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.
Wear a medical ID bracelet or chain, and carry a card that describes your disease and details of your medicine and dosage times.
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.
If you are taking another medicine that also causes drowsiness, you may have more side effects. Give your health care provider a list of all medicines you use. Your doctor will tell you how much medicine to take. Do not take more medicine than directed. Call emergency for help if you have problems breathing or unusual sleepiness.
