When handling Cephalexin, a first‑generation oral cephalosporin antibiotic used to treat many bacterial infections. Also known as Keflex, it works by stopping bacteria from building cell walls.
Cephalexin belongs to the broader group of antibiotics, drugs that kill or inhibit bacterial growth. Knowing the type of bacterial infection, the illness caused by harmful bacteria such as strep throat, skin cellulitis, or urinary tract infection helps you pick the right dosage and duration. The right dosage how to give cephalexin hinges on the infection’s severity and the patient’s age, weight, and kidney function.
First, Dosage regimen, the schedule and amount of medication taken each day is usually expressed in milligrams per kilogram for kids and a fixed milligram range for adults. A common adult dose is 250‑500 mg every 6 hours, while pediatric dosing often follows 25‑50 mg/kg/day divided into three or four doses. Calculating the exact number avoids under‑treatment, which can let bacteria survive and become resistant.
Second, Pediatric dosing, the specific amount given to children based on weight requires a reliable scale and a calculator or dosing chart. For a 20‑kg child, a typical prescription might be 500 mg total per day, split into three doses of about 166 mg each. Using a liquid formulation makes it easier to measure small amounts accurately.
Third, watch for side effects, unwanted reactions such as diarrhea, nausea, rash, or allergic symptoms. Most are mild, but severe reactions like hives or difficulty breathing need immediate medical attention. Educating the patient or caregiver about these signs can prevent complications.
Finally, remember that adherence, taking the medication exactly as prescribed is crucial. Skipping doses or stopping early can let the infection return and increase resistance risk. Setting alarms or using a medication diary boosts consistency.
Putting these pieces together, you’ll see that giving cephalexin safely means matching the right drug to the right infection, calculating the proper dosage for the person’s weight, monitoring for side effects, and sticking to the prescribed schedule.
