How Can I Protect my Family and Myself From Antibiotic Resistance?

There is a way to protect yourself and others from resistant bacteria, and that is to respect antibiotics and take them only when necessary for a bacterial infection. Here are some useful tips:

When you see a doctor, don't demand antibiotics. Understand that antibiotics are used for bacterial infections, not symptoms of a cold or flu virus.

If a doctor prescribes antibiotics, use them as prescribed. Take all of the antibiotics as directed and don't save some for future use.

Don't share antibiotics with others.
