Oseltamivir is used to treat symptoms caused by the flu virus (influenza). It helps make the symptoms (e.g., stuffy nose, cough, sore throat, fever/chills, aches, tiredness) less severe and shortens the recovery time by 1-2 days. This medication is also used to prevent the flu if you have been exposed to someone who already has the flu (e.g., sick household member). This medication works by stopping the flu virus from growing. It is not a substitute for the flu vaccine. (See Notes)
Nausea and vomiting may occur as your body adjusts to this medication and usually go away after 1-2 days. Dizziness may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. The flu itself or oseltamivir may rarely cause serious mental/mood changes. This may be more likely in children.

Seek immediate medical attention if this rare but very serious side effect occurs: chest pain. A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
