Cefaclor: What It Is, How to Use It, and What to Watch For

If you’ve been prescribed a pill called cefaclor, you might wonder what it does and whether it’s safe. Cefaclor is a second‑generation cephalosporin antibiotic, meaning it fights bacteria that cause infections like sinusitis, bronchitis, ear infections, and skin wounds. It works by stopping bacteria from building their cell walls, which kills them fast.

Typical Dosage and How to Take It

Doctors usually give cefaclor in doses of 250 mg to 1 g, taken every 8 to 12 hours. The exact amount depends on the infection’s severity and your kidney function. Swallow the tablets whole with a full glass of water. If you have a stomach upset, you can take it with food, but don’t crush or chew the tablets unless your doctor says it’s okay.

Common Side Effects and Safety Tips

Most people feel fine, but some may notice mild issues like nausea, diarrhea, or a rash. Rarely, cefaclor can cause a serious allergic reaction—look for swelling, trouble breathing, or hives and seek medical help right away. Always tell your doctor about any other meds you’re using, especially blood thinners or other antibiotics, because interactions can happen.

Because cefaclor is cleared by the kidneys, people with kidney problems may need a lower dose. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one. Don’t double up; just continue with your regular schedule.

Finish the whole prescription even if you feel better. Stopping early can let bacteria survive and become resistant, making future infections harder to treat.

Remember, antibiotics only work against bacterial infections, not viral illnesses like the common cold. Using cefaclor when it’s not needed won’t help you feel better and can contribute to resistance.

If you have any doubts—like whether a symptom is an allergic reaction or a normal side effect—call your healthcare provider right away. They can decide if you need to switch medicines or adjust the dose.

Bottom line: cefaclor is a reliable antibiotic when used correctly. Follow the dosing schedule, watch for side effects, and complete the full course. Doing so helps you recover faster and keeps your bacteria from learning how to dodge antibiotics in the future.
