Amoxicillin: What It Is and How to Use It

Amoxicillin is one of the most common antibiotics you’ll hear about. Doctors prescribe it for ear infections, strep throat, sinus problems, and a few skin infections. It works by stopping bacteria from building the walls they need to survive, so the infection clears up faster.

Typical adult doses range from 250 mg to 875 mg taken every 8‑12 hours, depending on the infection and how severe it is. Kids get a dose based on weight, usually about 20‑45 mg per kilogram per day split into two or three doses. Always follow the exact amount your doctor writes on the label – the right dose helps the medicine work and cuts down the chance of resistance.

When to Take Amoxicillin

You’ll only need amoxicillin if a doctor says you have a bacterial infection that responds to it. It won’t help with viral bugs like the common cold or flu. Take the pills with a full glass of water, and you can have them with food or on an empty stomach – just be consistent, so your blood level stays steady.

If you’re prescribed a 10‑day course, finish all of it even if you feel better after a few days. Stopping early can let some bacteria survive and become harder to treat later.

Common Side Effects and Safety Tips

Most people tolerate amoxicillin well. The most common side effects are mild stomach upset, diarrhea, or a rash. If you get a rash that looks like hives, feels itchy, or you notice swelling of the face or tongue, stop the medicine right away and call a doctor – those could be signs of an allergy.

Other things to watch for: severe diarrhea that looks watery or contains blood, or a fever that comes back after a few days of feeling better. Those could mean a new infection or a complication, so get medical advice quickly.

Amoxicillin can interact with some other meds, especially certain blood thinners and oral contraceptives. Tell your pharmacist or doctor about every prescription and over‑the‑counter product you’re using.

Store the tablets at room temperature, away from moisture and heat. If you have liquid amoxicillin, keep it in the fridge once opened and discard any leftover after the date on the bottle – it can lose potency.

If you miss a dose, take it as soon as you remember, unless it’s almost time for your next one. In that case, skip the missed dose and keep your normal schedule. Don’t double‑up because that can raise the risk of side effects.

Call your doctor if you notice any new symptoms, if the infection isn’t getting better after a few days, or if you have any concerns about using the drug while pregnant or nursing. Your healthcare provider can adjust the dose or switch you to a different antibiotic if needed.

Bottom line: amoxicillin is a trusted, effective option for many bacterial infections when you use it exactly as prescribed. Stick to the schedule, watch for side effects, and keep an eye on how you feel – that way you’ll get back to normal faster and avoid surprises later on.
