Noxafil is an antifungal medication used to treat or prevent certain types of fungal infections. It contains the active ingredient posaconazole. The active ingredient in Noxafil, posaconazole, is an antifungal medicine that belongs to the triazole group. It works by preventing the formation of ergosterol, which is an essential component of fungal cell membranes. By inhibiting the formation of ergosterol, posaconazole disrupts the cell membrane of the fungus, leading to its death.
Noxafil is used to treat fungal infections caused by Candida or Aspergillus, both of which can cause serious infections in people with compromised immune systems or medical conditions that weaken the immune system. Noxafil is available with a prescription and should only be used under the guidance of a healthcare professional. It is also available in delayed-release tablets, and oral suspension.
Uses and Dosage
Posaconazole is available in two forms: Noxafil Oral Suspension and Posaconazole Modified Release Tablet. Your doctor will direct you to take either form once a day by mouth with or without food. To use Posaconazole Modified Release Tablets, take the tablet orally by mouth with or without food as prescribed by your doctor. Make sure not to crush or chew the tablet, unless it has a score line, and your doctor or pharmacist instructs you to do so. Swallow the whole tablet, keeping it intact.
The duration of treatment depends on your medical condition. The tablet and suspension forms of posaconazole may contain different amounts of medication. Do not switch between these forms without your doctor's approval and instructions. If you experience severe diarrhea or vomiting, inform your doctor as the medication may not be as effective in such circumstances.
Take the medicine at evenly spaced intervals to ensure a consistent level of the drug in your body. The length of the treatment will depend on your medical condition, which will be determined by your doctor. In case you experience severe diarrhea or vomiting, contact your doctor as the medication may not be as effective in such situations.
