What It's For & How To Take
Itraconazole is an antifungal medication that works to slow the growth of certain types of fungus. This medication may be used to prevent and treat fungal infections throughout the body, including vaginal, oral, throat, abdominal, blood and other organs that may be infected.
In general, our body keeps a steady balance of healthy fungus and bacteria. The balance might be changed by antibiotics, steroids, chemotherapy or other situations that stress your body. When this happens, the fungus grows more easily in your body.
Itraconazole capsules are usually taken 1 or 2 times daily. This medication should be taken with a full meal. If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
Avoid taking antacids or any medication that decreases the acid in your stomach either 1 hour before or 2 hours after you take itraconazole. This medication will not work as well when taken with antacids.
Take this medication until it is all done, even if you are feeling better and the symptoms are gone. Stopping the medication too soon may allow for the fungus to come back only after a short time. If you notice that your symptoms are not getting better, call your doctor.
