Antibiotics

Antibiotics have saved countless lives, but using them wrong fuels resistance and side effects. If you want real help, not panic, this page gives plain, useful facts: how antibiotics work, which ones are common, and practical steps to stay safe.

How antibiotics work and the main types

Antibiotics kill or stop bacteria from growing. They don’t touch viruses, so they won’t help with colds or most sore throats. Families of antibiotics matter because each targets different bugs. For example, cephalexin is a cephalosporin often used for skin and ear infections. Macrolides (like azithromycin) work well for respiratory infections. Clindamycin treats certain staph and anaerobic infections. Fluoroquinolones (like ciprofloxacin) are powerful but carry risks such as tendon problems and nerve issues, so doctors reserve them for specific cases.

When an infection won’t clear or tests show resistance, your doctor may switch drugs. That’s why culture and sensitivity testing is useful: it tells you which antibiotic will actually work.

Practical safety tips you can use today

Always follow the prescription. Finish the course unless your doctor says stop. Don’t save leftovers for later or share antibiotics with someone else. If you have allergies, tell your provider—penicillin and cephalosporin cross-reactivity can matter for some people.

Watch for serious reactions: hives, swelling, breathing trouble, or high fever. If those happen, seek emergency care. For less severe side effects like nausea or diarrhea, check with your prescriber; sometimes switching drug or adjusting dose helps.

Certain antibiotics interact with common medicines. For example, rifampin lowers hormonal contraceptive levels. Some antibiotics can interfere with blood thinners. If you take other meds, list them for your pharmacist and doctor before starting treatment.

Pregnancy and kids need special attention. Some drugs are off-limits in pregnancy or for young children. If you’re pregnant, breastfeeding, or treating a child, ask for options known to be safe in those situations.

Antibiotic resistance is real. Use antibiotics only when needed. Your doctor may suggest testing, delaying treatment, or using narrower-spectrum drugs that target the specific bacteria rather than broad-spectrum agents that kill many types.
