levodopa/dopa-decarboxylase inhibitor preparation, the
previous preparation should be discontinued at least

l PATIENT AND CARER ADVICE Manufacturer advises
patients and their carers should be informed of the risk of
developing dopamine dysregulation syndrome; addictionlike symptoms should be reported.
Driving and skilled tasks Sudden onset of sleep Excessive
daytime sleepiness and sudden onset of sleep can occur
Patients starting treatment with these drugs should be
warned of the risk and of the need to exercise caution
when driving or operating machinery. Those who have
experienced excessive sedation or sudden onset of sleep
should refrain from driving or operating machines until
these effects have stopped occurring.
Management of excessive daytime sleepiness should
focus on the identification of an underlying cause, such as
depression or concomitant medication. Patients should be
counselled on improving sleep behaviour.

Scottish Medicines Consortium (SMC) decisions
The Scottish Medicines Consortium has advised (June 2016)
that co-careldopa (Duodopa ®) intestinal gel is accepted for
restricted use within NHS Scotland, for the treatment of
advanced levodopa-responsive Parkinson’s disease with
severe motor fluctuations and hyper-/dyskinesia when
available combinations of Parkinson medicinal products
have not given satisfactory results, only in patients not
eligible for deep brain stimulation. This advice is
contingent upon the continuing availability of the Patient

l PATIENT AND CARER ADVICE Manufacturer advises
patients and their carers should be informed of the risk of
developing dopamine dysregulation syndrome; addictionlike symptoms should be reported.
Driving and skilled tasks Sudden onset of sleep Excessive
daytime sleepiness and sudden onset of sleep can occur
with dopamine-receptor agonists.
Patients starting treatment with these drugs should be
warned of the risk and of the need to exercise caution
when driving or operating machinery. Those who have
experienced excessive sedation or sudden onset of sleep
should refrain from driving or operating machines until
these effects have stopped occurring.
Management of excessive daytime sleepiness should
focus on the identification of an underlying cause, such as
depression or concomitant medication. Patients should be
counselled on improving sleep behaviour.
Drugs and driving Prescribers and other healthcare
professionals should advise patients if treatment is likely
to affect their ability to perform skilled tasks (e.g. driving).
This applies especially to drugs with sedative effects;
patients should be warned that these effects are increased
by alcohol. General information about a patient’s fitness to
drive is available from the Driver and Vehicle Licensing
2015 legislation regarding driving whilst taking certain
drugs, may also apply to apomorphine, see Drugs and
driving under Guidance on prescribing p. 1.
Hypotensive reactions Hypotensive reactions can occur in
some patients taking dopamine-receptor agonists; these
can be particularly problematic during the first few days of
treatment and care should be exercised when driving or
