What is Diflucan?

Diflucan (fluconazole) is an antifungal antibiotic.

Diflucan is used to treat infections caused by fungus, which can invade any part of the body including the mouth, throat, esophagus, lungs, bladder, genital area, and the blood.

Diflucan is also used to prevent fungal infection in people with weak immune systems caused by cancer treatment, bone marrow transplant, or diseases such as AIDS.

Diflucan may also be used for purposes not listed in this medication guide.

Important information

Do not use Diflucan if you are allergic to fluconazole, or similar drugs such as clotrimazole (Lotrimin), econazole (Spectazole), ketoconazole (Nizoral), miconazole (Monistat, Oravig), sertaconazole (Ertaczo), sulconazole (Exelderm), terconazole (Terazol), tioconazole (Vagistat-1), or voriconazole (Vfend). You should not use Diflucan if you are also taking cisapride (Propulsid).

Before taking Diflucan, tell your doctor if you have liver disease, kidney disease, a heart rhythm disorder, or a history of Long QT syndrome.

Take Diflucan for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antifungal medication. Diflucan will not treat a viral infection such as the common cold or flu.

How should I take Diflucan?

Take Diflucan exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Your dose will depend on the infection you are treating. Vaginal infections are often treated with only one pill. For other infections, your first dose may be a double dose. Carefully follow your doctor's instructions. Tell your doctor if your symptoms do not improve.

Take Diflucan with a full glass of water. Shake the oral suspension (liquid) well just before you measure a dose. To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one. Take Diflucan for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antifungal medication.

Diflucan will not treat a viral infection such as the common cold or flu.

Store Diflucan tablets at room temperature away from moisture and heat. You may store liquid Diflucan in a refrigerator, but do not allow it to freeze. Throw away any leftover liquid medicine that is more than 2 weeks old.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include confusion or unusual thoughts or behavior.

What should I avoid?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
