What is the most important information I should know about voriconazole?
Do not use voriconazole if you are pregnant. It could harm the unborn baby.
There are many other medicines that can cause serious or life-threatening drug interactions with voriconazole. Tell your doctor about all the prescription and over-the-counter medications you use.
Before taking voriconazole, tell your doctor if you have heart rhythm problems, an electrolyte imbalance, liver or kidney disease, or a history of allergy to other antifungal medications such as fluconazole (Diflucan), ketoconazole (Nizoral), or itraconazole (Sporanox).
Take this medication 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 antibiotics. Voriconazole will not treat a viral infection such as the common cold or flu.
Voriconazole can cause problems with your vision. If you use this medicine for more than 28 days, you may need to have your eyes checked.
What should I discuss with my healthcare provider before taking voriconazole?

cisapride (Propulsid);
pimozide (Orap);
quinidine (Quin-G);
sirolimus (Rapamune);

St. John's wort; or
an ergot medicine such as ergotamine (Ergomar, Cafergot, Ercaf, Wigraine, others) or dihydroergotamine (D.H.E., Migranal).
The drugs listed above can cause dangerous serious or life-threatening drug interactions with voriconazole. Tell your doctor about all other medicines you are using.
To make sure you can safely take voriconazole, tell your doctor if you have any of these other conditions:

How should I take voriconazole?
Take 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.
Take voriconazole at least one hour before or after eating a meal. Shake the oral suspension (liquid) well just before you measure a dose. Measure the liquid with a special dose-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. Do not mix the oral suspension with any other medicine or liquid. Take this medication 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 antibiotics. Voriconazole will not treat a viral infection such as the common cold or flu.
To be sure voriconazole is helping your condition, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Visit your doctor regularly.

Store voriconazole tablets at room temperature away from moisture and heat. Store the oral liquid at room temperature for up to 14 days. Throw away any unused liquid after 14 days.
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 vision problems, excessive mouth watering, enlarged pupils, weakness, loss of balance, shortness of breath, or seizure (convulsions).
What should I avoid while taking voriconazole?

Be careful if you drive or do anything that requires you to have clear vision. Avoid exposure to sunlight or tanning beds. Voriconazole can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
