pregnant women. Oxycodone crosses the placenta into the organism of the child. Prolonged use of oxycodone during pregnancy can cause withdrawal symptoms in newborns. Use of oxycodone during delivery can cause respiratory depression in the newborn. Breast-feeding You should not use Onexila XL when you are breast-feeding. Oxycodone passes into breast milk. Therefore, a risk for the sucking infant cannot be excluded in particular following intake of multiple doses of Onexila XL. Driving and using machines Oxycodone impairs alertness and reactivity to such an extent that the ability to drive and operate machinery is affected or ceases altogether. In these circumstances Onexila XL has moderate to major influence on the ability to drive and use machines. With stable therapy, a general ban on driving a vehicle may be not necessary. In these circumstances Onexila XL has minor influence on the ability to drive and use machines. The treating physician must assess the individual situation. Please discuss with your doctor whether or under what conditions you can drive a vehicle. To look at the possible side effects affecting the motor skills and concentration see section 4. "Possible side effects". Onexila XL contains sucrose This medicinal product contains sucrose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before you take this medicinal product.
Onexila XL Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. The recommended dose is Adults and adolescents (≥12 years of age) The usual initial dose is 10 mg of oxycodone hydrochloride once daily, preferably taken at the same time each day. Some patients may benefit from a starting dose of 5 mg to minimise the incidence of side effects. For doses not realisable/practicable with this medicinal product other strengths and medicinal products are available. Further determination of the daily dose and any dose adjustments during the further course of therapy are performed by the treating physician and depend on the previous dosage. Dose adjustments should be made in steps of approximately one third of the daily dose to reduce the risk of possibly occurring side effects. In general, the lowest effective dose for the relief of pain should be chosen. Patients who have already taken opioids can start treatment with higher dosages taking into account their experience with opioid treatment. Some patients who receive Onexila XL need rapidly acting painkillers as rescue medication to control breakthrough pain. Onexila XL is not intended for the treatment of breakthrough pain. For the treatment of non-cancer pain a daily dose of 40 mg of oxycodone hydrochloride is generally sufficient, but higher dosages may be necessary. Patients with cancer pain usually require dosages from 80 to 120 mg of oxycodone hydrochloride which may be increased up to 400 mg in individual cases. The treatment needs to be controlled regularly with regard to pain relief and other effects in order to achieve the best pain therapy possible as well as to be able to treat any occurring side effects in good time and to decide whether treatment should be continued. Your doctor will adjust the dosage depending on the pain intensity and how you respond to the treatment (see also section 2, "Warnings and precautions"). Risk patients If you have impaired kidney and/or liver function or if you have a low body weight your doctor may prescribe a lower starting dose. Use in children under 12 years of age Onexila XL should not be used in children under 12 years of age because of safety and efficacy concerns. Method of administration Onexila XL is for oral use only. Take the tablets once daily as advised by your doctor. Swallow the prolonged-release tablets whole with a sufficient amount of liquid (1⁄2 glass of water) with or without food, preferably at the same time each day. The prolonged-release tablets must be swallowed whole, not chewed or crushed (see also section 2, "Warnings and precautions"). Opening instruction for the blister This medicinal product is packed in a child-resistant blister. You cannot press out the prolonged-release tablets through the blister. Please observe the following opening instruction for the blister: 1. Tear off a single dose along the perforation line of the blister. 2. Hereby an unsealed area is accessible which is located at the position, where the perforation lines have crossed. 3. Pull at the unsealed "strap" to peel off the cover seal. If you take more Onexila XL than you should If you have taken more Onexila XL as prescribed you should inform your doctor or your local poison control centre immediately. The following symptoms may occur: constricted pupils (miosis), depressed breathing (respiratory depression), sleepiness, skeletal muscle flaccidity and drop in blood pressure. In severe cases circulatory collapse, drowsiness, unconsciousness (coma), slowing of the heart rate (bradycardia) and accumulation of water in the lungs (non-cardiogenic lung oedema) may occur; abuse of high doses of strong opioids such as oxycodone can be fatal. In no case you should expose yourself to situations requiring elevated concentration e.g. driving a car. If you forget to take Onexila XL If you miss the intake of Onexila XL, pain relief will consequently be insufficient or cease altogether. You can make up for a forgotten dose if the next regular intake is not due for at least another 12 hours. You can then continue to take Onexila XL as directed. Do not take a double dose to make up for a forgotten dose. If you stop taking Onexila XL Do not stop treatment without informing your doctor. When a patient no longer requires therapy with Onexila XL, it may be advisable to taper the dose gradually to prevent symptoms of withdrawal. A withdrawal syndrome may occur upon abrupt cessation of therapy. For symptoms of the withdrawal syndrome see section 4 "Possible side effects". If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them. Significant side effects or signs to consider and measures to be taken when these side effects or signs occur If you experience any of the following side effects, stop taking Onexila XL and contact your doctor immediately. Depressed breathing (slowed breathing) is the most significant risk induced by opioids and is most likely to occur in elderly or debilitated patients. As a consequence, in predisposed patients opioids can cause severe drops in blood pressure. Apart from this oxycodone can cause constricted pupils, bronchial spasms and spasms in smooth muscles and suppress the cough reflex. Other possible side effects Very common (may affect more than 1 in 10 people)
Uncommon (may affect up to 1 in 100 people)
dry skin, herpes simplex (disorder of the skin and mucosa) blood in urine (haematuria) absence of menstrual bleeding (amenorrhoea) changes in body weight (loss or rise), cellulitis
Very rare (may affect up to 1 in 10,000 people)

This leaflet was last revised in 07/2016
Onexila XL 10mg prolonged-release tablets comes as tablet containing 10mg. Always follow the dose your doctor or pharmacist has given you, and read the leaflet that comes with the medicine.
The active substance in Onexila XL 10mg prolonged-release tablets is oxycodone hydrochloride.
Medicines with the same active substance, strength and form include: Ixyldone 10 mg prolonged-release tablets, Longtec 10 mg Prolonged Release Tablets, Oxeltra 10 mg Prolonged-Release Tablets. In total there are 6 equivalent products. They are interchangeable only if your prescriber or pharmacist says so.
This leaflet reproduces the patient information leaflet approved for Onexila XL 10mg prolonged-release tablets, as published on the electronic medicines compendium (emc). The version printed inside your medicine’s packaging is the one that applies to you.
Whether a medicine is available over the counter or on prescription only depends on its licence. Check the leaflet, or ask your pharmacist — they can tell you straight away.

Severe pain, which can be adequately managed only with opioid analgesics.
Onexila XL is indicated in adults, and adolescents aged 12 years and older.
Posology
The dosage depends on the intensity of pain and the patient's individual susceptibility to the treatment.
The following general dosage recommendations apply:
Adults and adolescents (≥12 years)
Dose titration
In general, the initial dose for opioid naïve patients is 10 mg oxycodone hydrochloride given once daily. Some patients may benefit from a starting dose of 5 mg to minimise the incidence of adverse reactions. For the lower starting dose other medicinal products with more appropriate strengths are available.
Patients already receiving opioids may start treatment with higher dosages taking into account their experience with former opioid therapies.
For doses not realisable/practicable with this medicinal product, other strengths and medicinal products are available.
According to well-controlled clinical studies 10-13 mg oxycodone hydrochloride correspond to approximately 20 mg morphine sulphate, both in the prolonged-release formulation.
Because of individual differences in sensitivity for different opioids, it is recommended that patients should start conservatively with Onexila XL after conversion from other opioids, with 50-75% of the calculated oxycodone dose.
Dose adjustment
Some patients who take Onexila XL need rapid release analgesics as rescue medication in order to control breakthrough pain. Onexila XL is not indicated for the treatment of acute pain and/or breakthrough pain. The single dose of the rescue medication should amount to 1/6 of the equianalgesic daily dose of Onexila XL. Use of the rescue medication more than twice daily indicates that the dose of Onexila XL needs to be increased. The dose should not be adjusted more often than once every 1-2 days until a stable once daily administration has been achieved.
Following a dose increase from 10 mg to 20 mg taken once daily, dose adjustments should be made in steps of approximately one third of the daily dose. The aim is a patient specific dosage which, with once daily administration, allows for adequate analgesia with tolerable undesirable effects and as little rescue medication as possible as long as pain therapy is needed.
In general, the lowest effective analgesic dose should be chosen. For the treatment of non malignant pain a daily dose of 40 mg is generally sufficient; but higher dosages may be necessary. Patients with cancer-related pain may require dosages of 80 to 120 mg, which in individual cases can be increased to up to 400 mg. If even higher doses are required, the dose should be decided individually balancing efficacy with the tolerance and risk of undesirable effects.
Duration of administration
Onexila XL should not be taken longer than necessary. If long-term treatment is necessary due to the type and severity of the illness careful and regular monitoring is required to determine whether and to what extent treatment should be continued. If opioid therapy is no longer indicated it may be advisable to reduce the daily dose gradually in order to prevent symptoms of a withdrawal syndrome.
Elderly patients
Elderly patients without clinical manifestation of impaired liver and/or kidney function usually do not require dose adjustments.
Risk patients
Risk patients, for example patients with impaired renal or hepatic function, low body weight or slow metabolism of medicinal products, should initially receive half the recommended adult dose if they are opioid naïve. Therefore the lowest recommended dosage, i.e. 10 mg, may not be suitable as a starting dose. Dose titration should be performed in accordance with the individual clinical situation.
Paediatric population
Children under 12 years of age
Onexila XL should not be used in children under 12 years of age because of safety and efficacy concerns.
Method of administration
For oral use.
Onexila XL should be taken once daily at the dosage determined.
The prolonged-release tablets may be taken with or independent of meals with a sufficient amount of liquid. Onexila XL must be swallowed whole, not chewed or crushed.
- Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
- Severe respiratory depression with hypoxia and/or hypercapnia.
- Severe chronic obstructive pulmonary disease.
- Cor pulmonale.
- Severe bronchial asthma.
- Paralytic ileus.
- Acute abdomen, delayed gastric emptying.
Caution is required in
- elderly or debilitated patients,
- patients with severe impairment of lung, hepatic or renal function,
- myxoedema, hypothyroidism,
- Addison's disease (adrenal insufficiency),
- intoxication psychosis (e.g. alcohol),
- prostatic hypertrophy,
- alcoholism, known opioid dependence,
- delirium tremens,
- pancreatitis,
- diseases of the biliary tract,
- biliary or ureteric colic,
- conditions with increased brain pressure,
- disturbances of circulatory regulation,
- epilepsy or seizure tendency,
- patients taking MAO inhibitors.
In suspicion or in case of paralytic ileus administration of Onexila XL has to be stopped immediately.
Surgical procedures
Special care should be taken when oxycodone is applied in patients undergoing bowel-surgery. Opioids should only be administered post-operatively when the bowel function has been restored.
The safety of Onexila XL used pre-operatively has not been established and cannot be recommended.
Respiratory and cardiac depression
Respiratory depression is the most significant risk induced by opioids and is most likely to occur in elderly or debilitated patients. The respiratory depressant effect of oxycodone can lead to increased carbon dioxide concentrations in blood and hence in cerebrospinal fluid. In predisposed patients opioids can cause severe decrease in blood pressure.
Tolerance and dependence
Long-term use of oxycodone can cause the development of tolerance which leads to the use of higher doses in order to achieve the desired analgesic effect. There is a cross-tolerance to other opioids. Chronic use of oxycodone can cause physical dependence. Withdrawal symptoms may occur following abrupt discontinuation of therapy. If therapy with oxycodone is no longer required it may be advisable to reduce the daily dose gradually in order to avoid the occurrence of a withdrawal syndrome.
Oxycodone has a primary dependence potential. However, when used as directed in patients with chronic pain the risk of developing physical or psychological dependence is markedly reduced or needs to be assessed in a differentiated manner. There are no data available on the actual incidence of psychological dependence in chronic pain patients. In patients with a history of alcohol and drug abuse the medicinal product must be prescribed with special care.
Abuse
In case of abusive parenteral venous injection the tablet excipients may lead to necrosis of the local tissue, granulomas of the lung or other serious, potentially fatal events. To avoid damage to the controlled release properties of the tablets the prolonged-release tablets must not be chewed or crushed. The administration of chewed or crushed tablets leads to rapid release and absorption of a potentially fatal dose of oxycodone (see section 4.9).
Alcohol
Concomitant use of alcohol and Onexila XL may increase the undesirable effects of Onexila XL; concomitant use should be avoided.
Special patient groups
Patients with severe hepatic impairment should be closely monitored.
Paediatric population
The safety and efficacy of Onexila XL in children aged 12 years and younger have not been established. Onexila XL should not be used in children aged 12 years and younger because of safety and efficacy concerns.
Anti-doping warning
Athletes must be aware that this medicine may cause a positive reaction to 'anti-doping' tests.
Use of Onexila XL as a doping agent may become a health hazard.
Excipients
This medicinal product contains sucrose. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.
• Central nervous system depressants (e.g. sedatives, hypnotics, phenothiazines, neuroleptics, anaesthetics, antidepressants, muscle relaxants, antihistamines, antiemetics) and other opioids or alcohol can enhance the adverse reactions of oxycodone, in particular respiratory depression.
• Anticholinergics (e.g. neuroleptics, antihistamines, antiemetics, antiparkinson medicinal products) can enhance the anticholinergic undesirable effects of oxycodone (such as constipation, dry mouth or micturition disorders).
• Cimetidine and inhibitors of cytochrome P450-3A such as ketoconazole, variconazole and erythromycin may inhibit the metabolism of oxycodone.
• Monoaminooxidase (MAO) inhibitors are known to interact with narcotic analgesics, producing CNS excitation or depression with hyper- or hypotensive crisis (see section 4.4).
• The inhibition of cytochrome P450 2D6 and 3A4 has no clinical relevance, however, strong CYP2D6 inhibitors may have an effect on the elimination of oxycodone. The effect of other relevant isoenzyme inhibitors on the metabolism of oxycodone is not known. Potential interactions should be taken into account.
• Clinically relevant changes in International Normalised Ratio (INR) in both directions have been observed in individuals if coumarin anticoagulants are co-applied with oxycodone.
• Alcohol may enhance the pharmacodynamic effects of Onexila XL; concomitant use should be avoided.
There are no studies investigating the effect of oxycodone on CYP catalysed metabolism of other active substances.
Use of this medicinal product should be avoided to the extent possible in patients who are pregnant or lactating.
Pregnancy
There are limited data from the use of oxycodone in pregnant women. Infants born to mothers who have received opioids during the last 3 to 4 weeks before giving birth should be monitored for respiratory depression. Withdrawal symptoms may be observed in the newborn of mothers undergoing treatment with oxycodone
Breastfeeding
Oxycodone may be secreted in breast milk and may cause respiratory depression in the newborn. Oxycodone should, therefore, not be used in breastfeeding mothers.
Fertility
Animal toxicology studies have not shown any effects on fertility (see section 5.3).
Oxycodone can impair alertness and reactivity to such an extent that the ability to drive and operate machinery is affected or ceases altogether. In these circumstances Onexila XL has moderate to major influence on the ability to drive and use machines.
With stable therapy, a general ban on driving a vehicle is not necessary. In these circumstances Onexila XL has minor influence on the ability to drive and use machines. The treating physician must assess the individual situation.
Summary of the safety profile
Oxycodone can cause respiratory depression, miosis, bronchial spasms and spasms of the smooth muscles and can suppress the cough reflex. Tolerance and dependence may occur (see below).
The most serious adverse reaction, as with other opioids, is respiratory depression (see section 4.9). This is most likely to occur in elderly, debilitated or opioid-intolerant patients. In predisposed patients opioids can cause severe drop in blood pressure.

Description of selected adverse reactions
Tolerance and dependence may develop with chronic use and a withdrawal syndrome may occur upon abrupt cessation of therapy. The opioid abstinence or withdrawal syndrome is characterised by some or all of the following: restlessness, lacrimation, rhinorrhoea, yawning, perspiration, chills, myalgia, mydriasis and palpitations. Other symptoms also may develop, including: irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhoea, or increased blood pressure, respiratory rate or heart rate.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme. Website: www.mhra.gov.uk/yellowcard.
Symptoms
Miosis, respiratory depression, somnolence, reduced skeletal muscle tone and drop in blood pressure. In severe cases circulatory collapse, stupor, coma, bradycardia and non-cardiogenic lung oedema may occur; abuse of high doses of strong opioids such as oxycodone can be fatal.
Management
Primary attention should be given to the establishment of a patent airway and institution of assisted or controlled ventilation.
In the event of overdosing intravenous administration of an opiate antagonist (e.g. 0.4-2 mg intravenous naloxone) may be indicated. Administration of single doses must be repeated depending on the clinical situation at intervals of 2 to 3 minutes. Intravenous infusion of 2 mg of naloxone in 500 ml isotonic saline or 5% dextrose solution (corresponding to 0.004 mg naloxone/ml) is possible. The rate of infusion should be adjusted to the previous bolus injections and the response of the patient.
Gastric lavage can be taken into consideration. Consider activated charcoal (50 g for adults, 10 -15 g for children), if a substantial amount has been ingested within 1 hour, provided the airway can be protected. It may be reasonable to assume that late administration of activated charcoal may be beneficial for prolonged-release preparations; however there is no evidence to support this.
For speeding up the passage a suitable laxative (e.g. a PEG based solution) may be useful.
Supportive measures (artificial respiration, oxygen supply, administration of vasopressors and infusion therapy) should, if necessary, be applied in the treatment of accompanying circulatory shock. Upon cardiac arrest or cardiac arrhythmias cardiac massage or defibrillation may be indicated. If necessary, assisted ventilation as well as maintenance of water and electrolyte balance.
