Ketoconazole and the capsule form of itraconazole should be taken with a full meal. The oral solution form of itraconazole should be taken on an empty stomach. If you have any questions about the antifungal medicine you are taking, check with your health care professional.

For patients taking the oral liquid form of fluconazole, itraconazole, or ketoconazole :

• Use a specially marked measuring spoon or other device to measure each dose accurately. The average household teaspoon may not hold the right amount of liquid.

If you have achlorhydria (absence of stomach acid) or hypochlorhydria (decreased amount of stomach acid), and you are taking itraconazole or ketoconazole , your doctor may want you to take your medicine with an acidic drink. You may dissolve your medicine in cola or seltzer water and drink the solution, or your may take your medicine with a glass of cola or seltzer water. Your doctor may suggest that you dissolve each capsule or tablet in a teaspoonful of weak hydrochloric acid solution to help you absorb the medicine better. Your health care professional can prepare the solution for you. After you dissolve the tablet in the acid solution, add this mixture to a small amount (1 or 2 teaspoonfuls) of water in a glass. Drink the mixture through a plastic or glass drinking straw. Place the straw behind your teeth, as far back in your mouth as you can. This will keep the acid from harming your teeth. Be sure to drink all the liquid to get the full dose of medicine. Next, swish around in your mouth about one-half glass of water and then swallow it. This will help wash away any acid that may remain in your mouth or on your teeth.

To help clear up your infection completely, it is very important that you keep taking this medicine for the full time of treatment , even if your symptoms begin to clear up or you begin to feel better after a few days.
