What should I watch for?
Tell your doctor if your symptoms do not get better or if they get worse. Visit your doctor or health care professional for regular checks on your progress. Because it may take several weeks to see the full effects of this medicine, it is important to continue your treatment as prescribed by your doctor.
Patients and their families should watch out for new or worsening thoughts of suicide or depression. Also watch out for sudden changes in feelings such as feeling anxious, agitated, panicky, irritable, hostile, aggressive, impulsive, severely restless, overly excited and hyperactive, or not being able to sleep. If this happens, especially at the beginning of treatment or after a change in dose, call your health care professional.
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. Alcohol may interfere with the effect of this medicine. Avoid alcoholic drinks.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water will help. Contact your doctor if the problem does not go away or is severe.
