Keflex (Cefalexin)

Cefalexin works by binding to penicillin‑binding proteins on bacterial cell walls, inhibiting the cross‑linking of peptidoglycan strands. This disruption weakens the cell wall, causing osmotic instability and ultimately leading to bacterial cell death.

The dosage of Keflex is determined by the prescribing clinician based on the type and severity of infection, patient age, weight and renal function. Healthcare professionals tailor the regimen to achieve optimal therapeutic outcomes.

Safety data for cefalexin in pregnancy are limited, and the drug is classified as pregnancy category unknown. It should only be used when the potential benefit justifies any possible risk to the fetus. Breastfeeding mothers should consult a healthcare provider, as small amounts may be excreted in milk.

GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Compared with penicillins, cefalexin offers a broader spectrum against certain Gram‑positive organisms and better resistance to β‑lactamase enzymes. It is often chosen when patients have mild penicillin allergies or when the infecting organism is known to be susceptible to cephalosporins.

Keflex tablets should be stored at ambient temperature, below 25 °C, in their original container to protect from moisture. Keep the product out of reach of children and avoid exposure to direct sunlight or excessive humidity.

Keflex is administered orally, typically as a tablet taken with or without food as directed by a healthcare professional. The exact timing and frequency depend on the prescribed regimen and the specific infection being treated.

Serious risks include severe allergic reactions such as anaphylaxis, Clostridioides difficile‑associated colitis, and rare hematologic events like hemolytic anemia. Patients should seek immediate medical attention if they experience symptoms such as difficulty breathing, severe diarrhea, or unexplained fatigue.

Keflex should be avoided in individuals with a known hypersensitivity to cefalexin, other cephalosporins, or penicillins. Caution is also advised for patients with significant renal impairment, as dose adjustment may be required.
