Tramadol is an analgesic belonging to the opioid group that acts on the central nervous system. It relieves pain by acting on specific nerve cells in the spinal cord and brain.

Tramadol Retard is indicated for the treatment of moderate to intense pain.

Do not take Tramadol Retard Combix

• If you are allergic (hypersensitive) to tramadol or any of the other components of Tramadol Retard Combix.
• In case of acute intoxications caused by alcohol, sleep-inducing drugs, analgesics, or psychotropic substances (medicines that act on the mood and emotions).
• If you are also taking MAO inhibitors (certain medicines used for the treatment of depression) or if you have taken them in the last 14 days before starting treatment with Tramadol Retard Combix (see "Use of other medicines").
• If you have epilepsy and your seizures are not adequately controlled with treatment.
• As a treatment for withdrawal syndrome.

Be especially careful with Tramadol Retard Combix

• If you think you have dependence on other analgesics (opioids).
• If you experience disorders of consciousness (if you think you are going to faint).
• If you are in a state of shock (a sign of this state may be cold sweat).
• If you have an increase in pressure within the skull (for example, after a head trauma or brain disease).
• If you have difficulty breathing.
• If you are epileptic or have seizures, because the risk of these seizures may increase.
• If you have any liver or kidney disease.
• If you suffer from depression and are taking antidepressants, as they may interact with tramadol (see "Use of other medicines").

Please consult your doctor before taking the medication in such cases.

Warnings and precautions

Tramadol is metabolized in the liver by an enzyme. Some people have a variation of this enzyme and this may affect each person differently. In some people, it may be possible to achieve insufficient relief from pain, while others may be more likely to experience severe adverse effects. If you notice any of the following adverse effects, you should stop taking this medication and consult a doctor immediately: slow or shallow breathing, confusion, drowsiness, constricted pupils, general discomfort or vomiting, constipation, loss of appetite.

Seizures have been reported in patients taking tramadol at the recommended dose. The risk may increase when the tramadol dose exceeds the recommended daily limit (400 mg).

Tolerance, dependence, and addiction

This medication contains tramadol, which is an opioid medication. Repeated use of opioids can make the medication less effective (the body becomes accustomed to it, known as pharmacological tolerance). Repeated use of tramadol can also lead to 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 sense of lack of control over the amount of medication 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 tramadol may be higher if:

• Youor any member of your family have abused alcohol or experienced dependence on it, prescription medications, or illegal drugs ("addiction").
• You are a smoker.
• You have had any problems with mood (depression, anxiety, or personality disorder) or have followed treatment with a psychiatrist for other mental health conditions.

If you notice any of the following symptoms while using tramadol, it could be a sign of dependence or addiction:

• You need to use the medication for a longer period than indicated by your doctor.
• You need to use a higher dose than recommended.
• You are using the medication for reasons other than those prescribed, for example, "to feel calm" or "to help you sleep".
• You have made repeated and unsuccessful attempts to stop using the medication or control its use.
• You feel unwell when you stop using the medication, and you feel better once you take it again ("withdrawal symptoms").

If you notice any of these signs, consult your doctor to determine the best course of treatment for you, when it is appropriate to discontinue the medication, and how to do it safely (see section 3, if you interrupt treatment with Tramadol Retard Combix).

Respiratory disorders related to sleep

Tramadol Retard Combix 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). Among the symptoms may include pauses in breathing during sleep, nocturnal awakenings due to lack of breath, difficulty maintaining sleep, or excessive daytime somnolence. If you or someone else observes these symptoms, contact your doctor. Your doctor may consider reducing the dose.

Consult your doctor or pharmacist if you experience any of the following symptoms while taking Tramadol Retard Combix:

Extreme fatigue, loss of appetite, severe abdominal pain, nausea, vomiting, or low blood pressure. They may be indicators of adrenal insufficiency (low cortisol levels). If you have these symptoms, contact your doctor, who will decide if you need to take hormone supplements.

Also, inform your doctor if any of the following problems occur during treatment with Tramadol Retard Combix or if they have occurred at any time

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 in monotherapy. Consult your doctor immediately if you experience any of the symptoms linked to this severe syndrome (see section 4 "Possible adverse effects").

Children and adolescents

Use in children with respiratory problems

Tramadol is not recommended for use in children with respiratory problems, as the symptoms of tramadol toxicity may worsen in these children.

Use of other medicines

Inform your doctor or pharmacist if you are using or have recently used other medications, even those purchased without a prescription.

It is recommended to avoid simultaneous treatment of Tramadol Retard Combix with monoamine oxidase inhibitors (MAOIs) (certain medications for the treatment of depression).

The analgesic effect of Tramadol Retard Combix, as well as its duration, may be reduced if you take medications that contain:

• Carbamazepine (for epilepsy seizures)
• Pentazocine, nalbuphine, or buprenorphine (analgesics);
• Ondansetron (medication to prevent nausea)

Your doctor will indicate if you should take Tramadol Retard Combix and at what dose.

The risk of adverse effects increases,

• If you take tranquilizers, sleep-inducing drugs, other analgesics such as morphine and codeine (also when used for cough), and alcohol while taking Tramadol Retard Combix. It may cause more sleepiness or the sensation of fainting. If this occurs, consult your doctor.

• If you are taking medications that may cause seizures, such as some antidepressants. The risk of seizures may increase if you take Tramadol Retard Combix at the same time. Your doctor will tell you if Tramadol Retard Combix is suitable for you.

• If you are taking selective serotonin reuptake inhibitors (SSRIs) or MAO inhibitors (medications used for the treatment of depression). Tramadol Retard Combix may interact with them and may lead to a serotonin syndrome (see section 4 "Possible adverse effects").

• If you take anticoagulant coumarins (medications that prevent abnormal blood coagulation), such as warfarin, along with Tramadol Retard Combix. The effect of these medications on blood coagulation may be affected and may lead to bleeding.

• If you take gabapentin or pregabalin for treating epilepsy or pain due to nerve problems (neuropathic pain).
