Tramadol Hydrochloride/paracetamol 37.5 mg / 325 mg film-coated tablets – patient leaflet, side effects, dosage

1. What Tramadol/ Paracetamol is and what it is used for

Tramadol/Paracetamol contains a combination of the active substances Tramadol hydrochloride/Paracetamol, which belongs to a group of medicines used to treat pain.

Tramadol/Paracetamol is used to treat moderate to severe pain when your doctor recommends that a combination of tramadol hydrochloride and paracetamol is needed.

This medicine has been prescribed for you for tramadol/paracetamol. It contains the tramadol hydrochloride which belongs to a class of medicines called opioids, which are ‘pain relievers’. This medicine has been prescribed to you and should not be given to anyone else. Opioids can cause addiction and you may get withdrawal symptoms if you stop taking it suddenly. Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.

2. What you need to know before you take Tramadol/Paracetamol

Do not take Tramadol/Paracetamol

• if you are allergic or have had an allergic reaction (for instance skin rash, swelling of

  the face, wheezing or difficulty breathing) to tramadol, paracetamol or any of the other ingredients of this medicine (listed in section 6)

• in cases of acute alcohol poisoning
• if you are taking sleeping pills, pain relievers or medicines that affect mood and emotions

• if you are also taking medicines called monoamine oxidase inhibitors (MAOIs) or

  have taken MAOIs in the last 14 days before treatment with Tramadol/Paracetamol. MAOIs are used in the treatment of depression or Parkinson’s disease.

• if you have a severe liver disorder
• if you have epilepsy that is not adequately controlled by your current medicine.

Warnings and precautions

Talk to your doctor or pharmacist before taking Tramadol/Paracetamol

Your doctor needs to know before you take Tramadol/Paracetamol if you have or have had any of the following conditions:

• taking other medicines containing Tramadol/Paracetamol

• have liver problems or disease as your eyes and skin may turn yellow, which may

  suggest jaundice or problems with your bile ducts;

• have kidney problems
• have severe difficulties in breathing, for example asthma or severe lung problems
• have epilepsy or have already experienced fits or seizures

• have recently suffered from a head injury, shock or severe headaches associated

  with vomiting (being sick)

• are dependent on any medicine (for example morphine)
• take other medicines to treat pain that contain buprenorphine, nalbuphine or pentazocine

• are going to have an anaesthetic (tell your doctor or dentist that you are taking

  Tramadol/Paracetamol).

• are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs.

• have previously suffered from withdrawal symptoms such as agitation, anxiety,

  shaking or sweating, when you have stopped taking alcohol or drugs.

• feel you need to take more of Tramadol/Paracetamol to get the same level of pain

  relief, this may mean you are becoming tolerant to the effects of this medicine or are becoming addicted to it. Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative pain reliever.

• Suffer from depression and you are taking antidepressants as some of them may

  interact with tramadol (see ‘Other medicines and Tramadol/ Paracetamol’).

Sleep-related breathing disorders

Tramadol/Paracetamol contains an active substance that belongs to the group of opioids. Opioids can cause sleep-related breathing disorders such as central sleep apnoea (shallow/pause of breathing during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. The risk of experiencing central sleep apnea is dependent on the dose of opioids. If you or another person observe these symptoms, contact your doctor. A dose reduction may be considered by your doctor.

There is a small risk that you may experience a so-called serotonin syndrome that can occur after having taken tramadol in combination with certain antidepressants or tramadol alone. Seek medical advice immediately if you have any of the symptoms related to this serious syndrome (see section 4 ‘Possible side effects’).

Tramadol is transformed in the liver by an enzyme. Some people have a variation of this enzyme and this can affect people in different ways. In some people, they may not get enough pain relief but other people are more likely to get serious side effects. If you notice any of the following side effects, you must stop taking this medicine and seek immediate medical advice: slow or shallow breathing, confusion, sleepiness, small pupils, feeling or being sick, constipation, lack of appetite.

If any of the above-mentioned points applied to you in the past or applies to you while you are taking Tramadol /Paracetamol, please make sure your doctor knows. He/she can then decide whether you should continue to use this medicine.

Tolerance, dependence, and addiction

This medicine contains Tramadol, which is an opioid. It can cause dependence and/or addiction.

This medicine contains tramadol which is an opioid medicine. Repeated use of opioids may result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of Tramadol/Paracetamol can also lead to dependence, abuse and addiction, which may result in life-threatening overdose. The risk of these side effects can increase with a higher dose and longer duration of use.

Taking this medicine regularly, particularly for a long time, can lead to addiction. Dependence or addiction can make you feel that you are no longer in control of how much medicine you need to take or how often you need to take it. Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.

Rarely, increasing the dose of this medicine can make you more sensitive to pain. If this happens, you need to speak to your prescriber about your treatment.

The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent on or addicted to Tramadol/Paracetamol if:

• You or anyone in your family have ever abused or been dependent on alcohol,

  prescription medicines or illegal drugs (“addiction”).

• You are a smoker.

• You have ever had problems with your mood (depression, anxiety, or a personality

  disorder) or have been treated by a psychiatrist for other mental illnesses.

  Addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, loss of appetite, shaking, shivering or sweating. Your prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms.

  If you notice any of the following signs whilst taking Tramadol/Paracetamol, it could be a sign that you have become dependent or addicted:

  • You need to take the medicine for longer than advised by your doctor
  • You need to take more than the recommended dose
  • You might feel that you need to carry on taking your medicine, even when it doesn’t help to relieve your pain.
  • You are using the medicine for reasons other than prescribed, for instance, ‘to stay calm’ or ‘help you sleep’
  • You have made repeated, unsuccessful attempts to quit or control the use of the medicine
  • When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again (‘withdrawal effects’)

If you notice any of these signs, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to stop safely (See section 3, If you stop taking Tramadol/Paracetamol).

Opioids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of opioid, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.

Adolescents and Adults over 12 years

The recommended dosage is to start with 2 tablets, unless otherwise prescribed by your doctor. If required, further doses may be taken, as instructed by your doctor.

The shortest time between doses must be at least 6 hours.

Do not take more than 8 tablets per day.

Your doctor may increase the time between doses if:

• you are older than 75 years
• you have kidney problems
• you have liver problems.

Children and adolescents

Use in children with breathing problems

Tramadol is not recommended in children with breathing problems, since the symptoms of tramadol toxicity may be worse in these children.

Talk to your doctor if you experience any of the following symptoms while taking Tramadol/ Paracetamol:

Extreme fatigue, lack of appetite, severe abdominal pain, nausea, vomiting or low blood pressure. This may indicate that you have adrenal insufficiency (low cortisol levels). If you have these symptoms, contact your doctor, who will decide if you need to take hormone supplement.

Other medicines and Tramadol/Paracetamol

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

• Gabapentin or pregabalin to treat epilepsy or pain due to nerve problems (neuropathic pain)

Your doctor will tell you which medicines are safe to take with Tramadol/Paracetamol. Do not exceed the maximum daily doses of Tramadol/Paracetamol from this or other medicines.

Do not take Tramadol/Paracetamol with MAOIs (see section ‘Do not take Tramadol/ Paracetamol’).

Tramadol/Paracetamol is not recommended with the following medicines, as it may affect how well they work:

• carbamazepine (a medicine used to treat epilepsy or some types of pain)
• buprenorphine, nalbuphine or pentazocine (opioid-type pain relievers).

Please inform your doctor or pharmacist if you are taking:

• flucloxacillin (antibiotic), due to a serious risk of blood and fluid abnormality (high anion gap metabolic acidosis which occurs when there is an increase in blood plasma acidity) that must have urgent treatment and which may occur particularly in case of severe kidney or liver impairment, sepsis (when bacteria and their toxins circulate in the blood leading to organ damage), malnutrition, chronic alcoholism, and if the maximum daily doses of paracetamol are used, especially if you take the maximum daily dose of paracetamol for longer time. High anion gap metabolic acidosis is a serious disease that must have urgent treatment.

Tramadol/Paracetamol may increase the risk of side effects if you also take the following medicines:

• triptans (used for migraine) or selective serotonin re-uptake inhibitors (SSRIs, used for depression). Check with your doctor if you experience confusion, restlessness, fever, sweating, uncoordinated movement of limbs or eyes, uncontrollable jerking of muscles or diarrhoea.

• tranquilizers, sleeping pills, other pain relievers such as morphine and codeine (also as cough medicine), baclofen (a muscle relaxant), medicines used to lower blood pressure, antidepressants or medicines to treat allergies. Check with your doctor if you feel drowsy or feel faint.

  Concomitant use of Tramadol/Paracetamol and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible. However if your doctor prescribes Tramadol/Paracetamol together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor. Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.

• if you are taking medicines which may cause convulsions (fits), such as certain antidepressants or antipsychotics. The risk of having a fit may increase. Your doctor will tell you whether Tramadol/Paracetamol is suitable for you.
• warfarin or phenprocoumon (for blood thinning). The effectiveness of such medicines may be altered and bleeding may occur (see section 4).
• if you are taking certain antidepressants, Tramadol/Paracetamol may interact with these medicines and you may experience serotonin syndrome (see section 4 ‘Possible side effects’).

• Gabapentin or pregabalin to treat epilepsy or pain due to nerve problems

  (neuropathic pain).

The effectiveness of Tramadol/Paracetamol may be altered if you also take the following medicines:

• metoclopramide, domperidone or ondansetron (medicines used to treat nausea and vomiting/being sick)
• cholestyramine (medicine used to reduce cholesterol in the blood)
