Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
Check your blood pressure and pulse rate regularly; this is important while you are taking mibefradil. Ask your prescriber or health care professional what your blood pressure and pulse rate should be and when you should contact him or her.
You may feel dizzy or lightheaded. Do not drive, use machinery, or do anything that needs mental alertness until you know how mibefradil 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. Avoid alcoholic drinks because they can make you more dizzy, increase flushing, and cause rapid heartbeats.
Do not suddenly stop taking mibefradil. Ask your prescriber or health care professional how you can gradually reduce the dose.
If you are going to have surgery, tell your prescriber or health care professional that you are taking mibefradil.
