Bacterial Infection Treatment: What Works and How to Use It

Got a nasty skin sore, a urinary trouble, or a sore throat that won’t quit? Chances are a bacterial infection is behind it. The good news: most everyday infections respond to a short course of oral antibiotics. Below you’ll find a quick rundown of the most common pills, when they’re useful, and how to take them without hassle.

Common Oral Antibiotics

Doctors often start with a penicillin‑type drug for simple infections, but many patients end up with a cephalosporin. Two popular choices are Cefadroxil (Duricef) and Cephalexin (Keflex). Both belong to the same family, work against a wide range of bacteria, and are taken once or twice daily, which makes them easy to fit into a busy schedule.

Cefadroxil is a good fit for skin infections, ear infections, and some respiratory bugs. It’s usually prescribed at 500 mg twice a day for adults. Cephalexin, on the other hand, shines for urinary tract infections and certain strep throat cases. The typical dose is 250–500 mg every six hours, though doctors may adjust it based on severity.

Both drugs have similar side‑effects: mild stomach upset, a rare rash, and occasional diarrhea. If you notice a severe rash or have difficulty breathing, stop the medicine and call a doctor right away. Otherwise, taking the pill with food can help ease any stomach bother.

How to Use Antibiotics Safely

First rule: finish the full prescription, even if you feel better after a few days. Stopping early can let surviving bacteria grow back stronger, which leads to resistance. If you miss a dose, take it as soon as you remember—unless it’s almost time for the next one. In that case, skip the missed pill; don’t double up.

Second rule: avoid mixing antibiotics with alcohol or certain over‑the‑counter meds without checking. Alcohol doesn’t always make the drug less effective, but it can worsen side‑effects like stomach upset. If you’re on a blood thinner, talk to your pharmacist before starting a cephalosporin.

Third rule: keep an eye on your body. Mild diarrhea is common, but if it’s watery, persistent, or accompanied by fever, you might have a Clostridioides difficile infection—a serious complication that needs medical attention.

Lastly, ask your doctor why a specific antibiotic was chosen. Knowing the target bug helps you understand the treatment length and any follow‑up tests you may need. Some infections, like certain pneumonia strains, require a longer course (often 10‑14 days) to fully clear.

In summary, most bacterial infections can be cleared with a simple oral antibiotic like Cefadroxil or Cephalexin. Pick the right drug, follow the dosage schedule, finish the pack, and watch for unusual symptoms. When in doubt, call your healthcare provider—better safe than sorry.
