Imipenem(250 mg)


Imipenem in combination with cilastatin (inhibitor of enzyme dehydropeptidase) is used to treat bacterial infections of lung (pneumonia), urinary tract, abdomen, blood, skin and soft tissue. It is also used to treat infections during or after delivery. It may be used in the management of fever of patients with reduced immunity due to low white blood cells (neutropenia).

How it works

Imipenem belongs to a group of medicines called carbapenem beta-lactam antibiotics. It kills bacteria by inhibiting bacterial cell wall (outer coating of bacteria) formation. As a result, the bacterial cell wall is weakened and ruptures, thereby killing the bacteria.

Common side effects

Decreased urination, Bruise, Bleeding, Chills, Confusion, Convulsion, Diarrhoea, Abdominal pain, Dizziness, Shortness of breath, Fever, Rash, Itching, Sore mouth, Sore throat, Stomach upset, Facial swelling, Wheezing, Vomiting
Cilastatin(250 mg)


Cilastatin is used in combination with imipenem to protect it from an enzyme called dehydropeptidase present in the kidneys in order to increase the antibacterial effect of imipenem. This combination is used in the treatment of complicated intra-abdominal infections, severe pneumonia, intra- and post-partum infections (infections that can occur during and after vaginal and cesarean delivery), complicated urinary tract infections, complicated skin and soft tissue infections, management of neutropenic patients (patients with abnormally few neutrophils in the blood) with fever and in the treatment of patients with bacteraemia (the presence of bacteria in the blood) that occurs in association with, or is suspected to be associated with, any of the infections listed above. 

How it works

Cilastatin is an enzyme inhibitor that belongs to the class of drugs called as renal dehydropeptidase and leukotriene D4 peptidase inhibitors. It inhibits the enzyme dehydropeptidase present in the kidneys which hydrolyses the antibiotic imipenem and thus helps in increasing the levels of imipenem which subsequently increases the antibacterial activity thereby preventing infections.

Common side effects

Vomiting, Nausea, Allergic reaction, Confusion, Diarrhoea, Fever, Rash
