How does this medication work? What will it do for me?
This is a combination product containing two medications in the form of a gel: levodopa and carbidopa. It is used to treat Parkinson's disease in people who are responsive to levodopa treatment, have tried other types of Parkinson's disease medication combinations but continue to have symptoms. Levodopa - carbidopa intestinal gel is given using a small portable pump and tube that connects directly into the gut. The medication is given throughout the day, which allows a constant amount of medication to be in the blood and decrease the Parkinson's symptoms.
Levodopa helps to control the symptoms of Parkinson's disease by correcting the chemical imbalance in the brain that produces symptoms. The addition of carbidopa lowers the amount of levodopa that is required and may reduce some of the side effects of levodopa, such as nausea and vomiting.
Although levodopa helps relieve symptoms of Parkinson's disease, it does not slow down the progression of the disease.

How should I use this medication?
Treatment with levodopa - carbidopa should be started slowly and increased gradually to reduce the risk of side effects while gaining maximum benefit from the medication.
The recommended starting dose for people not already taking levodopa is 1 tablet, containing levodopa 100 mg and carbidopa 25 mg, 3 times a day. Your doctor will usually increase the dosage by 1 tablet daily every 3 days until the best results occur with the least amount of side effects. When the daily dose rises above 3 tablets daily, the dose should be divided into 4 to 6 daily doses. The maximum daily dose of levodopa is 1500 mg.
If you have already been taking levodopa and are starting levodopa - carbidopa, the dose will be much lower than the dose of levodopa taken as a single medction.

These factors may affect how you should use this medication.
Activities requiring alertness: There have been reports of sudden onset of sleep by individuals taking levodopa and carbidopa combination. The doctor should be informed immediately if any episodes of suddenly falling asleep occur.
Behavioural and mood changes: This medication has been known to cause mood swings, changes in behavior, and symptoms of depression. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you have an existing heart condition, you should discuss with your doctor about how your condition may affect your medication dosage, or how your dosage may affect your medical condition.
Device-related complications: A sudden decrease in treatment response with increased symptoms of Parkinson's disease may be due to problems with the tubing or pump device, including tube blockages or dislocations. The doctor should be informed immediately if this occurs.
Diet: Protein-rich diets such as diets that contain a lot of meat, poultry, or fish may reduce the beneficial effects of levodopa. Discuss appropriate diet options with your doctor.
