Take your antibiotics in the right way.
- Take the antibiotic exactly as the doctor prescribes, even if you start to feel better. Do not skip doses or stop taking an antibiotic early unless your doctor tells you to do so.
- Only take antibiotics prescribed for you; do not share or use leftover antibiotics. Antibiotics treat specific types of infections. Taking the wrong medicine may delay treatment and allow bacteria to grow.
- Do not save antibiotics for the next illness or infection. Get rid of any leftover medicine once the prescribed course of treatment is completed.
- Prevent infections, including antibiotic-resistant infections, by practicing good hand hygiene and getting recommended vaccines.
- Do not ask for antibiotics when your doctor thinks you do not need them.
- Remember antibiotics have side effects. When you doctor says you don’t need an antibiotic, taking one may do more harm than good.
Consider alternatives to antibiotic use when you are feeling sick.

Dispose leftover antibiotics appropriately.
- Low levels of antibiotics in the environment might promote development of antibiotic-resistant bacteria. It is important to practice appropriate disposal of unused pharmaceuticals to avoid releasing antibiotics and other drugs into the environment.
For example, one should not flush unused antibiotics down the toilet.

Livestock and agriculture
- Even with good farming practices, animals occasionally need veterinary treatment to stay healthy. Sometimes this includes antibiotics to treat bacterial infection. However, it is critical that antibiotics be used responsibly to prevent the emergence of resistance.

Your pets
- It is also important to use antibiotics responsibly when caring for your pets as misuse in pets can always cause antibiotic resistance.
