How is Merrem given?
Merrem is injected into a vein through an IV. You may be shown how to use an IV at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.
Merrem is usually given every 8 hours. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Merrem must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.
Do not mix other injectable medications in the same IV bag or tubing used to given your Merrem injection.
Use a disposable needle only once, then throw away in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
Use Merrem for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Merrem will not treat a viral infection such as the common cold or flu.
If you use this medication long-term, you may need frequent medical tests at your doctor's office.
Store unopened vials of Merrem 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.
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.
