How is meropenem given?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Meropenem 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.
Meropenem must be mixed with a liquid (diluent) before using it. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Prepare an injection only when you are ready to give it. Do not mix other injectable medications in the same IV bag or tubing with meropenem. 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 meropenem 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 must 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 medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not use two doses at one time.
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 meropenem?
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.

Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).
Seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include: skin rash, fever, swollen glands, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes.

- sores or white patches in your mouth or throat (yeast infection or "thrush");
