How should I use carbidopa and levodopa enteral?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
This medicine is infused directly into the small intestine through a tube inserted into the wall of your stomach through a surgical incision. This tube is attached to an infusion pump.
A healthcare provider will program the pump and show you how to use it. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Duopa comes in a plastic cassette to attach to the infusion pump. Each cassette is to be used only one time and then thrown away.
Duopa is usually infused over a 16-hour period.
Do not stop using this medicine or change your dose without your doctor's advice.
You may need to take a pill form of carbidopa and levodopa at night or whenever your infusion pump is disconnected for longer than 2 hours.
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Duopa.
Store cassettes in their original carton in the refrigerator, do not freeze.
Take a cassette out of the refrigerator and let it reach room temperature for 20 minutes, protected from light. Do infuse Duopa from a cold cassette.
What happens if I miss a dose?
You may need to use extra medicine to make up a missed dose. Call your doctor for instructions if you stop your infusion or disconnect your pump for longer than 2 hours.
