1. What Duodopa is and what it is used for

Duodopa belongs to a group of medicines for Parkinson’s disease.

Duodopa is a gel that goes through a pump and a tube into your gut (small intestine). In the gel there are two active substances:

  • Levodopa.
  • Carbidopa.

How Duodopa works

  • In the body, levodopa is made into something called ‘dopamine’. This adds to the dopamine already in your brain and spinal cord. Dopamine helps transfer signals between nerve cells.
  • Too little dopamine causes Parkinson’s disease signs like tremor, feeling stiff, slow movement, and problems keeping your balance.
  • Treatment with levodopa increases the amount of dopamine in your body. This means it reduces these signs.
  • Carbidopa improves the effect of levodopa. It also reduces the side effects of levodopa.

2. What you need to know before you use Duodopa

Do not use Duodopa if:

  • You are allergic to levodopa, carbidopa or any of the other ingredients of this medicine (listed in section 6).
  • You have an eye problem called ‘narrow-angle glaucoma’.
  • You have severe heart problems.
  • You have a severe uneven heart beat (arrhythmia).
  • You have had a severe stroke.
  • You are taking medicines for depression called selective MAO-A inhibitors and non-selective MAO-inhibitors such as moclobemide or phenelzine.
  • You have a tumour of the adrenal gland (pheochromocytoma).
  • You have hormone problems such as too much cortisol (Cushing’s syndrome) or your thyroid hormone levels are too high (hyper-thyroidism).
  • You have ever had skin cancer, or you have any unusual moles or marks on your skin which have not been looked at by your doctor.

Do not use Duodopa if any of the above apply to you. If you are not sure, talk to your doctor before having Duodopa.

Warnings and precautions:

Talk to your doctor before using Duodopa if:

  • You have ever had a heart attack, blocked blood vessels in your heart, or any other heart problems including an uneven heart beat (arrhythmia).
  • You have a lung problem – such as asthma.
  • You have ever had a hormone problem.
  • You have ever had depression with thoughts of suicide or any other mental problems.
  • You have an eye problem called ‘wide-angle glaucoma’.
  • You have ever had a stomach ulcer.
  • You have ever had fits (convulsions).
  • You have ever had surgery in your upper stomach area (upper abdominal surgery).

If any of the above apply to you (or you are not sure), talk to your doctor before having Duodopa.

Look out for side effects

Neuroleptic Malignant Syndrome

Do not stop having Duodopa or lower your dose unless a doctor tells you to. This is because suddenly stopping or lowering your Duodopa dose quickly may cause a serious problem called ‘Neuroleptic Malignant Syndrome’ (see section 4 ‘Serious side effects’).

Feeling sleepy or dizzy

If you suddenly fall asleep (sleep attacks) or feel very sleepy, or if you feel light-headed or dizzy:

  • Do not drive or use any tools or machines until you feel fully awake again or you no longer feel light-headed or dizzy (see section 2 ‘Driving and using machines’).

Skin changes

Tell your doctor, pharmacist or nurse if you notice any unusual marks or moles on your skin that appear or get worse (see section 4 ‘Other side effects’).

Impulse control disorders – changes in your behaviour

Tell your doctor if you, your family or carer notices you are developing urges or cravings to behave in ways that are unusual for you. Or you cannot resist the impulse, drive or temptation to carry out certain activities that could harm yourself or others. These behaviours are called ‘impulse control disorders’ and can include:

  • Addictive gambling.
  • Excessive eating or spending.
  • Abnormally high sex drive or an increase in sexual thoughts or feelings.

Your doctor may need to review your treatments. They will discuss ways of managing or reducing these symptoms, with you (see section 4 ‘Impulse control disorders – changes in your behaviour’).

Problems using the pump or tube

There may be some problems linked to using the pump and tube:

  • You become less able to handle the pump and tube, your Parkinson’s disease symptoms get worse or it is harder to move (bradykinesia) –. The pump and tube may not be working properly.
  • You have pain in your stomach area, feel sick (nausea) and are sick (vomit) – tell your doctor straight away if this happens (see Section 4 ‘Serious side effects’).
  • You may get other side effects affecting your gut (intestine) and where the tube goes in (see section 4 ‘Problems using the pump or tube’).

Duodopa and cancer

In the body, carbidopa (an active substance of Duodopa) is broken down into something called ‘hydrazine’. It is possible that hydrazine could damage your genetic material which could lead to cancer. However, it is not known if the amount of hydrazine produced when taking a normal dose of Duodopa can cause this.

Tests or checks

Your doctor may do some blood tests if you are having this medicine.

Operations

Before you have an operation (including a dental operation), tell the doctor (or dentist) that you are having Duodopa.

Children and adolescents

Duodopa should not be used in children or young people under the age of 18 years.

Other medicines and Duodopa

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This includes medicines obtained without a prescription, and herbal medicines.

Do not use Duodopa if you are taking:

  • Medicines for depression called selective MAO-A inhibitors and non-selective MAO inhibitors such as moclobemide or phenelzine.

Talk to your doctor or pharmacist before starting Duodopa if you are taking other medicines for:

  • Anaemia – such as iron tablets.
  • Tuberculosis – such as isoniazid.
  • Anxiety – such as benzodiazepines.
  • Sickness – such as metoclopramide.
  • High blood pressure – such as anti-hypertensives.
  • Spasms in the blood vessels – such as papaverine.
  • Fits (convulsions) or epilepsy – such as phenytoin.
  • Parkinson’s disease – such as tolcapone, entacapone, amantadine.
  • Mental problems – such as anti-psychotics including phenothiazines, butyrophenones and risperidone.
  • Severe allergic reactions, asthma, chronic bronchitis, heart disease and low blood pressure – such as anti-cholinergics and sympatho-mimetics.
  • You are taking a medicine which may cause low blood pressure. This could cause something called ‘orthostatic hypotension’ – this can make you dizzy when getting up from a chair or bed. Duodopa can make this worse. Always change positions slowly.

Duodopa with food and drink

For some patients, Duodopa may not work well if it is taken with, or shortly after eating protein-rich food – such as meats, fish, dairy products, seeds and nuts. Talk to your doctor if you think this applies to you.

Pregnancy and breast-feeding

  • If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before starting treatment with Duodopa.
  • Do not use Duodopa if you are breast-feeding.

Driving and using machines

Do not drive or use any tools or machines until you are sure how Duodopa affects you.

  • Duodopa may make you feel very sleepy, or you may sometimes find yourself suddenly falling asleep (sleep attacks).
  • Duodopa may lower your blood pressure, which can make you feel light-headed or dizzy.

Do not drive or use any tools or machines until you feel fully awake again or you no longer feel light-headed or dizzy.

3. How to use Duodopa

Always take this medicine exactly as your doctor, pharmacist or nurse has told you. Check with your doctor or pharmacist if you are not sure.

About Duodopa gel and the pump

  • Duodopa is a gel that goes through a pump and a tube into your gut (small intestine).
  • The gel comes in a plastic cassette. The cassette is connected to a pump.
  • The pump is connected to a tube which is placed into your gut (small intestine).
  • The pump gives you a small dose throughout the day. This means that the level of the medicine in your blood stays the same. It also means some of the movement side effects are lower.

How much to use

  • Your doctor will decide how much Duodopa you should use and for how long.
  • Usually, a larger morning dose (called the ‘bolus dose’) is given. This allows you to quickly get the right amount of medicine in your blood. After that dose, a steady (‘maintenance’) dose is given.
  • If needed, you may have extra doses – this will be decided by your doctor.

If you use more Duodopa than you should

If you have used more Duodopa than you should, talk to your doctor or go to a hospital straight away. Take the medicine pack with you. The following effects may happen:

  • Problems opening your eyes.
  • Muscle spasms you cannot control in your eyes, head, neck and body (dystonia).
  • Movement you make without wanting to (dyskinesia).
  • Unusual fast, slow or uneven heart beats (arrhythmia).

If you forget to use Duodopa

  • Start your pump, with your normal dose, as soon as possible.
  • Do not increase your dose to make up for a forgotten dose.

If you stop or lower your dose of Duodopa

Do not stop having Duodopa or lower your dose unless a doctor tells you to. This is because suddenly stopping or lowering your Duodopa dose quickly may cause a serious problem called ‘Neuroleptic Malignant Syndrome’. This problem is more likely to happen if you are also taking a medicine called an ‘anti-psychotic’ (see section 4 ‘Serious side effects’).

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

4. Possible side effects
