Tamiflu, also medically known as oseltamivir, is an antiviral agent used to treat the flu in patients who have experienced symptoms for no more than two days. Tamiflu should not be given to infants who are less than a year old.

Tamiflu works by stopping the growth and spread of certain types of flu viruses in the body. It is taken orally in the form of tablets and is usually taken twice a day for approximately five days or as prescribed by your doctor.

Common side effects associated with this medication include upset stomach, vomiting, difficulty sleeping and dizziness. If the side effects appear to be getting progressively worse, contact your doctor immediately for assistance.

Tamiflu may occasionally be prescribed for other purposes as well, as directed by your doctor.
