Keflex (Cefalexin)

Cefalexin belongs to the first‑generation cephalosporin class. It binds to penicillin‑binding proteins on the bacterial cell wall, blocking the final step of peptidoglycan cross‑linking. This inhibition weakens the cell wall, causing bacterial lysis and death, particularly against Gram‑positive organisms and some Gram‑negative bacteria.

The dosage of Keflex is individualized by the prescribing clinician based on the type and severity of infection, patient age, weight, and renal function. Typical adult regimens range from 250 mg to 1 g taken two to four times daily, but exact dosing must be confirmed by a healthcare professional.

Safety data for cefalexin in pregnancy and lactation are limited. It should be used only when the potential benefit to the mother outweighs any possible risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss the risks and alternatives with their doctor.

Both Keflex (cefalexin) and amoxicillin are oral beta‑lactam antibiotics, but they belong to different classes—cephalosporin versus penicillin. Cefalexin has stronger activity against certain Gram‑positive organisms and is less affected by beta‑lactamase enzymes, while amoxicillin offers broader coverage of some Gram‑negative bacteria. Choice depends on the suspected pathogen, resistance patterns and patient tolerance.

Keflex tablets should be stored at room temperature, below 25 °C, in their original packaging to protect them from moisture and light. Keep the container tightly closed and out of reach of children. Do not store in bathrooms or near heat sources.

Keflex is taken orally, usually as a tablet swallowed whole with a full glass of water. It can be taken with or without food; however, taking it with food may reduce stomach upset. The exact frequency and duration are determined by the prescribing clinician.

Serious adverse reactions include severe allergic responses such as anaphylaxis, skin conditions like Stevens‑Johnson syndrome, and Clostridioides difficile‑associated colitis. Patients should seek immediate medical attention if they experience difficulty breathing, swelling of the face or throat, widespread rash, persistent diarrhea, or signs of liver dysfunction.

Keflex should be avoided in individuals with a known hypersensitivity to cefalexin, other cephalosporins, or penicillins. Patients with severe renal impairment may require dose adjustment, and those with a history of severe allergic reactions should not use the drug without careful medical supervision.
