Antibiotic resistance
Antibiotic resistance means bacteria no longer respond to drugs that used to kill them. That doesn’t just make a sore throat harder to treat—resistant infections can lead to longer illness, more doctor visits, and stronger medicines with worse side effects. You probably saw headlines about drugs like Levaquin (a fluoroquinolone) and levofloxacin; those stories show how powerful antibiotics are—and why losing them would be a big problem.
What causes it?
Resistance happens when bacteria are exposed to antibiotics and the ones that survive pass on traits that protect them. This comes from a few clear practices: taking antibiotics for viral infections (like colds), stopping a course early, getting antibiotics without proper medical advice, and heavy use of antibiotics in farming. Each time an antibiotic is used unnecessarily, you increase the chance resistant strains will appear.
Some antibiotics are more commonly linked with resistance and strong side effects. For example, our Levaquin guide explains both risks and safer alternatives. And if a doctor can’t use Zithromax for a patient, our Zithromax alternatives piece lists real options clinicians turn to.
What you can do
You have a surprisingly big role in slowing resistance. First, only take antibiotics when a healthcare provider says you need them. Don’t push for antibiotics for viral illnesses. If you are prescribed antibiotics, finish the full course unless your doctor tells you otherwise—stopping early lets some bacteria survive and adapt.
Other practical steps: practice good hand hygiene to avoid spreading infections, stay up to date with vaccines so you don’t need antibiotics in the first place, and don’t share or use leftover antibiotics. If you work with animals or buy meat, look for producers who limit routine antibiotic use.
When you talk with your clinician, ask about tests that confirm bacterial infection and whether an alternative treatment is possible. Our Ventolin vs. Levalbuterol and other medication guides show how choosing the right drug can reduce unnecessary antibiotic use overall by managing conditions without them.
On a bigger scale, stewardship programs in hospitals and clear prescribing rules in clinics make a big difference. They track antibiotic use, switch to narrower drugs when possible, and educate prescribers. You can support these efforts by choosing providers who follow stewardship practices and by asking local clinics what they do to prevent resistance.
