6. Contents of the pack and additional information

Targin is a prolonged-release tablet, meaning that its active ingredients are released over a prolonged period of time. Its action lasts 12 hours.

These tablets are only for use in adults.

Pain relief

You have been prescribed Targin for the treatment of intense pain, which can only be adequately treated with opioid analgesics. Hydrochloride of naloxone has been added to counteract constipation.

How these tablets work for pain relief

These tablets contain as active ingredients hydrochloride of oxycodone and hydrochloride of naloxone. Hydrochloride of oxycodone is responsible for the analgesic effect of Targin; it is a potent opioid analgesic. The second active ingredient of Targin, hydrochloride of naloxone, has the function of counteracting constipation. Intestinal dysfunction (e.g. constipation) is a common adverse effect of treatment with opioid analgesics.

Restless legs syndrome

You have been prescribed Targin for symptomatic treatment of second-line in patients with severe to very severe idiopathic restless legs syndrome, which cannot be treated with dopaminergic drugs. People with restless legs syndrome feel an unpleasant sensation in their limbs. This can start as soon as they sit or lie down and is only relieved by an urgent and irresistible movement of the legs, sometimes the arms and other parts of the body. This makes it very difficult to stay seated and sleep. Hydrochloride of naloxone has been added to counteract constipation.

How these tablets work in restless legs syndrome

These tablets help to relieve unpleasant sensations, and therefore, reduce the urgent need to move the limbs.

The second active ingredient of Targin, hydrochloride of naloxone, has the function of counteracting constipation. Intestinal dysfunction (e.g. constipation) is a common adverse effect of treatment with opioid analgesics.

Do not take Targin

- if you are allergic to oxycodone hydrochloride, naloxone hydrochloride, or any of the other ingredients of this medicine (listed in section 6),

- if you have difficulty breathing and are unable to get enough oxygen into your blood or remove carbon dioxide from your 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 condition called cor pulmonale. This condition is characterized by an increase in the size of the right side of the heart due to increased pressure in the blood vessels of the lungs, etc. (for example, 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 disease.

Additionally for restless legs syndrome

- if you have a history of opioid abuse.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Targin:

- if you are an elderly or debilitated patient,

- if you have paralytic ileus (a type of intestinal obstruction) caused by opioids,

- if you have kidney disease,

- if you have mild liver disease,

- if you have severe lung disease (i.e., reduced ability to breathe),

- if you have a condition characterized by frequent pauses in breathing during sleep, which can make you feel very drowsy during the day (sleep apnea),

- if you have hypothyroidism (a condition where the thyroid gland does not produce enough hormones),

- if you have adrenal insufficiency (a condition where the adrenal glands do not produce enough hormones),

- if you have a mental disorder accompanied by a loss (partial) of reality (psychosis), due to alcoholism or intoxication by other substances (substance-induced psychosis),

- if you have gallstones,

- if you have an enlarged prostate (prostatic 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 a previous cardiovascular disease,

- if you have a head injury (due to the risk of increased intracranial pressure),

- 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), or have taken this type of medication in the past two weeks, for example, medications containing tranilcipromina, phenelzine, isocarboxazide, moclobemide, and linezolid,

- if you experience drowsiness or sudden episodes of sleep.

Respiratory disorders related to sleep

Targin may cause respiratory disorders related to sleep such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low levels of oxygen in the blood). Symptoms may include pauses in breathing during sleep, nocturnal awakenings due to difficulty breathing, difficulty maintaining sleep or excessive daytime somnolence. If you or someone else observes these symptoms, consult your doctor. Your doctor may consider reducing the dose.

Inform your doctor if you have had any of these conditions in the past. Also, inform your doctor if you develop any of them during treatment with these tablets.

The most severe consequence of opioid overdose is respiratory depression (slow and shallow breathing). This can also cause a decrease in oxygen concentration in the blood, which can lead to fainting, etc.

Swallow the prolonged-release tablet whole, so that it does not affect the slow release of oxycodone hydrochloride from the prolonged-release tablet. Do not break, chew, or crush the tablets. Taking them broken, chewed, or crushed may lead to potentially fatal absorption of oxycodone hydrochloride (see section 3 "If you take more Targin than you should").

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

If you have been receiving another opioid, you may experience withdrawal symptoms shortly after starting treatment with Targin, for example, restlessness, sweating, and muscle pain. If you experience any of these symptoms, you may need special monitoring by your doctor.

Tolerance, dependence, and addiction

This medicine contains oxycodone, which is an opioid medication. Repeated use of opioid analgesics can make the medication less effective (you become accustomed to it, known as tolerance). Repeated use of Targin may also cause dependence, abuse, and addiction, which can lead to a overdose that puts your life at risk. The risk of these adverse effects may increase with a higher dose and longer duration of use.

Dependence or addiction may make you feel that 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 that you need to continue taking the medication, even when it no longer helps to relieve your pain or restless legs syndrome.

The risk of becoming dependent or addicted to Targin varies from person to person. You may have a higher risk of becoming dependent or addicted to Targin:

- if you or a family member has a history of abuse or dependence on alcohol, prescription medications, or illicit substances ("addiction").

- if you smoke.

- if you have ever had problems with your mood (depression, anxiety, or a personality disorder) or have received treatment from a psychiatrist for other mental health conditions.

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

– You need to take the medication for longer than recommended by your doctor.

– You need to take more doses than recommended.

– You are using the medication for reasons other than those prescribed, for example, "to stay calm" or "to help you sleep".

– You have made repeated and unsuccessful attempts to stop or control the use of the medication.

– 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 analyze the best treatment for you, including when it is appropriate to stop taking it and how to do it safely (see section 3, If you interrupt treatment with Targin).

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

Inform your doctor if you have cancer associated with peritoneal metastases or initial intestinal obstruction in advanced stages of digestive and pelvic cancers.

If you need to undergo surgery, tell the doctors that you are taking Targin.

Like other opioids, oxycodone can affect the normal production of hormones in the body, such as cortisol or sex hormones, especially if you have to take high doses for long periods of time. If you notice persistent symptoms such as discomfort (including vomiting), loss of appetite, fatigue, weakness, dizziness, changes in menstrual cycle, impotence, infertility, or decreased libido, consult your doctor to monitor your hormone levels.

This medicine may increase your sensitivity to pain, especially at high doses. Inform your doctor if this occurs. You may need to reduce the dose or change the medication.

You may observe remnants of the prolonged-release tablet in your stool. Do not be alarmed, as the active principles (oxycodone hydrochloride and naloxone hydrochloride) have already been released in the stomach and intestine and have been absorbed by your body.

Incorrect use of Targin

These tablets are not a treatment for withdrawal symptoms.

You should never abuse Targin, especially if you have a substance abuse problem. If you are addicted to substances such as heroin, morphine, or methadone, you may experience severe withdrawal symptoms if you misuse these tablets, as they contain naloxone. They may worsen existing withdrawal symptoms.

You should never dissolve these tablets to inject them (for example, 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.

The use of Targin may result in positive tests in antidoping controls. The use of Targin as a doping agent may put your health at risk.

Taking Targin with other medications

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

The risk of adverse effects increases if you use antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, and venlafaxine). These medications may interact with oxycodone and you may experience 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.

The concomitant use of opioids, including oxycodone hydrochloride, and sedatives such as benzodiazepines or related medications increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and may put your life at risk. Therefore, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor prescribes Targin along with sedatives, your doctor should limit the dose and duration of concomitant treatment.

Inform your doctor of all sedatives you are taking and follow the recommended doses 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. Examples of sedatives or related medications include:

• other potent analgesics (opioids);

• medications to treat epilepsy, pain, and anxiety, such as gabapentin and pregabalin;

• sleep aids and tranquilizers (sedatives, including benzodiazepines, hypnotics, anxiolytics);

• medications to treat depression;

• medications used to treat allergies, dizziness, or nausea (antihistamines or antiemetics);

• medications to treat psychiatric or mental disorders (antipsychotics that include phenothiazines and neuroleptics);

• muscle relaxants;

• medications to treat Parkinson's disease.

If you take these tablets at the same time as other medications, the effects of the tablets or the other medications described below may change. Inform your doctor if you are taking:

• medications that reduce blood clotting (coumarin derivatives), the speed of clotting may increase or decrease;

• macrolide antibiotics (such as clarithromycin, erythromycin, or telithromycin);

• azole antifungals (such as ketoconazole, voriconazole, itraconazole, or posaconazole);

• a specific type of medication known as a protease inhibitor used to treat HIV (for example, ritonavir, indinavir, nelfinavir, or saquinavir);

• cimetidine (a medication to treat stomach ulcers, indigestion, or acid reflux);

• rifampicin (used to treat tuberculosis);

• carbamazepine (used to treat seizures or convulsions and certain painful conditions);

• phenytoin (used to treat seizures or convulsions);

• a medicinal plant called St. John's Wort (also known as Hypericum perforatum);

• quinidine (a medication to treat arrhythmias).

No interactions are expected between Targin and paracetamol, acetylsalicylic acid, or naltrexone.

Taking Targin with food, drinks, and alcohol

Drinking alcohol while taking Targin may make you feel more drowsy or increase the risk of severe adverse effects such as shallow breathing with the risk of stopping breathing, and loss of consciousness. It is recommended not to drink alcohol while taking Targin.

You should avoid drinking grapefruit juice while taking these tablets.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, consult your doctor or pharmacist before using this medication.

Pregnancy

During pregnancy, these tablets should be avoided as much as possible. If they are used during prolonged periods of pregnancy, oxycodone hydrochloride may cause withdrawal symptoms in the newborn. If oxycodone hydrochloride is administered during delivery, the newborn may experience respiratory depression (slow and shallow breathing).

Breastfeeding

Stop breastfeeding during treatment with these tablets. 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 several doses of Targin.

Driving and operating machinery

Targin may affect your ability to drive and operate machinery. This occurs especially at the beginning of treatment with Targin, after an increase in dose, or after switching from another medication. However, these adverse effects disappear once the dose of Targin is established.

Targin has been associated with drowsiness and sudden episodes of sleep. If you experience these adverse effects, you should not drive or operate machinery. If this occurs, inform your doctor.

Ask your doctor if you can drive or operate machinery during treatment with Targin.

Targin contains lactose

This medication contains lactose (milk sugar). If your doctor has told you that you have a intolerance to certain sugars, consult with them before taking this medication.

Follow exactly the administration instructions of this medication as indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

Before starting treatment and periodically during treatment, your doctor will discuss with you what you can expect from the use of Targin, when and for how long you should take it, when to contact your doctor, and when to stop taking it (see also "If you interrupt treatment with Targin").

Targin is a prolonged-release tablet, meaning that the active ingredients are released over a prolonged period of time. Its action lasts 12 hours.

You must swallow the prolonged-release tablet whole to avoid affecting the slow release of hydrochloride of oxicodone from the tablet.Do not break, crush, or chew the tablets.If you do, your body may absorb a potentially fatal dose of hydrochloride of oxicodone (see section 3 "If you take more Targin than you should").

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

For pain treatment

Adults

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

Your doctor will decide the dose you should take per day and how to divide the total daily dose between the morning dose and the evening dose. Your doctor will also decide if it is necessary to adjust the dose during treatment. Your dose will be adjusted according to your level 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 Targin may be higher.

The maximum daily dose is 160 mg of hydrochloride of oxicodone and 80 mg of hydrochloride of naloxone. If you need a higher dose, your doctor may prescribe more hydrochloride of oxicodone without hydrochloride of naloxone. However, the maximum daily dose of hydrochloride of oxicodone should not exceed 400 mg. The beneficial effect of hydrochloride of naloxone on intestinal activity may be affected if the dose of hydrochloride of oxicodone is increased without increasing the dose of hydrochloride of naloxone.

If you substitute these tablets with another opioid analgesic, it is likely that your intestinal function will worsen. If you experience pain between two doses of Targin, you may need a rapid-acting analgesic. Targin is not suitable for treatment in this case. Discuss this with your doctor.

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

For restless legs syndrome treatment

Adults

The usual initial dose is 5 mg of hydrochloride of oxicodone/2.5 mg of hydrochloride of naloxone in prolonged-release tablets every 12 hours.

Your doctor will decide how much Targin you should take each day and how to divide the total daily dose between the morning dose and the evening dose. Your doctor will also decide if it is necessary to adjust the dose during treatment. Your dose will be adjusted according to your individual response. The minimum dose necessary to mitigate the symptoms of restless legs syndrome will be chosen.

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

The maximum daily dose is 60 mg of hydrochloride of oxicodone and 30 mg of hydrochloride of naloxone.

For pain or restless legs syndrome treatment

Older adults

Generally, no dose adjustment is necessary in older adults with normal kidney and/or liver function.

Kidney or liver disorder

If you have any degree of kidney disorder or mild liver disorder, your doctor will prescribe these tablets with special caution. If you have moderate or severe liver disorder, you should not take these tablets (see also section 2 "Do not take Targin" and "Warnings and precautions").

Children and adolescents under 18 years
