1. What Oxyduo is and what it is used for

Oxyduo is a prolonged-release tablet, meaning that the active substances are released over an extended period. Its effect lasts for 12 hours.
These tablets may only be used in adults.

Pain relief
Oxyduo is indicated for the treatment of severe pain that can only be adequately managed with opioid analgesics. Naloxone hydrochloride counteracts constipation.

How Oxyduo works in pain relief
Oxyduo contains two active substances: oxycodone hydrochloride and naloxone hydrochloride.
Oxycodone hydrochloride is responsible for the analgesic effect of Oxyduo and is a potent opioid analgesic.
The second active substance in Oxyduo, naloxone hydrochloride, helps prevent constipation.
Gastrointestinal disturbances (e.g. constipation) are typical side effects of opioid analgesic therapy.

Restless legs syndrome
Oxyduo has been prescribed for the symptomatic second-line treatment of moderate to very severe restless legs syndrome in patients who cannot be treated with dopaminergic medicinal products.
Patients with restless legs syndrome experience unpleasant sensations in the limbs. These sensations may occur when sitting or lying down and are relieved only by an irresistible urge to move the legs, sometimes the arms or other parts of the body. This makes sitting still and falling asleep very difficult. Naloxone hydrochloride counteracts constipation.

How Oxyduo works in restless legs syndrome
These tablets help to alleviate the unpleasant sensations, thereby reducing the need to move the limbs. The second active substance in Oxyduo, naloxone hydrochloride, is intended to counteract constipation. Gastrointestinal disturbances (e.g. constipation) are typical side effects of opioid therapy.

2. Important information before using Oxyduo

When not to use Oxyduo

  • if the patient is allergic to oxycodone hydrochloride, naloxone hydrochloride, or any of the other ingredients of this medicine (listed in section 6),
  • if the patient has breathing problems that prevent sufficient oxygen from entering the blood and carbon dioxide from being removed from the body (respiratory depression),
  • if the patient has severe lung disease associated with airway obstruction (chronic obstructive pulmonary disease, COPD),
  • if the patient has been diagnosed with cor pulmonale. In this condition, the right side of the heart is enlarged due to increased pressure in the blood vessels of the lungs (e.g. as a result of COPD - see above),
  • if the patient has been diagnosed with severe bronchial asthma,
  • if the patient has paralytic ileus (a type of intestinal obstruction) not caused by opioids,
  • if the patient has moderate to severe liver function impairment.

Additionally, in restless legs syndrome

  • if the patient has a history of opioid drug dependence.

Warnings and precautions
Before starting Oxyduo, consult a doctor or pharmacist:

  • in elderly and debilitated patients,
  • if the patient has opioid-induced paralytic ileus (a type of intestinal obstruction),
  • if the patient has kidney function disorders,
  • if the patient has mild liver function impairment,
  • if the patient has severe lung function disorders (i.e. reduced vital capacity),
  • if the patient has a condition characterised by frequent breathing pauses during the night, which may cause daytime sleepiness (sleep apnoea),
  • if the patient has myxoedema (a thyroid disorder presenting with dryness, lowered body temperature, and skin swelling ["puffy face"], affecting the face and limbs),
  • if the thyroid gland does not produce sufficient hormones (underactive thyroid or hypothyroidism),
  • if the adrenal glands do not produce sufficient hormones (adrenal insufficiency or Addison's disease),
  • if the patient has a mental disorder with accompanying (partial) loss of reality perception (psychosis) caused by alcohol or other substances (substances causing psychosis),
  • if the patient has symptoms related to gallstones or any other disorders of the biliary tract (biliary tract disease, gallbladder disease, etc.),
  • if the patient has been diagnosed with abnormal enlargement of the prostate gland (prostate enlargement),
  • if the patient suffers from alcoholism or delirium tremens,
  • if the patient has pancreatitis,
  • if the patient has low blood pressure (hypotension),
  • if the patient has high blood pressure (hypertension),
  • if the patient has a previously diagnosed cardiovascular disease,
  • if the patient has a head injury (due to the risk of increased intracranial pressure),
  • if the patient has epilepsy or a tendency to seizures,
  • if the patient is currently taking or has taken monoamine oxidase inhibitors (MAOIs) within the past two weeks (used to treat depression or Parkinson's disease), e.g. medicines containing tranylcypromine, phenelzine, isocarboxazid, moclobemide, and linezolid,
  • if the patient experiences drowsiness or episodes of sudden sleep.

Contact a doctor if the patient develops severe upper abdominal pain, possibly radiating to the back, nausea, vomiting, or fever, as these may be symptoms related to pancreatitis and biliary tract disorders.
Sleep-related breathing disorders
Oxyduo may cause breathing disorders during sleep, such as sleep apnoea (pauses in breathing during sleep) and nocturnal hypoxaemia (low oxygen levels in the blood). Symptoms may include breathing pauses during sleep, waking up at night due to breathlessness, difficulty maintaining sleep, or excessive daytime sleepiness. If the patient or another person notices such symptoms, contact a doctor. The doctor may consider reducing the dose.
Consult a doctor if any of the above conditions applied to the patient in the past.
Consult a doctor also if any of the above disorders develop during treatment with Oxyduo. The most serious consequence of opioid painkiller overdose is respiratory depression (slow and shallow breathing). This may lead, among other things, to reduced oxygen levels in the blood, resulting in fainting.
Diarrhoea
If severe diarrhoea occurs at the beginning of treatment, it may be due to the action of naloxone. This may indicate that intestinal function is returning to normal. Such diarrhoea may occur within the first 3–5 days of treatment. If diarrhoea persists beyond 3–5 days or is bothersome to the patient, the patient should contact a doctor.
Switching to Oxyduo
When switching to Oxyduo after long-term use of another opioid medicine, withdrawal symptoms such as restlessness, especially motor restlessness, excessive sweating, and muscle pain may initially occur. If the patient experiences such symptoms, special medical supervision may be necessary.
Tolerance, drug dependence, and addiction
This medicine contains oxycodone, which is an opioid. It may cause dependence and/or addiction.
This medicine contains oxycodone, an opioid painkiller. Repeated use of opioid painkillers may lead to reduced effectiveness of the medicine (the patient becomes accustomed, known as tolerance). Repeated use of Oxyduo may lead to dependence and abuse, which may result in life-threatening overdose. The risk of these adverse effects may increase with higher doses and longer duration of use.
Dependence or abuse may cause the patient to feel they have lost control over the dose or frequency of medicine intake. The patient may feel they must continue taking the medicine, even if it does not help relieve pain.
The risk of drug dependence or addiction varies between patients. The risk of dependence on Oxyduo may be higher if:

  • the patient or anyone in the family has ever abused or been dependent on alcohol, prescription medicines, or drugs;
  • the patient smokes cigarettes;
  • the patient has had mood problems (depression, anxiety, or personality disorders) or has been treated by a psychiatrist for other mental disorders.

If, while taking Oxyduo, the patient notices any of the following symptoms, it may indicate developing tolerance to the medicine or addiction:

  • the patient needs to take the medicine longer than prescribed by the doctor;
  • the patient must take a higher dose than recommended;
  • the patient uses the medicine for reasons other than those prescribed by the doctor, e.g. "to stay calm" or "to help sleep";
  • the patient has made repeated, unsuccessful attempts to discontinue or control medicine use;
  • the patient feels unwell after stopping the medicine and feels better after resuming it ("withdrawal effects").

If any of these symptoms are observed, contact a doctor to discuss the best treatment path for the patient, including when to stop taking the medicine and how to discontinue treatment safely (see section 3 "Stopping Oxyduo treatment").
Advanced gastrointestinal or pelvic cancer
Inform the doctor if the patient has advanced gastrointestinal or pelvic cancer, where intestinal obstruction may be a problem.
Surgery
If the patient is to undergo surgery, they should inform the doctors about taking Oxyduo.
Effect on hormone production
Like other opioids, oxycodone may affect normal hormone production in the body, such as cortisol or sex hormones, especially if the patient has taken high doses for a prolonged period. If the patient develops persistent symptoms such as nausea or vomiting, loss of appetite, fatigue, weakness, dizziness, changes in menstrual cycle, impotence, infertility, or reduced sex drive, discuss with a doctor, who may order hormone level monitoring.
Hyperalgesia
This medicine may increase sensitivity to pain, particularly at high doses. Inform the doctor if this occurs. Dose reduction or a change in medicine may be necessary.
Residue in stool
The patient may notice remnants of the prolonged-release tablet in the stool. Do not be alarmed, as the active substances (oxycodone hydrochloride and naloxone hydrochloride) have already been released in the stomach and intestines and absorbed by the body.
Improper use of Oxyduo
Oxyduo is not suitable for treating withdrawal symptoms.
Oxyduo 5 mg + 2.5 mg
Prolonged-release tablets must be swallowed whole; they must not be divided, broken, chewed, or crushed. Taking a divided, broken, chewed, or crushed tablet may lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking a higher than recommended dose of Oxyduo").
Oxyduo 10 mg + 5 mg, 20 mg + 10 mg, 40 mg + 20 mg
Prolonged-release tablets may be divided into equal doses but must not be chewed or crushed. Taking chewed or crushed tablets may lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking a higher than recommended dose of Oxyduo").
Abuse
Never abuse Oxyduo, especially in cases of drug dependence. In individuals dependent on substances such as heroin, morphine, or methadone, abusing Oxyduo may cause severe withdrawal symptoms, as Oxyduo contains naloxone as an ingredient. Existing withdrawal symptoms may worsen.
Improper use
Do not misuse Oxyduo by dissolving and injecting the tablet contents (e.g. into blood vessels). The tablets contain, in particular, talc, which may cause local tissue necrosis and lung tissue changes (pulmonary granulomas). Such abuse may also lead to other serious consequences, even death.
Doping
Using Oxyduo may result in a positive doping test. Using Oxyduo as a stimulant may pose a health risk.
Oxyduo and other medicines
Inform the doctor or pharmacist about all medicines currently or recently taken, as well as any medicines the patient plans to take.
The risk of adverse effects increases if the patient takes antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medicines may interact with oxycodone, causing symptoms such as involuntary, rhythmic muscle contractions, including muscles controlling eye movements, agitation, excessive sweating, tremor, increased reflexes, increased muscle tension, and body temperature above 38°C. If these symptoms occur, contact a doctor.
Concurrent use of opioids, including oxycodone hydrochloride, and sedative medicines such as benzodiazepines or other similar medicines, increases the risk of drowsiness, breathing difficulties (respiratory depression), coma, and may be life-threatening. Therefore, concurrent use should only be considered if other treatment options are not possible.
If the doctor prescribes Oxyduo together with sedative medicines, they should limit the dose and duration of combined treatment.
Inform the doctor about all sedative medicines taken and strictly follow the doctor's dosing instructions. It may be helpful to inform friends or relatives so they are aware of the above symptoms. If such symptoms occur, contact a doctor. Examples of these sedatives or similar medicines include:

  • other strong painkillers (opioid painkillers),
  • medicines used to treat epilepsy, pain, and anxiety, such as gabapentin and pregabalin,
  • sleeping and calming medicines (including benzodiazepines, anxiolytics),
  • antidepressants,
  • medicines used to treat allergies, motion sickness, or nausea (antihistamines or antiemetics),
  • medicines used to treat psychiatric or mental disorders (antipsychotics, including phenothiazines and neuroleptics).

When taking these tablets at the same time as other medicines, the effect of these tablets or the other medicine, as described below, may change. Inform the doctor if the patient is taking:

  • medicines that reduce blood clotting (coumarin derivatives), which may prolong or shorten blood clotting time,
  • macrolide antibiotics (e.g. clarithromycin, erythromycin, or telithromycin),
  • azole antifungal medicines (e.g. ketoconazole, voriconazole, itraconazole, and posaconazole),
  • specific medicines called protease inhibitors, used to treat HIV (e.g. ritonavir, indinavir, nelfinavir, saquinavir),
  • cimetidine (used to treat stomach ulcers, indigestion, or heartburn),
  • rifampicin (used to treat tuberculosis),
  • carbamazepine (used to treat epilepsy, seizures, or certain types of pain),
  • phenytoin (used to treat epilepsy, seizures, or convulsions),
  • herbal preparations containing St. John's wort (also known as Hypericum perforatum),
  • quinidine (used to treat heart rhythm disorders),
  • muscle relaxants,
  • medicines used to treat Parkinson's disease.

No interaction between Oxyduo and paracetamol, acetylsalicylic acid, or naltrexone is expected.
Oxyduo with food, drink, and alcohol
Drinking alcohol while taking Oxyduo may cause drowsiness or increase the risk of severe adverse effects such as shallow breathing with risk of apnoea and loss of consciousness. Drinking alcohol while taking Oxyduo is contraindicated.
Avoid drinking grapefruit juice while taking Oxyduo.
Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or plans to have a child, she should consult a doctor or pharmacist before using this medicine.
Pregnancy
Avoid using Oxyduo in pregnant women if possible, unless the doctor considers treatment with this medicine necessary. Long-term use of Oxyduo during pregnancy may cause withdrawal symptoms in the newborn. If oxycodone hydrochloride is used during childbirth, respiratory depression (slow and shallow breathing) may occur in the newborn.
Breastfeeding
Breastfeeding must be discontinued during treatment with Oxyduo. Oxycodone hydrochloride passes into breast milk. It is unknown whether naloxone hydrochloride also passes into breast milk. Therefore, the risk to the breastfed infant cannot be excluded, especially with repeated use of Oxyduo.
Driving and operating machinery
Oxyduo may impair the ability to drive and operate machinery as it may cause drowsiness and dizziness. This is particularly expected at the beginning of treatment with Oxyduo, after each dose increase, or after switching to another medicine. However, once the patient has been on a stable dose of Oxyduo for a prolonged period, these disturbances may subside.
This medicine has been associated with drowsiness and episodes of sudden sleep. If the patient experiences these adverse effects, they should not drive or operate machinery.
Discuss with the doctor if such adverse symptoms occur.
The patient should ask the doctor whether they can drive or operate machinery.
Oxyduo contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per tablet, i.e. it is essentially sodium-free.

3. How to take Oxyduo

This medicine should always be taken exactly as prescribed by your doctor. If in doubt, consult your doctor or pharmacist.
Before starting treatment and regularly during treatment, your doctor will discuss with you what to expect from taking Oxyduo, when and for how long you should take it, when to contact your doctor, and when you should stop taking it (see also "Stopping Oxyduo").
Oxyduo comes in the form of prolonged-release tablets, which means that the active substances are released over an extended period. Their effect lasts for 12 hours.

Oxyduo, 5 mg + 2.5 mg
Prolonged-release tablets must be swallowed whole. Do not divide, break, chew, or crush them.
Ingesting a divided, broken, chewed, or crushed tablet may result in the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking more Oxyduo than prescribed").

Oxyduo, 10 mg + 5 mg, 20 mg + 10 mg, 40 mg + 20 mg
Prolonged-release tablets may be divided into equal doses, but must not be chewed or crushed. Ingesting chewed or crushed tablets may lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking more Oxyduo than prescribed").

Unless otherwise prescribed by your doctor, the usual dose of Oxyduo is as follows:

Pain treatment
Adults
The usual starting dose is one prolonged-release tablet of Oxyduo containing 10 mg oxycodone hydrochloride + 5 mg naloxone hydrochloride every 12 hours.
Your doctor will decide the daily dose of Oxyduo you should take and how to divide the total daily dose into morning and evening doses. Your doctor will also determine any necessary dose adjustments during treatment. The dose will be adjusted according to the intensity of pain and your individual sensitivity. You should receive the lowest effective dose needed to control your pain. If you have previously been treated with opioid painkillers, treatment with Oxyduo may be started at higher doses.

The maximum daily dose is 160 mg oxycodone hydrochloride and 80 mg naloxone hydrochloride. If you require a higher dose, your doctor may prescribe additional doses of oxycodone hydrochloride without naloxone hydrochloride. However, the total daily dose of oxycodone hydrochloride should not exceed 400 mg. When additional doses of oxycodone hydrochloride are administered, the beneficial effect of naloxone hydrochloride on bowel function may be reduced.

If your doctor switches you from Oxyduo to another opioid painkiller, bowel function may worsen.

If you experience pain before the next scheduled dose of Oxyduo, you may need to take a fast-acting painkiller as needed. Oxyduo is not intended for this purpose. In such cases, consult your doctor.

If you feel the effect of Oxyduo is too strong or too weak, consult your doctor or pharmacist.

Restless legs syndrome treatment
Adults
The starting dose is 5 mg oxycodone hydrochloride + 2.5 mg naloxone hydrochloride every 12 hours.
Your doctor will decide the daily dose of Oxyduo you should take and how to divide the total daily dose into morning and evening doses. Your doctor will also determine any necessary dose adjustments during treatment. The dose will be adjusted according to your individual sensitivity. You should receive the lowest effective dose needed to relieve symptoms of restless legs syndrome.

If you feel the effect of the tablets is too strong or too weak, consult your doctor or pharmacist.

The maximum daily dose is 60 mg oxycodone hydrochloride and 30 mg naloxone hydrochloride.
If achieving the required dose with a specific strength is difficult or impractical, another strength of the same medicinal product may be prescribed.

Pain or restless legs syndrome treatment
Elderly patients
Dose adjustment is usually not necessary in elderly patients with normal liver and/or kidney function.

Impaired liver or kidney function
If you have impaired kidney function or mild liver impairment, your doctor may prescribe Oxyduo with special caution. Oxyduo must not be used if you have moderate to severe liver impairment (see also section 2 "When not to take Oxyduo" and "Warnings and precautions").

Children and adolescents under 18 years of age
Oxyduo has not been studied in children and adolescents under 18 years of age. Safety and efficacy have not been established in this population. Therefore, Oxyduo is not recommended for use in children and adolescents under 18 years of age.

Method of administration
Oxyduo, 5 mg + 2.5 mg
Tablets for oral use. Oxyduo should be swallowed with an adequate amount of liquid (half a glass of water). The tablet must be swallowed whole; do not divide, break, chew, or crush it. The tablet may be taken with or without food.

Oxyduo, 10 mg + 5 mg, 20 mg + 10 mg, 40 mg + 20 mg
Tablets for oral use. Oxyduo should be swallowed with an adequate amount of liquid (half a glass of water). The tablet may be divided into equal doses but must not be chewed or crushed. The tablet may be taken with or without food.

Oxyduo should be taken every 12 hours according to the prescribed treatment schedule (e.g., 8:00 a.m. and 8:00 p.m.).

Duration of treatment
Oxyduo should not be taken longer than necessary. If you are on long-term treatment with Oxyduo, your doctor should regularly assess whether you still need this medicine.

Taking more Oxyduo than prescribed
If you have taken more Oxyduo than prescribed, contact your doctor immediately.
Overdose symptoms may include:

  • Constricted pupils
  • Slow and shallow breathing (respiratory depression)
  • Drowsiness up to loss of consciousness
  • Reduced muscle tone (hypotonia)
  • Slowed heart rate
  • Low blood pressure
  • Brain dysfunction (known as toxic leukoencephalopathy). In severe cases, loss of consciousness (coma), pulmonary edema, and circulatory collapse may occur, which can lead to death in some cases.

Avoid activities requiring increased attention, such as driving.

Missed dose of Oxyduo
If you miss a dose of Oxyduo or take a lower dose than prescribed, you may not experience the medicine's effect.
If you forget to take a dose, follow these instructions:

  • If 8 hours or more remain until the next scheduled dose: take the missed dose immediately and continue taking the medicine according to the prescribed schedule.
  • If less than 8 hours remain until the next scheduled dose: take the missed dose, then wait 8 hours before taking the next dose. Try to return to your original dosing schedule (e.g., 8:00 a.m. and 8:00 p.m.).

Do not take more than one dose within 8 hours.
Do not take a double dose to make up for a missed dose.

Stopping Oxyduo
Do not stop taking Oxyduo without consulting your doctor. If treatment is no longer needed, the daily dose should be gradually reduced under medical supervision. This helps prevent withdrawal symptoms such as restlessness, sweating, and muscle pain.

If you have any further questions about the use of this medicine, consult your doctor or pharmacist.
