Antibiotic Prescription: When You Really Need One
Think antibiotics fix every infection? Not true. Antibiotics only kill bacteria, not viruses, so prescribing them for colds or most sore throats often does more harm than good. This page helps you spot when an antibiotic prescription makes sense, how doctors choose the right drug, and what you can do to use antibiotics safely.
When a prescription is justified
If your symptoms point to a bacterial infection—high fever, worsening symptoms after a few days, thick yellow-green discharge, or a confirmed lab test—an antibiotic may be needed. For example, strep throat, certain ear infections in young kids, urinary tract infections, and bacterial pneumonia commonly require antibiotics. If your doctor says "watchful waiting" or prescribes fluids and rest, that often means your body can beat the infection without antibiotics.
Don’t pressure your clinician for a prescription. If they recommend testing (rapid strep, urine dip, or cultures), that helps avoid unnecessary antibiotics and finds the right medicine when needed.
How doctors pick and what you should ask
Prescribers choose antibiotics based on the likely bacteria, allergy history, age, kidney function, and local resistance patterns. Sometimes they start a broad drug, then switch once test results arrive. Ask three simple questions before you leave: Why this antibiotic? How long should I take it? What side effects or interactions should I watch for? If they can’t answer clearly, ask for a follow-up or clarification from the pharmacist.
Follow the dose and duration exactly. Skipping doses or stopping early can let bacteria survive and become resistant. If side effects appear—high fever, rash, swelling, severe diarrhea, or breathing trouble—stop the drug and contact your provider right away. Tell your prescriber about past allergic reactions, especially hives, swelling, or anaphylaxis; that changes drug choice fast.
Use antibiotics responsibly at home. Finish the full course unless told otherwise, store meds in a cool, dry place, and never share leftover pills with someone else. If you get a prescription and start feeling better after a day or two, still finish the course unless your clinician tells you to stop. For kids, measure liquid doses carefully—use the syringe or cup that came with the medicine.
Want to avoid needing antibiotics? Get vaccinated (flu, pneumococcal), wash hands, and treat minor symptoms early. When you need one, telehealth can be convenient, but make sure the provider asks detailed questions or orders tests when appropriate. Pharmacists are a great second check if you have concerns about interactions or side effects.
Antibiotics save lives when used right. Use them only when necessary, ask clear questions, watch for side effects, and finish the course. That approach keeps you safer and helps slow antibiotic resistance for everyone.
