treated for urinary incontinence. Symptoms of a urinary tract infection may include pain or burning with urination, frequent urination, or fever; have problems emptying your bladder on your own and are being treated for urinary incontinence; are pregnant or plan to become pregnant (it is not known if BOTOX® or BOTOX® Cosmetic can harm your unborn baby); are breastfeeding or plan to breastfeed (it is not known if BOTOX® or BOTOX® Cosmetic passes into breast milk).
Tell your doctor about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal products. Using BOTOX® or BOTOX® Cosmetic with certain other medicines may cause serious side effects. Do not start any new medicines until you have told your doctor that you have received BOTOX® or BOTOX® Cosmetic in the past.
Especially tell your doctor if you: have received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc®, Dysport®, or Xeomin® in the past (be sure your doctor knows exactly which product you received); have recently received an antibiotic by injection; take muscle relaxants; take an allergy or cold medicine; take a sleep medicine; take anti-platelets (aspirin-like products) or anti-coagulants (blood thinners).
Other side effects of BOTOX® and BOTOX® Cosmetic include: dry mouth, discomfort or pain at the injection site, tiredness, headache, neck pain, and eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of your eyelids, and dry eyes. In people being treated for urinary incontinence, other side effects include: urinary tract infection, painful urination, and/or inability to empty your bladder on your own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters to empty your bladder up to a few times each day until your bladder is able to start emptying again.
