What Experts Say
Cephalexin is a first generation cephalosporin antibiotic. It works by binding to penicillin binding proteins on the bacterial cell wall, blocking the final step of cell wall synthesis. This action is bactericidal, so it kills susceptible bacteria rather than only slowing their growth.
The drug is active against many gram positive organisms, including Streptococcus and methicillin sensitive Staphylococcus aureus, along with some gram negative bacteria such as E. coli and Klebsiella. It does not cover methicillin resistant Staphylococcus aureus or Pseudomonas, so sensitivity testing guides therapy in resistant infections.
Cephalexin is well absorbed orally and reaches peak blood levels within about an hour. It is cleared largely unchanged through the kidneys, so consistent dosing intervals matter. Completing the full course, even after symptoms improve, helps clear the infection fully and limits antibiotic resistance.

How to use Keflex Capsule 250mg?
- Take Keflex Capsule 250mg by mouth with or without food, as advised by the doctor.
- Swallow the capsule whole with a full glass of water.
- Take doses at evenly spaced intervals, usually every 6 hours, to keep a steady level in the body.
- Complete the full course even if symptoms improve early, since stopping early can lead to antibiotic resistance.
- Do not double the dose to make up for a missed one, take it as soon as remembered unless the next dose is near.
Drug Interactions
- Metformin: Cephalexin can raise metformin blood levels, so blood sugar should be monitored closely.
- Probenecid: This gout medicine slows the elimination of Cephalexin, which can raise its blood levels and side effect risk.
- Warfarin: Cephalexin may enhance the blood thinning effect, so clotting levels should be checked more often.
- Live Bacterial Vaccines: Antibiotics like Cephalexin can reduce the effectiveness of live vaccines such as the typhoid vaccine.
- Other Antibiotics: Combining Cephalexin with other antibiotics should only be done under medical supervision to avoid reduced effectiveness or added side effects.
Risks and warnings
- Penicillin Allergy: People with a history of severe penicillin allergy should use Keflex Capsule 250mg with caution, since cross reactivity with cephalosporins can occur.
- Kidney Impairment: Patients with reduced kidney function need a lower dose, since Cephalexin is cleared through the kidneys.
- Clostridioides Difficile Diarrhea: Prolonged or repeated antibiotic use can trigger severe diarrhea caused by bacterial overgrowth, even weeks after stopping the medicine.
- Pregnancy And Breastfeeding: Keflex Capsule 250mg is generally considered safe in pregnancy and breastfeeding, but a doctor should confirm the correct dose first.
- Seizure Disorder: People with a history of seizures should be monitored closely, since high doses of Cephalexin have rarely been linked to convulsions.
