About Posanex Oral Suspension

Posanex Oral Suspension is in a class of medications called azole antifungals. It is used to prevent and treat fungal infections when other antifungal medicines have not worked, or you have had to stop taking them. It is also indicated for preventing invasive Aspergillus and Candida infections in patients at high risk of developing these infections due to being severely immunocompromised, such as hematopoietic stem cell transplant (HSCT) recipients with graft-versus-host disease (GVHD) or those with hematologic malignancies with prolonged neutropenia from chemotherapy.

Posanex Oral Suspension contains a medicine called posaconazole. It is a triazole antifungal agent and exerts its antifungal activity through the blockage of certain enzymes (P-450 dependent enzyme, sterol 14α-demethylase). This leads to inhibiting the synthesis of ergosterol, a key component of the fungal cell membrane, and the accumulation of methylated sterol precursors. This results in the inhibition of fungal cell growth and cell death. Thus, it treats infections.

Take Posanex Oral Suspension as prescribed by your doctor. You are advised to take Posanex Oral Suspension for as long as your doctor has prescribed it based on your medical condition. In some cases, you may experience diarrhoea, nausea, fever, vomiting, headache, coughing and low potassium levels in the blood. Most of these side effects of Posanex Oral Suspension do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

Inform your doctor if you are allergic or hypersensitive to any component present in Posanex Oral Suspension or if you are pregnant, suspect you are pregnant, plan to have a baby or are breastfeeding; your doctor will prescribe Posanex Oral Suspension only if the benefits outweigh the risk.

Fungal infections affecting body organs like the lungs can cause flu or tuberculosis. Some fungal diseases like cryptococcal meningitis and blood infections can be fatal. A few common fungal infections are yeast infections that affect the genital area, oesophagus, and urinary tract caused by Candida.

Invasive aspergillosis: Invasive aspergillosis occurs when Aspergillus causes serious infection and usually affects people with weakened immune systems, such as those who have had an organ transplant or a stem cell transplant.
