Indication BOTOX^® is 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. It is not known whether BOTOX^® is safe or effective for severe sweating anywhere other than your armpits. IMPORTANT SAFETY INFORMATION BOTOX^® 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^®:

• 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.

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 severe underarm sweating. The dose of BOTOX^® is not the same as, or comparable to, another botulinum toxin product. Serious and or immediate allergic reactions have been reported. These reactions include itchy rash, swelling, and shortness of breath. Tell your doctor or get medical help right away if you experience any such symptoms, further injection of BOTOX^® should be discontinued. Do not take BOTOX^® 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^® or Dysport^®; have a skin infection at the planned injection site. 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^®. Tell your doctor about all your medical conditions, including if you 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; are pregnant or plan to become pregnant (It is not known if BOTOX^® can harm your unborn baby); are breast-feeding or plan to breastfeed (It is not known if BOTOX^® passes into breast milk). Tell your doctor about all the medicines you take, including prescription and nonprescription medicines, vitamins and herbal products. BOTOX^® may cause loss of strength or general muscle weakness, or vision problems. If this happens, do not drive a car, operate machinery, or do other dangerous activities. Other side effects of BOTOX^® 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. 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.

Indications BOTOX^® is indicated for the treatment of severe primary axillary hyperhidrosis that is inadequately managed with topical agents. Important Limitations 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. Safety and effectiveness of BOTOX^® have not been established for the treatment of axillary hyperhidrosis in pediatric patients under age 18. IMPORTANT SAFETY INFORMATION INCLUDING 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 underlying conditions 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. CONTRAINDICATIONS BOTOX^® 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. WARNINGS AND PRECAUTIONS 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 or converted into Units of any other botulinum toxin products assessed with any other specific assay method. Spread of Toxin Effect See Boxed Warning. No definitive serious adverse event reports of distant spread of toxin effect associated with dermatologic use of BOTOX^® at the labeled dose of 100 Units (for severe primary axillary hyperhidrosis) have been reported. 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 typical doses of BOTOX^®. 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); Hypersensitivity Reactions (see Contraindications and Warnings and Precautions); Bronchitis and Upper Respiratory Tract Infections in Patients Treated for Spasticity (see Warnings and Precautions). Primary Axillary Hyperhidrosis The most frequently reported adverse events (3 - 10% of adult patients) following injection of BOTOX^® for severe primary axillary hyperhidrosis include injection site pain and hemorrhage, non-axillary sweating, infection, pharyngitis, flu syndrome, headache, fever, neck or back pain, pruritus, and anxiety. 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.
