Tamiflu works best when started within 48 hours of your symptoms beginning.

Preventive treatment needs to start within 48 hours of your last close contact with someone who has flu.

Tamiflu is licensed to start within 48 hours of symptoms. Starting it later is outside the licence but can still help people at higher risk from flu. Our prescriber will check it is suitable for you.

A prescriber will decide whether treatment is right for the patient and may contact me or the patient by SMS, email or phone if more information is needed.
