Fabiflu Tablet contains Favipiravir 200mg, an antiviral medication primarily used for the treatment of influenza and certain viral infections, including mild to moderate COVID-19 cases. Favipiravir works by inhibiting the RNA-dependent RNA polymerase enzyme, which is essential for viral replication, thereby preventing the virus from multiplying and spreading within the body. Fabiflu is typically prescribed to reduce the severity and duration of viral infections and is most effective when administered early in the course of the illness. The tablet is taken orally, usually twice daily, with or without food, as directed by a healthcare professional. Common side effects may include mild gastrointestinal discomfort, elevated liver enzymes, and transient increases in uric acid levels; however, serious adverse reactions are rare. It is important to avoid use during pregnancy due to potential teratogenic effects and to inform the physician of any pre-existing liver or kidney conditions before starting treatment. Fabiflu should be used under strict medical supervision, and patients are advised to complete the full course to ensure optimal efficacy and reduce the risk of viral resistance. This medication is a valuable option in managing viral infections when used appropriately and timely.
