1. What OxyContin is and what it is used for

OxyContin is a strong pain reliever, also known as an analgesic, and belongs to the group of opioids.

OxyContin is used in adults and adolescents from 12 years of age for the relief of severe pain, which can only be adequately managed with opioid analgesics.

2. What you need to know before you take OxyContin

Do not take OxyContin if:

• you are allergic (hypersensitive) to oxycodone or any of the other ingredients of the tablets (listed in section 6) or have had a previous allergic reaction to other strong pain relievers (such as morphine or other opioids);
• you have breathing problems, such as chronic obstructive pulmonary disease, severe bronchial asthma, or severe respiratory depression. Symptoms may include difficulty breathing, coughing, or slow and weak breathing;
• you have a head injury that causes severe headaches or dizziness. This is because the tablets may make these symptoms worse or mask the extent of the injury;
• you have a condition where your small intestine does not function properly (paralytic ileus), your stomach empties more slowly than normal (delayed gastric emptying), or you have severe abdominal pain (acute abdomen);
• you have a heart problem after long-term lung disease (cor pulmonale).

Warnings and precautions

Consult your doctor or pharmacist before taking OxyContin if:

• you are elderly or debilitated;
• you have low thyroid function (hypothyroidism);
• you have severe headaches or dizziness, as this may indicate increased pressure in your skull;
• you have myxedema (a thyroid disorder, with dryness, coldness, and swelling of the skin, affecting the face and limbs);
• you have low blood pressure (hypotension);
• you or a family member have a history of abuse or dependence on alcohol, prescription drugs, or illicit substances ("addiction");
• you smoke;
• you have ever had problems with your mood (depression, anxiety, or personality disorder) or have received psychiatric treatment for other mental health disorders;
• you have pancreatitis (which can cause severe abdominal and back pain) or problems with your gallbladder or bile duct;
• you have intestinal obstruction or inflammatory bowel disease;
• you have abdominal colic pain or discomfort;
• you have an enlarged prostate gland, which causes difficulty passing urine (in men);
• you have poor adrenal gland function (your adrenal gland does not work properly), such as Addison's disease;
• you have respiratory problems, such as severely impaired respiratory function, chronic obstructive pulmonary disease, severe lung injury, or reduced respiratory capacity. Symptoms may include difficulty breathing and coughing;
• you have liver or kidney problems;
• you have withdrawal symptoms such as agitation, anxiety, palpitations, tremors, or sweating when stopping alcohol or drugs;
• you have seizures, fits, or convulsions;
• you feel faint or dizzy;
• you need to increase the dose of OxyContin to achieve the same level of pain relief (tolerance);
• you have increased sensitivity to pain;
• you are taking a type of medicine known as monoamine oxidase inhibitors (such as tranylcypromine, phenelzine, isocarboxazid, moclobemide, and linezolid), or if you have taken this type of medicine in the last two weeks.
• you suffer from constipation.

Breathing-related sleep disorders

OxyContin may cause breathing-related sleep disorders, such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to difficulty breathing, difficulty staying asleep, or excessive daytime sleepiness. If you or someone else notices these symptoms, consult your doctor. Your doctor may consider reducing the dose.

If you are going to have surgery, tell your doctor at the hospital that you are taking these tablets.

You may experience hormonal changes while taking this medicine. Your doctor may want to monitor these changes.

The tablets should never be crushed or injected, as this can cause serious side effects, which can be fatal.

Opioids are not the first choice for treating non-cancer pain and are not recommended as the only treatment. In the treatment of chronic pain, other medications should be used in conjunction with opioids. Your doctor should closely monitor you and make necessary adjustments to your dose while taking OxyContin to prevent addiction and abuse.

This medicine contains oxycodone, which may produce a positive result in doping tests.

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, which is known as tolerance). Repeated use of OxyContin can also 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 OxyContin:

• if you or a family member have a history of abuse or dependence on alcohol, prescription drugs, or illicit substances ("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 health disorders.

If you notice any of the following signs while taking OxyContin, 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, such as "to calm down" or "to help you sleep".
• You have made repeated 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 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 taking OxyContin).

Contact your doctor if you have severe abdominal pain in the upper abdomen that may radiate to the back, nausea, vomiting, or fever, as these may be symptoms associated with pancreatitis and the biliary system.

Taking OxyContin with other medicines

Concomitant use of opioids, including oxycodone, and sedative medicines, such as benzodiazepines or related medicines, increases the risk of drowsiness, breathing difficulties (respiratory depression), coma, and can be life-threatening. Due to this, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor prescribes OxyContin with sedative medicines, your doctor should limit the dose and duration of concomitant treatment.

Tell your doctor about all sedative medicines you are taking and follow your doctor's dose recommendation carefully. It may be useful to inform friends or family members who are aware of the signs and symptoms mentioned above. Contact your doctor when you experience these symptoms.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

If you take these tablets with some medicines, the effect of the tablets or the other medicine may be changed.

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

Tell your doctor or pharmacist if you are taking:

• medicines called monoamine oxidase inhibitors or have taken them in the last two weeks (see section "Warnings and precautions");
• medicines that help you sleep or stay calm (such as hypnotics or sedatives, including benzodiazepines);
• medicines for treating depression (such as paroxetine or fluoxetine);
• medicines for treating psychiatric or mental disorders (such as phenothiazines or neuroleptics);
• medicines for treating epilepsy, pain, and anxiety, such as gabapentin and pregabalin;
• other strong pain relievers;
• muscle relaxants;
• medicines for treating high blood pressure;
• quinidine (a medicine for treating rapid heart rhythm);
• cimetidine (a medicine for stomach ulcers, indigestion, or heartburn);
• medicines for treating fungal infections (such as ketoconazole, voriconazole, itraconazole, or posaconazole);
• medicines used to treat bacterial infections (such as clarithromycin, erythromycin, or telithromycin);
• a specific type of medicine known as protease inhibitors for treating HIV (such as boceprevir, ritonavir, indinavir, nelfinavir, or saquinavir);
• rifampicin for treating tuberculosis;
• carbamazepine (a medicine for treating seizures, fits, or convulsions and certain pain conditions);
• phenytoin (a medicine for treating seizures, fits, or convulsions);
• a herbal remedy called St. John's Wort (also known as Hypericum perforatum);
• antihistamines;
• medicines for treating Parkinson's disease.

Also, tell your doctor if you have recently been given an anesthetic.

Taking OxyContin with food, drinks, and alcohol

These tablets can be taken with or without food.

Drinking alcohol while taking OxyContin tablets may 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 OxyContin tablets.

You should avoid drinking grapefruit juice during treatment with OxyContin.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

You should not use these tablets during pregnancy and childbirth, unless your doctor has specifically advised you to do so. Depending on the dose and duration of treatment with oxycodone, the newborn may experience slow and shallow breathing (respiratory depression) or withdrawal symptoms.

Breastfeeding

You should not use these tablets while breastfeeding, as the active substance may pass into breast milk.

Driving and using machines

These tablets may cause a number of side effects, such as drowsiness, which may affect your ability to drive or use machines (see section 4 for a full list of side effects). These effects are more pronounced when starting treatment with the tablets or when increasing the dose. If affected, you should not drive or use machines.

OxyContin contains lactose

This medicine contains lactose. If your doctor has told you that you have an intolerance to some sugars, consult your doctor before taking this medicine.

3. How to Take OxyContin

Follow your doctor's instructions for taking these tablets exactly. If you are unsure, consult your doctor or pharmacist again. The labeling on your medication will tell you how to take the tablets and how often.

Before starting treatment and periodically during treatment, your doctor will discuss with you what to expect from using oxycodone, 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 treatment with OxyContin").

There are different doses available for this medication. Your doctor will decide which dose of OxyContin prolonged-release tabletsis most suitable for you.

Do not exceed the dose recommended by your doctor.

Swallow the tablets whole with a glass of water. Do not chew, crush, or dissolve them.

You should take your tablets every 12 hours. Therefore, if you take a tablet at 8 in the morning, you should take the next one at 8 in the evening. It is recommended to take this medication consistently in relation to meal times.

The tablets must not be crushed or injected because they can cause very serious side effects. These tablets should only be taken orally.

The OxyContin tablets are designed to work properly for 12 hours when taken whole. If the tablet is broken, crushed, dissolved, or chewed, the full 12-hour dose may be absorbed quickly by your body. This can be dangerous, causing serious problems such as overdose, which can be fatal.

Adults and Adolescents (12 years of age and older)

The usual initial dose is one 10 mg tablet every 12 hours. In some cases, your doctor may prescribe an initial dose of 5 mg to reduce the side effects you may experience. Your doctor will prescribe the dose needed to treat your pain. If you continue to have pain despite taking the tablets, talk to your doctor.

Children under 12 years of age

The safety and efficacy of oxycodone have not been sufficiently proven in children under 12 years of age. Therefore, treatment with oxycodone is not recommended in children under 12 years of age.

Patients with kidney and/or liver problems

Please inform your doctor if you have kidney or liver problems, so that he can prescribe an alternative medication or reduce the dose depending on your situation.

If you take more OxyContin than you should or if someone accidentally takes the tablets

Inform your doctor immediately or go to your hospital.

An overdose can cause:

• a decrease in the size of your pupils
• slower and weaker breathing than normal (respiratory depression)
• drowsiness or loss of consciousness
• a decrease in muscle tone (hypotonia)
• a decrease in pulse
• a drop in blood pressure
• difficulty breathing due to fluid in the lungs (pulmonary edema)
• a brain disorder (known as toxic leukoencephalopathy).

In some cases, an overdose can lead to unconsciousness or even death. When you need medical attention, make sure to bring this leaflet with you and the tablets you have for your doctor to see.

If you have taken too many tablets, under no circumstances should you put yourself in a situation that requires you to be alert, such as driving a car.

In case of overdose or accidental ingestion, contact the Toxicology Information Service, Phone 91 562 04 20, or go directly to the hospital.

If you forget to take OxyContin

If you forget to take a dose within 4 hours of the scheduled time, take a tablet immediately. Take your next tablet at your usual time. If the delay in taking it is more than 4 hours, consult your doctor or pharmacist. Do not take a double dose to make up for missed doses.

If you stop treatment with OxyContin

Do not suddenly stop treatment with these tablets unless your doctor tells you to do so first. If you want to stop taking this medication, talk to your doctor first. Your doctor will tell you how to do it by gradually reducing the daily dose, so you do not experience unpleasant effects. If you stop taking these tablets suddenly, you may experience withdrawal symptoms such as yawning, abnormal dilation of the pupils, lacrimation, nasal discharge, agitation, anxiety, seizures, difficulty sleeping, palpitations, tremors, or sweating.

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