The main risk of an opioid overdose is respiratory
depression. It occurs most often in elderly or weakened
patients. Opioids may cause a severe drop in blood
pressure in vulnerable individuals.
Endain 80 mg
If you have not taken opioids before, you should not take
Endain 80 mg as such a high quantity may lead to a lifethreatening respiratory depression (breathing difficulties).
You may develop a tolerance with long-term use of
oxycodone. Therefore you may require higher doses of
oxycodone to achieve the desired pain control.
Long-term use of oxycodone in chronic pain patients may
lead to physical and mental dependence. You can reduce
the risk of dependence if you use Endain as instructed.

Withdrawal symptoms
If you stop the treatment suddenly, you may suffer from
withdrawal symptoms that include yawning, mydriasis,
lacrimation, rhinorrhoea, tremor, hyperhidrosis, anxiety,
agitation, palpitations, convulsions and insomnia. When
therapy with oxycodone is no longer necessary, you
should reduce the daily dose gradually in order to prevent
withdrawal symptoms.
If you are concerned about tolerance, dependence or
withdrawal symptoms, discuss this with your doctor.
Endain is not recommended in children under 12 years of
age because safety and efficacy are not established.
Other medicines and Endain
Tell your doctor or pharmacist if you are taking, have
recently taken or might take any other medicines.
You may increase the side effects of Endain (particularly
respiratory depression) by taking:
• medicines acting on the central nervous system, such
as sleeping and calming medications (sedatives,
• other medications which affect the nervous system
(phenothiazines, neuroleptics), antidepressants,
• medications for allergies or vomiting (antihistamines,
• other opioids and alcohol.
You may intensify specific side effects of Endain (such as
constipation, dry mouth or urinary excretion dysfunction)
by taking:
• medicines with anti-cholinergic effects, such as other
medications which act upon the nervous system
(medicines to treat psychiatric or mental disorders),
medications for allergies or vomiting (antihistamines,
• medicines for Parkinson’s disease.
In individual cases where Endain and anti-coagulants of
the coumarin type were used at the same time, a clinically
relevant decrease or increase in blood coagulation
(measured as INR) has been observed.

Antiobiotics (such as clarithromycin, erythromycin and
telithromycin, antifungal medicines (such as ketoconazole,
voriconazole, itraconazole and posaconazole), protease
inhibitors (such as boceprevir, ritonavir, indinavir,
nelfinavir and saquinavir), cimetidine (gastric acid
inhibitor) and grapefruit juice as well as paroxetine and
quinidine may inhibit the metabolism of oxycodone.
Some medicines, such as rifampicin, carbamazepin,
phenytoin and St John’s Wort may induce the metabolism
of oxycodone.
These capsules must not be used together with a
monoamine oxidase inhibitor, or if you have taken this
type of medicine in the last two weeks.
Endain with food, drink and alcohol
Drinking alcohol whilst taking Endain may make you
feel more sleepy or increase the risk of serious side
effects such as shallow breathing with a risk of stopping
breathing, and loss of consciousness. It is recommended
not to drink alcohol while you’re taking Endain.
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 or
pharmacist for advice before taking this medicine.
Do not take Endain if you are pregnant
You must not take Endain during pregnancy. There
are limited data from the use of oxycodone in pregnant
Oxycodone crosses the placenta into the blood circulation
of the baby.
Prolonged use of oxycodone during pregnancy can
cause withdrawal symptoms in newborns. Infants born
to mothers who have received opioids during the last 3
to 4 weeks before giving birth should be monitored for
respiratory depression.
Do not take Endain if you are breast-feeding.
Oxycodone hydrochloride passes into breast milk.

Driving and using machines
Endain may impair your ability to drive or operate
machinery. This is particularly likely:
• when you start the treatment with Endain,
• after a dose increase or product rotation (the use of
alternative medicines, to reduce side effects)
• if Endain is combined with alcohol or with medicines,
which acting on the central nervous system.
Please discuss with your doctor whether or not, or under
which conditions you may drive.
This medicine can impair cognitive function and can affect
a patient’s ability to drive safely. This class of medicine is in
the list of drugs included in regulations under 5a of the Road
Traffic Act 1988. When prescribing this medicine, patients
should be told:
• The medicine is likely to affect your ability to drive.
• Do not drive until you know how the medicine affects
• It is an offence to drive while you have this medicine in
your body over a specified limit unless you have a defence
(called the ‘statutory defence’).
• This defence applies when:
• The medicine has been prescribed to treat a medical or
dental problem; and
• You have taken it according to the instructions given by
the prescriber and in the information provided with the
• Please note that it is still an offence to drive if you are
unfit because of the medicine (i.e. your ability to drive is
being affected).”
Details regarding a new driving offence concerning driving
after drugs have been taken in the UK may be found here:
Talk to your doctor or pharmacist if you are not sure whether
it is safe for you to drive while taking this medidine.
Endain contains sucrose
If you have been told by your doctor that you have an
intolerance to some sugars, contact your doctor before
taking this medicinal product.

3. How to take Endain
Always take this medicine exactly as your doctor or
pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
Your doctor will adjust the dosage to the intensity of the
pain and to your personal sensitivity. Take the prescribed
number of capsules twice a day.
Adults and adolescents (more than 12 years of age)
• Initial dosage
Initial dosage is usually 1 capsule of Endain 10 mg
prolonged-release (10 mg oxycodone hydrochloride) at
12 hour intervals.
In order to minimize the incidence of adverse reactions,
you may benefit from a starting dose of 5 mg. In this
case, your doctor will prescribe you another oxycodone
product available with this specific 5 mg strength.
Further determination of the daily dosage and dosage
adjustments which may be required in the course
of treatment is to be made by the treating doctor
depending upon the preceding dosage. If you are already
receiving opioids, you may begin Endain treatment by
taking higher doses, based upon your previous opioid
Some patients receiving Endain on a fixed time
schedule require immediate-release painkillers for fast
relief from breakthrough pain. Endain prolongedrelease capsules are not intended for the treatment of
breakthrough pain.
• Recommended dosage
If you suffer from pain not related to a cancer,
40 mg per day of the active substance oxycodone
hydrochloride is normally enough; however, higher
doses may be necessary.
If you suffer from a cancer related pain, you normally
require doses of 80 to 120 mg of the active substance
oxycodone hydrochloride, which, in exceptional cases,
may be increased up to 400 mg.

While taking Endain, you need a regular monitoring with
respect to pain relief as well as other effects, in order
to achieve the best possible pain relief treatment, rapid
treatment of any occurring side effects, and to determine
continuation of treatment.
Older people
In elderly patients without kidney and/or liver problems,
dosage adjustment is usually not necessary.
High-risk patients
If you have not received opioids before and also suffer
from kidney and/or liver problems, you should initially
take half of the recommended adult dose. This also
applies to patients with low body weight and patients who
metabolise medications at slower rates. Therefore the lowest
recommended dose, i.e. 10 mg, may not be suitable as a
starting dose. In this case, your doctor will prescribe you
another oxycodone product available with this specific 5 mg
Please tell your doctor or pharmacist if you feel that the
effect of Endain is too strong or too weak.
Method of administration and duration of use
Endain is for oral use only. The capsules should never be
injected as this may lead to serious side effects, which may
Swallow the capsules whole in the morning and evening in
accordance to a fixed time schedule (e.g. in the morning at 8
a.m., in the evening at 8 p.m.).
You can take Endain with or without food but not
concomitantly with alcohol.
Swallow the capsules whole and do not break, crush or
chew the capsules or their contents (granules). Taking
broken, chewed or crushed granules leads to faster release
of the active substance and to the absorption of a potentially
lethal dose of oxycodone hydrochloride (see under “If you
take more Endain than you should”).
If you take more Endain than you should
If you have taken more capsules than prescribed, you should
inform a doctor, hospital or Poison Centre immediately.

you have completely forgotten to take your dose, this will
lead to unsatisfactory and/or insufficient pain relief.
Do not take a double dose to make up for a forgotten dose.
If you have forgotten to take your dose once, you may take
it later only if the next regular dose was scheduled more
than 8 hours later. You may then continue to follow your
