What should I watch for?

Visit your doctor or health care professional for regular checks on your progress. Contact your doctor or health care professional promptly if you develop an unusual or severe headache or have changes in your vision.

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 find that you have sudden feelings of wanting to sleep during normal activities, like cooking, watching television, or while driving or riding in a car, you should contact your health care professional.

You may get a false-positive result for sugar in your urine. Check with your doctor or health care professional.

Learn how to check your blood sugar. Learn the symptoms of low and high blood sugar and how to manage them.

If you have low blood sugar, eat or drink something that has sugar. Make sure others know to get medical help quickly if you have serious symptoms of low blood sugar, like if you become unconscious or have a seizure.

Wear a medical identification bracelet or chain to say you have diabetes, and carry a card that lists all your medications.
