If your doctor mentioned Keflex, you’re probably looking at a short course of antibiotics that fights skin infections, ear infections, and even some urinary‑tract bugs. It’s the brand name for cephalexin, a first‑generation cephalosporin. In plain terms, it works like a shield against bacteria that can cause painful swelling or fever.
Most people take Keflex as a tablet, but there are liquid versions for kids or anyone who has trouble swallowing pills. The typical adult dose ranges from 250 mg to 1 g every six hours, depending on how bad the infection is. Your doctor will decide the exact amount based on your weight, age, and what’s infected.
How Keflex Works & When It’s Prescribed
Keflex attacks the bacterial cell wall, making it burst open and die. Because it targets a part of bacteria that humans don’t have, side effects are usually mild. Doctors often prescribe it for:
Skin infections like cellulitis or impetigo.
Bone infections (osteomyelitis) when caught early.
Ear infections (otitis media) in kids.
Urinary‑tract infections caused by susceptible bacteria.
Dental abscesses after a tooth extraction.
If you’re unsure why you got the prescription, ask your pharmacist or doctor. Knowing the exact reason helps you stick to the right schedule and finish the whole course—even if you feel better after a couple of days.
Safe Buying & Dosage Tips
Buying Keflex online can be convenient, but only use reputable pharmacies that require a prescription. Look for sites with clear contact info, pharmacy licenses, and good reviews. Avoid any place that lets you skip the prescription step—those are often scams.
When you get your medication:
Check the label: make sure it says “cephalexin” or “Keflex,” dosage strength, and expiration date.
Take it with a full glass of water. Food isn’t required, but if you experience stomach upset, take it with meals.
Set reminders so you don’t miss a dose—six‑hour intervals keep blood levels steady.
If you miss one, take it as soon as you remember unless it’s almost time for the next dose. Don’t double up.
Common side effects include mild nausea, diarrhea, or a rash. If you notice severe itching, swelling, or trouble breathing, stop taking it and call emergency services right away—that could be an allergic reaction.
For kids, the liquid form is measured with a proper syringe or dosing cup. The dose is usually calculated by weight (mg per kilogram). Never guess; ask your pharmacist for exact instructions.
Finally, store Keflex at room temperature, away from direct sunlight and moisture. Keep it out of reach of children.
With the right dosage, a reputable source, and an eye on side effects, Keflex can clear up many common infections quickly. If you have any doubts, your healthcare provider is the best person to clarify before you start or finish the course.
