Why is this medication prescribed?

Posaconazole is a prescription medication that belongs to the class of drugs known as antifungal agents. It is primarily prescribed for the treatment and prevention of various fungal infections.

Posaconazole is commonly used to treat invasive fungal infections caused by fungi such as Aspergillus and Candida. These infections can affect different parts of the body, including the lungs, bloodstream, and other organs. Posaconazole is often prescribed when other antifungal medications have not been effective or when the infection is resistant to other treatments.

In addition to its therapeutic uses, posaconazole may also be prescribed as a preventive measure for individuals who are at high risk of developing invasive fungal infections. This includes individuals with weakened immune systems, such as those undergoing chemotherapy or stem cell transplantation.

How should this medicine be used?

Posaconazole is available in different formulations, including oral suspension, delayed-release tablets, and intravenous (IV) injection. The specific form and dosing instructions will be determined by your healthcare provider based on your condition and needs. It is important to carefully follow their instructions and the medication label. Here are some general guidelines for the use of posaconazole:

• Oral Suspension: If you are prescribed the oral suspension form, shake the bottle well before each use to ensure proper mixing of the medication. Measure the prescribed dose using the provided oral dosing syringe or measuring cup. Take posaconazole with a full meal or liquid nutritional supplement to increase its absorption. Swallow the suspension directly without chewing or crushing any tablet particles that may be present.
• Delayed-Release Tablets: If you are prescribed the delayed-release tablets, take them with a full meal. Do not chew, crush, or break the tablets as they are designed to release the medication slowly.
• Intravenous (IV) Injection: If you are receiving posaconazole through an IV injection, it will be administered by a healthcare professional in a clinical setting. They will determine the appropriate dosage, dilution, and infusion rate based on your specific condition.

It is important to complete the full course of treatment as prescribed, even if your symptoms improve. Skipping doses or stopping the medication prematurely can increase the risk of the infection returning or becoming resistant to treatment.

If you have any questions or concerns about how to use posaconazole, it is recommended to consult your healthcare provider or pharmacist for detailed instructions and guidance. They will provide you with the most accurate and personalized information based on your specific situation.
