7. If I get the flu, I’ll take antibiotics to cure it
Seasonal influenza cannot be treated or cured with antibiotic medications. “Antibiotics target bacteria only. Because the influenza illness is from a virus [and not bacteria], antibiotics don’t work,” says Dr. Kerr. Doctors occasionally prescribe antiviral medications such as Tamiflu to help reduce influenza symptoms, but these drugs must be taken in the first few days of the flu, otherwise they don’t offer much symptom relief. “If you think you have influenza-type symptoms it’s best to get seen by your doctor early so we can give you this antiviral medication,” he says.
