Amoxicillin – Simple Guide to Uses, Dosage & Safety

If you’ve been prescribed a white pill called amoxicillin, you’re probably wondering what it actually does and how to use it right. This page breaks down the basics in plain English so you can feel confident taking it.

When to Use Amoxicillin

Amoxicillin belongs to the penicillin family and works by stopping bacteria from building their cell walls. The result is that the bugs die off and the infection clears up. Doctors usually pick it for ear infections, sinusitis, throat infections like strep, some types of pneumonia, and urinary tract infections. It’s also used for certain skin infections and dental procedures that need extra protection.

How to Take Amoxicillin Safely

For adults, the standard dose is 500 mg every 8 hours or 875 mg every 12 hours, depending on the infection’s severity. Most courses last 7‑10 days, but follow your doctor’s instructions exactly. Kids get a dose based on weight—usually 20‑40 mg per kilogram per day, split into two or three doses.

Take the pill with a full glass of water. You can swallow it with or without food; a meal may help reduce stomach upset. If you’re using the liquid form, shake the bottle well and use the provided measuring device—not a kitchen spoon.

Common side effects are mild: occasional nausea, diarrhea, or a skin rash. If you notice a severe rash, trouble breathing, or swelling of the face, stop the medication and seek medical help right away—that could be an allergic reaction.

Some medicines don’t mix well with amoxicillin. Tell your doctor about any blood thinners, oral contraceptives, or other antibiotics you’re taking. Alcohol isn’t a direct problem, but drinking a lot can worsen stomach irritation.

Finish the entire prescription even if you start feeling better after a few days. Stopping early can let bacteria survive, which may cause the infection to come back and increase resistance.
