Composition Active Ingredient: Oseltamivir Phosphate (pro-drug of oseltamivir) Strength: 75 mg oseltamivir per capsule Equivalent to approximately 98.5 mg oseltamivir phosphate in the formulation (depending on manufacturer) Dosage Form: Hard Gelatin Capsule Route: Oral administration Pharmacological Class Class: Antiviral agent — neuraminidase inhibitor Mechanism of Action: Oseltamivir is activated in the body to oseltamivir carboxylate, which inhibits the neuraminidase enzyme on influenza viruses (A and B), preventing new virions from being released from infected cells and limiting spread of the infection. Therapeutic Uses (Indications) This medicine is prescribed for: ✔ Treatment of acute, uncomplicated influenza (flu) in adults and children (when influenza virus is circulating and symptoms are present). ✔ Prevention (prophylaxis) of influenza infection after exposure in high-risk individuals (as directed by clinician). Dosage & Administration Adults & Adolescents (≥13 years): • Treatment: 75 mg twice daily for 5 days • Prophylaxis: 75 mg once daily for up to 10 days (or longer during outbreaks) Take orally, with or without food (taking with food may reduce stomach upset). Swallow capsules whole — do not chew or crush. Pediatric dosing and renal adjustments vary by weight and kidney function — follow physician instructions. Oseltavac 75 (Oseltamivir) capsules are antiviral medicines used to treat and prevent influenza (the flu) by stopping the virus from spreading in the body, relieving symptoms like fever, cough, sore throat, and body aches, and reducing complications, especially when taken early. It's used for Influenza A & B and H1N1 (Swine Flu), both for active infections and post-exposure prevention in individuals (1 year+) or during outbreaks. Treatment of Flu: Alleviates symptoms (fever, cough, runny nose, body aches, fatigue) and shortens illness duration when started within 48 hours of symptoms. Prevention of Flu: Can prevent illness in those exposed to the virus or during a pandemic, as advised by a doctor. Reduces Complications: Helps high-risk individuals (elderly, underlying conditions) avoid severe complications like pneumonia. Specific Viruses: Effective against Influenza A, Influenza B, and H1N1 (Swine Flu). How it Works: Contains oseltamivir, a neuraminidase inhibitor. Blocks viral enzymes, stopping the virus from entering and spreading to healthy cells.
