1. What Oxicodona/Naloxona Viatris is and what it is used for

You have been prescribed Oxicodona/Naloxona Viatris for the treatment of intense pain that can only be adequately treated with opioid analgesics.

How Oxicodona/Naloxona Viatris relieves pain

Oxicodona/Naloxona Viatris contains oxycodone hydrochloride and naloxone hydrochloride as active ingredients. Oxycodone hydrochloride is responsible for the analgesic effect of Oxicodona/Naloxona Viatris, and it is a potent analgesic belonging to the group of medications called opioids.

The second active ingredient of Oxicodona/Naloxona Viatris, naloxone hydrochloride, has the function of counteracting constipation. Intestinal dysfunction (e.g., constipation) is a typical side effect of treatment with opioid analgesics.

Oxicodona/Naloxona Viatris is a prolonged-release tablet, which means that its active ingredients are released over a prolonged period. Its action lasts 12 hours.

2. What you need to know before taking Oxicodona/Naloxona Viatris

Do not take Oxicodona/Naloxona Viatris

• if you are allergic to oxycodone hydrochloride, naloxone hydrochloride, or any of the other components of this medication (listed in section 6),
• if your breathing does not provide enough oxygen to the blood or remove the carbon dioxide produced in the body (respiratory depression),
• if you have a severe lung disease associated with narrowing of the airways (chronic obstructive pulmonary disease or COPD),
• if you have a disorder known as cor pulmonale. This disorder consists of the right side of the heart increasing in size due to increased pressure in the blood vessels of the lungs, etc. (e.g., as a result of COPD, see above),
• if you have severe bronchial asthma,
• if you have paralytic ileus (a type of intestinal obstruction) not caused by opioids,
• if you have moderate to severe liver problems.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Oxicodona/Naloxona Viatris:

• if you are an elderly or debilitated patient (weak),
• if you have paralytic ileus (a type of intestinal obstruction) caused by opioids,
• if you have kidney problems,
• if you have mild liver problems,
• if you have severe lung problems (i.e., reduced ability to breathe),
• if you have a disorder characterized by frequent interruptions in breathing that make you feel sleepy during the day (sleep apnea),
• if you have myxedema (a thyroid disorder characterized by dryness, coldness, and swelling of the skin, affecting the face and limbs),
• if your thyroid gland does not produce enough hormones (underactive thyroid or hypothyroidism),
• if your adrenal gland functions poorly, e.g., in Addison's disease,
• if you have a mental illness accompanied by a loss (partial) of reality (psychosis), due to alcoholism or intoxication with other substances (substance-induced psychosis),
• if you have problems with gallstones,
• if you have an abnormal increase in the size of the prostate (prostate hypertrophy),
• if you have alcoholism or delirium tremens,
• if you have pancreatitis (inflammation of the pancreas),
• if you have low blood pressure (hypotension),
• if you have high blood pressure (hypertension),
• if you have any previous cardiovascular disease,
• if you have a head injury (due to the risk of increased pressure in the brain),
• if you have epilepsy or are prone to seizures,
• if you are also receiving treatment with MAO inhibitors (used to treat depression or Parkinson's disease), e.g., medications containing tranylcypromine, phenelzine, isocarboxazid, moclobemide, and linezolid,
• if you feel drowsy or fall asleep sometimes.

Contact your doctor if you experience severe abdominal pain that may radiate to the back, nausea, vomiting, or fever, as these may be symptoms associated with pancreatitis or biliary tract disease.

Tolerance, dependence, and addiction

This medication contains oxycodone, which is an opioid medication. Repeated use of opioid analgesics can make the medication less effective (you get used to it, which is known as tolerance).

Repeated use of Oxicodona/Naloxona Viatris can cause dependence, abuse, and addiction, which can lead to a life-threatening overdose. The risk of these side effects may increase with higher doses and longer treatment duration.

Dependence or addiction can make you feel like you no longer have control over the amount of medication you need to take or how often you need to take it. You may feel like you need to continue taking the medication, even when it no longer helps relieve your pain.

The risk of becoming dependent or addicted varies from person to person. You may have a higher risk of becoming dependent or addicted to Oxicodona/Naloxona Viatris:

• if you or a family member has a history of substance abuse or dependence (addiction),
• if you smoke,
• if you have ever had problems with your mood (depression, anxiety, or personality disorder) or have received psychiatric treatment for other mental illnesses.

If you notice any of the following signs while taking Oxicodona/Naloxona Viatris, it could be a sign that you have become dependent or addicted.

• You need to take the medication for a longer period than recommended by your doctor.
• You need to take more doses than recommended.
• You are using the medication for reasons other than those prescribed, e.g., "to calm down" or "to help you sleep".
• You have made repeated attempts to stop or control the use of the medication without success.
• You do not feel well when you stop taking the medication and feel better once you take it again ("withdrawal symptoms").

If you notice any of these signs, talk to your doctor to discuss the best treatment for you, including when it is appropriate to stop taking it and how to do so safely (see section 3, If you stop treatment with Oxicodona/Naloxona Viatris).

Consult your doctor if you have had any of these diseases in the past. Also, inform your doctor if you experience any of them during treatment with this medication.

The most serious consequence of opioid overdose is respiratory depression(slow and shallow breathing). This can also cause oxygen levels in the blood to decrease, leading to fainting, etc.

There is no clinical experience with this medication in patients with cancer associated with peritoneal metastases or in patients with advanced digestive and pelvic cancers with initial intestinal obstruction.

Therefore, the use of this medication is not recommended in these patients.

Children and adolescents

This medication should not be administered to children and adolescents under 18 years of age, as its benefits and safety have not been established.

How to take Oxicodona/Naloxona Viatris correctly

Diarrhea

If you experience severe diarrhea at the start of treatment, it may be due to the effect of naloxone. It can be a sign that intestinal function is normalizing. This diarrhea may occur in the first 3 to 5 days of treatment. If it persists after this period or if you are concerned, contact your doctor.

Switching to Oxicodona/Naloxona Viatris

If you have been receiving high doses of another opioid, you may experience withdrawal symptoms shortly after starting treatment with this medication, e.g., restlessness, sweating, and muscle pain. If you experience any of these symptoms, you may need special monitoring by your doctor. This medication is not suitable for treating withdrawal.

Surgery

If you need to undergo surgery, inform your doctors that you are being treated with oxycodone/naloxone.

Long-term treatment

If you use this medication for a long time, you may experience tolerance. This means you will need a higher dose to achieve the desired pain relief. Long-term use of this medication can also lead to physical dependence. Withdrawal symptoms may occur if treatment is stopped abruptly (restlessness, sweating, muscle pain). If you no longer need treatment, you should gradually reduce the daily dose, consulting your doctor.

Psychological dependence

The active ingredient oxycodone hydrochloride has the same potential for abuse as other potent opioids (potent analgesics). It can create psychological dependence. Medications containing oxycodone hydrochloride should be avoided in patients with a history of alcohol, drug, or medication abuse.

Misuse

Never dissolve the prolonged-release tablets of Oxicodona/Naloxona Viatris to inject them (e.g., into a blood vessel). The reason is that they contain talc, which can cause local tissue destruction (necrosis) and lung tissue alterations (pulmonary granuloma). This abuse can also have other serious consequences and even cause death.

Incorrect use of Oxicodona/Naloxona Viatris

Please note that although the tablets can be divided, they should not be broken, chewed, or crushed.

Taking chewed or crushed tablets can affect the slow-release properties of the tablet and lead to the absorption of a potentially fatal dose of oxycodone hydrochloride (see "If you take more Oxicodona/Naloxona Viatris than you should").

Abuse

Never abuse Oxicodona/Naloxona Viatris, especially if you have a history of substance abuse. If you are addicted to substances like heroin, morphine, or methadone, you may experience severe withdrawal symptoms if you misuse this medication, as it contains the active ingredient naloxone. It can worsen pre-existing withdrawal symptoms.

Doping

Athletes should be aware that this medication can cause a positive reaction in anti-doping tests. The use of oxycodone/naloxone as a doping agent can endanger health.

Other medications and Oxicodona/Naloxona Viatris

Inform your doctor if you are taking, have recently taken, or may need to take any other medication.

The risk of experiencing side effects increases if you take this medication at the same time as medications that affect brain function. In this case, the side effects of this medication can be enhanced, and your life may be at risk. For example, you may experience drowsiness or somnolence, or respiratory depression (slow and shallow breathing) or coma may worsen. Due to this, concomitant use should only be considered when other treatment options are not possible.

Examples of medications that affect brain function:

• other potent analgesics (opioids),
• medications for treating epilepsy, pain, and anxiety, such as gabapentin and pregabalin,
• sleeping pills and tranquilizers (sedatives like benzodiazepines, hypnotics, anxiolytics),
• antidepressants,
• medications used to treat allergies, dizziness, or nausea (antihistamines or antiemetics),
• other medications for treating psychiatric or mental disorders (antipsychotics, including phenothiazines or neuroleptics),
• muscle relaxants,
• medications for treating Parkinson's disease.

However, if your doctor prescribes oxycodone/naloxone along with sedative medications, your doctor should limit the dose and duration of concomitant treatment.

The risk of side effects increases if you use antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medications can interact with oxycodone and may cause symptoms such as involuntary muscle contractions, agitation, excessive sweating, tremors, exaggerated reflexes, increased muscle tension, and body temperature above 38 °C. Contact your doctor if you experience these symptoms.

Inform your doctor about all sedative medications you are taking and follow your doctor's recommendations closely. It may be helpful to inform friends or family members who are aware of the signs and symptoms mentioned above. Contact your doctor when you experience these symptoms.

Inform your doctor if you are taking any of the following medications:

• medications that reduce blood clotting (coumarin derivatives), as the coagulation rate may increase or decrease,
• macrolide antibiotics (such as clarithromycin),
• antifungal agents of the azole type (e.g., ketoconazole),
• ritonavir or other protease inhibitors (used to treat HIV),
• cimetidine (a medication for treating stomach ulcers, indigestion, or acidity),
• rifampicin (used to treat tuberculosis),
• carbamazepine (used to treat seizures or certain painful conditions),
• phenytoin (used to treat seizures),
• a herbal remedy called St. John's Wort (also known as Hypericum perforatum),
• quinidine (a medication for treating arrhythmias).

No interactions are expected between oxycodone/naloxone and paracetamol, acetylsalicylic acid, or naltrexone.

Taking Oxicodona/Naloxona Viatris with food, drinks, and alcohol

Drinking alcohol while taking this medication can make you feel more drowsy or increase the risk of serious side effects, such as shallow breathing with the risk of stopping breathing, and loss of consciousness. It is recommended not to drink alcohol while taking this medication.

You should avoid drinking grapefruit juice while taking this medication.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Pregnancy

This medication should be avoided during pregnancy whenever possible. If used during prolonged periods of pregnancy, oxycodone hydrochloride may cause withdrawal symptoms in the newborn. If oxycodone hydrochloride is administered during labor, the newborn may experience respiratory depression (slow and shallow breathing).

Breastfeeding

Breastfeeding should be discontinued during treatment with this medication. Oxycodone hydrochloride passes into breast milk. It is not known if naloxone hydrochloride also passes into breast milk. Therefore, the risk to the infant cannot be ruled out, especially if the mother receives multiple doses of this medication.

Driving and using machines

This medication can affect your ability to drive or operate machines. In particular, this is more likely at the start of treatment with this medication, after a dose increase, or after switching to a different medication. However, these side effects disappear once you have a stable dose of oxycodone/naloxone.

Medications containing oxycodone/naloxone, such as Oxicodona/Naloxona Viatris, have been associated with drowsiness and sudden sleep episodes. If you experience this side effect, you should not drive or operate machinery. Inform your doctor if you experience these side effects.

Consult your doctor if you can drive or operate machinery.

Oxicodona/Naloxona Viatris contains sodium

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

3. How to Take Oxicodona/Naloxona Viatris

Follow your doctor's instructions for taking this medication exactly. If you are unsure, consult your doctor or pharmacist again.

Before starting treatment and periodically during treatment, your doctor will discuss with you what you can expect from using Oxicodona/Naloxona Viatris, when and for how long you should take it, when to contact your doctor, and when you should stop taking it (see also "If you stop taking Oxicodona/Naloxona Viatris").

Unless your doctor tells you otherwise, the usual dose is:

To treat pain

Adults

The usual initial dose is 10 mg of oxycodone hydrochloride/5 mg of naloxone hydrochloride in prolonged-release tablets every 12 hours.

Your doctor will decide the dose of oxycodone/naloxone you should take per day and how to divide it into morning and evening doses. They will also decide if the dose needs to be adjusted during treatment. Your dose will be adjusted according to your degree of pain and individual sensitivity. You should receive the minimum dose necessary to relieve pain. If you have already received treatment with opioids, the initial dose of this medication may be higher.

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 give you additional oxycodone hydrochloride without naloxone hydrochloride. However, the maximum daily dose of oxycodone hydrochloride should not exceed 400 mg.

The beneficial effect of naloxone hydrochloride on intestinal activity may be affected if the dose of oxycodone hydrochloride is increased without increasing the dose of naloxone hydrochloride.

If you replace this medication with another opioid analgesic, your intestinal function may worsen.

If you experience pain between two doses of this medication, you may need to take an additional fast-acting analgesic. This medication is not suitable for this purpose. Discuss this with your doctor.

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

Elderly patients

In general, it is not necessary to adjust the dose in elderly patients with normal kidney and/or liver function.

Liver or kidney problems

If you have liver or kidney disorders of any degree or mild liver disorders, your doctor will prescribe this medication with special caution. If you have moderate or severe liver disorders, you should not take Oxicodona/Naloxona Viatris (see also section 2 "Do not take Oxicodona/Naloxona Viatris" and "Warnings and precautions").

Children and adolescents under 18 years

Oxycodone/naloxone has not been studied in children and adolescents under 18 years. Its safety and efficacy in children and adolescents have not been established. For this reason, the use of this medication is not recommended in children and adolescents under 18 years.

Method of administration

Oral.

Take this medication every 12 hours, following a fixed schedule (e.g., 8 am and 8 pm).

This medication should be taken with sufficient liquid (half a glass of water). The tablet can be divided into equal doses. However, it should not be broken, chewed, or crushed. The tablet can be taken with or without food.

Duration of use

In general, you should not take this medication for longer than necessary. If you receive this medication for a long time, your doctor should regularly check that you still need it.

If you take more Oxicodona/Naloxona Viatris than you should

If you have taken more oxycodone/naloxone than prescribed, inform your doctor immediately.

Consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount used. It is recommended to take the package and the medication package leaflet to the healthcare professional.

An overdose can cause:

• constricted pupils
• slow and shallow breathing (respiratory depression)
• a state similar to narcosis (somnolence that can lead to loss of consciousness)
• low muscle tone (hypotonia)
• reduced heart rate
• decreased blood pressure
• a brain disorder (known as toxic leukoencephalopathy)

In severe cases, loss of consciousness (coma), fluid accumulation in the lungs, and circulatory collapse can occur, which can be fatal.

You should avoid situations that require a high level of alertness, such as driving.

If you forget to take Oxicodona/Naloxona Viatris

If you forget to take this medication or take a lower dose than prescribed, you may stop feeling the analgesic effect.

If you forget to take a dose, follow these instructions:

• If there are 8 hours or more until the next normal dose: take the missed prolonged-release tablet immediately, and continue with the normal schedule.
• If there are less than 8 hours until the next normal dose: take the missed prolonged-release tablet. Wait another 8 hours before taking the next prolonged-release tablet. Try to recover the original schedule (e.g., 8 am and 8 pm). Do not take more than one dose within an 8-hour period.

Do not take a double dose to make up for missed doses.

If you stop taking Oxicodona/Naloxona Viatris

Do not stop taking this medication without consulting your doctor.

If you no longer need to continue treatment, you should gradually reduce the daily dose after discussing it with your doctor. This will help you avoid withdrawal symptoms, such as restlessness, sweating, and muscle pain.

If you have any other questions about using this medication, ask your doctor or pharmacist.
