Uses of Tamiflu

Tamiflu (oseltamivir phosphate) is a medication used to treat some types of influenza and illness caused by the flu viruses (influenza). Oseltamivir is also used to prevent the flu for those who are exposed, such as the family members of the patient, thus helping to reduce the chance of getting the flu when there is a flu outbreak in the community.

Tamiflu Directions

Take Tamiflu orally as directed by your doctor. You may take Tamiflu with food or milk to minimize stomach upset. Take Tamiflu as soon as flu symptoms appear or as soon as possible after you have been exposed, possibly within 48 hours. If you came down with the flu, take Tamiflu twice a day for 5 days: once in the morning and once in the evening, completing the entire 10 doses. To prevent the flu, take Tamiflu once a day for at least 7 days or take it exactly as prescribed by your doctor. Tamiflu works best if it is kept at a constant level in your body. Therefore, try to take Tamiflu at a fixed time each day. Stopping Tamiflu too early may result in a relapse of the infection. Inform your doctor if your condition worsens or if new symptoms appear.

Tamiflu Side Effects

If nausea occurs, persists, or worsens, tell your doctor as soon as possible. Notify your doctor immediately if you have any of these rare but serious side effects: dizziness, vomiting, persistent cough, persistent weakness, fever, or sore throat.

Tamiflu Precautions

Tamiflu has not been shown to treat flu-like illnesses caused by any virus other than influenza A and B. Thus, it will not treat stomach flu, common cold, or other respiratory illnesses, which are not caused by influenza viruses. There are many types of viruses that cause symptoms that are not easy to distinguish from flu. Contact your health care provider if you feel worse or develop new symptoms during or after treatment, or if your influenza symptoms do not improve after taking Tamiflu.
