WARNING: Antibiotics don’t work for viruses like colds and the flu.
Using them for viruses will not make you feel better or get back to work faster.
Antibiotics are strong medicines. Keep them that way. Prevent antibiotic resistance.
Antibiotics don’t fight viruses – they fight bacteria. Using antibiotics for viruses can put you at risk of getting a bacterial infection that is resistant to antibiotic treatment. Talk to your doctor or other healthcare provider about antibiotics, visit www.cdc.gov/getsmart, or call 800-CDC-INFO (800-232-4636) to learn more.
Taking antibiotics for viral infections such as a cold, a cough, or the flu will NOT:
Cure the infection
Keep other people from catching it
Help you feel better
