Cephalexin: Uses, Dosage, Safety and Buying Tips

When working with Cephalexin, a first‑generation cephalosporin antibiotic used to treat a range of bacterial infections. Also known as Keflex, it attacks the bacterial cell wall and stops growth.

Cephalexin belongs to the larger family of generic antibiotics, which are chemically identical to brand‑name drugs but usually cost less. Most people get these medicines from a reputable online pharmacy, where price‑comparison tools and pharmacy certifications help weed out fakes. Because its main job is to clear bacterial infection, knowing when the drug is appropriate saves you from unnecessary side effects and slows resistance.

Key Things to Know About Cephalexin

Cephalexin is typically prescribed for skin infections, ear infections, throat infections, and uncomplicated urinary‑tract infections. The usual adult dose ranges from 250 mg to 1 g every 6–12 hours, depending on infection severity. Children get a weight‑based dose, often 25–50 mg per kilogram per day split into 2–4 doses. Common side effects include mild stomach upset, diarrhea, and occasional rash. Serious allergic reactions are rare but can happen, especially in people with a penicillin allergy. Antibiotic resistance is a growing concern, and it affects how well Cephalexin works. Overuse or not finishing the prescribed course can give surviving bacteria a chance to adapt. That’s why doctors emphasize completing the full regimen, even if you feel better after a few days. If you notice persistent fever, worsening pain, or new rash, contact your clinician right away – it could signal a resistant strain or an adverse reaction. When you’re ready to purchase, start by checking the pharmacy’s licensing status with Health Canada or the relevant provincial regulator. Look for a physical address, a pharmacist‑visible contact number, and clear privacy policies. Compare prices across at least three sites, but never choose the cheapest option if the pharmacy lacks proper credentials. Make sure the product label matches the dosage and form (tablet, capsule, suspension) you need. Finally, keep a copy of the prescription and the receipt for your records; they’re useful if you need to verify the purchase later.
