What you should know

Antibiotic medicines treat bacterial infections. They kill bacteria and keep it from growing. If you use antibiotics the wrong way, they can make it difficult for your body to fight disease. Wrong use could lead to:

  • Allergic reaction.
  • Severe infection.
  • Deadly diarrhea.

Bacteria becoming resistant to antibiotics is mostly caused by using too many. One in 3 antibiotic prescriptions is unnecessary.

What you can do

Help fight antibiotic resistance and stop the spread of disease.

  • Wash your hands.
  • Get vaccinated.
  • Take antibiotics exactly as prescribed (don't skip doses or stop early).
  • Don't ask for antibiotics when your doctor says you don't need them.

    Instead, ask your doctor how to ease your symptoms.
