6. Contents of the pack and additional information

Tradonal retard belongs to a group of medications called analgesics, commonly known as pain-relieving medications. The active substance, tramadol hydrochloride, interrupts the pain messages sent to the brain and also acts on the brain to prevent the pain messages from being felt. This means that the medication does not prevent the pain from occurring, but rather you will not be able to feel the pain as much.

Tradonal retard is used to relieve moderate to severe pain (for example, pain after surgery, or after an injury).

Do not take Tradonal retard

• if you are allergic to the active ingredient or any of the other components of this medicine (listed in section 6), which have caused a skin rash, swelling of the face, or difficulty breathing
• if you are taking, or have taken in the last two weeks, monoamine oxidase inhibitors (MAOIs) to treat your depression (see section 2, “Other medicines and Tradonal retard”)
• if you have uncontrolled epilepsy
• if you have drunk enough alcohol to feel dizzy or have drunk
• if you have taken more than the prescribed dose of your sleeping pills, antipsychotics, antidepressants (antipsychotics and antidepressants are medicines that affect behavior and emotions), or other analgesics, which may reduce your ability to breathe and react

Warnings and precautions

Consult your doctor or pharmacist before starting to take Tradonal retard:

• if you have had an allergic reaction to any similar medicine to morphine

• if you have been taking this medicine or any other medicine containing tramadol for a long time
• if you have severe liver or kidney problems
• if you have recently had a head injury or have a severe headache that makes you feel unwell
• if you have had seizures (fits) or suffer from epilepsy
• if you have asthma or respiratory problems
• if you are about to undergo surgery that requires general anesthesia
• if you suffer from depression and are taking antidepressants, as some may interact with tramadol (see “Other medicines and Tradonal retard”).

Respiratory problems related to sleep

This medicine may cause respiratory problems related to sleep, such as central sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). These 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 experience any of the following symptoms while taking Tradonal retard:

Extreme fatigue, loss of appetite, severe abdominal pain, nausea, vomiting, or low blood pressure. This may indicate that you have adrenal insufficiency (low cortisol levels). If you experience any of these symptoms, inform your doctor, who will decide whether you should take a hormone supplement.

There is a rare possibility that this medicine may cause seizures (fits). This risk increases if you take doses higher than the maximum daily dose and also take antidepressants or antipsychotics.

Tolerance, dependence, and addiction

This medicine contains tramadol, which is an opioid medicine. Repeated use of opioids can make the medicine less effective (your body becomes accustomed to it, known as pharmacological tolerance). Repeated use of this medicine can also cause dependence, abuse, and addiction, which could lead to a potentially fatal overdose. The risk of these adverse effects may be higher with a higher dose and longer use.

Dependence or addiction can cause a feeling of loss of control over the amount of medicine you should use or the frequency with which you should use it.

The risk of dependence or addiction varies from person to person. The risk of becoming dependent or addicted to this medicine may be higher if:

If you observe any of the following symptoms while using this medicine, it could be a sign of dependence or addiction:

If you notice any of these signs, consult your doctor to determine the best course of treatment for you, when it is appropriate to stop taking the medicine, and how to do it safely (see section 3, if you interrupt treatment with Tradonal retard).

You should not take this medicine to treat withdrawal symptoms in the case of addiction to other medicines.

There is a weak risk that you may experience a serotonin syndrome that can occur after taking tramadol in combination with certain antidepressants or tramadol alone. Consult your doctor immediately if you experience any of the symptoms linked to this serious syndrome (see section 4 “Possible side effects”).

Tramadol is metabolized in the liver by an enzyme. Some people have a variation of this enzyme, and this can affect each person differently. In some people, you may not get enough pain relief, while others are more likely to experience severe adverse effects. If you experience any of the following adverse effects, stop taking this medicine and consult your doctor immediately: shallow or slow breathing, confusion, drowsiness, constricted pupils, feeling dizzy, constipation, loss of appetite.

In rare cases, increasing the dose of this medicine may make you more sensitive to pain. If this happens, talk to your doctor about your treatment.

Children and adolescents

This medicine should not be used in children under 12 years old.

Use in children with respiratory problems

Tramadol should not be used in children with respiratory problems, as the symptoms of tramadol toxicity may worsen in these children.

Other medicines and Tradonal retard

Inform your doctor or pharmacistifyou are taking, have taken recently, or may need to take any other medicine, including those purchased without a prescription.

Do not take Tradonal retard at the same time, or during the 14 days after taking medicines called monoamine oxidase inhibitors (moclobemide or phenelzine for depression, selegiline for Parkinson's disease).

The pain relief produced by tramadol may be weakened or shortened if you also take medicines that contain:

Your doctor will tell you if you should take this medicine and at what dose.

The risk of adverse effects increases if you are taking medicines that facilitate or may cause seizures, such as certain antidepressants or antipsychotics. The risk of seizures increases if you take Tradonal retard at the same time as these medicines. Your doctor will tell you if it is suitable for you.

The risk of adverse effects increases if you are taking antidepressants. Tradonal retard may interact with these medicines and you may experience a serotonin syndrome(see section 4 “Possible side effects”).

Medicines that act on the nervous system, such as hypnotics, tranquilizers, sleeping pills, and analgesics, may make you feel more sleepy or weak if you use them with tramadol.

The risk of adverse effects increases if you are taking gabapentin or pregabalin to treat epilepsy or nerve pain (neuropathic pain).

Anticoagulants to thin your blood, such as warfarin. The effectiveness of these medicines may be altered if you take them with tramadol.

You should inform your doctor if you are taking these medicines.

The concomitant use of tramadol with sedatives, such as benzodiazepines or related substances, increases the risk of somnolence, respiratory difficulties (respiratory depression), and coma and could be potentially fatal. Therefore, concomitant use should only be considered when other options are not possible.

However, if your doctor prescribes Tradonal retard with sedatives, the dose and duration of concomitant treatment will be limited by your doctor.

Inform your doctor of all sedatives you are taking and take exactly the dose your doctor recommends. It is helpful to inform your friends or family members to be aware of the appearance of the signs and symptoms explained above. Contact your doctor if you experience these symptoms.

This medicine should be taken with a little water, with or without food. Avoid drinking alcohol while taking this medicine.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, consult your doctor or pharmacist before using this medicine. Contact your doctor if you become pregnant during your treatment.

Pregnancy

Tradonal retard should not be taken during pregnancy or during breastfeeding. This is because it is not yet known how safe it is to take this medicine when pregnant. Contact your doctor if you become pregnant during your treatment.

Breastfeeding

Tramadol is excreted in breast milk. Therefore, you should not take Tradonal retard more than once during breastfeeding, or if you take this medicine more than once, you should stop breastfeeding.

Driving and operating machinery

Tradonal retard may cause drowsiness, and this effect may be potentiated by alcohol, antihistamines, and other central nervous system depressants. If patients are affected, they should be advised not to drive or operate machinery.

Tradonal retard contains saccharose

The dose should be adjusted to the intensity of the pain and your individual sensitivity to pain. Normally, the lowest dose that produces pain relief should be taken.

The modified-release capsules of Tradonal retard are packaged in a child-resistant laminate to ensure safety.

The child-resistant laminate is more resistant, making it more difficult to push the capsules through it.

Perforate the laminate beforehand and then push the capsule to remove it from the blister, in order to avoid damaging the capsules.

Swallow the capsules whole, without chewing, with a little water.

If you have difficulty swallowing the capsules, you can open them. You must open them carefully, pulling and turning at the same time, over a spoon, so that the granules remain on the spoon. Do not chew them. Swallow the granules with water.

Dose for adults and adolescents 12 years and older

The usual initial dose is 50-100 mg twice a day, in the morning and at night. Your doctor may increase this dose to 150-200 mg twice a day, according to the intensity of the pain and your needs. Normally, you should take the medication every 12 hours, at the same time in the morning and at night.

Theusual maximumdose is 400 mg per day.

Use in children

This medication should not be administered to children under 12 years old.

Use in elderly patients

In elderly patients (over 75 years old), the elimination of tramadol may be slow. If this happens, your doctor may recommend increasing the interval between doses.

Use in patients with liver or kidney disease/patients on dialysis
