What is Merrem?
Merrem is used to treat severe infections of the skin or stomach.
Merrem is also used to treat bacterial meningitis (infection that causes inflammation of the tissue that covers the brain and spinal cord).
Before you receive Merrem, tell your doctor if you have a history of allergies to any antibiotic medications.
Before taking this medicine
You may not be able to use Merrem if you have ever had an allergic reaction to meropenem or to certain antibiotics, such as:
any penicillin antibiotic.
Tell your doctor if you have ever had:
epilepsy or other seizure disorder; or
kidney disease (or if you are on dialysis).
It is not known whether Merrem will harm an unborn baby. Tell your doctor if you are pregnant.
It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.
How is Merrem given?
Use Merrem exactly as directed. Follow all directions on your prescription label and read all medication guides or instruction sheets.
Merrem is given as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.
Merrem must be mixed with a liquid (diluent) before using it. Read and carefully follow any Instructions for Use provided with your medicine. Do not use this medicine if you don not understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.
Do not mix other injectable medications in the same IV bag or tubing with Merrem.
Prepare your injection only when you are ready to give it. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.
Use this medicine for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. Meropenem will not treat a viral infection such as the flu or a common cold.
If you use Merrem long-term, you may need frequent medical tests.
Store unopened vials at cool room temperature away from moisture and heat.
After mixing your medicine, you will need to use it within a certain number of hours. This will depend on the diluent and how you store the mixture (at cool room temperature, or in a refrigerator). Carefully follow the mixing and storage instructions provided with your medicine. Ask your pharmacist if you have questions.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while using Merrem?
Avoid driving or hazardous activity until you know how this medicine will affect you. Your reactions could be impaired.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
