What should I watch for?
Visit your doctor or health care professional for regular checks on your progress. Check your blood pressure as directed. Ask your doctor or health care professional what your blood pressure should be and when you should contact him or her. Call your doctor or health care professional if you notice an irregular or fast heart beat.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you.

If you are going to have surgery, tell your doctor or health care professional that you are taking this medicine.
