What should my health care professional know before I take ketoconazole?
They need to know if you have any of these conditions:
• an alcohol abuse problem
• 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
• pregnant or trying to get pregnant
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 if I miss a dose?
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
