Antiviral medications such as Tamiflu and Relenza, which are effective in treating the H1N1 swine flu, should be taken only by people hospitalized with the flu or those at high risk for complications from the disease, U.S. health officials said Tuesday.
Those at risk include people with underlying health conditions, such as asthma or diabetes, as well as the very young, the elderly, and pregnant women, officials said.
