Overview
Omiflu 75mg Capsules contains oseltamivir 75mg, an antiviral medicine belonging to the neuraminidase inhibitor class, used to treat and prevent influenza (flu) caused by influenza A and B viruses.
Oseltamivir works by blocking the neuraminidase enzyme on the surface of the influenza virus, which the virus needs to release newly made copies of itself from infected cells. By blocking this step, oseltamivir slows the spread of the virus within the body, helping to shorten the illness and reduce its severity.
How it Works
Oseltamivir is a prodrug that is converted in the body to its active form, oseltamivir carboxylate, which inhibits the neuraminidase enzyme on the influenza virus surface. This enzyme normally allows new virus particles to break free from infected cells and spread to healthy cells; blocking it limits viral spread within the respiratory tract.
Directions for Use
Swallow Omiflu 75mg Capsules capsules whole with a glass of water, with or without food – taking it with food can help reduce nausea. Complete the full course as prescribed, even if you start to feel better before finishing it, to ensure the treatment is fully effective.
Dosage
For treatment of influenza, the usual adult dose of Omiflu 75mg Capsules is one capsule twice daily for 5 days, started as soon as possible and ideally within 48 hours of symptom onset. For prevention after exposure, a lower once-daily dose and different duration is typically used. Your doctor will confirm the exact dose and duration appropriate for your situation, and dose adjustment may be needed if you have reduced kidney function.
