Amoxicillin-Clavulanic Acid (Augmentin) contains two ingredients, Amoxicillin and Clavulanic Acid. It is an antibiotic used for treating bacterial infections, including but not limited to the following:
The dosage of Amoxicillin-Clavulanic Acid is usually based on the Amoxicillin component. The strength of each product, however, may combine the total amount of drug. For example, a 375-mg tablet of Augmentin contains 250 mg of Amoxicillin and 125 mg of Clavulanic acid. The dosage and frequency are specific to the product so always confirm with your doctor or pharmacist.
When taken by mouth, the usual adult dosage is 250 to 500 mg every 8 to 12 hours. The alternate dosage is 875 mg every 12 hours.
For children, your doctor will select the most appropriate Augmentin dose and it will depend on the type of infection, the age of your child, and their body weight. There are several liquid products that are available that have different ratios of Amoxicillin and Clavulanic acid. For example, Augmentin 125/31 mg liquid contains 125 mg of Amoxicillin and 31 mg Clavulanic acid (4:1 ratio), whereas Augmentin 400/57 mg liquid contains 200 mg of Amoxicillin and 28.5 mg of Clavulanic acid (7:1 ratio). The 7:1 ratio allows for higher dosing of Amoxicillin and keeps a similar dose of Clavulanic acid.
