Antibiotics: when to take them, when not to

Sick and wondering if you need antibiotics? Many people grab them hoping for a quick fix. But antibiotics only fight bacterial infections, not viruses like colds or most sore throats. Using them when you don’t need them can cause side effects and help bacteria become resistant. That makes future infections harder to treat.

If a doctor prescribes antibiotics, follow the plan: take the dose on time, finish the full course, and don’t save leftovers. Stopping early can leave some bacteria alive and encourage resistance. If you feel worse or have severe side effects—rash, swelling, trouble breathing, high fever—call your provider right away.

Quick safety rules

Here are simple, practical rules you can use today:

• Ask if the infection is bacterial and whether tests (like cultures) are needed.
• Tell your prescriber about allergies and current meds—some antibiotics interact with common drugs.
• Avoid antibiotics for viral infections unless a doctor confirms a secondary bacterial infection.
• Never share prescriptions or use someone else’s antibiotics.
• When buying online, use licensed pharmacies that show pharmacist contact info and require a prescription when needed.

Buying meds online? be cautious. Check pharmacy credentials, read reviews, confirm that a licensed clinician issues prescriptions, and avoid shops offering powerful antibiotics without any prescription. Cheaper is not always safer—fake or low-quality drugs are a real risk.

Want quick help deciding? Start by asking: is this likely bacterial? Do I have a legitimate prescription? Am I allergic to penicillin or sulfa drugs? Getting clear answers to these will steer you toward the right treatment and keep future options working when you need them most.
