Augmentin is a widely prescribed antibiotic that combines amoxicillin with clavulanate potassium. This combination helps fight bacteria that are resistant to amoxicillin alone. Doctors often recommend Augmentin to treat infections like sinusitis, pneumonia, ear infections, urinary tract infections, and skin infections.
Because it’s a powerful medicine, taking the right dose is very important. Too little might not clear the infection, and too much can cause side effects. This guide will help you understand how much Augmentin to take, when to take it, and what to do if you miss a dose.

Augmentin Dosage by Condition
Sinusitis
Adults typically take 500 mg every 12 hours or 875 mg every 12 hours for 5 to 7 days. Children’s doses depend on weight, usually around 45 mg/kg/day divided every 12 hours.
Urinary Tract Infection
For adults, 500 mg every 12 hours for 7 to 10 days is common. Children’s doses are calculated based on weight, as with other infections.
Skin and Soft Tissue Infections
Adults often take 875 mg every 12 hours for 7 to 10 days. Children’s doses are adjusted by weight and given every 12 hours.
What is the Typical Augmentin Dose for Adults?
Adults usually take Augmentin tablets in doses ranging from 250 mg to 875 mg of amoxicillin combined with clavulanate potassium. The exact dose depends on the infection’s severity and type. For mild to moderate infections, 500 mg every 12 hours is common. For more serious infections, doctors may prescribe 875 mg every 12 hours.
It’s important to follow your healthcare provider’s instructions closely. Taking the medicine at regular intervals helps keep the antibiotic active in your body and fights the infection effectively.
What is the Typical Augmentin Dose for Children?
Children’s doses depend on their weight and the infection being treated. Usually, the dose is calculated as 25 to 45 mg of amoxicillin per kilogram of body weight per day, divided into two or three doses. The oral suspension form makes it easier to adjust doses for kids.
Always use the measuring device that comes with the medicine to ensure accurate dosing. Never guess the amount, as too much can cause side effects and too little may not clear the infection.
What to Do If You Miss a Dose of Augmentin?
If you forget to take a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed one and continue your regular schedule. Do not take two doses at once to make up for the missed dose. This helps avoid side effects and keeps the medicine working properly.
How to Adjust Your Augmentin Dose for Certain Medical Conditions
Liver Disease Adjustment
People with liver problems may need a lower dose or closer monitoring. Augmentin can affect the liver, so doctors adjust doses to keep treatment safe.
Kidney Disease Adjustment
Kidney function affects how the body clears Augmentin. Patients with kidney problems often require dose adjustments to avoid buildup and side effects.
Augmentin Overdose and Warnings
Taking too much Augmentin can cause nausea, vomiting, diarrhea, and sometimes more serious effects like seizures. If an overdose is suspected, seek medical help immediately.
Some people may be allergic to penicillin antibiotics like Augmentin. Signs of an allergic reaction include rash, itching, swelling, dizziness, and trouble breathing. Stop taking Augmentin and get emergency care if these occur.
