It is metabolized in kidney reducing its half life so cilastatin is given with it to halt its renal metabolism.

Imipenem belongs to carbapenem family of antibiotics. Carbapenem antibiotics can cause seizures specially in people with nervous system disorders or renal failure. Dose must be reduced in patients with renal (kidney) dysfunction otherwise patient's kidneys will be damaged more and since they are already in weak state, it can prove dangerous to the patient.
