Antibiotics: Use Them Right, or Lose Them
Antibiotics are one of the most important inventions in the history of medicine — and we're slowly blunting them through overuse. Using antibiotics wisely isn't just about your recovery; it's about keeping these drugs working for everyone. Here's what that means in practice.
They don't work on colds and flu
This is the big one. Antibiotics kill bacteria. Colds, flu, and most sore throats and coughs are caused by viruses, which antibiotics do nothing against. Taking them "just in case" won't speed up a viral illness — it only exposes you to side effects and helps resistance along.
Take exactly as prescribed
If a doctor does prescribe antibiotics, take the full course at the right times, and follow their guidance on whether to finish or stop. Skipping doses or quitting the moment you feel better can leave the hardiest bacteria alive — the ones most likely to come back stronger.
Never share or stockpile them
The leftover antibiotics in your cabinet aren't a backup plan. The right antibiotic depends on the specific bug and the specific person — taking the wrong one (or too little) can make things worse and feed resistance.
Why resistance is everyone's problem
When bacteria evolve to survive our drugs, once-simple infections become hard or impossible to treat. The World Health Organization calls antibiotic resistance one of the biggest threats to global health. Every unnecessary course, anywhere, pushes that problem forward.
Ask the better question
Instead of asking "Can I get antibiotics?", ask "Do I actually need them, or will this clear up on its own?" With UMD ("Use My Doctor"), you can get that judgment from real doctors quickly — so you treat what needs treating, and skip what doesn't.
