IncobotulinumtoxinA Injection

IncobotulinumtoxinA injection is used to treat a number of conditions.

IncobotulinumtoxinA injection is used to:

• treat chronic sialorrhea (ongoing drooling or excessive salivation) in adults and children 2 years of age and older;

• treat spasticity (muscle stiffness and tightness) of muscles in the arms in adults;

• treat spasticity (muscle stiffness and tightness) of muscles in the arms in children 2 years of age or older who do not have cerebral palsy (condition that causes difficulty with movement and balance);

• relieve the symptoms of cervical dystonia (spasmodic torticollis; uncontrollable tightening of the neck muscles that may cause neck pain and abnormal head positions) in adults;

• treat blepharospasm (uncontrollable tightening of the eyelid muscles that may cause blinking, squinting, and abnormal eyelid movements) in adults;

• and temporarily smooth frown lines (wrinkles between the eyebrows) in adults.

IncobotulinumtoxinA injection is in a class of medications called neurotoxins. When incobotulinumtoxinA injection is injected into saliva glands, it blocks the nerve signals that causes excessive saliva production. When incobotulinumtoxinA injection is injected into a muscle, it blocks the nerve signals that cause uncontrollable tightening and movements of the muscle.

IncobotulinumtoxinA injection comes as a powder to be mixed with a liquid and injected into the saliva glands or a muscle by a doctor. Your doctor will choose the best place to inject the medication in order to treat your condition. You may receive additional injections every 3–4 months, depending on your condition and on how long the effects of the treatment last.

Your doctor will probably start you on a low dose of incobotulinumtoxinA injection and gradually change your dose according to your response to the medication.

One brand or type of botulinum toxin cannot be substituted for another.

IncobotulinumtoxinA injection may help to control your condition, but will not cure it. It may take a few days or up to several weeks before you feel the full benefit of incobotulinumtoxinA injection.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
