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.
Your health care provider may suggest that you have your eyes examined prior to starting this medicine, and every 6 months thereafter.
If you have been taking this medicine regularly for some time, do not suddenly stop taking it. You must gradually reduce the dose or your symptoms may get worse. Ask your doctor or health care professional for advice.
Patients and their families should watch out for worsening depression or thoughts of suicide. Also watch out for sudden or severe 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 antidepressant 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.
This medicine can reduce the response of your body to heat or cold. Dress warm in cold weather and stay hydrated in hot weather. If possible, avoid extreme temperatures like saunas, hot tubs, very hot or cold showers, or activities that can cause dehydration such as vigorous exercise.
