Posaconazole
Summary
Posaconazole is used to treat and prevent fungal infections, which are illnesses caused by fungi. It's often prescribed for people with weakened immune systems, such as those undergoing chemotherapy or with HIV/AIDS, to help clear infections by stopping fungal growth.
Posaconazole works by inhibiting the growth of fungi, which are organisms that can cause infections. It belongs to a class of medications called triazole antifungals, which block an enzyme that fungi need to produce their cell membranes, helping to clear the infection.
The usual dose for adults starts with 300 mg twice on the first day, followed by 300 mg once daily. It's taken with food to help absorption. Dosage may vary for children, the elderly, or those with kidney or liver issues, and should be tailored by a doctor.
Common side effects of Posaconazole include nausea, which is feeling sick to your stomach, vomiting, which is throwing up, and diarrhea, which is loose or watery stools. These effects are usually mild and occur in a small percentage of people taking the medication.
Posaconazole can cause liver problems, which are issues with the organ that processes toxins, and affect heart rhythm, which is the pattern of heartbeats. It shouldn't be used by people with certain heart conditions. Always inform your doctor about your medical history and other medications.
