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.

What should I watch for while taking probucol?

Probucol will not cure your condition, but taken regularly it will help keep down your cholesterol level. Visit your prescriber or health care professional for regular checks on your progress. Do not stop taking probucol, except on your prescriber's advice.

Probucol is only part of a total cholesterol-lowering program. Your physician or dietician can suggest a low-cholesterol and low-fat diet that will reduce your risk of getting heart and blood vessel disease. Avoid alcohol and smoking, and keep a proper exercise schedule.

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

You may get dizzy; until you know how probucol affects you, do not drive, use machinery, or do anything that needs mental alertness. 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.

What side effects may I notice from taking probucol?

Side effects that you should report to your prescriber or health care professional as soon as possible:

  • chest pain

  • fainting spells

  • fast or irregular heartbeats (palpitations)

  • fever, chills

  • muscle aches or cramps

  • unusual bleeding or bruising

  • unusual tiredness or weakness

  • unusual swelling of the face, tongue, lips, hands or feet

Side effects that usually do not require medical attention (report to your prescriber or health care professional if they continue or are bothersome):

  • diarrhea

  • dizziness

  • headache

  • nausea, vomiting

  • upset stomach, gas, or heartburn
