Patient leaflet - Marol 100 mg prolonged-release tablets
1. What Marol Tablets are and what they are used for
The name of your medicine is Marol 100 mg, 150 mg or 200 mg Prolonged-release Tablets. It is referred to as ‘Marol Tablets’ in the rest of this leaflet.
This medicine has been prescribed for you for the treatment of moderate to severe pain. It contains 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 Marol Tablets
Do not take Marol Tablets:
If you are allergic to tramadol hydrochloride or any of the other
ingredients of this medicine (listed in section 6).
In acute poisoning with alcohol, sleeping pills, pain relievers, or
other psychotropic medicines (medicines that affect mood and emotions).
If you are also taking MAO-inhibitors (certain medicines used for
treatment of depression) or have taken them in the last 14 days before treatment with Marol Tablets (see “Other medicines and Marol Tablets”).
If you are epileptic and your fits are not adequately controlled by
treatment.
- As a substitute in drug withdrawal.
Warnings and precautions:
Talk to your doctor or pharmacist before taking Marol Tablets if:
You are or have ever been addicted to opioids, alcohol, prescription
medicines, or illegal drugs
You have previously suffered from withdrawal symptoms such as
agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs
You feel you need to take more Marol Tablets 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
You suffer from depression and you are taking antidepressants as
some of them may interact with tramadol (see ‘Other medicines and Marol Tablets’)
You suffer from consciousness disorders (if you feel that you are
going to faint)
- You are in a state of shock (cold sweat may be a sign of this)
You suffer from increased pressure in the brain (possibly after a
head injury or brain disease)
- You suffer from a liver or kidney disease
- You have difficulty in breathing
You have a tendency towards epilepsy or fits because the risk of a
fit may increase.
Do not use Marol Tablets for acute post-operative pain because of the increased risk of dependency and developing serious breathing problems.
If you are going to have an operation, or have just had an operation, please tell the doctor at the hospital if you are taking Marol Tablets. Your doctor may adjust your dose.
Taking this medicine regularly, particularly for a long time, can lead to addiction. 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.
Tolerance, dependence, and addiction
This medicine contains tramadol which is an opioid medicine. Repeated use of opioids can result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of Marol Tablets 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.
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.
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 Marol Tablets 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.
If you notice any of the following signs whilst taking Marol Tablets, 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 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 Marol Tablets).
Sleep-related breathing disorders
Marol Tablets contains an active substance that belongs to the group of opioids. Opioids can cause sleep-related breathing disorders such as sleep apnoea (shallow/pause of breathing during sleep) and sleep related hypoxemia (low oxygen level in the blood). The risk of experiencing central sleep apnoea is dependent on the dose of opioids. Your doctor may consider decreasing your total opioid dosage if you experience central sleep apnoea.
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’).
Epileptic fits have been reported in patients taking tramadol at the recommended dose level. The risk may be increased when doses of tramadol exceed the recommended upper daily dose limit (400 mg). 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.
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 Marol Tablets:
Tell your doctor or pharmacist if you are taking, or have recently taken, any other medicines. Marol Tablets should not be taken together with MAO inhibitors (certain medicines for the treatment of depression). The pain-relieving effect of Marol Tablets may be reduced and the length of time it acts may be shortened, if you take medicines which contain carbamazepine (for epileptic fits) or ondansetron (prevents nausea).
Your doctor will tell you whether you should take Marol Tablets and what dose. The risk of side effects increases:
- if you are taking other pain relievers such as morphine and codeine (also as cough medicine), and alcohol while you are taking Marol Tablets. You may feel drowsier or feel that you might faint. If this happens tell your doctor.
- Concomitant use of Marol Tablets and tranquillizers,sleeping pills (e.g. benzodiazepines), or other sedatives or medicines that impair breathing activity (e.g. opioids) or Gabapentin or pregabalin to treat epilepsy or pain due to nerve problems (neuropathicpain) 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 Marol Tablets together with sedating medicines the dose and the duration of concomitant treatment should be limited by your doctor. Please tell your doctor about all sedating 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 if you take Marol Tablets at the same time. Your doctor will tell you whether Marol Tablets are suitable for you.
- if you take coumarin anticoagulants (medicines for blood thinning), such as warfarin, together with Marol Tablets. The effect of these medicines on blood clotting may be affected and bleeding may occur.
- if you are taking certain antidepressants, Marol Tablets may interact with these medicines and you may experience serotonin syndrome (see section 4 ‘Possible side effects’) medicines used to treat allergies, travel sickness or nausea (antihistamines or antiemetics)medicines to treat psychiatric disorders (antipsychotics or neuroleptics)
- muscle relaxants
- medicines to treat Parkinson’s disease.
Taking Marol Tablets with food, drink and alcohol
Do not drink alcohol during treatment with Marol Tablets as its effect may be intensified. Food does not influence the effect of Marol Tablets. 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.
Pregnancy, breast-feeding and fertility
Do not take Marol Tablets if you are pregnant or think you might be pregnant unless you have discussed this with your prescriber and the benefits of treatment are considered to outweigh the potential harm to the baby.
If you use Marol Tablets during pregnancy, your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.
Do not take Marol Tablets while you are breastfeeding as tramadol passes into breast milk and will affect your baby.
Based on human experience tramadol is suggested not to influence female or male fertility.
