Boxed Warning

WARNING: DISTANT SPREAD OF TOXIN EFFECT Postmarketing reports indicate that the effects of BOTOX and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to the se symptoms. In unapproved uses and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia an d spasticity and at lower doses [ see Warnings and Precautions ( 5.1 )] .

Indications and usage

1 INDICATIONS AND USAGE BOTOX is an acetylcholine release inhibitor and a neuromuscular blocking agent indicated for: Treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency, and frequency, in adults who have an inadequate response to or are intolerant of an anticholinergic medication ( 1.1 ) 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 ( 1.1 ) Treatment of neurogenic detrusor overactivity (NDO) in pediatric patients 5 years of age and older who have an inadequate response to or are intolerant of anticholinergic medication. ( 1.2 ) Prophylaxis of headaches in adult patients with chronic migraine (≥15 days per month with headache lasting 4 hours a day or longer) ( 1.3 ) Treatment of spasticity in patients 2 years of age and older ( 1.4 ) Treatment of cervical dystonia in adult patients, to reduce the severity of abnormal head position and neck pain ( 1.5 ) Treatment of severe axillary hyperhidrosis that is inadequately managed by topical agents in adult patients ( 1.6 ) Treatment of blepharospasm associated with dystonia in patients 12 years of age and older ( 1.7 ) Treatment of strabismus in patients 12 years of age and older ( 1.7 ) Limitations of Use Safety and effectiveness of BOTOX have not been established for: Prophylaxis of episodic migraine (14 headache days or fewer per month) ( 1.3 ) Treatment of hyperhidrosis in body areas other than axillary ( 1.6 ) 1.1 Adult Bladder Dysfunction Overactive Bladder BOTOX for injection is indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency, in adults who have an inadequate response to or are intolerant of an anticholinergic medication. Detrusor Overactivity associated with a Neurologic Condition BOTOX is indicated for the treatment of urinary incontinence due to detrusor overactivity associated with a neurologic condition (e.g., SCI, MS) in adults who have an inadequate response to or are intolerant of an anticholinergic medication. 1.2 Pediatric Detrusor Overactivity A ssociated with a Neurologic Condition BOTOX is indicated for the treatment of neurogenic detrusor overactivity (NDO) in pediatric patients 5 years of age and older who have an inadequate response to or are intolerant of anticholinergic medication. 1. 3 Chronic Migraine BOTOX is indicated for the prophylaxis of headaches in adult patients with chronic migraine (≥15 days per month with headache lasting 4 hours a day or longer). Limitations of Use Safety and effectiveness have not been established for the prophylaxis of episodic migraine (14 headache days or fewer per month) in seven placebo-controlled studies. 1. 4 Spasticity BOTOX is indicated for the treatment of spasticity in patients 2 years of age and older. Limitations of Use BOTOX has not been shown to improve upper extremity functional abilities, or range of motion at a joint affected by a fixed contracture. 1. 5 Cervical Dystonia BOTOX is indicated for the treatment of adults with cervical dystonia, to reduce the severity of abnormal head position and neck pain associated with cervical dystonia. 1. 6 Primary Axillary Hyperhidrosis BOTOX is indicated for the treatment of severe primary axillary hyperhidrosis that is inadequately managed with topical agents. Limitations of Use The safety and effectiveness of BOTOX for hyperhidrosis in other body areas have not been established. Weakness of hand muscles and blepharoptosis may occur in patients who receive BOTOX for palmar hyperhidrosis and facial hyperhidrosis, respectively. Patients should be evaluated for potential causes of secondary hyperhidrosis (e.g., hyperthyroidism) to avoid symptomatic treatment of hyperhidrosis without the diagnosis and/or treatment of the underlying disease.

Dosage and administration

2 DOSAGE AND ADMINISTRATION Follow indication-specific dosage and administration recommendations. In a 3 month interval, do not exceed a total dose of: • Adults: 400 Units • Pediatrics: the lesser of 10 Units/kg or 340 Units ( 2.1 ) See Preparation and Dilution Technique for instructions on BOTOX reconstitution, storage, and preparation before injection ( 2.2 ) Overactive Bladder: Recommended total dose 100 Units, as 0.5 mL (5 Units) injections across 20 sites into the detrusor ( 2.3 ) Adult Detrusor Overactivity associated with a Neurologic Condition: Recommended total dose 200 Units, as 1 mL (~6.7 Units) injections across 30 sites into the detrusor ( 2.3 ) Pediatric Detrusor Overactivity associated with a Neurologic Condition: 0.5 mL injections across 20 sites into the detrusor ( 2.4 ) • Greater than or equal to 34 kg: Recommended total dose is 200 Units • Less than 34 kg: Recommended total dose is 6 Units/kg Chronic Migraine: Recommended total dose 155 Units, as 0.1 mL (5 Units) injections per each site divided across 7 head/neck muscles ( 2.5 ) Adult Upper Limb Spasticity: Recommended total dose up to 400 Units divided among affected muscles ( 2.6 ) Adult Lower Limb Spasticity: Recommended total dose 300 Units to 400 Units divided across ankle and toe muscles ( 2.6 ) Pediatric Upper Limb Spasticity: Recommended total dose 3 Units/kg to 6 Units/kg (maximum 200 Units) divided among affected muscles ( 2.7 ) Pediatric Lower Limb Spasticity: Recommended total dose 4 Units/kg to 8 Units/kg (maximum 300 Units) divided among affected muscles ( 2.7 ) Cervical Dystonia: Base dosing on the patient’s head and neck position, localization of pain, muscle hypertrophy, patient response, and adverse event history; use lower initial dose in botulinum toxin naïve patients ( 2.8 ) Axillary Hyperhidrosis: 50 Units per axilla ( 2.9 ) Blepharospasm: 1.25 Units-2.5 Units into each of 3 sites per affected eye ( 2.10 ) Strabismus: The dose is based on prism diopter correction or previous response to treatment with BOTOX ( 2.11 ) 2.1 Instructions for Safe Use The potency Units of BOTOX (onabotulinumtoxinA) for injection are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method [see Warnings and Precautions ( 5.2 ) and Description ( 11 )] . Indication specific dosage and administration recommendations should be followed. When initiating treatment, the lowest recommended dose should be used. In treating adult patients for one or more indications, the maximum cumulative dose should not exceed 400 Units, in a 3-month interval. In pediatric patients, the total dose should not exceed the lower of 10 Units/kg body weight or 340 Units, in a 3-month interval [see Dosage and Administration ( 2.7 )] . The safe and effective use of BOTOX depends upon proper storage of the product, selection of the correct dose, and proper reconstitution and administration techniques. An understanding of standard electromyographic techniques is also required for treatment of strabismus, upper or lower limb spasticity, and may be useful for the treatment of cervical dystonia. Physicians administering BOTOX must understand the relevant neuromuscular and structural anatomy of the area involved and any alterations to the anatomy due to prior surgical procedures and disease, especially when injecting near the lungs. Do not use BOTOX and contact AbbVie (1-800-678-1605) if: the tamper evident features on the carton appear to be broken or compromised, or the U.S. License number 1889 is not present on the vial label and carton labeling [see How Supplied/Storage and Handling ( 16 )] . 2.2 Preparation and Dilution Technique Prior to injection, reconstitute each vacuum-dried vial of BOTOX with only sterile, preservative-free 0.9…

Warnings

5 WARNINGS AND PRECAUTIONS Spread of toxin effects; swallowing and breathing difficulties can lead to death. Seek immediate medical attention if respiratory, speech or swallowing difficulties occur ( 5.1 , 5.6 ) Potency Units of BOTOX are not interchangeable with other preparations of botulinum toxin products ( 5.2 , 11 ) Potential serious adverse reactions after BOTOX injections for unapproved uses ( 5.3 ) Concomitant neuromuscular disorder may exacerbate clinical effects of treatment ( 5.5 ) Use with caution in patients with compromised respiratory function ( 5.6 , 5.7 , 5.10 ) Corneal exposure and ulceration due to reduced blinking may occur with BOTOX treatment of blepharospasm ( 5.8 ) Retrobulbar hemorrhages and compromised retinal circulation may occur with BOTOX treatment of strabismus ( 5.9 ) Bronchitis and upper respiratory tract infections in patients treated for spasticity ( 5.10 ) Urinary tract infections in patients treated for OAB ( 5.12 ) Urinary retention: Post-void residual urine volume should be monitored in patients treated for OAB or adult detrusor overactivity associated with a neurologic condition who do not catheterize routinely, particularly patients with multiple sclerosis or diabetes mellitus. ( 5.13 ) 5. 1 Spread of Toxin Effect Postmarketing safety data from BOTOX and other approved botulinum toxins suggest that botulinum toxin effects may, in some cases, be observed beyond the site of local injection. The symptoms are consistent with the mechanism of action of botulinum toxin and may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence, and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death related to spread of toxin effects. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, and particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses and in approved indications, symptoms consistent with spread of toxin effect have been reported at doses comparable to or lower than doses used to treat cervical dystonia and spasticity. Patients or caregivers should be advised to seek immediate medical care if swallowing, speech or respiratory disorders occur. No definitive serious adverse event reports of distant spread of toxin effect associated with BOTOX for blepharospasm at the recommended dose (30 Units and below), severe primary axillary hyperhidrosis at the recommended dose (100 Units), strabismus, or for chronic migraine at the labeled doses have been reported. 5.2 Lack of Interchangeability between Botulinum Toxin Products The potency Units of BOTOX are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method [see Description ( 11 )] . 5.3 Serious Adverse Reactions with Unapproved Use Serious adverse reactions, including excessive weakness, dysphagia, and aspiration pneumonia, with some adverse reactions associated with fatal outcomes, have been reported in patients who received BOTOX injections for unapproved uses. In these cases, the adverse reactions were not necessarily related to distant spread of toxin, but may have resulted from the administration of BOTOX to the site of injection and/or adjacent structures. In several of the cases, patients had pre-existing dysphagia or other significant disabilities. There is insufficient information to identify factors associated with an increased risk for adverse reactions associated with the unapproved uses of BOTOX. The sa…

Contraindications

4 CONTRAINDICATIONS BOTOX is contraindicated: In patients who are hypersensitive to any botulinum toxin product or to any of the components in the formulation [see Warnings and Precautions ( 5.4 )] . In the presence of infection at the proposed injection site(s). For intradetrusor injection in patients with a urinary tract infection; or in patients with urinary retention or post-void residual (PVR) urine volume >200 mL who are not routinely performing clean intermittent self-catheterization (CIC) [see Warnings and Precautions ( 5.12 , 5.13 )] . Hypersensitivity to any botulinum toxin preparation or to any of the components in the formulation ( 4 , 5.4 , 6 ) Infection at the proposed injection site ( 4 ) Intradetrusor Injections: Urinary tract infection or urinary retention ( 4 )

Drug interactions

7 DRUG INTERACTIONS Patients receiving concomitant treatment of BOTOX and aminoglycosides or other agents interfering with neuromuscular transmission (e.g., curare-like agents), or muscle relaxants, should be observed closely because the effect of BOTOX may be potentiated ( 7.1 , 7.4 ) 7.1 Aminoglycosides and Other Agents Interfering with Neuromuscular Transmission Co-administration of BOTOX and aminoglycosides or other agents interfering with neuromuscular transmission (e.g., curare-like compounds) should only be performed with caution as the effect of the toxin may be potentiated. 7.2 Anticholinergic Drugs Use of anticholinergic drugs after administration of BOTOX may potentiate systemic anticholinergic effects. 7.3 Other Botulinum Neurotoxin Products The effect of administering different botulinum neurotoxin products at the same time or within several months of each other is unknown. Excessive neuromuscular weakness may be exacerbated by administration of another botulinum toxin prior to the resolution of the effects of a previously administered botulinum toxin. 7.4 Muscle Relaxants Excessive weakness may also be exaggerated by administration of a muscle relaxant before or after administration of BOTOX.

Pregnancy

8.1 Pregnancy Risk Summary There are no studies or adequate data from postmarketing surveillance on the developmental risk associated with use of BOTOX in pregnant women. In animal studies, administration of BOTOX during pregnancy resulted in adverse effects on fetal growth (decreased fetal weight and skeletal ossification) at clinically relevant doses, which were associated with maternal toxicity [see Data ]. In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated populations is unknown. Data Animal Data When BOTOX (4, 8, or 16 Units/kg) was administered intramuscularly to pregnant mice or rats two times during the period of organogenesis (on gestation days 5 and 13), reductions in fetal body weight and decreased fetal skeletal ossification were observed at the two highest doses. The no-effect dose for developmental toxicity in these studies (4 Units/kg) is approximately equal to the human dose of 400 Units, on a body weight basis (Units/kg). When BOTOX was administered intramuscularly to pregnant rats (0.125, 0.25, 0.5, 1, 4, or 8 Units/kg) or rabbits (0.063, 0.125, 0.25, or 0.5 Units/kg) daily during the period of organogenesis (total of 12 doses in rats, 13 doses in rabbits), reduced fetal body weights and decreased fetal skeletal ossification were observed at the two highest doses in rats and at the highest dose in rabbits. These doses were also associated with significant maternal toxicity, including abortions, early deliveries, and maternal death. The developmental no-effect doses in these studies of 1 Unit/kg in rats and 0.25 Units/kg in rabbits are less than the human dose of 400 Units, based on Units/kg. When pregnant rats received single intramuscular injections (1, 4, or 16 Units/kg) at three different periods of development (prior to implantation, implantation, or organogenesis), no adverse effects on fetal development were observed. The developmental no-effect level for a single maternal dose in rats (16 Units/kg) is approximately 2 times the human dose of 400 Units, based on Units/kg.

Adverse reactions (label)

6 ADVERSE REACTIONS The following adverse reactions to BOTOX (onabotulinumtoxinA) for injection are discussed in greater detail in other sections of the labeling: Spread of Toxin Effects [see Warnings and Precautions ( 5.1 )] Serious Adverse Reactions with Unapproved Use [see Warnings and Precautions ( 5.3 )] Hypersensitivity Reactions [see Contraindications ( 4 ) a nd Warnings and Precautions ( 5.4 )] Increased Risk of Clinically Significant Effects with Pre-Existing Neuromuscular Disorders [see Warnings and Precautions ( 5.5 )] Dysphagia and Breathing Difficulties [see Warnings and Precautions ( 5.6 )] Pulmonary Effects of BOTOX in Patients with Compromised Respiratory Status Treated for Spasticity or for Detrusor Overactivity Associated with a Neurologic Condition [see Warnings and Precautions ( 5.7 )] Corneal Exposure and Ulceration in Patients Treated with BOTOX for Blepharospasm [see Warnings and Precautions ( 5.8 )] Retrobulbar Hemorrhages in Patients Treated with BOTOX for Strabismus [see Warnings and Precautions ( 5.9 )] Bronchitis and Upper Respiratory Tract Infections in Patients Treated for Spasticity [se e Warnings and Precautions ( 5.10 )] Autonomic Dysreflexia in Patients Treated for Detrusor Overactivity Associated with a Neurologic Condition [see Warnings and Precautions ( 5.11 )] Urinary Tract Infections in Patients with Overactive Bladder [see Warnings and Precautions ( 5.12 )] Urinary Retention in Patients Treated for Bladder Dysfunction [see Warnings and Precautions ( 5.13 )] The most common adverse reactions (≥5% and >placebo, if applicable) are ( 6.1 ): OAB: urinary tract infection, dysuria, urinary retention Adult Detrusor Overactivity associated with a neurologic condition: urinary tract infection, urinary retention Pediatric Detrusor Overactivity associated with a neurologic condition: urinary tract infection, leukocyturia, bacteriuria Chronic Migraine: neck pain, headache Adult Spasticity: pain in extremity Pediatric Spasticity: upper respiratory tract infection Cervical Dystonia: dysphagia, upper respiratory infection, neck pain, headache, increased cough, flu syndrome, back pain, rhinitis Axillary Hyperhidrosis: injection site pain and hemorrhage, non-axillary sweating, pharyngitis, flu syndrome To report SUSPECTED ADVERSE REACTIONS, contact AbbVie at 1-800-678-1605 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. BOTOX and BOTOX Cosmetic contain the same active ingredient in the same formulation, but with different labeled Indications and Usage. Therefore, adverse reactions observed with the use of BOTOX Cosmetic also have the potential to be observed with the use of BOTOX. In general, adverse reactions occur within the first week following injection of BOTOX and, while generally transient, may have a duration of several months or longer. Localized pain, infection, inflammation, tenderness, swelling, erythema, and/or bleeding/bruising may be associated with the injection. Symptoms associated with flu-like symptoms (e.g., nausea, fever, myalgia) have been reported after treatment. Needle-related pain and/or anxiety may result in vasovagal responses (including syncope, hypotension), which may require appropriate medical therapy. Local weakness of the injected muscle(s) represents the expected pharmacological action of botulinum toxin. However, weakness of nearby muscles may also occur due to spread of toxin [see Warnings and Precautions ( 5.1 )] . Overactive Bladder Table 14 presents the most frequently reported adverse reactions in double-blind, placebo-controlled clinical trials for overactive bladder occurring within 12 weeks of the first BOTOX treatment.
