What should I watch for while taking mexiletine?

Visit your prescriber or health care professional for regular checks on your progress. Do not stop taking mexiletine suddenly; this may cause serious, heart-related side effects. Because your condition and the use of mexiletine carry some risk. it is a good idea to carry an identification card, necklace or bracelet with details of your condition, medications and prescriber or health care professional.

Check your heart rate (pulse) and blood pressure regularly while you are taking mexiletine. Ask your prescriber or health care professional what your heart rate and blood pressure should be, and when you should contact him or her. Your prescriber or health care professional also may schedule regular blood tests and electrocardiograms to check your progress.

You may feel dizzy or faint. Do not drive, use machinery, or do anything that needs mental alertness until you know how mexiletine affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Alcohol can make you more dizzy, increase flushing and rapid heartbeats. Avoid alcoholic drinks.

If you are going to have surgery, tell your prescriber or health care professional that you are taking mexiletine.
