1. What is Edunix and what is it used for

Edunix is a strong pain reliever belonging to a group of medicines called opioid analgesics.

The tablets are used to treat severe pain.

2. What you need to know before you take Edunix

Do not take Edunix:

• if you are allergic to hydromorphone hydrochloride or any of the other ingredients of this medicine (listed in section 6);
• if you have breathing problems (respiratory depression or severe chronic obstructive pulmonary disease);
• if you have a severe and persistent airway disorder with narrowing of the airways (e.g. severe asthma);
• in case of loss of consciousness (coma);
• if you have stomach problems or unexpected abdominal pain (acute abdomen);
• if you have a condition where there is a lack of movement in the intestines (paralytic ileus);
• if you are taking monoamine oxidase inhibitors (MAOIs - medicines for treating depression), or if you have taken this type of medicine in the last 2 weeks.

Warnings and precautions

Talk to your doctor or pharmacist before you start taking Edunix if any of the following apply to you:

• if you or a member of your family 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 illnesses;

• alcohol addiction or a severe reaction to stopping alcohol consumption (delirium tremens);
• increased intracranial pressure or head injury;
• a condition that causes seizures, such as epilepsy;
• a mental disorder called toxic psychosis;
• low blood pressure with low blood volume (hypovolemia);
• decreased consciousness, with dizziness or fainting;
• biliary problems, biliary colic, or kidney problems (colic);
• pancreatitis (inflammation of the pancreas);
• intestinal problems, including inflammation, constriction, or obstruction of the intestine;
• enlarged prostate, causing difficulty urinating (prostatic hypertrophy);
• reduced function of the adrenal gland (e.g. Addison's disease). Your doctor will need to monitor your blood cortisol levels;
• underactive thyroid (hypothyroidism);
• breathing problems (such as chronic obstructive pulmonary disease or reduced respiratory capacity like asthma);
• elderly or frail patients;
• severe kidney or liver problems.

If you have or have had any of the above conditions or symptoms, consult your doctor as you may need a lower dose of the medicine.

Abuse and dependence

Hydromorphone - like other strong pain relievers - has a potential for abuse. Repeated use of this medicine can lead to the development of psychological or physical dependence and abuse, which can lead to a potentially fatal overdose. It is essential that you inform your doctor if you think you may have developed dependence on this medicine. Therefore, patients with current or past history of alcohol or drug abuse should use Edunix with special caution.

Sudden interruption of therapy may cause a withdrawal syndrome. If treatment with hydromorphone is no longer necessary, it may be advisable to gradually reduce the daily dose to avoid withdrawal symptoms.

Tolerance

This medicine contains hydromorphone, which is an opioid. Repeated use of opioid analgesics can reduce the effectiveness of the drug (your body gets used to the drug). This leads to the use of higher doses to achieve the desired pain relief. There may be cross-tolerance to other opioids; this means that when taking another opioid, you may also get used to that opioid.

Increased sensitivity to pain

Rarely, with the use of high doses, an increased sensitivity to pain (hyperalgesia) may occur, which will not respond to an additional increase in the dose of hydromorphone. In this case, your doctor will modify the treatment individually.

Respiratory disorders related to sleep

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

Surgery

The use of Edunix is not recommended before or during the first 24 hours after surgery. After this time, Edunix should be used with caution, especially after abdominal surgery.

Paralysis of intestinal motility

Edunix should not be used in situations where paralysis of intestinal motility (paralytic ileus) may occur. If paralytic ileus is suspected or occurs during use, treatment with hydromorphone should be discontinued immediately.

Additional pain therapy

If you are going to undergo additional pain therapy (e.g. surgery, plexus block), you should not take hydromorphone during the 24 hours prior to surgery. From then on, the dose will be adjusted, which your doctor will take care of if necessary.

Switching to another opioid

You should be aware that once an effective dose of a particular opioid (a group of strong pain relievers to which Edunix belongs) has been applied, you should not be switched to another opioid without a medical evaluation and careful reassessment based on your needs. Otherwise, continuous pain relief will not be guaranteed.

Adrenal insufficiency

If your adrenal gland is not functioning properly (adrenal insufficiency), your doctor may want to monitor your plasma cortisol concentration and prescribe appropriate medications (corticosteroids).

Interference with normal hormone production

Edunix may interfere with the normal production of hormones produced by your body (such as cortisol or sex hormones). This can happen especially after taking high doses for long periods of time.

Note

The prolonged-release tablets should never be crushed and injected, as this could lead to serious side effects, with a fatal outcome.

Use in athletes

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

Children

The use of this medicine is not recommended in children under 12 years of age. No clinical studies have been conducted on the use of hydromorphone in children.

Other medicines and Edunix

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

Concomitant use of Edunix and sedative medicines such as benzodiazepines (which can help reduce anxiety and seizures, relax muscles, and induce sleep) increases the risk of drowsiness, breathing difficulties (respiratory depression), and coma, and can be potentially fatal. Therefore, concomitant use should only be considered when other treatment options are not possible. Concomitant use of opioids and drugs used to treat epilepsy, nerve pain, or anxiety (gabapentin and pregabalin) increases the risk of opioid overdose and respiratory depression, and can be potentially fatal.

However, if your doctor prescribes Edunix together 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 the recommended dose carefully as prescribed by your doctor. 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 such symptoms.

When taken with other medicines that depress brain function or alcohol, they can increase the side effects of hydromorphone or the other medicine, such as drowsiness or impaired respiratory function.

Such depressant medicines are:

• medicines for treating anxiety (e.g. tranquilizers);
• muscle relaxants (e.g. barbiturates);
• medicines for treating psychiatric or mental disorders (neuroleptics);
• medicines to help you sleep (e.g. hypnotics or sedatives);
• medicines for treating depression (antidepressants);
• medicines for treating allergies, dizziness, or nausea (antihistamines or antiemetics);
• other strong pain relievers (opioids). There may be cross-tolerance with other opioids. If you also take other strong pain relievers (opioids), you may develop tolerance to these pain relievers.

Do not take Edunix if you are taking medicines for treating depression called monoamine oxidase inhibitors (MAOIs) or during the 2 weeks after stopping these medicines (see section 2 "Do not take Edunix").

Concomitant use of hydromorphone with certain muscle relaxants (called muscle relaxants, which are usually injected or taken orally in the form of tablets) may lead to increased breathing difficulties (respiratory depression).

Taking Edunix with alcohol

Drinking alcohol while taking this medicine 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 Edunix.

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

The use of Edunix is not recommended during pregnancy unless your doctor has specifically advised you to do so. There is limited or no data on the use of hydromorphone in pregnant women. If Edunix is administered during pregnancy, it may affect uterine contractions. Additionally, there is a risk of breathing difficulties (respiratory depression) in the newborn.

Newborns may suffer from withdrawal syndrome (such as loud crying, tremors, convulsions, lack of appetite, and diarrhea) if their mothers have taken hydromorphone for a prolonged period during pregnancy.

Breastfeeding

Hydromorphone can pass into breast milk. Therefore, Edunix should not be used during breastfeeding. If its use is necessary, breastfeeding should be discontinued.

Driving and using machines

Hydromorphone has a moderate influence on the ability to drive and use machines. These effects are more noticeable at the start of treatment with hydromorphone, after increasing the dose, or changing medication. This is also likely if you combine Edunix with alcohol or other central nervous system depressants. If you are stabilized on a specific dose, you may not be affected necessarily. Therefore, you should consult your doctor to see if you are allowed to drive or use machinery.

Edunix contains sucrose

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

Edunix contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per prolonged-release tablet; this is essentially "sodium-free".

3. How to Take Edunix

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

The dose depends on the severity of your pain and your previous needs for analgesics.

Adults and Adolescents Over 12 Years

Unless your doctor indicates otherwise, the initial dose in adults and adolescents over 12 years of age is 8 mg once a day (every 24 hours).

Important Note: The daily dose of Edunix should not be administered more than once every 24 hours and should be taken approximately at the same time every day. The dose should not be increased in intervals of less than 2 days.

If adequate pain relief is not achieved, your doctor will increase the dose. In general, the minimum effective dose to relieve pain will be chosen for each individual case.

If you think the action of this medication is too strong or too weak, inform your doctor.

Once an effective dose of Edunix has been adjusted, it should not be changed to other strong analgesics (opioid analgesic preparations). Clinical evaluation and careful dose adjustment by your doctor will be necessary. Otherwise, continuous pain relief is not guaranteed.

Elderly Patients

Elderly patients may require a lower dose to achieve adequate analgesia.

Patients with Hepatic or Renal Insufficiency

If you have renal or hepatic insufficiency, inform your doctor, as you may need lower doses to achieve pain control. Therefore, your dose of hydromorphone should be adjusted with special care. The administration of this medication is not recommended in patients with severe hepatic insufficiency.

Use in Children

The use of this medication is not recommended in children under 12 years of age. Clinical studies on the use of Edunix in children have not been conducted. Therefore, a recommended dose for this patient population cannot be provided. The dose will depend on the intensity of the pain and the patient's previous history of analgesic needs.

Method of Administration Oral.

Swallow the prolonged-release tablets whole with a sufficient amount of liquid (half a glass of water). The prolonged-release tablets should not be divided, chewed, or crushed, as this may lead to rapid release of hydromorphone and symptoms of overdose (see "If you take more Edunix than you should").

How to Open the Child-Resistant Blister1. Cut a single dose along the perforation line of the blister.

1. Pull on the non-sealed part of the label to detach the aluminum cover.

Duration of Treatment

You should not take this medication for longer than necessary.

Your treatment should be regularly reevaluated with respect to pain relief and other effects, in order to achieve optimal pain treatment and consider the continuation of treatment.

If You Take More Edunix Than You Should

If you have taken more prolonged-release tablets than prescribed, inform your doctor immediately. In case of overdose or accidental ingestion, consult your doctor or call the Toxicology Information Service; Telephone 91 562 04 20, indicating the medication and the amount taken.

The following symptoms may occur: constricted pupils (miosis), slow heartbeat (bradycardia), depressed breathing (respiratory depression), decrease in blood pressure (hypotension), and increased drowsiness (somnolence) progressing to stiffness (stupor) or loss of consciousness (coma). Patients may develop pneumonia (possible symptoms: difficulty breathing, cough, and fever) caused by inhalation of vomit or solids.

In severe cases of circulatory collapse or deep unconsciousness (coma), it may cause death.

Under no circumstances should you expose yourself to situations that require high concentration, such as driving a car.

In case of overdose, the following measure may be advisable until the doctor arrives: stay awake, give breathing instructions, provide respiratory assistance.

If You Miss a Dose of Edunix

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

If you take a lower dose than indicated or if you forget to take a prolonged-release tablet, consequently, pain relief will be insufficient or will cease completely. If you miss a dose, you can take it immediately and start a new 24-hour schedule. In principle, you should not take more than 1 Edunix prolonged-release tablet every 24 hours.

If You Interrupt Treatment with Edunix

Do not stop taking this medication without consulting your doctor. If you stop taking Edunix after prolonged use, you may experience withdrawal symptoms (e.g., agitation, anxiety, nervousness, difficulty sleeping, involuntary movements, tremors, and gastrointestinal discomfort). If therapy is no longer necessary, treatment should be gradually discontinued by reducing the dose.

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

4. Possible Adverse Effects

Like all medications, this medication can cause adverse effects, although not all people experience them.

Adverse Effects or Signs to Consider and Measures to Take When These Adverse Effects or Signs Appear:
