When you’re prescribed Cefaclor, a second-generation cephalosporin antibiotic used to treat bacterial infections like ear infections, bronchitis, and urinary tract infections. Also known as a cephalosporin antibiotic, it works by stopping bacteria from building strong cell walls, which kills them or keeps them from multiplying. Unlike some broad-spectrum antibiotics, Cefaclor targets specific bacteria, which is why doctors often choose it for common infections—especially when penicillin isn’t an option.
But Cefaclor doesn’t just fight infection. It also shakes up your gut. That’s because antibiotics like Cefaclor don’t just kill bad bacteria—they wipe out good ones too. This disruption can lead to diarrhea, bloating, or even yeast infections. And here’s something you might not expect: research is starting to connect this gut imbalance to changes in mood. Some people report feeling anxious, low, or even depressed after taking Cefaclor. It’s not common, but it’s real. The gut-brain connection isn’t just a buzzword—it’s biology. When your microbiome gets thrown off, your brain can feel it too. That’s why some doctors now ask patients about mental health changes after antibiotic use, not just stomach issues.
Cefaclor is often compared to other antibiotics like amoxicillin or cephalexin. It’s stronger than the first-gen ones, but not as powerful as later cephalosporins like ceftriaxone. It’s taken by mouth, usually two or three times a day, and works best when taken on an empty stomach. But if it upsets your stomach, eating a light snack first helps. It’s not for viral infections like colds or flu—no matter how bad you feel. Misusing it leads to resistance, and that’s a growing global problem. If you’ve had allergic reactions to penicillin, you might still react to Cefaclor, so always tell your doctor your full history.
What you’ll find below are real, practical guides about Cefaclor and what happens when you take it. Some posts dig into how it affects your mental health. Others explain how it interacts with your gut bacteria. You’ll also see how it stacks up against other antibiotics, what side effects to watch for, and what to do if things don’t go as planned. This isn’t just a list of articles—it’s a toolkit for understanding what Cefaclor really does to your body, beyond the prescription label.
Cefaclor is an oral antibiotic used for mild skin and soft tissue infections like cellulitis and post-drainage wounds. It's effective against common bacteria but not MRSA or Pseudomonas. Proper use requires matching the infection type and avoiding unnecessary use.
