What Ormetone is and what it is used for

Ormetone is a prolonged-release tablet, which means that its active substances are released
over an extended period. Their action lasts for 12 hours.
Pain relief
You have been prescribed Ormetone for the treatment of severe pain, which can be
adequately managed only with opioid analgesics. Naloxone is added to counteract
How Ormetone works in pain relief
Ormetone tablets contain oxycodone and naloxone as active substances. Oxycodone is
responsible for the pain relieving effect of Ormetone. It is a strong analgesic (“painkiller”)
that belongs to a group of medicines called opioids. Naloxone is intended to counteract
constipation. Constipation is a typical side effect of treatment with opioid painkillers.

What you need to know before you take Ormetone

Do NOT take Ormetone tablets
• if you are allergic to oxycodone or naloxone or any of the other ingredients
of this medicine (listed in section 6),
• if you have breathing problems, such as breathing more slowly or weakly than
expected (respiratory depression),
• if you suffer from a severe lung disease associated with narrowing of the airways
(chronic obstructive pulmonary disease or COPD),
• if you suffer from a condition known as cor pulmonale. In this condition the right
side of the heart becomes enlarged, due to increased pressure inside blood vessels

in the lung etc. (e.g. as a result of COPD – see above),
• if you suffer from severe bronchial asthma,
• if you have a type of bowel obstruction (paralytic ileus) not caused by opioids,
• if you have moderate to severe liver problems.
Warnings and Precautions
Talk to your doctor or pharmacist before taking Ormetone:

in the case of elderly or debilitated (weak) patients,
if you have a type of bowel obstruction (paralytic ileus) caused by opioids,
if you have kidney problems,
if you have mild liver problems,
if you have severe lung problems (i.e. reduced breathing capacity),
if you suffer with a condition characterised by frequent breathing stops during the
night, which may make you feel very sleepy during the daytime (sleep apnoea),
if you have myxoedema (a thyroid disorder, with dryness, coldness and swelling
[‘puffiness’] of the skin, affecting the face and limbs),
if your thyroid gland is not producing enough hormones (underactive thyroid, or
if your adrenal glands are not producing enough hormones (adrenal insufficiency, or
Addison’s disease),
if you have a mental illness accompanied by a (partial) loss of reality (psychosis),
due to alcohol or intoxication with other substances (substance-induced psychosis),
if you suffer from gallstone problems,
if your prostate gland is abnormally enlarged (prostate hypertrophy),
if you are or ever have been addicted to alcohol or drugs, or have previously suffered
from withdrawal symptoms such as agitation, anxiety, shaking or sweating upon
stopping alcohol or drugs (delirium tremens),
if your pancreas is inflamed (pancreatitis),
if you have low blood pressure (hypotension),
if you have high blood pressure (hypertension),
if you have pre-existing heart disease,
if you have a head injury (due to the risk of increased brain pressure),
if you suffer from epilepsy or are prone to fits,
if you are also taking a type of medicine known as a MAO inhibitor (used to treat
depression or Parkinson’s disease), e.g. medicines containing tranylcypromine,
phenelzine, isocarboxazid, moclobemide and linezolid.
if sleepiness or episodes of suddenly falling asleep occur.

Tell your doctor if any of the above has ever applied to you in the past. Also, please tell your
doctor if you develop any of the above disorders while you are taking Ormetone.
These tablets are not recommended for use in patients with advanced digestive or pelvic
cancers where bowel obstruction may be a problem.
Children and adolescents
This medicine must not be given to children or adolescents under 18 years of age as the
safety and benefits have not been shown yet.
How to use Ormetone correctly


If you experience severe diarrhoea at the start of treatment (within the first 3-5 days) this
may be due to the effect of naloxone. It may be a sign that your bowel movements are
returning to normal. If diarrhoea persists after 3-5 days, or it gives you cause for concern,
please contact your doctor.
If you have been using high doses of another opioid, withdrawal symptoms (such as
restlessness, bouts of sweating or muscle pain) may occur when you initially switch to
taking these tablets. If you experience withdrawal symptoms, you may need to be specially
monitored by your doctor.
If you need to undergo surgery, please tell your doctor that you are taking this medicine.
If you have been taking this medicine for a long time, you may become tolerant. This means
you may need a higher dose to achieve the desired effect. Long-term use of these tablets
may also lead to physical dependence. Medicines containing oxycodone should be avoided
in patients with a present or past abuse of alcohol, drugs or medicines. Withdrawal
symptoms may occur if treatment is stopped too suddenly. If you no longer need treatment,
you should reduce your daily dose gradually, in consultation with your doctor.
As with other strong opioid painkillers, there is a risk that you may develop a
psychological dependence to oxycodone.
You may notice remains of the tablet in your stools. Do not be alarmed, as the active
substances will have already been released in the stomach and gut, and absorbed into your
Incorrect use of Ormetone
Ormetone is not suitable for withdrawal treatment.
This medicine should never be abused, particularly if you have a drug addiction. If you are
addicted to drugs such as heroin, morphine or methadone, severe withdrawal symptoms are
likely if you abuse this medicine because it contains the ingredient naloxone. Pre-existing
withdrawal symptoms may be made worse.
You should never misuse the tablets by dissolving and injecting them (e.g. into a blood
vessel). They contain talc, which can cause destruction of local tissue (necrosis) and
changes in lung tissue (lung granuloma). Misuse can also have other serious consequences
which may be fatal.
Other medicines and Ormetone
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
The risk of side effects is increased if you take these tablets at the same time as medicines
which affect the way the brain works. For example, you may feel very sleepy, or breathing
problems (slow and shallow breathing) may get worse.
Examples of medicines that affect the way the brain works include:

other strong painkillers (opioids),

sleep medication and tranquilisers (sedatives, hypnotics),


medicines used to treat allergies, travel sickness or nausea (antihistamines or

other medicines which act on the nervous system (phenothiazines, neuroleptics).

Tell your doctor if you are taking:

medicines that decrease the blood’s clotting ability (coumarin derivatives), this
clotting time may be speeded up or slowed down

antibiotics of the macrolide type (such as clarithromycin)

antifungal medicines of the –azole type (e.g. ketoconazole)

ritonavir or other protease inhibitors (used to treat HIV)

rifampicin (used to treat tuberculosis)

carbamazepine (used to treat seizures, fits or convulsions and certain pain conditions)

phenytoin (used to treat seizures, fits or convulsions).
Ormetone with food, drink and alcohol
Drinking alcohol whilst taking Ormetone 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 are taking
You should avoid drinking grapefruit juice while you are taking this medicine.
Pregnancy and breast-feeding
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a
baby, ask your doctor or pharmacist for advice before taking this medicine.
Use of Ormetone during pregnancy should be avoided unless your doctor finds treatment
with this medicine is essential. If used over prolonged periods during pregnancy,
oxycodone may lead to withdrawal symptoms in the new born baby. If oxycodone is
given during childbirth, the baby may have breathing problems such as slow and shallow
breathing (respiratory depression).
Breast-feeding should be stopped during treatment with this medicine as oxycodone (one
of the active substances of this medicine) passes into breast milk and it is not known
whether naloxone also passes into breast milk. Therefore, a risk for the breastfed infant
cannot be excluded in particular following intake of multiple doses of this medicine.
Driving and using machines
This medicine can affect your ability to drive or operate machines as it may make you
sleepy or dizzy. This is most likely at the start of your treatment, after a dose increase or
after switching from a different medication. These side effects should disappear once you
are on a stable dose.
This medicine has been associated with sleepiness and episodes of suddenly falling
asleep. If you experience these side effects, you must not drive or operate machinery.
You should tell your doctor if this occurs.

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while
taking this medicine.
Ormetone contains lactose
Ormetone 10 mg/5 mg contains lactose (milk sugar). If you have been told by your doctor
that you have an intolerance to some sugars, contact your doctor before taking Ormetone 10
mg/5 mg.

How to take Ormetone

Always take this medicine exactly as your doctor has told you. Check with your doctor
or pharmacist if you are not sure.
You must swallow the prolonged-release tablet whole, so as not to affect the slow release of
oxycodone from the tablet. Do not break, chew or crush the prolonged-release tablets.
Taking broken, chewed or crushed tablets may result in your body absorbing a potentially
fatal dose of oxycodone (see under “If you take more Ormetone than you should”).
Unless otherwise prescribed by your doctor, the usual dose is:
To treat pain
The usual starting dose is one Ormetone 10 mg/5 mg prolonged-release tablet every 12
Your doctor will decide how much you should to take every day and how to divide the
total daily dose into morning and evening doses. The doctor will also decide on any
necessary dose adjustment during treatment depending on your level of pain and
individual sensitivity. You should be given the lowest dose needed for pain relief. If you
have already been treated with opioids, your treatment with this medicine may be started
at a higher dose.
The maximum daily dose is 160 mg oxycodone hydrochloride and 80 mg naloxone
hydrochloride. If you need a higher dose, your doctor may give you additional oxycodone
without naloxone. However, the maximum daily dose of oxycodone should not exceed
400 mg. The beneficial effect of naloxone on bowel movements may be affected if
additional oxycodone is given without additional naloxone.
If you experience pain between doses of Ormetone, you may need to take an additional fastacting painkiller. Ormetone is not suitable for this. Please talk to your doctor.
If you feel that these tablets are too strong or too weak, please talk to your doctor or
Elderly patients
In general, no dose adjustment is necessary for elderly patients with normal kidney and/or
liver function.

Liver or kidney problems
If you have kidney or mild liver problems your doctor will prescribe Ormetone with
special caution. You must not take these tablets if you have moderate or severe liver
problems (see also Section 2 “Do not take Ormetone tablets” and “Warnings and
