Cefaclor: What It Is, How It's Used, and What Alternatives Work Better

When you're dealing with a stubborn ear infection, sinusitis, or a skin infection that won't quit, your doctor might reach for Cefaclor, a second-generation cephalosporin antibiotic used to treat bacterial infections. Also known as Ceclor, it's one of those older but still widely prescribed drugs that works well for common bugs—but not all of them. Unlike broad-spectrum antibiotics that hit everything, Cefaclor targets specific bacteria like Streptococcus and some strains of E. coli, making it a go-to for respiratory and urinary tract infections in adults and kids.

But here’s the thing: Cefaclor isn’t always the best choice. Many doctors now prefer amoxicillin for simple infections because it’s cheaper, gentler on the gut, and just as effective. Or they’ll pick cephalexin, another cephalosporin, if you’re allergic to penicillin. Even azithromycin, a macrolide antibiotic, is often chosen for its once-daily dosing and fewer stomach issues. The truth? Cefaclor has a place, but it’s shrinking. Studies show higher rates of diarrhea and rash compared to newer options, and resistance is creeping up in some areas.

What you’ll find in the posts below isn’t just a list of drug names. It’s a practical breakdown of how antibiotics like Cefaclor stack up against their alternatives—what works, what doesn’t, and what side effects you’re actually likely to deal with. You’ll see comparisons between generic antibiotics, how dosing differs, and why some meds are better for kids or people with allergies. You’ll also find guides on when to avoid antibiotics altogether, how to spot a fake online pharmacy selling fake Cefaclor, and what to do if your infection doesn’t improve after a few days. This isn’t theory. It’s real-world advice from people who’ve been there.
