How should I take Sporanox?

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

Do not share this medicine with another person, even if they have the same symptoms you have.

The capsule should be taken after a full meal.

Take oral solution (liquid) on an empty stomach, at least 1 hour before or 2 hours after a meal. Swish the liquid in your mouth for several seconds before swallowing it.

Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

The Sporanox PulsePak has a special dosing schedule that includes not taking the medicine for several days in a row. Follow all dosing instructions carefully.

Do not crush, chew, break, or open a capsule. Swallow the capsule whole.

Sporanox capsules should not be used in place of Sporanox oral solution (liquid) if that is what your doctor has prescribed. Make sure you have received the correct type of this medicine at the pharmacy and ask the pharmacist if you have any questions.

If you also take a stomach acid reducer (Tagamet, Pepcid, Axid, Zantac, and others), take Sporanox with an acidic drink such as non-diet cola.

Take this medicine 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 medicine. Itraconazole will not treat a viral infection such as the common cold or flu.

While using this medicine, you may need frequent blood tests.

Store at room temperature away from moisture, heat, and light.
