Proper Use

Drug information provided by: Micromedex

Itraconazole oral solution works differently than itraconazole capsules, even at the same dose (number of milligrams). Do not switch from the capsules to the oral solution unless your doctor tells you to.

Keep using this medicine for the full treatment time, even if you feel better after the first few doses. Your infection may not clear up if you stop using the medicine too soon.

This medicine comes with a patient information leaflet. Read and follow the instructions in the leaflet carefully. Talk with your doctor if you have any questions.

Itraconazole capsules and tablets should be taken with a full meal. The oral liquid is best taken on an empty stomach.

Take the tablets at the same time each day.

Measure the oral liquid with a marked measuring spoon or medicine cup. If you have thrush in the mouth or throat, place 10 milliliters (mL) of the liquid in your mouth, swish it in the mouth for several seconds, and then swallow it. Repeat these steps if your total dose is more than 10 mL.

If you are using antacids (e.g., Maalox®, Mylanta®, Pepcid® Complete, Rolaids®, or Tums®), take the antacid at least 1 hour before or 2 hours after taking itraconazole.
