Why is this medication prescribed?
Meropenem injection is used to treat skin and abdominal (stomach area) infections caused by bacteria and meningitis (infection of the membranes that surround the brain and spinal cord) in adults and children 3 months of age and older. Meropenem injection is in a class of medications called antibiotics. It works by killing bacteria that cause infection.
Antibiotics such as meropenem injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
How should this medicine be used?
Meropenem injection comes as a powder to be mixed with liquid and injected intravenously (into a vein). It is usually given every 8 hours. The length of treatment depends on your general health, the type of infection you have, and how well you respond to the medication. Your doctor will tell you how long to use meropenem injection. After your condition improves, your doctor may switch you to another antibiotic that you can take by mouth to complete your treatment.
You may receive meropenem injection in a hospital, or you may administer the medication at home. If you will be receiving meropenem injection at home, your healthcare provider will show you how to use the medication. Be sure that you understand these directions and ask your healthcare provider if you have any questions.
You should begin to feel better during the first few days of treatment with meropenem injection. If your symptoms do not improve or if they get worse, call your doctor.
Use meropenem injection until you finish the prescription, even if you feel better. If you stop using meropenem injection too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
