How Is It Used?
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.

Tell your prescriber or health care professional
about all other medicines you are taking, including non-prescription
medicines, nutritional supplements, or herbal products. Also

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 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.
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.
