Before you start any treatment, you should read the manufacturers leaflet contained with the medication. This has further information and lists all the potential side effects.
Tamiflu (Oseltamivir) is used to treat influenza type A and B viruses. It prevents the virus from spreading in your body, reducing the severity of your symptoms and complications.
If you are taking it for prevention, that is, you have been in contact with someone who has the flu but you do not have symptoms yourself then take one capsule a day for ten days.
If you already have flu symptoms and are taking it for treatment then take one capsule twice a day for five days. It should be started within 48 hours from when your symptoms start. The sooner it is started, the more effective it is.
Swallow the capsules with a drink of water. You can take your doses either before or after meals, however, taking the doses after food can often reduce the risk of nausea.
Keep taking the Tamiflu until the full course is finished (unless a doctor tells you to stop), even if you feel the infection has cleared up, as it may return. If you forget to take a dose, take one as soon as you remember unless it's nearly time for your next dose. In this case, just leave out the missed dose and take your next dose as normal.
Never give your medication to other people even if their condition appears to be the same as yours.
