FCN 200mg Tablet contains Fluconazole 200mg, an antifungal medication used to treat a variety of fungal infections. It works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting the integrity of the cell membrane and leading to the death of the fungal cells. FCN 200mg is commonly prescribed for infections such as candidiasis, including oropharyngeal, esophageal, and systemic candidiasis, as well as cryptococcal meningitis and other fungal infections caused by susceptible organisms. This medication is effective against a broad spectrum of fungi and is often preferred due to its oral administration and good bioavailability. It is important to take FCN 200mg exactly as prescribed by a healthcare professional, usually once daily, with or without food. Patients should complete the full course of treatment even if symptoms improve early to prevent recurrence. Common side effects may include headache, nausea, abdominal pain, and rash, though serious adverse reactions are rare. FCN 200mg should be used cautiously in patients with liver or kidney impairment, and potential drug interactions should be discussed with a healthcare provider. Pregnant or breastfeeding women should consult their doctor before use.
