Fapvir Tablet contains Favipiravir 200mg, an antiviral medication primarily used to treat viral infections such as influenza and certain RNA virus-related illnesses. 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. This medication is often prescribed for the treatment of mild to moderate cases of viral infections and has been explored for use in emerging viral diseases under medical supervision. Fapvir Tablet should be taken exactly as prescribed by a healthcare professional, typically with or without food, and the full course of treatment must be completed to ensure effectiveness and reduce the risk of resistance. Common side effects may include mild gastrointestinal discomfort, elevated liver enzymes, and transient increases in uric acid levels. It is contraindicated in pregnant women due to potential teratogenic effects and should be used cautiously in patients with liver or kidney impairment. Patients are advised to inform their doctor about any other medications they are taking to avoid potential drug interactions. Regular monitoring by a healthcare provider is recommended during the course of therapy to assess response and manage any adverse effects.
