Cephalexin UK – What It Is, How to Use It, and Where to Get It Safely

Cephalexin is a common antibiotic you’ll see prescribed for skin infections, ear infections, urinary tract infections and more. It belongs to the cephalosporin family, which works by stopping bacteria from building cell walls, so the infection can’t grow. In the UK it’s sold under brand names like Keflex and generic tablets, usually 250 mg or 500 mg.

How to Use Cephalexin Correctly

When your doctor gives you Cephalexin, they’ll tell you exactly how many tablets you need each day. For most adults the usual dose is 500 mg every 6–12 hours, depending on how severe the infection is. Kids get a dose based on weight, usually 25‑50 mg per kilogram per day split into two or three doses. It’s key to keep taking the medicine for the full course, even if you feel better after a few days – stopping early can let the infection bounce back.

Take the tablets with a full glass of water. You can eat or not eat, but if your stomach gets upset, a light snack can help. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one – then just skip the missed dose. Don’t double‑up.

Common side effects are mild: a bit of nausea, a loose bowel, or a mild rash. Serious reactions like swelling, trouble breathing, or a severe rash need immediate medical help. If you’re on other meds, let your pharmacist check for interactions – Cephalexin can affect the way some blood thinners and oral contraceptives work.

Buying Cephalexin Safely in the UK

In the UK you need a prescription for Cephalexin, whether you get it from a local pharmacy or an online service. The safest route is to use a registered UK pharmacy that asks for a valid prescription from a qualified prescriber. Look for the pharmacy’s registration number on the website – it should be displayed clearly.

If you’re ordering online, make sure the site uses secure HTTPS, offers a clear privacy policy, and lets you upload your prescription securely. Reputable online pharmacies will often let you speak to a pharmacist for a quick check before they dispense the drug.

Prices can vary, so it’s worth comparing a few pharmacies. Some offer free delivery on orders over a certain amount, which can save you a few pounds. Keep an eye out for hidden fees – a reputable pharmacy will list the total cost before you checkout.

Remember, never buy Cephalexin from unverified sellers or overseas sites that don’t ask for a prescription. Those products may be counterfeit, sub‑potent, or even harmful. If you ever feel unsure about a pharmacy, call the NHS Medicines Helpline for advice.

Bottom line: Cephalexin is a solid choice for many bacterial infections when used correctly. Follow your doctor’s dosing instructions, watch for side effects, and only fill your prescription at a trusted UK pharmacy – online or in‑person. With the right approach, you’ll clear up the infection fast and stay safe.
