Product introduction

Posatral 300mg Injection is an antifungal medicine used to prevent and treat severe fungal infections, particularly in people with weakened immune systems. It is commonly prescribed to prevent invasive infections caused by Aspergillus and Candida species and to treat fungal infections of the mouth and throat.

Do not self-administer this medicine. Your doctor or nurse will teach you the correct way of injecting it. To get the most benefit, take this medicine at evenly spaced times and continue using it until your prescription is finished, even if your symptoms disappear after a few days. If you stop treatment too early, the infection may return and if you miss doses you can increase your risk of infections that are resistant to further treatment.

The most common side effects of this medicine include diarrhea, nausea, fever, vomiting, headache, coughing, and hypokalemia. These are not usually serious, but you should call your doctor if you think you might have a severe allergic reaction and signs of liver problems such as yellowing of eyes, dark urine, and stomach problems. Get emergency help if this happens.

Do not take it if you are pregnant or could become pregnant unless your doctor has told you to. Talk to your doctor before taking it if you have ever had heart failure, kidney problems, or liver problems such as yellow skin (jaundice). This medicine may not be suitable for you. If your course of treatment is for more than a month, your doctor may want to check your liver, and potassium level by testing your blood. This medicine may make you dizzy or have blurred vision so do not drive or operate machines until it is safe.

How Posatral Injection works

Posatral 300mg Injection is an antifungal that works by inhibiting the enzyme essential for the synthesis of ergosterol, a key component of fungal cell membranes. It disrupts the production of ergosterol, damaging the fungal cell membrane, leading to cell death. This action makes it effective in preventing and treating invasive Aspergillus and Candida infections in immunocompromised patients, as well as treating oropharyngeal candidiasis, including cases resistant to other azoles like itraconazole or fluconazole.
