Olsivir 75 mg Capsule is used for treatment and prevention of Influenza (flu).
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Olsivir 75 mg Capsule contains Oseltamivir Phosphate (75mg). It belongs to the Antiviral agent class of medicines.
Treatment and prevention of Influenza (flu)
Olsivir Capsule is a neuraminidase inhibitor. It inhibits neuraminidase (influenza virus enzyme), which helps the viruses to enter uninfected cells of the body to cause or spread influenza infection in the body. This is how it works against the virus to treat influenza (flu).
Take exactly as prescribed by your doctor.
Most side effects of Olsivir are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Antivirals work best when started early — within the first day or two of symptoms for most infections. Complete the course exactly as prescribed; stopping early can allow the virus to become resistant. Drink plenty of water, particularly with aciclovir and its relatives. Treatment for chronic hepatitis must never be stopped without your specialist's advice.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack.
Several antivirals interact with other medicines — tell your doctor everything you take, including supplements.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Take Olsivir Capsule exactly as prescribed and complete the full course, even if you start feeling better. Consider taking Olsivir Capsule with food to reduce stomach upset. Olsivir Capsule is not a substitute for influenza vaccination, and your doctor may recommend both. Drink plenty of fluids and get adequate rest while recovering from flu symptoms. Small, frequent meals may help if nausea or vomiting occurs while taking Olsivir Capsule. Inform your doctor immediately if you notice unusual mood changes, confusion, agitation, or behavioral changes, especially in children and adolescents. Seek urgent medical help if you have breathing difficulty, a very high fever, severe weakness, confusion, or bluish lips. Wash your hands often, wear a mask if advised, and avoid close contact with others to reduce the spread of flu. Inform your doctor if you are pregnant, breastfeeding, or have kidney disease before taking Olsivir Capsule. Consult your doctor if symptoms worsen or return after initial improvement.
