Fabiflu 400 Tablet contains Favipiravir 400mg, an antiviral medication primarily used to treat influenza and certain viral infections by inhibiting viral RNA-dependent RNA polymerase, thereby preventing viral replication. It is commonly prescribed for managing mild to moderate cases of viral illnesses, including COVID-19, under medical supervision. Fabiflu is typically administered orally and should be taken exactly as directed by a healthcare professional to ensure optimal effectiveness and minimize potential side effects. Common side effects may include mild gastrointestinal discomfort, headache, and elevated liver enzymes, though serious adverse reactions are rare. It is important to inform your doctor about any pre-existing medical conditions, allergies, or concurrent medications to avoid drug interactions. Fabiflu is not recommended for use during pregnancy or breastfeeding unless specifically advised by a physician due to potential risks to the fetus or infant. Patients should complete the full prescribed course even if symptoms improve early to prevent viral resistance. Regular monitoring by a healthcare provider is advised during treatment. Store Fabiflu tablets in a cool, dry place away from direct sunlight and out of reach of children. Always consult a healthcare professional before starting or stopping this medication.
