Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start taking posaconazole and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with food as directed by your doctor, usually twice daily for the first day, and then once daily after that. Do not take this medication at the same time with alcohol or with medications that contain alcohol. Doing so can release all of the drug at once, increasing the risk of side effects.

Follow instructions on how to prepare and mix the suspension. Do not open the powder packet until you are ready to prepare the medication. Only use the mixing liquid provided in the kit to mix the powder. Do not use any other liquid to mix. Shake the medication well before using. The suspension should look cloudy and free of clumps. Carefully measure the dose using the provided measuring syringe. Do not use a household spoon because you may not get the correct dose. After mixing, the medication should be used within 1 hour. Discard any unused suspension.

The dosage and length of treatment are based on your medical condition and weight.

For the best effect, take this antifungal at evenly spaced times. To help you remember, take this medication at the same time every day.

Continue to take this medication until the full prescribed amount is finished. Stopping the medication too early may result in the medication not working well.

This form of posaconazole may deliver different amounts of medication than the tablet and regular-release suspension forms. Do not switch between the different forms of this medication without your doctor's permission and directions.

Tell your doctor if you have severe diarrhea or vomiting. Posaconazole may not work as well. If you are giving this medication to a small child, tell the doctor if the child is unable to take the full dose or is spitting out the medication.
