What should I watch for?
Visit your doctor or health care professional for regular checks on your progress. It can take several days before you feel the full effect of this medicine. If you have been taking this medicine regularly for some time, do not suddenly stop taking it. You must gradually reduce the dose or you may get severe side effects. Ask your doctor or health care professional for advice. Even after you stop taking this medicine it can still affect your body for several days.
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 increase dizziness and drowsiness. Avoid alcoholic drinks.
Do not treat yourself for coughs, colds, or allergies without asking your doctor or health care professional for advice. Some ingredients can increase possible side effects.
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.
