Oseltamivir 75 mg capsules are a very well-known antiviral medication used for the treatment and prevention of influenza A and B (also known as the flu). Marketed under brand names like Tamiflu, Oseltamivir belongs to a class of drugs called neuraminidase inhibitors, which work by blocking the action of the influenza virus in the body. By inhibiting the viral enzyme neuraminidase, Oseltamivir prevents the virus from spreading to other cells, helping to reduce the severity and duration of flu symptoms.

Oseltamivir 75 mg is most effective when taken within 48 hours of the onset of flu symptoms. It helps relieve common flu symptoms such as fever, chills, sore throat, cough, runny nose, muscle aches, fatigue, and headache. In clinical studies, patients treated with Oseltamivir have shown quicker recovery times and a reduced risk of complications such as bronchitis, pneumonia, and hospitalization—especially in high-risk groups like the elderly, young children, and individuals with chronic health conditions.

In addition to treatment, Oseltamivir 75 mg capsules are also prescribed for the prevention of influenza, particularly for people who have been exposed to the flu virus or during flu outbreaks in closed environments such as nursing homes or schools. When used as a preventive measure, it significantly lowers the risk of contracting the flu.

The standard adult dosage for treatment is 75 mg twice daily for 5 days, while for prevention, the recommended dosage is 75 mg once daily for at least 10 days, depending on the exposure risk. Oseltamivir can be taken with or without food, though taking it with food may help reduce stomach upset.

Oseltamivir is generally well tolerated. Common side effects include nausea, vomiting, headache, and abdominal discomfort. These side effects are typically mild and short-lived. In rare cases, serious side effects such as allergic reactions or neuropsychiatric symptoms may occur, particularly in pediatric patients. It’s important to seek medical advice if any unusual behavior or adverse effects are observed.

Whether used for early flu treatment or prevention, Oseltamivir 75 mg capsules provide effective antiviral protection, helping individuals recover faster and reduce the risk of complications during flu season. Always consult your healthcare provider for appropriate dosage and medical guidance.
