Description
OnabotulinumtoxinA is used to treat certain eye conditions, such as blepharospasm (a condition where the eyelid will not stay open because of a muscle spasm) or strabismus (a condition where the eyes do not line up properly).
OnabotulinumtoxinA is also used to treat the abnormal head position and neck pain that result from cervical dystonia (severe muscle spasms of the neck) and some types of axillary hyperhidrosis (severe sweating of the armpits).
OnabotulinumtoxinA is used to treat increased muscle stiffness in the elbow, wrist, and finger muscles or ankle and toe muscles in adults with upper or lower limb spasticity or in children 2 to 17 years of age with upper and lower limb spasticity.
OnabotulinumtoxinA is also used to prevent headaches in patients with chronic migraine (severe headaches for 15 or more days a month lasting 4 or more hours a day).
OnabotulinumtoxinA is used cosmetically to temporarily improve the appearance of deep facial lines or wrinkles between the eyebrows (glabellar lines), forehead lines, and crow's feet lines around the eyes (lateral canthal lines).
OnabotulinumtoxinA is also used to treat urinary incontinence (loss of bladder control) in patients with an overactive bladder caused by nervous system disorders (eg, multiple sclerosis, spinal cord injury). It is also used to treat an overactive bladder caused by a nervous system disorder or overactive bladder with symptoms, such as loss of bladder control, increased urge to urinate, and frequent need to urinate in patients who have failed treatment with other medicines (eg, anticholinergics).
OnabotulinumtoxinA is a botulinum toxin A product. It works on the nervous system to relax the muscles.
OnabotulinumtoxinA is injected into the affected muscles. Depending on your condition, more than one treatment may be required.

Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of onabotulinumtoxinA in children. However, safety and effectiveness have not been established in children younger than 2 years of age for upper limb spasticity and lower limb spasticity (except spasms caused by cerebral palsy), in children younger than 5 years of age for overactive bladder caused by a nervous system disorder, in children younger than 12 years of age for blepharospasm or strabismus, in children younger than 16 years of age for cervical dystonia, or in children younger than 18 years of age for chronic migraine, hyperhidrosis, or overactive bladder with symptoms. Use of onabotulinumtoxinA to treat glabellar lines, forehead lines, and lateral canthal lines is not recommended in children.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of onabotulinumtoxinA in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving onabotulinumtoxinA.

Your doctor will give you this medicine in a medical facility. It is given as a shot under your skin or into one of your muscles.
You may be given medicine to numb the area where the shot will be injected. If you receive the medicine around your eyes, you may be given eye drops or ointment to numb the area. After your injection, you may need to wear a protective contact lens or eye patch.
If you are being treated for bladder problems, you may also receive medicine to help prevent urinary tract infection before, during, or after treatment with this medicine.
If you are treated for excessive sweating, shave your underarms but do not use deodorant for 24 hours before your injection. Avoid exercise, hot foods or liquids, or anything else that could make you sweat for 30 minutes before your injection.
This medicine works slowly. For neck disorders, you should have improvement within 2 to 6 weeks after your injection. For upper arm stiffness, you should have improvement within 4 to 6 weeks after your injection. Eyelid disorders should improve within 3 days to 2 weeks after your injection. Strabismus should improve within 1 or 2 days after the injection, and the improvement should last for 2 to 6 weeks. Once your condition has improved, the medicine will last about 3 months, then the effects of the medicine will slowly go away. You might need more injections when the effects of the medicine wear off. The recommended re-treatment schedule for chronic migraine is every 12 weeks.
This medicine should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.

Precautions
It is very important that your doctor check your or your child's progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it. Blood and urine tests may be needed to check for unwanted effects.

This medicine may make your muscles weak and cause vision problems (eg, bleeding inside the eye). Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

After you have received this medicine and your vision or muscle spasms are better, you may find that you are a lot more active than you were before. You should slowly increase your activities to allow time for your body to get stronger. Also, before you start an exercise program, check with your doctor.
