Tetrabenazine Side Effects

What should I watch for?

Visit your doctor or health care professional for regular checks on your progress. It may be several weeks before you see the full effects of this medicine.

Patients and their families should watch out for worsening depression or thoughts of suicide. If this happens, especially at the beginning treatment or after a change in dose, call your health care professional.

You may get dizzy or drowsy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can increase dizziness and drowsiness. Avoid alcoholic drinks.
