Amoxicillin Clavulanate: What It Is and How to Use It Safely
Amoxicillin clavulanate (often called Augmentin) combines amoxicillin, a penicillin antibiotic, with clavulanate, a beta-lactamase inhibitor. That extra piece helps the antibiotic work against bacteria that would normally resist plain amoxicillin. Doctors commonly prescribe it for ear infections, sinusitis, bronchitis, skin infections, and certain urinary tract infections.
Take it exactly as prescribed. Most adults use the 500/125 mg or 875/125 mg tablets twice a day, or 250/125 mg three times a day. There are also liquid forms for kids; shake the bottle well and measure doses with the provided syringe. Finish the full course even if you feel better after a few days—stopping early can let the infection come back or breed resistance.
Timing and food matter. Take the tablets with food to reduce stomach upset and help absorption. If you have trouble swallowing pills, many formulations can be cut or chewed—check the label or ask your pharmacist. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one; don’t double up.
Watch for side effects. The most common are diarrhea, nausea, and mild skin rash. If diarrhea is severe, bloody, or accompanied by stomach cramps and fever, call your doctor—these can be signs of C. difficile infection. Stop the drug and seek immediate care if you get hives, swelling of the face or throat, or trouble breathing—these are signs of a serious allergic reaction.
Check drug interactions and medical conditions. Amoxicillin clavulanate can interact with blood thinners like warfarin, certain birth control methods, and some other antibiotics. Tell your provider if you have liver disease—this medicine can affect liver tests and rarely cause liver injury, especially in older adults or with long courses. Also mention if you have a history of penicillin allergy.
Dosing adjustments may be needed for kidney problems. Your doctor will pick the right dose and schedule based on your age, weight, and kidney function. For children, dosing is usually by weight; do not guess doses from adult packaging.
Storage and disposal are simple: store tablets at room temperature away from moisture; keep the reconstituted liquid in the fridge and discard leftover liquid after the number of days listed on the label. Keep all medicines out of reach of children.
When to call your doctor: fever that doesn’t improve, spreading redness, worsening cough or trouble breathing, persistent vomiting or inability to keep fluids down, or any sign of severe allergic reaction. If symptoms don’t improve within 48–72 hours, follow up.
Questions? Ask your pharmacist or clinician about interaction with other drugs, pregnancy or breastfeeding safety, and whether a generic version is suitable. Amoxicillin clavulanate is a powerful tool when used correctly—know how to take it, what to watch for, and when to get help.
A few tips: keep a daily pill schedule or phone alarm, avoid mixing with alcohol if you have nausea or liver concerns, and record any rashes or bowel changes so you can report them. For pregnancy or breastfeeding, check with your provider before starting.
