What Daloxy is and what it is used for

Daloxy is a strong analgesic or “painkiller” and belongs to the group of opioids.
It is used to treat severe pain, which requires treatment with an opioid analgesics because other painkillers
have not been effective.


What you need to know before you take Daloxy

Do not take Daloxy:

if you are allergic to oxycodone or any of the other ingredients of this medicine (listed in section 6),

if you suffer from severe breathing problems, such as severe respiratory depression,

if you suffer from elevated carbon dioxide levels in the blood (hypercapnia),

if you suffer from severe chronic obstructive airways disease,

if you have a heart problem after long-term lung disease (cor pulmonale),

if you suffer from severe bronchial asthma,

if you have a condition where the small bowel does not work properly (paralytic ileus),

if you are pregnant or breast-feeding,

If you have acute severe stomach pain or suffer from a delayed stomach emptying.
Warnings and precautions
Talk to your doctor or pharmacist before taking Daloxy

if you are elderly or weak,

if you have severe lung-, liver- or kidney problems,

if you have myxoedema (a disease of the thyroid gland), underactive thyroid gland (hypothyroidism),

if you have adrenal insufficiency (Addison’s disease),

if you have an enlarged prostate gland (prostate hypertrophy),

if you have toxic psychosis (a mental disorder as a result of an intoxication induced by, for example,
if you suffer from alcoholism, delirium tremens (a state of violent mental agitation caused by alcohol
if you have known opioid dependence (any substance that behaves in the body like an opium-derived
if you have a history of drug or alcohol abuse,
if you have inflammation of the pancreas (pancreatitis),
if you have gallstones (biliary calculi),
if you have obstructive and inflammatory intestinal diseases; with the occurrence or suspicion of paralytic
ileus, Daloxy should be immediately discontinued,
if you have conditions involving increased cerebral pressure,
if you have circulatory system dysfunction,
if you have epilepsy or a predisposition to convulsions,
if you use MAO inhibitors,
if you are going to have an operation,

Please talk to your doctor if this information applies, or has applied to you.
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.
Daloxy 80 mg
If you have not taken opioids before, you should not take Daloxy 80 mg as such a high quantity may lead to
a life-threatening 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 Daloxy 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.
Daloxy is not recommended in children under 12 years of age because safety and efficacy are not
Other medicines and Daloxy
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 Daloxy (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),

medications for allergies or vomiting (antihistamines, anti-emetics),

other opioids and alcohol.

You may intensify specific side effects of Daloxy (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, antiemetics),

medicines for Parkinson’s disease.
In individual cases where Daloxy 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.
Daloxy with food, drink and alcohol
Drinking alcohol whilst taking Daloxy 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 Daloxy.
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 Daloxy if you are pregnant
You must not take Daloxy 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 Daloxy if you are breast-feeding. Oxycodone hydrochloride passes into breast milk.
Driving and using machines
Daloxy may impair your ability to drive or operate machinery. This is particularly likely:
 when you start the treatment with Daloxy,
 after a dose increase or product rotation (the use of alternative medicines, to reduce side effects)
 if Daloxy 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 you.
 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 medicine.
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).”

Daloxy 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.


How to take Daloxy

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 Daloxy 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 Daloxy treatment by taking higher doses, based upon your previous opioid
Some patients receiving Daloxy on a fixed time schedule require immediate-release painkillers for fast relief
from breakthrough pain. Daloxy prolonged-release 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 Daloxy, 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 strength.
Please tell your doctor or pharmacist if you feel that the effect of Daloxy is too strong or too weak.
Method of administration and duration of use
Daloxy is for oral use only. The capsules should never be injected as this may lead to serious side effects,
which may fatal.
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 Daloxy 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 Daloxy than
you should”).
If you take more Daloxy than you should
If you have taken more capsules than prescribed, you should inform a doctor, hospital or Poison Centre
immediately. Keep the packaging of the medicine at hand.
The following may occur:
 narrowed pupils,
 respiratory depression,
 somnolence progressing up to stupor or loss of consciousness (coma),
 decreased tension of skeletal muscles,
 slowed pulse rate and drop in blood pressure,
 loss of consciousness (coma), water retention in the lung and circulatory collapse may occur in more
severe cases and may lead to death.
If you have taken more Daloxy than you should have, never engage in situations which need a high degree of
concentration, such as driving.
If you forget to take Daloxy
If you take a smaller dose of Daloxy than prescribed, or if 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 usual schedule.
If the interval to the next dose is shorter, take the prolonged-release capsules, but postpone the next dose by
8 hours.
As a matter of principle, you should never take Daloxy more frequently than at 8-hourly intervals.
If you stop taking Daloxy
Do not stop taking Daloxy without consulting your doctor.

If treatment with Daloxy is no longer necessary, you are advised to reduce the daily dosage gradually. If you
stop the treatment abruptly, you may suffer withdrawal symptoms e.g. agitation, palpitations, shaking and
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
