Tamiflu (Tam-ih-flew) is prescribed by doctors for the treatment of the influenza virus in people who have had symptoms for two days or less. It is a neuraminidase inhibitor that attacks the influenza virus and keeps it from spreading inside the body. It attacks the virus that causes the flu, instead of simply masking symptoms.  

Uses of Tamiflu

Tamiflu (oseltamivir phosphate) is given as a treatment for the flu or to prevent the spread of the flu. Family members or friends who have been directly exposed to the flu virus may be given Tamiflu to decrease the chances of contracting the virus.

Tamiflu Directions

Take Tamiflu by mouth as your doctor directs. Tamiflu can be taken with food if stomach upset occurs. Take Tamiflu immediately when flu symptoms begin or within 48 hours of exposure. People who have already contracted the flu should take Tamiflu twice daily for five days. When taken for prevention purposes, Tamiflu is given once daily for seven days. Tamiflu should be taken at the same time each day. Do not stop using Tamiflu before your doctor tells you too. Talk to your doctor if flu symptoms get worse or new symptoms begin.

Tamiflu Side Effects

Some side effects may occur. Talk to your doctor about extreme cases of nausea. You should also talk to the doctor if you experience vomiting, persistant dizziness, cough, or weakness, sore throat, or fever.

Tamiflu Precautions

Tamiflu is not effective for treating illnesses other than the influenza virus. Many kinds of viruses can cause flu like symptoms, so see a doctor for testing to determine if you truly have the influenza virus that can be effectively treated with Tamiflu. Consult your doctor if Tamiflu does not help alleviate flu symptoms or if symptoms worsen during treatment.
