What is Duopa?

Duopa is an FDA (U.S. Food and Drug Administration) approved medication manufactured by AbbVie Inc. It is a combination of carbidopa (an aromatic amino acid decarboxylation inhibitor) and levodopa (an aromatic amino acid) indicated for the treatment of motor fluctuations in patients with advanced Parkinson’s disease.

What doses of Duopa are available?

Duopa is available in enteral suspension form, in the following doses: 4.63 mg carbidopa and 20 mg levodopa per mL.

Before starting Duopa, convert from all forms of levodopa to oral immediate-release carbidopa-levodopa tablets. Administer Duopa into the jejunum through a percutaneous endoscopic gastrostomy with a jejunal tube (PEG-J) with the CADD-Legacy 1400 portable infusion pump.

Duopa is taken over a 16 hour infusion period. The daily dose is based on patient titration and is composed of a morning dose, a continuous dose, and extra doses. The maximum recommended daily dose of Duopa is 2000 mg of the levodopa component (i.e., one cassette per day) over 16 hours. At the end of the daily 16 hour infusion, you will disconnect the pump from the PEG-J and take the night-time dose of oral immediate-release carbidopa-levodopa tablets.

The extra dose function can be used to manage acute “Off” symptoms that are not controlled by the morning dose and the continuous dose administered over 16 hours. The extra dose function is set at 1 mL when starting Duopa. The extra dose frequency is limited to one extra dose every 2 hours. Administration of frequent extra doses may cause or worsen dyskinesias.

Duopa is used at room temperature. Take one Duopa cassette out of the refrigerator and out of the carton 20 minutes before use. You may not receive the right amount of medication if the product is not given at room temperature.

Please read the full prescribing information and medication guide for the instructions for use and always speak with a healthcare professional about any changes to your dose so they can monitor and evaluate your condition.
