Why is this medicine prescribed?
Imipenem, cilastatin, and relebactam injection is used to treat adults with certain serious urinary tract infections including kidney infections, and certain serious abdominal (stomach) infections when there are few or no other treatment options. It is also used to treat certain types of pneumonia that developed in adults who are on ventilators or who were already in a hospital. Imipenem is in a class of medications called carbapenem antibiotics. It works by killing bacteria. Cilastatin is in a class of medications called dehydropeptidase inhibitors. It works by helping imipenem stay active in your body for a longer period of time. Relebactam is in a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from destroying imipenem.
Antibiotics such as imipenem, cilastatin, and relebactam injection will not work for colds, flu, or other viral infections. Taking or using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

What should I know about storage and disposal of this medication?
Your healthcare provider will tell you how to store your medication. Store your medication only as directed. Make sure you understand how to store your medication properly.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http://goo.gl/c4Rm4p ) for more information if you do not have access to a take-back program.
What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your body's response to imipenem, cilastatin, and relebactam injection.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
