Flugal 150 mg is a medication containing Fluconazole, an antifungal agent used to treat a variety of fungal infections. It works by inhibiting the production of ergosterol, a vital component of fungal cell membranes, which ultimately disrupts the cell's structure and leads to its death. Fluconazole is commonly prescribed for conditions like vaginal yeast infections, oral and esophageal candidiasis, systemic fungal infections, and cryptococcal meningitis. It may also be used for the prevention of fungal infections in immunocompromised individuals, such as those with HIV/AIDS or organ transplant recipients. While it is generally well-tolerated, common side effects include nausea, headache, dizziness, and abdominal pain. Serious side effects, such as liver problems and heart rhythm disturbances, are rare but possible. It is important to follow the prescribed dosage and consult a healthcare provider for any potential drug interactions or precautions, particularly in pregnant individuals or those with liver conditions. Flugal 150 mg is widely available in pharmacies, particularly in Bangladesh, and should be used under the guidance of a healthcare professional.
