If you feel that you’re coming down with flu, then quick action and some simple measures could make all the difference
If you are beginning to show flu symptoms, you can ask your doctor about prescription antiviral drugs such as oseltamivir (sold as Tamiflu) and zanamivir (Relenza). Both work by blocking an enzyme that helps the virus infect new cells. These drugs are most effective if you take them within 48 hours of your first symptoms and can shorten your bout of flu by a day, although the risk of side-effects mean they will not always be prescribed. It is particularly important to request antivirals if you have a condition such as diabetes or heart disease that increases the risk of complications.
