What Duodopa is and what it is used for

What Duodopa is used for
Duodopa belongs to a group of medicines for treatment
of Parkinson’s disease.
Duodopa contains two medicines in a gel:
levodopa and carbidopa monohydrate.
How Duodopa works

Levodopa is made into dopamine in the body.
Dopamine is present in your brain and in your
spinal cord. It helps transfer signals between
nerve cells. Too little dopamine causes Parkinson’s
disease signs like tremor, feeling rigid, slow
movements, and problems keeping your balance.

Treatment with levodopa increases the amount of
dopamine in your body and so reduces these signs

Carbidopa monohydrate is added to improve
the effect and reduce the undesirable effects of

Before you take Duodopa

You are allergic (hypersensitive) to levodopa,
carbidopa monohydrate or any of the other
ingredients of Duodopa (listed in Section 6)

You have an eye problem called ‘narrow-angle

You have severe liver or kidney problems

You have severe heart disease

You have a severe irregular heart beat (arrhythmia)

You have an acute stroke

MKP-12-XXX1.indd 2-3

You have depression and have recently (within the
previous two weeks) been treated with either a
medicine called a ‘non-selective MAO inhibitor’
or a ‘selective MAO A inhibitor’
You have a growth in your adrenal gland
(adrenocortical tumour)
You have hormonal problems (such as overproduction of adrenocortical or thyroid hormones)

Take special care with Duodopa:
Check with your doctor before or while taking
Duodopa if:

You have a severe heart disease or have had a
heart attack

You have a lung problem (such as bronchial

You have a hormonal problem

You have depression with suicidal tendencies or
any mental problem

You are taking medicines used to treat depression
or other mental disorders (antipsychotics)

You have an eye problem called ‘wide-angle

You have ever had a stomach ulcer

You have fits (convulsions)

You experience failure to resist gambling impulses
(pathological gambling), altered sexual interest and
behaviour (increased sex drive and hypersexuality)

You have had previous upper abdominal surgery

You experience a reduced ability to handle the
device system (pump or tube connections)

02.11.12 10:19

You experience worsening of execution of
movements (bradykinesia) which may indicate a
malfunction of the device system

Having a PEG-J tube in your intestine may result
in the risk of undigested food getting stuck around
the tube. If you have the following symptoms,
please contact your doctor immediately: abdominal
pain, nausea and vomiting.
Duodopa should not be given to children or adolescents
under the age of 18 years. If you are not sure if any
of the above applies to you, talk to your doctor or
pharmacist before taking Duodopa.
Duodopa contains a substance called hydrazine,
a breakdown product of one of the ingredients
(carbidopa). This substance can cause damage to
the genetic material which could theoretically lead to
cancer. The risk for humans when exposed to hydrazine
at recommended doses of Duodopa is not known.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or
have recently taken any other medicines. This includes
medicines obtained without a prescription, including
herbal medicines.
In particular, talk to your doctor or pharmacist before
starting Duodopa if you are taking medicines for:

Parkinson’s disease, severe allergic reactions,
asthma, chronic bronchitis, heart diseases and
low blood pressure (such as Anticholinergics and

Fits (convulsions) or epilepsy

MKP-12-XXX1.indd 4-5

High blood pressure
Mental problems
Depression (such as ‘tricyclic antidepressants’ or
‘non-selective monoamine oxidase inhibitors’)

Tuberculosis (such as isoniazide)

Anxiety (such as benzodiazepines)

Anaemia (such as iron tablets)

Sickness (such as metoclopramide)

Spasms in the blood vessels (such as papaverine).
If you are not sure if any of the above applies to
you, talk to your doctor or pharmacist before taking
Pregnancy and breast-feeding

You are pregnant or are planning to become
pregnant while taking Duodopa. Unless you have

How Duodopa is given

Duodopa is a gel which comes in a plastic cassette.
These are connected to a pump.

The pump is connected to a tube which is placed
into the small intestine.

You are given a small dose continuously during
day-time. This means that the level of the medicines
in your blood is more constant and also some of the
movement side effects are lower.
How much Duodopa is given

Your doctor will decide how much Duodopa you
should be given and for how long

Usually, a larger morning dose is given using
the pump (bolus dose) to quickly reach the
correct blood level. After that dose, a continuous
(maintenance) dose is given

If needed, extra doses may be given.
If you have more Duodopa than you should
If you have had 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 eye (blepharospasm),
uncontrollable muscle spasms affecting your eyes,
head, neck and body (dystonia), involuntary movements
(dyskinesia),unusual fast, slow or uneven heart beats
If you stop or lower your dose of Duodopa
It is important that you do not stop having Duodopa or
lower your dose until told to do so by your doctor.
Suddenly stopping or lowering your Duodopa dose may
result in a serious problem called ‘Neuroleptic Malignant

MKP-12-XXX1.indd 6-7

Syndrome’. The signs may include:

Fast heart beat, changing blood pressure and
sweating followed by fever

Faster breathing, muscle stiffness, lower
consciousness and coma

Higher levels of a protein in your blood (an enzyme
called creatine phosphokinase). This is measured by
your doctor.
This problem is more likely to happen if you are also
taking a medicine called an ‘antipsychotic’.
If you have any further questions on the use of this
product, ask your doctor or pharmacist.

Possible side effects

Like all medicines, Duodopa can cause side effects,
although not everybody gets them.
Stop taking Duodopa and tell your doctor straight
away if you notice any of the following side effects you may need urgent medical treatment:

Swelling of the face, tongue or throat which may
make it difficult to swallow or breathe; nettle type
skin rash. These may be signs of an allergic type
reaction called ‘angioedema’

Fever, sore throat or mouth or trouble passing water.
These may be signs of a white blood cell problem
called ‘agranulocytosis’. Your doctor will take a
blood sample to check the levels of your white
blood cells.
The following side effects have also been observed with
drugs containing levodopa and carbidopa monohydrate:

02.11.12 10:19

The following very common complications have been
reported for the ‘tube delivery system’:

Leaks at the connections and leakage of gastric fluid

Blockade of flow of Duodopa due to occlusion,
kinking and knotting of the tubing. Should complete
failure of the tube or pump occur see your doctor
immediately. The doctor will treat you with oral
levodopa/carbidopa until the problem is solved.

Dislocation of the tube e.g. to the stomach
(resulting in decreased treatment response)

Local infection around the site of tube entering
the stomach area (stoma), inflammation of the
abdominal cavity (peritonitis), and perforation of
adjacent organs, bleeding and abdominal pain,
especially during tube placement.
If any of the side effects gets serious, or if you notice
any side effects not listed in this leaflet, please tell your
doctor or pharmacist.

Medicines should not be disposed of via wastewater or
household waste. Ask your pharmacist how to dispose of
