What is the dosage for amoxicillin and clavulanic acid?

Augmentin should be taken on a full stomach to reduce stomach upset. No more than one tablet should be taken at a time since the extra clavulanic acid can cause stomach upset. Recommended adult doses are 500 mg every 8-12 hours, 250 mg every 8 hours, 875 mg every 12 hours, or 2000 mg every 12 hours. Dosing is based on the amoxicillin component. Pediatric patients weighing more than 40 kg should receive adult doses. Pediatric patients weighing less than 40 kg should receive 20 to 45 mg/kg every 8 or 12 hours.

Which drugs or supplements interact with amoxicillin and clavulanic acid?

Co-administration of probenecid, a drug used for treating gout, prevents the normal elimination of amoxicillin by the kidneys and can cause high, toxic blood levels of amoxicillin. Augmentin may decrease the effectiveness of birth control pills, increasing the risk of unexpected pregnancies. Combining Augmentin and allopurinol (Zyloprim, Aloprim) may increase the occurrence of skin rash.
