» What you will be asked to do if you agree to participate
- You will be given study drug and placebo for 5 days, but this might continue for up to 10 days depending on your health. If your doctor feels you are not improving on the study drug, he can put you into another group where you will be treated with a predetermined dose of zanamivir for 5 days, so some people may have up to 14 days of treatment
- You will need to get tests, and we will record any changes in your health and medicines. If you remain in hospital for the entire study, all of the tests and follow-ups will be done during your stay. If you are well enough to go home while taking part in the study, we will telephone you regularly to check your health, and to see if you are taking any new medicines. Depending on when you go home, you may need to come back to the hospital for one or two follow-up visits, and at the end of the study for final tests.
