What should I watch for?

Visit your doctor or health care professional for regular checks on your progress. Because your condition and the use of this medicine carries some risk, it is a good idea to carry an identification card, necklace or bracelet with details of your condition, medications and doctor or health care professional.

Check your blood pressure and pulse rate regularly. Ask your health care professional what your blood pressure and pulse rate should be, and when you should contact him or her. Your doctor or health care professional also may schedule regular blood tests and electrocardiograms to check your progress.

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 can make you more dizzy, increase flushing and rapid heartbeats. Avoid alcoholic drinks.
