1. What is Oxylaxon and what is it used for

Pain treatment

Oxylaxon has been prescribed to treat severe pain that can only be adequately controlled with opioid painkillers.

How Oxylaxon works on pain

Oxylaxon contains the active substances oxycodone hydrochloride and naloxone hydrochloride.
Oxycodone is responsible for the pain-relieving effect of the medicine. It is a strong painkiller that belongs to a group of medicines called opioids.
Naloxone counteracts constipation, which is a typical side effect of strong painkillers (opioids).

2. Important information before taking Oxylaxon

When not to take Oxylaxon

  • if the patient is allergic to oxycodone, naloxone, or any of the other ingredients of this medicine (listed in section 6);
  • if the patient has breathing problems, such as slower or shallower breathing than normal (respiratory depression);
  • if the patient has severe lung disease associated with narrowing of the airways (chronic obstructive pulmonary disease);
  • if the patient has a condition called cor pulmonale (right-sided heart failure due to increased blood pressure in the pulmonary vessels);
  • if the patient has severe asthma;
  • if the patient has a condition called paralytic ileus (a condition where the intestines do not work properly and there is a build-up of food, fluid, and gas in the intestines), not caused by opioids;
  • if the patient has moderate to severe liver failure.

Warnings and precautions

Before starting treatment with Oxylaxon, the patient should discuss it with their doctor or pharmacist.

  • in the case of elderly patients and weakened patients;
  • if the patient has opioid-induced constipation;
  • in the case of kidney problems;
  • in the case of mild liver failure;
  • if the patient has severe lung problems (e.g., reduced breathing ability);
  • if the patient has a condition characterized by frequent pauses in breathing during sleep, which can cause daytime sleepiness (sleep apnea);
  • if the patient has a condition called hypothyroidism (a condition where the thyroid gland does not produce enough hormones);
  • if the patient has adrenal gland problems (adrenal insufficiency), such as Addison's disease;
  • in the case of mental illness with loss of contact with reality (psychosis), caused by alcohol or other substances (substance-induced psychosis);
  • if the patient has gallstones;
  • in the case of an enlarged prostate gland;
  • in the case of pancreatitis;
  • in the case of low blood pressure;
  • in the case of high blood pressure;
  • in the case of heart problems;
  • in the case of head injuries (due to the risk of increased intracranial pressure);
  • if the patient has epilepsy or a tendency to seizures;
  • if the patient is taking MAO inhibitor medicines (used to treat depression or Parkinson's disease), such as tranylcypromine, phenelzine, isocarboxazid, and moclobemide;
  • if the patient experiences sleepiness or episodes of sudden sleepiness.

The patient should inform their doctor if they have had any of the above conditions in the past. The patient should also contact their doctor if they occur during treatment with Oxylaxon.
Respiratory depression during sleep
Oxylaxon may cause respiratory depression associated with sleep, such as sleep apnea (pauses in breathing during sleep) and hypoxemia during sleep (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to shortness of breath, difficulty staying asleep, or excessive daytime sleepiness. If the patient or another person notices such symptoms, they should contact their doctor. The doctor may consider reducing the dose.
Tolerance, dependence, and addiction
This medicine contains oxycodone, which is an opioid. It may cause dependence and (or) addiction.
This medicine contains oxycodone, which is an opioid medicine. Repeated use of opioid painkillers may lead to reduced effectiveness of the medicine (the patient's body gets used to it, which is called tolerance).
Long-term use of Oxylaxon may lead to dependence, abuse, and addiction, which can be life-threatening. The risk of these side effects may be higher when using higher doses for a longer period.

  • if the patient or a family member has ever abused or been dependent on alcohol, prescription medicines, or illegal drugs ("addiction");
  • if the patient is a smoker;
  • if the patient has had mood disorders (depression, anxiety, or personality disorder) or has been treated by a psychiatrist for other mental disorders.

If the patient notices any of the following symptoms while taking Oxylaxon, it may indicate that they are developing dependence or addiction.

  • need to take the medicine for a longer period than prescribed by the doctor;
  • need to take a higher dose than prescribed;
  • using the medicine for reasons other than prescribed, such as "to calm down" or "to help fall asleep";
  • making repeated, unsuccessful attempts to stop or reduce the use of the medicine;
  • feeling unwell after stopping the medicine and improving after taking it again ("withdrawal effect").

If the patient observes any of these symptoms, they should contact their doctor to discuss the best treatment plan, including the right time and safe way to stop treatment (see section 3 "Stopping Oxylaxon treatment").
Oxylaxon is not recommended for patients with advanced intestinal or pelvic cancer, where intestinal obstruction may occur.
If the patient experiences acute diarrhea at the start of treatment (within the first 3-5 days), it may be an effect of naloxone. This may be a sign that bowel function is returning to normal. If diarrhea persists after 3-5 days or bothers the patient, they should contact their doctor.
If the patient has previously taken high doses of other opioids, when switching to Oxylaxon, they may initially experience withdrawal symptoms (such as restlessness, sweating, and muscle pain). If such symptoms occur, the patient may require special medical supervision.
If the patient is to undergo surgery, they should inform their doctor that they are taking Oxylaxon.
The patient should consult their doctor if they experience severe abdominal pain that may radiate to the back, nausea, vomiting, or fever, as these may be symptoms related to pancreatitis and bile duct problems.
During long-term use of Oxylaxon, the patient may develop tolerance to the medicine. This means that the patient may require higher doses to achieve the desired effect. Long-term use of this medicine may lead to physical dependence. The patient should avoid taking medicines containing oxycodone if they have a history of alcohol, drug, or medicine abuse. If treatment is stopped suddenly, withdrawal symptoms may occur. If the patient no longer needs treatment, the daily dose should be gradually reduced, in agreement with the doctor.
Remnants of prolonged-release tablets may be found in the stool. The patient should not be concerned, as the active substance has been released in the stomach and intestines and absorbed by the body.
Improper use of Oxylaxon
Never misuse Oxylaxon, especially if the patient is addicted to medicines. In the case of addiction to drugs such as heroin, morphine, or methadone, misusing Oxylaxon may cause severe withdrawal symptoms, as it contains the active substance naloxone. Previous withdrawal symptoms may worsen.
It is not allowed to misuse Oxylaxon prolonged-release tablets by dissolving them and injecting them (e.g., into blood vessels) or by inhaling them. The tablets contain talc, which can cause local tissue damage (necrosis) and changes in lung tissue (pulmonary granulomas). Misuse of the medicine can have other serious consequences, even death.
Prolonged-release tablets should be swallowed whole, without affecting the slow release of oxycodone from the tablet. The tablets should not be divided, broken, chewed, or crushed. Taking divided, broken, chewed, or crushed tablets can release a potentially fatal dose of oxycodone into the body (see section 3 "Taking a higher dose of Oxylaxon than prescribed").
Taking Oxylaxon may result in positive doping test results.
Taking Oxylaxon as a stimulant can be life-threatening.

Children and adolescents

Oxylaxon should not be used in children and adolescents under 18 years of age, as its safety and efficacy have not been established.

Oxylaxon and other medicines

The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
The risk of side effects increases if Oxylaxon is taken with other medicines that affect brain function. In such cases, the patient may feel sleepy or have breathing problems (respiratory depression).
Medicines that affect brain function:

  • other strong painkillers (opioids),
  • sleeping pills and sedatives,
  • antidepressants (e.g., paroxetine, fluoxetine),
  • medicines used to treat allergies, motion sickness, or nausea (antihistamines or antiemetics),
  • other medicines that affect the nervous system (phenothiazines, neuroleptics).

The risk of side effects increases if the patient takes antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medicines can interact with oxycodone, causing symptoms such as involuntary, rhythmic muscle contractions, including muscles that control eye movements, agitation, excessive sweating, shivering, increased reflexes, increased muscle tension, and elevated body temperature above 38°C. If these symptoms occur, the patient should contact their doctor.
Concomitant use of Oxylaxon and sedatives, such as benzodiazepines or related medicines, increases the risk of sleepiness, breathing difficulties (respiratory depression), or sleepiness, which can be life-threatening. Therefore, combination therapy should only be considered when other treatment options are not available.
If Oxylaxon is taken with sedatives, the doctor should limit the dose and duration of concomitant use.
The patient should tell their doctor about all sedatives they are taking and strictly follow the prescribed dose. It may be helpful to inform a family member or close friend of the patient about the possibility of these symptoms. If these symptoms occur, the patient should consult their doctor.
The patient should inform their doctor about the following medicines:

  • medicines that reduce blood clotting (coumarin derivatives), as bleeding time may be accelerated or slowed;
  • macrolide antibiotics (e.g., clarithromycin, erythromycin, telithromycin),
  • azole antifungal medicines (e.g., ketoconazole, voriconazole, itraconazole, posaconazole),
  • ritonavir or other protease inhibitors (used to treat HIV, such as indinavir, nelfinavir, saquinavir),
  • cimetidine (a medicine used to treat stomach ulcers, indigestion, or heartburn),
  • rifampicin (used to treat tuberculosis),
  • carbamazepine (used to treat seizures, fits, or certain types of pain),
  • phenytoin (used to treat seizures, fits, or convulsions),
  • St. John's Wort,
  • quinidine (a medicine used to treat irregular heart rhythm),
  • medicines used to treat depression,
  • medicines used to treat allergies, motion sickness, or nausea (antihistamines or antiemetics),
  • medicines used to treat mental disorders (antipsychotics or neuroleptics),
  • muscle relaxants,
  • medicines used to treat Parkinson's disease.

Taking Oxylaxon with food, drink, and alcohol

Consuming alcohol while taking Oxylaxon may cause sleepiness or increase the risk of serious side effects, such as shallow breathing with a risk of respiratory arrest and loss of consciousness. The patient should avoid drinking alcohol while taking Oxylaxon.
The patient should avoid drinking grapefruit juice while taking Oxylaxon.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant, breastfeeding, or thinks they may be pregnant, they should consult their doctor or pharmacist before taking this medicine.
Pregnancy
Whenever possible, Oxylaxon should be avoided during pregnancy. If the medicine is used during pregnancy for a long time, oxycodone may cause withdrawal symptoms in the newborn. If oxycodone is given during delivery, the newborn may experience respiratory depression (slow and shallow breathing).
Breastfeeding
The patient should stop breastfeeding while taking Oxylaxon. Oxycodone passes into breast milk. It is not known if naloxone also passes into breast milk. For this reason, there is a risk to the breastfed child, especially if the mother takes multiple doses of Oxylaxon.

Driving and using machines

This medicine may affect the patient's ability to drive and use machines, as it may cause sleepiness or dizziness. This is most likely to happen at the start of treatment, after a dose increase, or when switching to this medicine from another.
Oxylaxon may cause sleepiness or sudden sleep episodes. If these occur, the patient should not drive or operate machinery.
The patient should consult their doctor or pharmacist if they are unsure whether they can drive while taking this medicine.

Oxylaxon 5 mg+2.5 mg and 10 mg+5 mg contain lactose

Patients with intolerance to some sugars should consult their doctor before taking this medicine.
This medicine contains less than 1 mmol of sodium (23 mg) per prolonged-release tablet, which means it is "sodium-free".

3. How to take Oxylaxon

This medicine should always be taken exactly as prescribed by the doctor. If the patient has any doubts, they should consult their doctor or pharmacist.
If it is difficult to take the required dose using the prescribed strength of the medicine, the patient may take a different strength of the same medicinal product.
Before starting treatment and regularly during treatment, the doctor will discuss with the patient what to expect from taking Oxylaxon, when and for how long to take it, when to contact the doctor, and when to stop taking it (see also "Stopping Oxylaxon treatment").

If the doctor has not prescribed otherwise, the usual dose of Oxylaxon is:

For pain treatment

Adults
The usual starting dose is 10 mg of oxycodone hydrochloride and 5 mg of naloxone hydrochloride every 12 hours.
The doctor will decide what total daily dose should be taken and how it should be divided into morning and evening doses. The doctor will also decide on any necessary dose adjustments during treatment, depending on the severity of the pain and the patient's individual sensitivity. The patient should take the lowest effective dose to relieve pain. If the patient has previously taken opioids, treatment with Oxylaxon may be started at a higher initial dose.
The maximum daily dose is 160 mg of oxycodone hydrochloride and 80 mg of naloxone hydrochloride. If higher doses are necessary, the doctor may prescribe an additional dose of oxycodone without naloxone. However, the maximum daily dose of oxycodone hydrochloride should not exceed 400 mg. When additional doses of oxycodone hydrochloride are given, the beneficial effect of naloxone hydrochloride on bowel function may be reduced.
If the patient experiences pain between doses, they may need to take a different, fast-acting painkiller. Oxylaxon is not intended for this purpose. The patient should consult their doctor in such cases.
If the patient feels that the effect of the medicine is too strong or too weak, they should consult their doctor or pharmacist.

Special warnings for some patient groups

Elderly patients
Usually, there is no need to adjust the dose in elderly patients with normal kidney and liver function.
Patients with kidney or liver problems
If the patient has kidney or mild liver problems, the doctor will prescribe Oxylaxon with caution. The patient should not take Oxylaxon if they have moderate to severe liver failure (see also section 2 "When not to take Oxylaxon" and "Warnings and precautions").
Children and adolescents under 18 years of age
Oxylaxon has not been studied in children and adolescents. Therefore, this medicine is not recommended for patients under 18 years of age.

Method of administration

Oral use.

In severe cases, overdose may cause loss of consciousness (coma), fluid accumulation in the lungs, and circulatory failure, which can be life-threatening.
The patient should avoid situations that require increased attention (e.g., driving vehicles).

Missing a dose of Oxylaxon

If the patient misses a dose of Oxylaxon or takes a lower dose than prescribed, they may not feel the effects of the medicine.
If the patient forgets to take a dose, they should follow these instructions:

  • if the next dose is to be taken in 8 hours or more: the patient should take the missed dose immediately and continue treatment according to the normal schedule;
  • if the next dose is to be taken in less than 8 hours: the patient should take the missed dose and then wait 8 hours before taking the next dose. The patient should try to return to their normal dosing schedule (e.g., 8 am and 8 pm).

The patient should not take more than one dose in 8 hours.
The patient should not take a double dose to make up for a missed dose.

Stopping Oxylaxon treatment

The patient should not stop taking Oxylaxon without consulting their doctor.
If the patient no longer needs treatment, the doctor will recommend gradually reducing the daily dose. This way, the patient can avoid withdrawal symptoms, such as restlessness, sweating, and muscle pain.
If the patient has any further doubts about taking this medicine, they should consult their doctor or pharmacist.
