Antibiotics save lives, but using them carelessly creates resistant bacteria that don’t respond to treatment. The World Health Organization lists antibiotic resistance among the top global health threats — which means it matters how you get and use these drugs.
Antibiotics kill or slow bacteria. Common groups you’ll hear about are penicillins (amoxicillin), cephalosporins, macrolides (azithromycin), fluoroquinolones, and sulfonamides (trimethoprim/sulfamethoxazole). Each group works differently and has different side effects and drug interactions, so treating the right bug with the right drug is key.
Only take antibiotics when a doctor prescribes them for a confirmed or likely bacterial infection. Don’t ask for an antibiotic for a cold or most sore throats — those are usually viral. Take the exact dose at the right times and finish the full course unless your doctor tells you otherwise. Stopping early can leave stubborn bacteria behind and encourage resistance.
Don’t share leftovers or use someone else’s prescription. If you miss a dose, follow the instructions on the label or ask your pharmacist instead of doubling up. Tell your prescriber about allergies, pregnancy, breastfeeding, and other medicines you take — some antibiotics interact with blood thinners, birth control, or supplements.
Buying medication online can be legit and convenient, but scams and unsafe products exist. Use only pharmacies that require a prescription, show clear contact details, and display a pharmacy license or verification. Look for third-party seals like verified pharmacy programs and read recent customer reviews. If a site sells powerful antibiotics without a prescription or offers suspiciously low prices, walk away.
Opt for pharmacies that provide detailed drug information, shipping policies, and responsive customer support. Keep records of what you ordered and check the packaging on arrival — correct labeling, batch numbers, and expiration dates matter. If you’re unsure about a drug you received, compare it with reliable sources or call your local pharmacist before taking it.

Watch for side effects: nausea, diarrhea, rashes, and in rare cases severe allergic reactions. If you develop high fever, bloody diarrhea, breathing trouble, or swelling, stop the drug and get urgent care. Also, if symptoms don’t improve in 48–72 hours after starting therapy, contact your doctor — you may need a different treatment.
If you want a quick checklist: confirm the prescription, verify the pharmacy, check packaging and expiry, follow dosing instructions, and report bad reactions.
