In the treatment of acute uncomplicated gonorrhea - 3 g once (in combination with probenecid). Patients with impaired renal function in creatinine clearance 10-40 ml / min interval between doses should be increased to 12 h and if creatinine clearance is less than 10 ml / min interval between doses should be 24 hours.
When parenteral use in adults IM - 1 g 2 times / day, IV (with normal renal function) - 2.12 g / day. Children IM 50 mg / kg / day, single dose - 500 mg, the frequency of administration - 2 times / day; IV - 100-200 mg / kg / day.

Perhaps the development of superinfection due to growth insensitive to the drug microflora. In the case of superinfection requires removal of Amoxicillin Trihydrate and the corresponding change in antibiotic therapy. When treating patients with bacteremia may develop bacteriolysis reaction.
Patients who have an increased sensitivity to penicillin, may be cross-allergic reactions to cephalosporin antibiotics.

Amoxicillin Trihydrate increases the effects of indirect anticoagulants inhibiting intestinal microflora, reduces the synthesis of vitamin K and prothrombin index.
Amoxicillin Trihydrate reduces the effect of drugs, in the process of metabolism that produce PABA.
Probenecid, diuretics, allopurinol, phenylbutazone, NSAIDs decrease the tubular secretion of Amoxicillin Trihydrate, which can be accompanied by an increase in its concentration in blood plasma.
Antacids, glucosamine, laxatives, aminoglycosides, slow down and reduce, and ascorbic acid increases the absorption of Amoxicillin Trihydrate.
With the combined use of Amoxicillin Trihydrate and clavulanic acid pharmacokinetics of both components unchanged.
