What should I tell my health care provider before I take this medicine?
They need to know if you have any of these conditions:

low stomach acid production (achlorhydria or hypochlorhydria)
liver disease
other chronic illness
an unusual or allergic reaction to ketoconazole, itraconazole, miconazole, other foods, dyes or preservatives

How should I take this medicine?
Take ketoconazole tablets by mouth. Follow the directions on the prescription label. Take your doses at regular intervals. Ketoconazole works best if you take it with food. If you have a low production of stomach acid you may have to take your tablets dissolved in dilute hydrochloric acid. Drink this mixture through a straw to avoid contact with the teeth. Then drink a glass of water, swishing it round your teeth before you swallow. Do not take or use your medicine more often than directed. Finish the full course prescribed by your prescriber or health care professional even if you feel better. Do not stop taking except on your prescriber's advice.
Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.

What should I watch for while taking ketoconazole?
Tell your prescriber or health care professional if your symptoms do not begin to improve in 1 to 2 weeks. Some fungal infections can take many weeks or months of treatment to cure. Take your medicine regularly for as long as your prescriber or health care professional tells you to.
You may get dizzy; until you know how ketoconazole affects you, do not drive, use machinery, or do anything that needs mental alertness.
Alcohol may make you more dizzy, feel sick and increase possible damage to your liver. Avoid alcoholic drinks while you are taking ketoconazole and for two days afterwards. Other medicines you get on prescription, or buy at the pharmacy may contain small amounts of alcohol.
Do not take terfenadine (Seldane®) or astemizole (Hismanal®) with ketoconazole. This combination of medicines can produce serious effects on your heart.
Ketoconazole may make your eyes more sensitive to light. Wear dark glasses in bright sun, or under any bright lights.
