Tramadol Aristo 150 mg prolonged-release tablets EFG

tramadol hydrochloride

Read this leaflet carefully before you start to take this medicine because it contains important information for you.

• Keep this leaflet, as you may need to read it again.
• If you have any questions, ask your doctor or pharmacist.
• This medicine has been prescribed for you only. Do not give it to others even if they have the same symptoms as you, as it may harm them.
• If you experience any side effects, consult your doctor or pharmacist, even if they are not listed in this leaflet. See section 4.

Tramadol, the active ingredient of this medication, is an analgesic belonging to the group of opioids that acts on the central nervous system. It relieves pain by acting on specific nerve cells in the spinal cord and brain.

Tramadol is indicated for the treatment of moderate to severe pain.

Do not take tramadol

• If you are allergic to tramadol or any of the other components of this medication (listed in section 6).
• For acute intoxications caused by alcohol, sleeping pills, painkillers, or psychotropic medications (medications that affect mood and emotions).
• If you are also taking MAO inhibitors (certain medications used to treat depression) or if you have taken them in the last 14 days before starting tramadol treatment (see "tramadol with other medications").
• If you have epilepsy and your seizures are not adequately controlled with treatment.
• For the treatment of withdrawal syndrome.

Warnings and precautions

Consult your doctor or pharmacist before starting to take tramadol, if:

• You have consciousness disorders (if you think you are going to faint).
• You are in shock (a sign of this state can be cold sweat).
• You have increased intracranial pressure (for example, after a head trauma or brain disease).
• You have difficulty breathing.
• You are epileptic or have seizures, as the risk of these seizures may increase.
• You have depression and are taking antidepressants, as some may interact with tramadol (see section "Other medications and tramadol").
• You have any liver or kidney disease.

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 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 lack of control over the amount of medication to be used or the frequency with which it is used.

The risk of dependence or addiction varies from person to person. The risk of becoming dependent

or addicted to tramadol may be higher if:

• You or any family member 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 by a psychiatrist for other mental illnesses.

If you observe any of the following symptoms while using tramadol, 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 discontinue the medication, and how to do it safely (see section 3, if you interrupt tramadol treatment).

Respiratory problems related to sleep

Tramadol contains an active ingredient that belongs to the group of opioids. Opioids can cause respiratory problems related to sleep; for example, central sleep apnea (shallow breathing or pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood).

The risk of experiencing central sleep apnea depends on the dose of opioids. Your doctor may consider reducing the total dose of opioids if you experience central sleep apnea.

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 monotherapy. Consult your doctor immediately if you experience any of the symptoms associated with this severe syndrome (see section 4 "possible adverse effects").

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

Be aware that tramadol can cause physical and psychological dependence. When this medication is used for a long period, its effect may decrease, requiring higher doses (development of tolerance).

In patients with a tendency to abuse medications or who have medication dependence, treatment with tramadol should only be carried out for short periods of time and under strict medical supervision.

Also inform your doctor if any of the following problems occur during treatment with tramadol or if they have ever occurred:

Tramadol is transformed in the liver by an enzyme. Some people have a variation of this enzyme, and this can affect each person differently. In some people, it may not be possible to achieve sufficient pain relief, while others may be more likely to experience severe adverse effects. If you notice any of the following adverse effects, 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.

Inform your doctor if you experience any of the following symptoms while taking tramadol:

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.

Tramadol with other medications

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

Simultaneous treatment with tramadol and monoamine oxidase inhibitors (MAOIs) (certain medications for depression treatment) should be avoided.

The analgesic effect and duration of tramadol may be reduced if you take medications that contain:

• Carbamazepine (for epilepsy seizures)
• Ondansetron (medication to prevent nausea)

Your doctor will indicate if you should take tramadol and at what dose.

The risk of adverse effects increases if you are taking:

• Other painkillers such as morphine and codeine (also for cough), and alcohol while taking tramadol. It may cause more sleepiness or the sensation of fainting. If this occurs, consult your doctor.

The concomitant use of tramadol with sedatives or sleep medications (such as benzodiazepines) increases the risk of drowsiness, respiratory difficulties (respiratory depression), coma, and may be potentially fatal. Therefore, concomitant use should only be considered when other treatment options are not possible. However, if your doctor prescribes this medication with sedatives, you should limit the dose and duration of concomitant treatment.

• Inform your doctor about all sedatives you are taking and strictly follow your doctor's recommended dose. It may be helpful to inform your friends and family about the signs and symptoms mentioned above. Inform your doctor if you experience any of these symptoms.

• Medications that facilitate or may cause seizures, such as certain antidepressants or antipsychotics. The risk of seizures increases if you take tramadol simultaneously with these medications. Your doctor will tell you if tramadol is suitable for you.

• Depression medications. Tramadol may interact with these medications and you may experience a serotonin syndrome (see section 4 "possible adverse effects").

• Anticoagulant coumarins (medications that prevent abnormal blood coagulation), such as warfarin, with tramadol. The effect of these medications on blood coagulation may be affected and may lead to bleeding.

• Gabapentin or pregabalin for treating epilepsy or pain due to nerve problems (neuropathic pain).

Tramadol with food and alcohol

Do not consume alcohol during tramadol treatment, as its effect may be intensified. Food does not affect the effect of tramadol.

Use in athletes

This medication contains tramadol, which may produce a positive result in doping control tests.

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.

Pregnancy, breastfeeding, and fertility

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

There is very little information available on the safety of tramadol in pregnant women. Therefore, do not take tramadol if you are pregnant.

Chronic treatment during pregnancy may lead to withdrawal syndrome in newborns.

Tramadol may pass into breast milk. Therefore, do not take tramadol more than once during breastfeeding or, if you take it more than once, discontinue breastfeeding.

Based on human experience, it is not suggested that tramadol affects male and female fertility.

Driving and using machines

Ask your doctor if you can drive or use machines during tramadol treatment. It is essential to observe how this medication affects you before driving or using machines. Do not drive or use machines if you feel drowsy, dizzy, have blurred vision, or have difficulty concentrating. Be particularly careful at the start of treatment, after increasing the dose, after changing the formulation, and/or administering it concurrently with other medications.

If you forgot to take Tramadol Aristo

If you forget to take tramadol, it is likely that the pain will recur. Do not take a double dose to compensate for the missed doses, simply continue treatment as instructed by your doctor.

If you interrupt treatment with Tramadol Aristo

If you interrupt or discontinue treatment with tramadol too soon, it is likely that the pain will recur. If you want to discontinue treatment due to undesirable effects, consult your doctor.

You should not stop taking this medication suddenly unless your doctor instructs you to do so. If you want to stop taking your medication, talk to your doctor first, especially if you have been taking it for a long time. Your doctor will inform you when and how to discontinue it, which can be done by gradually reducing the dose to reduce the likelihood of unnecessary adverse effects (withdrawal symptoms).

Generally, no adverse effects occur when discontinuing treatment with tramadol. However, in rare cases, when some people who have been taking tramadol for some time stop taking it suddenly, they may feel unwell. They may feel agitated, anxious, nervous, or shaky. They may feel hyperactive, have difficulty sleeping, or experience gastrointestinal or intestinal disorders. Very few people may experience panic attacks, hallucinations, unusual perceptions such as itching, tingling, and numbness, and ringing in the ears (tinnitus). Very rarely, other unusual central nervous system symptoms, such as confusion, delirium, distorted perception of one's own personality (derealization), and altered perception of reality (despersonalization), and delusions of persecution (paranoia), have been seen. If you experience any of these symptoms after stopping tramadol, please consult your doctor.

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