What should I know about itraconazole capsules before taking them?

Do not stop taking itraconazole (Sporanox) capsules early, even if you feel better. This drug may take up to a year to cure some fungal infections. You should not take it if you have congestive heart failure. You might not be able to take itraconazole capsules if you have a heart rhythm disorder, problems with circulation, have had a stroke, COPD, kidney or liver disease, cystic fibrosis, or have a history of "Long QT syndrome."  Itraconazole capsules require an acidic environment in the stomach for optimal absorption; therefore, do not take stomach acid reducers (such as Axid, Pepcid, Tagamet, Zantac, omeprazole, esomeprazole, pantoprazole, rabeprazole or lansoprazole) or antacids within one hour before you take itraconazole capsules or two hours afterward. These drugs can lower your body's ability to absorb itraconazole.  Itraconazole capsules can have dangerous interactions with a variety of other drugs, so tell your doctor about all medications you are taking.

Make sure your doctor knows about all medications that you take, and do not start taking any new prescription or over-the-counter medications or supplements without asking your doctor.
