Uses for posaconazole

Posaconazole injection is used to prevent certain fungal (yeast) infections (for example, invasive Aspergillus or Candida infections) in patients who have a weakened immune system (for example, hematopoietic stem cell transplant or HSCT recipients, or patients with blood cancers).

Posaconazole injection is also used to treat invasive aspergillosis.

This medicine should only be given by a doctor or under the direct supervision of a doctor.

Precautions while using posaconazole

It is very important for your doctor to check your progress at regular visits. This will help your doctor see if the medicine is working properly and decide if you should continue taking it. Blood tests will be needed to check for unwanted effects.

You should not use atorvastatin (Lipitor®), lovastatin (Mevacor®), pimozide (Orap®), quinidine (Quinaglute®), simvastatin (Zocor®), sirolimus (Rapamune®), venetoclax (Venclexta®), or ergotamine medicines (for example, bromocriptine, dihydroergotamine, ergonovine, ergotamine, methylergonovine, methysergide, Cafergot®, Ergomar®, Wigraine®). Using any of them with this medicine may increase the chance of unwanted effects.

This medicine can cause changes in heart rhythms, including QT prolongation and torsades de pointes. Check with your doctor right away if you have chest pain or discomfort, fainting, an irregular or slow heart rate, or trouble breathing.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow skin or eyes. These could be symptoms of a serious liver problem.

Check with your doctor right away if you have severe diarrhea or vomiting while using this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

Before using posaconazole

In deciding to use a drug, the risks of taking the medication must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Inform your physician if you have ever had any unusual or allergic reaction to this medicine or any other medications. Additionally tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of posaconazole injection in children younger than 2 years of age to prevent fungus infections. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated pediatric-specific issues that would limit the usefulness of posaconazole injection in children 13 years of age and older to treat invasive aspergillosis. Safety and efficacy have been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific issues that would limit the usefulness of posaconazole injection in the elderly.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medicine during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
