  • What is Botox?

    Botox is a medicine used to treat leakage of urine (incontinence) in people with overactive bladder due to neurologic disease; to prevent headaches in people with chronic (long term) migraine; to treat increased muscle stiffness in elbow, wrist, or finger muscles in people with upper limb involuntary muscle contractions; to treat the abnormal head position and neck pain that happens with cervical dystonia; or to treat certain types of eye muscle problems or abnormal spasm of the eyelids. Botox can also be used to treat the symptoms of severe underarm sweating when medicines used on the skin do not work well. Botox may also be used to treat other conditions, as determined by your doctor. Botox is administered intramuscularly (injected into the muscle), intradetrusorly (injected into the bladder), or intradermally (injected into the skin).
