Cefadroxil: What it is and when it's used
Ever been handed a small white pill and told it’ll clear an infection in days? That could be cefadroxil. It’s a first‑generation cephalosporin antibiotic you take by mouth. Doctors often prescribe it for uncomplicated skin infections, throat infections, ear infections, and some urinary tract infections. It’s a straightforward drug when used the right way.
Cefadroxil works by weakening the bacterial cell wall so bacteria can’t survive. It only treats bacterial infections—no effect on viruses like colds or the flu. That’s why a proper diagnosis matters before starting it.
Quick dosing guide
Dosing depends on the infection and your health. A common adult dose is 500 mg every 12 hours or 1 g once daily, but some infections need different lengths or strengths. Kids get doses based on weight. Always follow your prescriber’s directions—don’t copy someone else’s dose. Typical courses last from 5 to 14 days depending on the problem; stopping early can let the infection return.
Smart safety tips
Side effects are usually mild. Expect possible stomach upset, diarrhea, or a rash. If you get severe diarrhea, high fever, or a rash with blisters, contact a doctor right away—those can be signs of a serious reaction. If you’ve had a severe allergic reaction to penicillin, tell your provider: there’s a chance of cross‑reactivity, and they may choose a different antibiotic.
People with reduced kidney function need lower doses. If you take other drugs, mention them—probenecid can raise cefadroxil levels, for example. There’s mixed evidence about antibiotics lowering birth control effectiveness; using a backup method during treatment is a low‑risk choice if you’re worried.
Practical tips: take cefadroxil at the same times each day to keep levels steady. Taking it with food can reduce stomach upset. Finish the full course unless your doctor tells you otherwise—even if you feel better after a couple of days.
Thinking of buying cefadroxil online? Use licensed pharmacies and expect to provide a valid prescription. Avoid sketchy sites offering antibiotics without a prescription—those pills can be fake, unsafe, or the wrong dose.
Short on time? If you miss a dose, take it as soon as you remember unless the next dose is close. Don’t double up to catch up. Pregnant or breastfeeding? Talk to your doctor—cefadroxil is sometimes used but your provider will weigh risks and benefits.
Questions about interactions, dosing for kids, or whether cefadroxil is right for you? Ask your healthcare provider or pharmacist. They can match the drug to the infection and your health history so you get better safely and quickly.
