Ertapenem, sold under the brand name Invanz, is a carbapenem antibiotic medication used for the treatment of infections of the abdomen, the lungs, the upper part of the female reproductive system, and the diabetic foot.[7][8]

The most common side effects include diarrhoea, nausea, headache, and problems around the area where the medicine is infused. It can significantly reduce the concentrations of valproic acid, an anti-seizure medication, in the blood to the point where it loses its effectiveness.[6]

Ertapenem was approved for medical use in the United States in November 2001,[5][9] and in the European Union in April 2002.[6] It is marketed by Merck.[5][6]
