Cephalexin – What It Is, How It Works, and When to Use It

When you see Cephalexin, a broad‑spectrum oral penicillin‑type antibiotic used for skin, ear, and urinary tract infections. Also known as Keflex, it belongs to the penicillin family of antibiotics, which target the bacterial cell wall. This makes it especially effective against bacterial infections, ranging from simple boils to more serious respiratory ailments. Understanding these basics helps you decide if the drug fits your health situation.

Key aspects of Cephalexin use

Cephalexin is a prescription‑only medication, so a doctor’s assessment is the first step. The dosage depends on infection type, severity, and your kidney function. Typical adult regimens run from 250 mg to 1 g every 6–12 hours, while children receive weight‑based dosing. Following the right schedule is crucial because proper dosing reduces the risk of antibiotic resistance. In fact, antibiotic resistance develops when bacteria survive sub‑therapeutic drug levels, leading to treatment failures and harder‑to‑treat infections later on.

Side effects are usually mild—upset stomach, diarrhea, or a rash. Severe reactions like anaphylaxis are rare but can happen, especially if you have a known penicillin allergy. If you notice any swelling, breathing difficulty, or a widespread rash, seek medical help right away. Keep in mind that generic Cephalexin offers the same active ingredient as the brand name but at a lower cost, making it a practical choice for long‑term therapy without sacrificing effectiveness.

Buying Cephalexin online should be done through reputable pharmacies that require a valid prescription. Look for clear contact information, a licensed pharmacist, and secure payment options. Comparing prices across a few trusted sites can save you money, but never sacrifice safety for a discount. Remember, a legitimate online pharmacy will never ask for cash‑only transactions or pressure you to skip the prescription step.
