Horizant Side Effects

What should I watch for?

Tell your doctor or healthcare professional if your symptoms do not start to get better or if they get worse. Do not stop taking except on your doctor's advice. You may develop a severe reaction. Your doctor will tell you how much medicine to take.

Alcohol may interfere with the effects of this medicine. Avoid alcoholic drinks.

You may get drowsy or dizzy. 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.

Patients and their families should watch out for worsening depression or thoughts of suicide. Any worsening of mood, or thoughts of suicide or dying should be reported to your health care professional right away.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
