Product Description

This CMI answers some common questions about Duodopa intestinal gel.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Duodopa against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Duodopa is used for

Duodopa intestinal gel is used to control severe involuntary movements of advanced Parkinson's disease.

Parkinson's disease is a condition where you lose control of your limbs and posture. Loss of control may be mild and can become severe.

Duodopa intestinal gel belongs to a group of medicines called Anti-Parkinson medications. These medicines work by increasing the amount of a chemical which the brain requires to work properly. This helps you to gain control over your movements and posture again.

Duodopa may be used alone, or in combination with other medicines to treat your condition.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

There is no evidence that Duodopa is addictive.

This medicine is only available with a doctor's prescription.

Duodopa is not recommended for use in children under 18 years as its safety and effectiveness in that age group have not been established.

How to use it

How much to use

The total amount of Duodopa used each day includes three individually adjusted doses: the morning bolus dose, the continuous maintenance dose, and extra bolus doses.

Usually 5-10 mL (not more than 15 mL).

Continuous maintenance dose:
Between 1mL and 10 mL per hour. Usually 2-6 mL per hour.

Extra doses:
As required. Your doctor will discuss this with you.

Daily intake of levodopa as Duodopa: 1640 mg/day

Morning dose: 140 mg = 7 mL (including volume to fill the intestinal tube)

Continuous maintenance dose: 1500 mg/day

1500 mg/day: 20 mg/mL = 75 mL Duodopa per day

The intake is calculated over 16 hours: 75 mL/16 hours = 4.7 mL/hour.
