Unopened vials of BOTOX® should be stored in a refrigerator (2° to 8°C) for up to 36 months for the 100 U vial or up to 24 months for the 200 U vial. Do not use after the expiration date on the vial.1

After reconstituting BOTOX® in a vial, administer it within 24 hours of reconstitution. During this period, reconstituted BOTOX® should be stored in a refrigerator (2° to 8°C). Reconstituted BOTOX® should be clear, colorless, and free of particulate matter. Use immediately after reconstitution in a syringe.1

IndicationDetrusor Overactivity Associated With a Neurologic Condition BOTOX® for injection is indicated for the treatment of urinary incontinence due to detrusor overactivity associated with a neurologic condition (eg, SCI, MS) in adults who have an inadequate response to or are intolerant of an anticholinergic medication.IMPORTANT SAFETY INFORMATION, INCLUDING BOXED WARNING

CONTRAINDICATIONSBOTOX® is contraindicated in the presence of infection at the proposed injection site(s) and in individuals with known hypersensitivity to any botulinum toxin preparation or to any of the components in the formulation.Intradetrusor injection of BOTOX® is contraindicated in patients with detrusor overactivity associated with a neurologic condition who have acute urinary tract infection, and in patients with acute urinary retention who are not routinely performing clean intermittent self-catheterization (CIC).WARNINGS AND PRECAUTIONSLack 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.Spread of Toxin Effect See Boxed 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 these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and at lower doses.

Please see additional Important Safety Information on the next page.

WARNINGS AND PRECAUTIONS (cont.)Hypersensitivity Reactions Serious and/or immediate hypersensitivity reactions have been reported. These reactions include anaphylaxis, serum sickness, urticaria, soft-tissue edema, and dyspnea. If such a reaction occurs, further injection of BOTOX® should be discontinued and appropriate medical therapy immediately instituted. One fatal case of anaphylaxis has been reported in which lidocaine was used as the diluent, and consequently the causal agent cannot be reliably determined.Pre-Existing Neuromuscular Disorders Individuals with peripheral motor neuropathic diseases, amyotrophic lateral sclerosis, or neuromuscular junctional disorders (eg, myasthenia gravis or Lambert-Eaton syndrome) should be monitored particularly closely when given botulinum toxin. Patients with neuromuscular disorders may be at increased risk of clinically significant effects including severe dysphagia and respiratory compromise from therapeutic doses of BOTOX®.Pulmonary Effects of BOTOX® in Patients With Compromised Respiratory Status Treated for Detrusor Overactivity Associated With a Neurologic Condition Patients with compromised respiratory status treated with BOTOX® for detrusor overactivity associated with a neurologic condition should be monitored closely.Autonomic Dysreflexia and Urinary Retention 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).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=108) 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=104).Among patients not using CIC at baseline, those with MS were more likely to require CIC post-injection than those with SCI.Due to the risk of urinary retention, only patients who are willing and/or able to initiate catheterization post-treatment, if required, should be considered for treatment.In patients who are not catheterizing, post-void residual (PVR) urine volume should be assessed within 2 weeks post-treatment and periodically as medically appropriate up to 12 weeks. Catheterization should be instituted if PVR urine volume exceeds 200 mL and continued until PVR falls below 200 mL. Patients should be instructed to contact their physician if they experience difficulty in voiding as catheterization may be required.

Human Albumin and Transmission of Viral Diseases This product contains albumin, a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries an extremely remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD) is also considered extremely remote. No cases of transmission of viral diseases or CJD have ever been reported for albumin.ADVERSE REACTIONS The following adverse reactions to BOTOX® for injection are discussed in greater detail in the following sections: Spread of Toxin Effect (see Boxed Warning) and Hypersensitivity Reactions (see Contraindications and Warnings and Precautions).Detrusor Overactivity Associated With a Neurologic Condition The most frequently reported adverse reactions within 12 weeks of BOTOX® injection for detrusor overactivity associated with a neurologic condition include urinary tract infection (BOTOX® 24%, placebo 17%), urinary retention (BOTOX® 17%, placebo 3%), hematuria (BOTOX® 4%, placebo 3%), fatigue (BOTOX® 4%, placebo 1%), and insomnia (BOTOX® 2%, placebo 0%).The following adverse event rates were reported at any time following initial injection and prior to reinjection or study exit (median duration of 44 weeks of exposure): urinary tract infections (49%), urinary retention (17%), fatigue (6%), constipation (4%), muscular weakness (4%), dysuria (4%), fall (3%), gait disturbance (3%), insomnia (3%), and muscle spasm (2%).Post Marketing Experience There have been spontaneous reports of death, sometimes associated with dysphagia, pneumonia, and/or other significant debility or anaphylaxis, after treatment with botulinum toxin. There have also been reports of adverse events involving the cardiovascular system, including arrhythmia and myocardial infarction, some with fatal outcomes. Some of these patients had risk factors including cardiovascular disease. The exact relationship of these events to the botulinum toxin injection has not been established.DRUG INTERACTIONS No formal drug interaction studies have been conducted with BOTOX® (onabotulinumtoxinA) for injection. 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. Use of anticholinergic drugs after administration of BOTOX® may potentiate systemic anticholinergic effects. 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. Excessive weakness may also be exaggerated by administration of a muscle relaxant before or after administration of BOTOX®.Please see the accompanying full Prescribing Information, including Boxed Warning and Medication Guide.

5 WARNINGS AND PRECAUTIONS5.1 Lack of Interchangeability between Botulinum Toxin ProductsThe 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 Dosage and Administration (2.1), Description (11)].

5.2 Spread of Toxin EffectPostmarketingsafetydatafromBOTOXandotherapprovedbotulinumtoxinssuggestthatbotulinumtoxineffectsmay,insomecases,beobservedbeyondthesiteoflocalinjection.Thesymptomsareconsistentwiththemechanismofactionofbotulinumtoxinandmayincludeasthenia,generalizedmuscleweakness,diplopia,ptosis,dysphagia,dysphonia,dysarthria,urinaryincontinence,andbreathingdifficulties.Thesesymptomshavebeenreportedhourstoweeksafterinjection.Swallowingandbreathingdifficultiescanbelifethreateningandtherehavebeenreportsofdeathrelatedtospreadoftoxineffects.Theriskofsymptomsisprobablygreatestinchildrentreatedforspasticitybutsymptomscanalsooccurinadultstreatedforspasticityandotherconditions,andparticularlyinthosepatientswhohaveanunderlyingconditionthatwouldpredisposethemtothesesymptoms.Inunapproveduses,includingspasticityinchildren,andinapprovedindications,symptomsconsistentwithspreadoftoxineffecthavebeenreportedatdosescomparabletoorlowerthandosesusedtotreatcervicaldystonia.Patientsorcaregiversshouldbeadvisedtoseekimmediatemedicalcareifswallowing,speechorrespiratorydisordersoccur.
