What is Tamiflu?

Tamiflu contains Oseltamivir phosphate, a medicine that prevents influenza (the flu virus) from spreading in the body. Taking Oseltamivir to treat the flu will ease or prevent the symptoms of the infection. It may also be used if you have had close contact with someone with the influenza virus to prevent the flu from passing onto you.

How to know if you have the flu

The flu or influenza is an infection caused by a virus. The signs you may have the flu include a sudden fever, muscle aches, fatigue, headaches, and sinus congestion. Generally, what differentiates a common cold from the flu is the flu will occur suddenly and cause muscle pain where colds generally come on slower and don’t give muscle pain.

How does Tamiflu work?

The medicine will attach itself to cells infected and stop the infected cell from being able to release the virus inside. This prevents more cells from becoming infected and lowers the amount of virus inside the body.

How effective is Tamiflu?

If taken within the first 48 hours of the flu, Tamiflu can shorten the severity and duration of the flu by several days. It also lowers the risk of complications such as pneumonia by over 40% and the risk of hospitalisation by over 60%.

Take ONE tablet TWICE daily for 5 days within the first 48 of flu symptoms. For prevention after exposure take ONE tablet daily for 10 days.

Is Tamiflu on the NHS?

Yes, the NHS is able to offer coverage for Tamiflu, however, it comes with a few conditions. The type A or B flu are in circulation, you have certain risk factors, and you see them less than 48 hours after symptoms begin.
