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

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
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
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 medicines.
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

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 Ormetone.
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 5 mg/2.5 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 5 mg/2.5 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
fast-acting 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

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
