1. What is Oxyduo and what is it used for

Oxyduo is a prolonged-release tablet, which means that the active substances are released over a prolonged period. Their effect lasts for 12 hours.
These tablets can only be used in adults.

Pain relief

Oxyduo is indicated for the treatment of severe pain that can only be adequately controlled with opioid analgesics. Naloxone hydrochloride counteracts constipation.
How Oxyduo works to relieve pain
Oxyduo contains two active substances: oxycodone hydrochloride and naloxone hydrochloride.
Oxycodone hydrochloride is responsible for the analgesic effect of Oxyduo and is a strong opioid analgesic.
The second active substance of Oxyduo, naloxone hydrochloride, prevents constipation.
Gastrointestinal disorders (e.g., constipation) are a typical side effect of opioid analgesic treatment.

2. Important information before taking Oxyduo

When not to take 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, making it impossible to deliver sufficient oxygen to the blood and remove carbon dioxide produced in the body (respiratory depression),
• if the patient has severe lung disease associated with bronchial constriction (chronic obstructive pulmonary disease, COPD),
• if the patient has been diagnosed with a condition called cor pulmonale. In this case, the right side of the heart is enlarged due to increased pressure in the blood vessels in the lungs (e.g., as a result of COPD - see above), if the patient has been diagnosed with severe 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 disorders.

Warnings and precautions

Before starting treatment with Oxyduo, consult your doctor or pharmacist:

• in the case of elderly and frail patients,
• if the patient has paralytic ileus (a type of intestinal obstruction) caused by opioids,
• if the patient has kidney function disorders,
• if the patient has mild liver function disorders,
• if the patient has severe lung function disorders (i.e., reduced vital capacity),
• if the patient has a condition characterized by frequent breathing pauses during the night, which can cause daytime sleepiness (sleep apnea),
• if the patient has myxedema (a thyroid disorder characterized by dryness, decreased temperature, and swelling of the skin ["moon face"], including the face and limbs),
• if the thyroid gland does not produce enough hormones (underactive thyroid or hypothyroidism),
• if the adrenal glands do not produce enough hormones (adrenal insufficiency or Addison's disease),
• if the patient has a mental disorder with accompanying (partial) loss of reality (psychosis) caused by alcohol or other substance intoxication (substances that cause psychosis),
• if the patient has complaints related to gallstones or any other biliary disorders (biliary tract disease, gallbladder, etc.)
• if the patient has been diagnosed with benign prostatic hyperplasia (enlarged prostate),
• 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 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 taking or has taken MAO inhibitors (used to treat depression or Parkinson's disease) within the last two weeks, e.g., drugs containing tranylcypromine, phenelzine, isocarboxazid, moclobemide, and linezolid,
• if the patient experiences sleepiness or episodes of sudden sleepiness.

Consult your doctor if you experience severe abdominal pain that may radiate to the back, nausea, vomiting, or fever, as these may be symptoms related to pancreatitis and biliary disorders.
Respiratory disorders during sleep
Oxyduo may cause respiratory disorders during 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 consult their doctor. The doctor may consider reducing the dose.
Consult your doctor if the above information applied to you in the past.
Also, consult your doctor if any of the above disorders develop during treatment with Oxyduo. The most serious consequence of overdosing on opioid analgesics is respiratory depression(slow and shallow breathing). This can lead to, among other things, a decrease in oxygen levels in the blood, leading to fainting.
Diarrhea
If the patient experiences severe diarrhea at the beginning of treatment, it may be caused by the effect of naloxone. This may indicate that bowel function is returning to normal. Such diarrhea may occur within the first 3-5 days of treatment. If diarrhea persists after 3-5 days or bothers the patient, they should consult their doctor.
Switching to Oxyduo
When switching to Oxyduo after previously taking another opioid analgesic for a long time, initial withdrawal symptoms may occur, such as restlessness, especially motor restlessness, increased sweating, and muscle pain. If the patient experiences such symptoms, special medical supervision may be necessary.
Tolerance, dependence, and addiction
This medicine contains oxycodone, which is an opioid. It can cause dependence and (or) addiction.
This medicine contains oxycodone, which is an opioid analgesic. Repeated use of opioid analgesics can lead to decreased efficacy of the medicine (the patient becomes accustomed to it, which is called tolerance). Repeated use of Oxyduo can lead to dependence and abuse, which can lead to life-threatening overdose. The risk of these side effects may increase with increasing dose and longer treatment duration.
Dependence or abuse can cause the patient to feel that they have lost control over the dose of the medicine they take or how often they take it. The patient may feel that they need to continue taking the medicine, even if it no longer helps to relieve pain.
The risk of dependence on Oxyduo or addiction varies from person to person. The risk of Oxyduo dependence may be higher if:

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

If the patient notices any of the following symptoms while taking Oxyduo, it may indicate that they are developing tolerance to the medicine or are becoming dependent:

• the patient needs to take the medicine for a longer period than prescribed by the doctor;
• the patient needs to take a higher dose than prescribed;
• the patient uses the medicine for reasons other than those prescribed by the doctor, e.g., "to feel calm" or "to help sleep";
• the patient has repeatedly tried to stop or control the use of the medicine but has failed;
• the patient feels unwell after stopping the medicine and feels better after taking it again ("withdrawal symptoms").

If the patient notices any of these symptoms, they should consult their doctor to discuss the best treatment path, including when to stop taking the medicine and how to safely stop treatment (see section 3 "Stopping Oxyduo treatment").
Advanced cancer of the digestive tract or pelvis
The patient should inform their doctor if they have advanced cancer of the digestive tract or pelvis, where intestinal obstruction may be a problem.
Surgery
If the patient is to undergo surgery, they should inform their doctor about taking Oxyduo.
Effect on hormone production
Like other opioids, oxycodone can affect the normal production of hormones in the body, such as cortisol or sex hormones, especially if the patient has taken high doses for a long time. If the patient experiences symptoms that persist, such as nausea or vomiting, loss of appetite, fatigue, weakness, dizziness, changes in menstrual cycle, impotence, infertility, or decreased sex drive, they should talk to their doctor, who may order hormone level monitoring.
Hypersensitivity
This medicine may increase sensitivity to pain, especially in high doses. The patient should inform their doctor if this happens. It may be necessary to reduce the dose or change the medicine.
Residuals in feces
The patient may notice a residue of the prolonged-release tablet in their feces. They should not be concerned, as the active substances (oxycodone hydrochloride and naloxone hydrochloride) have already been released in the stomach and intestines and absorbed by the body.

Incorrect use of Oxyduo

Oxyduo is not suitable for treating withdrawal symptoms.
Oxyduo 5 mg + 2.5 mg
Prolonged-release tablets should be swallowed whole, without dividing, breaking, chewing, or crushing. Taking a divided, broken, chewed, or crushed tablet can lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking a higher dose of Oxyduo than prescribed").
Oxyduo 10 mg + 5 mg, 20 mg + 10 mg
Prolonged-release tablets can be divided into equal doses, but they should not be chewed or crushed. Taking chewed or crushed tablets can lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking a higher dose of Oxyduo than prescribed").
Abuse
Never abuse Oxyduo, especially if you are dependent on drugs. In people dependent on substances such as heroin, morphine, or methadone, abusing Oxyduo can cause severe withdrawal symptoms, as Oxyduo contains naloxone. Previous withdrawal symptoms may worsen.
Incorrect use
Oxyduo prolonged-release tablets should not be misused by dissolving and injecting the tablet contents (e.g., into blood vessels). The tablets contain, in particular, talc, which can cause local tissue breakdown (necrosis) and changes in lung tissue (pulmonary granulomas). Such abuse can also lead to other serious consequences, even death.
Doping
Taking Oxyduo may result in a positive test for stimulants (doping). Using Oxyduo as a stimulant can pose a health risk.

Oxyduo and other medicines

Tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
The risk of side effects increases if you take antidepressant medicines (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medicines can interact with oxycodone, which may cause the patient to experience symptoms such as involuntary, rhythmic muscle contractions, including muscles that control eye movements, agitation, excessive sweating, tremors, increased reflexes, increased muscle tone, and elevated body temperature above 38°C. If these symptoms occur, consult your doctor.
Concomitant use of opioids, including oxycodone hydrochloride, and sedative medicines such as benzodiazepines or other similar medicines increases the risk of sedation, breathing difficulties (respiratory depression), coma, and can be life-threatening. Therefore, concomitant use should only be considered when other treatment options are not possible.
If your doctor prescribes Oxyduo with sedative medicines, they should limit the dose and duration of concomitant treatment.
Tell your doctor about all sedative medicines you are taking and strictly follow your doctor's dosage instructions. It may be helpful to inform friends or relatives to be aware of the above symptoms. If such symptoms occur, consult your doctor. Examples of these sedative medicines or similar medicines include:

• other strong painkillers (opioid analgesics),
• medicines used to treat epilepsy, pain, and anxiety, such as gabapentin and pregabalin,
• sleeping pills and sedatives (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, which include phenothiazines and neuroleptics).

If you take these tablets at the same time as other medicines, the effect of these tablets or the other medicine, as described below, may change. Tell your doctor if you are taking:

• medicines that reduce blood clotting (coumarin derivatives), as the blood clotting time may be prolonged or shortened,
• 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 certain types of pain),
• 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 is expected between Oxyduo and paracetamol, acetylsalicylic acid, or naltrexone.

Oxyduo with food, drink, and alcohol

Drinking alcohol while taking Oxyduo can cause sedation or increase the risk of serious side effects, such as shallow breathing with the risk of apnea and loss of consciousness. Drinking alcohol while taking Oxyduo is contraindicated.
Avoid drinking grapefruit juice while taking Oxyduo.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine.
Pregnancy
Oxyduo should be avoided in pregnant women unless the doctor considers it necessary. Long-term use of Oxyduo during pregnancy may cause withdrawal symptoms in the newborn. If oxycodone hydrochloride is used during delivery, the newborn may experience respiratory depression (slow and shallow breathing).
Breastfeeding
Stop breastfeeding while taking Oxyduo. Oxycodone hydrochloride passes into breast milk. It is not known 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 using machines

Oxyduo may impair the ability to drive and use machines because it can cause sedation and dizziness. This effect is particularly expected at the beginning of treatment with Oxyduo, after each dose increase, or when switching to another medicine. However, when the patient has been taking a fixed dose of Oxyduo for a long time, these disorders may disappear.
Oxyduo has been associated with sedation and sudden sleep episodes. If the patient experiences these side effects, they should not drive or operate machinery.
Talk to your doctor if you experience these side effects.
The patient should ask their doctor if they can drive or operate machinery.

Oxyduo contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per tablet, which is essentially sodium-free.

3. How to take Oxyduo

Always take this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
Before starting treatment and regularly during treatment, your doctor will discuss with you what to expect from Oxyduo, when and how long to take it, when to contact your doctor, and when to stop taking it (see also "Stopping Oxyduo treatment").
Oxyduo is a prolonged-release tablet, which means that the active substances are released over a prolonged period. Their effect lasts for 12 hours.
Oxyduo, 5 mg + 2.5 mg

Prolonged-release tablets should be swallowed whole, without dividing, breaking, chewing, or crushing. Taking a divided, broken, chewed, or crushed tablet can lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking a higher dose of Oxyduo than prescribed").

Oxyduo, 10 mg + 5 mg, 20 mg + 10 mg

Prolonged-release tablets can be divided into equal doses, but they should not be chewed or crushed. Taking chewed or crushed tablets can lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see section 3 "Taking a higher dose of Oxyduo than prescribed").

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

Pain relief
Adults
Typically, the initial dose is 1 prolonged-release tablet of Oxyduo 10 mg oxycodone hydrochloride + 5 mg naloxone hydrochloride every 12 hours.
Your doctor will decide what dose of Oxyduo you should take daily and how to divide the daily dose into morning and evening doses. Your doctor will also decide on any necessary dose adjustments during treatment. Your doctor will adjust the dose according to the severity of your pain and your individual sensitivity. You should receive the smallest effective dose to control your pain. If you have previously taken opioid analgesics, treatment with Oxyduo can be started at a higher dose.
The maximum daily dose is 160 mg of oxycodone hydrochloride and 80 mg of naloxone hydrochloride. If you need a higher dose, your doctor may prescribe additional doses of oxycodone hydrochloride without naloxone hydrochloride. However, do not take more than the maximum daily dose of 400 mg of oxycodone hydrochloride. When taking additional doses of oxycodone hydrochloride, the beneficial effect of naloxone hydrochloride on bowel function may be impaired.
If your doctor prescribes a change from Oxyduo to another opioid analgesic, bowel function may worsen.
If you experience pain before the next dose of Oxyduo is due, you may need to take a fast-acting painkiller. Oxyduo is not intended for this purpose. In such cases, consult your doctor.
If you feel that the effect of Oxyduo is too strong or too weak, talk to your doctor or pharmacist.
Pain relief
Elderly patients
Usually, no dose adjustment is necessary in elderly patients with normal liver and/or kidney function.
Liver or kidney function disorders
If you have kidney or mild liver function disorders, your doctor may prescribe Oxyduo with caution. If you have moderate to severe liver function disorders, do not take Oxyduo (see also section 2 "When not to take Oxyduo" and "Warnings and precautions").

Children and adolescents under 18 years

Oxyduo has not been studied in children and adolescents under 18 years. The safety and efficacy of Oxyduo in children and adolescents have not been established. Therefore, Oxyduo should not be used in children and adolescents under 18 years.

Method of administration

Oxyduo, 5 mg + 2.5 mg
Oral tablets. Oxyduo should be swallowed with a sufficient amount of liquid (half a glass of water). The tablet should be swallowed whole, without dividing, breaking, chewing, or crushing. The tablet can be taken with or without food.
Oxyduo, 10 mg + 5 mg, 20 mg + 10 mg
Oral tablets. Oxyduo should be swallowed with a sufficient amount of liquid (half a glass of water). The tablet can be divided into equal doses, but it should not be chewed or crushed. The tablet can be taken with or without food.
Oxyduo should be taken every 12 hours, according to the established treatment schedule (e.g., in the morning at 8:00, in the evening at 20:00).

Duration of treatment

As a rule, do not take Oxyduo for longer than necessary. If you are being treated with Oxyduo for a long time, your doctor will regularly check if you still need Oxyduo.

Taking a higher dose of Oxyduo than prescribed

If you have taken a higher dose of Oxyduo than prescribed, contact your doctor immediately.
Overdose can cause:

• pupil constriction
• slow and shallow breathing (respiratory depression)
• sedation leading to loss of consciousness
• decreased muscle tone (hypotonia)
• slow heart rate
• low blood pressure
• brain disorders (toxic leukoencephalopathy). In severe cases, it can lead to loss of consciousness (coma), fluid accumulation in the lungs, and circulatory collapse, which can be fatal.

Avoid activities that require increased attention, such as driving.

Missing a dose of Oxyduo

If you miss a dose of Oxyduo or take a lower dose than prescribed, you may not feel the effect of the medicine.
If you forget to take a dose, follow the instructions below:

• If there are 8 hours or more until the next dose: take the missed dose immediately and continue taking the medicine according to the established schedule.
• If there are less than 8 hours until the next dose: take the missed dose. Then, wait 8 hours before taking the next dose. Try to return to the original dosing schedule (e.g., in the morning at 8:00, in the evening at 20:00).

Do not take more than one dose in 12 hours.
Do not take a double dose to make up for a missed dose.

Stopping Oxyduo treatment

Do not stop taking Oxyduo without consulting your doctor. If treatment is no longer necessary, gradually reduce the daily dose after consulting your doctor. This way, you can avoid withdrawal symptoms, such as restlessness, sweating, and muscle pain.
If you have any further doubts about taking this medicine, consult your doctor or pharmacist.
