Antibiotic vs. Antiviral

An antibiotic is different from an antiviral. Antibiotics fight bacteria; antivirals fight viruses. The flu is a virus, and Tamiflu is an antiviral medicine. It is used to treat the flu (influenza) in people 2 weeks of age and older who have had flu symptoms for no more than 2 days. Tamiflu can also reduce the chance of getting the flu in people 1 year of age and older.

In a study of children 1-12 years old, Tamiflu helped children get better up to 1.5 days (26%) faster compared with children who didn’t take Tamiflu within 48 hours of first symptoms.

Preventive Actions to Fight the Flu

To help prevent the spread of the flu virus, remind your child to wash his or her hands frequently and cough or sneeze into tissues. Wipe surfaces—such as bathroom and kitchen counters, and objects, like your child’s toys—with a household disinfectant.

Taking antiviral Tamiflu may also help prevent the flu in young children. In a study of children 1-12 years old who were exposed to the flu, taking Tamiflu reduced their chance of getting the flu. Learn How to Give Tamiflu to Children
