INJECTION, POWDER, FOR SOLUTION

**Posology and method of administration** **Adults** The dosage and duration of therapy shall be established depending on type and severity of infection and the condition of the patient. The recommended daily dosage is as follows: - 500 mg IV every 8 hours in the treatment of pneumonia, UTI, gynaecological infections such as endometritis, skin and skin structure infections. - 1 g IV every 8 hours in the treatment of nosocomial pneumonias, peritonitis, presumed infections in neutropenic patients, septicaemia. - In meningitis the recommended dosage is 2 g every 8 hours. **Adults** When treating infections known or suspected to be caused by _Pseudomonas aeruginosa_, a dose of 1 g three times daily (or every 8 hours) or higher is recommended. There is limited safety data available to support a dose of above 2g three times daily (or every 8 hours). **Children** When treating infections known or suspected to be caused by _Pseudomonas aeruginosa_, a dose of at least 20mg/kg every 8 hours (up to 40mg/kg three times daily (or every 8 hours)) in children is recommended. Regular sensitivity testing is recommended when treating _Pseudomonas aeruginosa_ infection. **Dosage Schedule for Adults with Impaired Renal Function** Dosage should be reduced in patients with creatinine clearance less than 51 ml/min, as scheduled below.  Meropenem is cleared by haemodialysis and hemofiltration; if continued treatment with Archifar is necessary, it is recommended that the unit dose (based on the type and severity of infection) is administered at the completion of the haemodialysis procedure to restore therapeutically effective plasma concentrations. There is no experience with the use of meropenem in patients under peritoneal dialysis. **Dosage in Adults with Hepatic Insufficiency** No dosage adjustment is necessary in patients with hepatic insufficiency (see “Special warnings and precautions for use” – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). **Elderly Patients** No dosage adjustment is required for the elderly with normal renal function or creatinine clearance values above 50 ml/min. **Children** For children over 3 months and up to 12 years of age the recommended dose is 10–20 mg/kg every 8 hours depending on type and severity of infection, susceptibility of the pathogen and the condition of the patient. In children over 50 kg weight, adult dosage should be used. In meningitis the recommended dose is 40 mg/kg every 8 hours. There is no experience in children with renal impairment. **Method of Administration** Archifar can be given: - as an intravenous bolus injection over approximately 5 minutes or - by intravenous infusion over approximately 15 to 30 minutes using the specific available presentations. There is limited safety data available to support the administration of a 40 mg/kg bolus dose. There is limited safety data available to support the administration of a 2g bolus dose. Archifar to be used for bolus intravenous injection should be constituted with sterile Water for Injections (5 ml per 250 mg Meropenem). This provides an approximate concentration of 50 mg/ml. Archifar for intravenous infusion may be constituted with compatible infusion fluids (see “Incompatibilities” and “After reconstitution” – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).
