Oseltamivir

Drug Details

Oseltamivir, commonly known as Tamiflu, is an antiviral medication designed to treat and prevent influenza (flu) types A and B. It is effective in reducing the severity of flu symptoms, like a stuffy nose, cough, sore throat, fever, chills, aches, and tiredness, and can decrease recovery time by 1 to 2 days if taken within 48 hours of symptom onset. Additionally, oseltamivir can help prevent the flu in individuals who have been in close contact with someone infected or during a community flu outbreak. Oseltamivir functions as a neuraminidase inhibitor, which blocks a protein on the flu virus, preventing it from multiplying and spreading in the body. While helpful in managing flu symptoms, it is not a replacement for the flu vaccine. This medication is available by prescription only and can be administered to individuals 2 weeks of age and older for treatment and 1 year and older for prevention. It is offered in capsule form or as a fruit-flavored liquid. Some common side effects include nausea and vomiting. Always consult a healthcare professional before starting any new medication.
