Tamiflu

What is Tamiflu?

Tamiflu is an anti-viral medication used to treat or prevent flu (the influenza virus). Tamiflu is currently the only licensed medication that has been clinically proven to reduce the duration of a flu outbreak.

How Effective is Tamiflu

Tamiflu has been clinically proven to reduce the duration of flu by up to 30% compared to people who don’t take Tamiflu in the first 48 hours. You should take Tamiflu as soon as possible for the maximum effect.

How does Tamiflu Work?

Tamiflu belongs to a group of medicines known as neuraminidase inhibitors. Tamiflu blocks the effects of a chemical called neuraminidase that is created by the influenza virus. As the flu virus needs neuraminidase to spread in the airways. By blocking the effects of neuraminidase, Tamiflu reduces the spread of the influenza virus in the airways. This makes it easier for the body’s immune system to clear up the infection.

When Should I take Tamiflu

Tamiflu can be taken to treat a current outbreak of flu if you start taking within 48 hours of flu symptoms appearing. Alternatively Tamiflu can be taken to prevent the flu if you have been in contact with someone with the flu or for up to six weeks as seasonal protection.

How to Take Tamiflu

To treat a current outbreak: The recommended oral dose is one tablet of Tamiflu (75mg) twice daily for 5 days for adolescents (13 to 17 years of age) and adults.

To prevent catching the flu from someone who is infected: The recommended dose for prevention of influenza following close contact with an infected individual is one tablet (75mg) daily for 10 days
