Cefadroxil – Everything You Need to Know

When working with Cefadroxil, a first‑generation oral cephalosporin antibiotic used to treat a variety of bacterial infections. Also known as Keflex, it stops bacteria by weakening their cell walls, which halts the spread of infection.

Key Facts About Cefadroxil

The Cephalosporins, a broad class of beta‑lactam antibiotics include drugs like cefalexin, cefuroxime and ceftriaxone. Cefadroxil belongs to the first‑generation subgroup, which means it’s especially good against gram‑positive bacteria such as Staphylococcus aureus and Streptococcus pyogenes. Because of its oral form, doctors often pick it for skin infections, uncomplicated urinary tract infections and throat infections where a quick, effective option is needed.

Patients wonder which infections actually respond to bacterial infections, conditions caused by harmful bacteria that invade body tissues. Cefadroxil’s spectrum covers cellulitis, erysipelas, pharyngitis, and certain respiratory tract infections. It’s less potent against gram‑negative organisms, so doctors will choose a different antibiotic if they suspect Pseudomonas or resistant Enterobacteriaceae. Knowing the target bugs helps avoid unnecessary prescriptions and keeps treatment focused.

Getting the dose right is crucial. The dosage guidelines, recommended amounts based on age, weight, kidney function and infection severity for adults usually range from 250 mg to 1 g taken every 12 hours. Children get weight‑based dosing, often 30 mg/kg/day divided twice daily. Taking the medicine with food can reduce stomach upset, but missing a dose shouldn’t be made up by doubling the next one. Proper dosing minimizes the chance of treatment failure and helps keep resistance in check.

Speaking of resistance, antibiotic resistance, the ability of bacteria to survive despite drug exposure is a growing concern. Overuse or underuse of Cefadroxil can push bacteria to develop beta‑lactamase enzymes that break down the drug. To combat this, clinicians often reserve Cefadroxil for infections proven or strongly suspected to be susceptible, and they may switch to alternatives like amoxicillin, clindamycin or a second‑generation cephalosporin if cultures show resistance. Patients can help by completing the full course and not sharing leftovers with others.
