Posaconazole Oral Administration
Before you begin taking posaconazole, and each time you get a refill, read the Patient Information Leaflet provided by your pharmacist. If you have any concerns, consult your doctor or pharmacist.
As directed by your doctor, take this medication by mouth with or without food once daily. Delayed-release tablets should not be crushed or chewed. This can result in the drug being released all at once, increasing the risk of side effects. Also, unless the tablets have a score line and your doctor or pharmacist instructs you to do so, do not split them. Without crushing or chewing, swallow the entire or split tablet.
The duration of treatment is determined by your medical condition.
This medication works best when the amount of medication in your body remains constant. Take this medication at regular intervals.

If you have severe diarrhoea or vomiting, contact your doctor. Posaconazole may not be as effective.
Nausea, vomiting, diarrhoea, headache, abdominal pain, dizziness, difficulty sleeping, or stomach upset are all possible side effects. Inform your doctor or pharmacist right away if any of these side effects persist or worsen.

Before taking this medication, inform your doctor or pharmacist of your medical history, particularly if you have: liver disease or kidney disease.
Posaconazole has been linked to a heart rhythm disorder (QT prolongation). QT prolongation can cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness and fainting) that require immediate medical attention.
If you have certain medical conditions or are taking other drugs that may cause QT prolongation, your risk of QT prolongation may be increased. Before taking posaconazole, inform your doctor or pharmacist of all the medications you are currently taking, as well as if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), a family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low potassium and magnesium levels in the blood may also increase your risk of QT prolongation. This risk may increase if you take certain medications (such as diuretics/”water pills”) or have conditions such as excessive sweating, diarrhoea, or vomiting. Consult your doctor about how to use posaconazole safely.
This medication may cause dizziness. You may become dizzy if you consume alcohol or marijuana (cannabis). Do not drive, operate machinery, or do anything else that requires alertness until you are sure you can do it safely. Consume no alcoholic beverages. If you use marijuana, talk to your doctor (cannabis). Alcohol may also increase the likelihood of developing serious liver problems.
Inform your doctor or dentist about all of the products you use before having surgery (including prescription drugs, nonprescription drugs, and herbal products).
Older adults may be more sensitive to the drug’s side effects, particularly QT prolongation (see above).
This medication should be used only when clearly necessary during pregnancy. Consult your doctor about the risks and benefits.
