1. What ZYDOL SR is and what it is used for

The full name of your medicine is ‘ZYDOL SR 100 mg, 150 mg or 200 mg prolonged-release tablets’. It is referred to as ‘ZYDOL SR’ in the rest of this leaflet.This medicine has been prescribed for you for the treatment of moderate to severe pain.

Tramadol - the active substance in ZYDOL SR 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 ZYDOL SR
Do not take ZYDOL SR,
  • if you are allergic to tramadol 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 ZYDOL SR (see "Other medicines and ZYDOL SR");
  • if you are an epileptic and your fits are not adequately controlled by treatment;
  • as a substitute in drug withdrawal.

Warnings and precautions

Talk to your doctor before taking ZYDOL SR, if:

  • 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 have difficulty in breathing;
  • you have a tendency towards epilepsy or fits because the risk of a fit may increase;
  • you suffer from depression and you are taking antidepressants as some of them may interact with tramadol (see “Other medicines and ZYDOL SR”);
  • you suffer from a liver or kidney disease;

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 ZYDOL SR 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 ZYDOL SR 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 ZYDOL SR, 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 ZYDOL SR).

Sleep-related breathing disorders

ZYDOL SR contains an active substance that belongs to the group of opioids. Opioids can cause sleep-related breathing disorders, for example central sleep apnea (shallow/pause of breathing during sleep) and sleep-related hypoxemia (low level of oxygen in the blood).

The risk of experiencing central sleep apnea is dependent on the dose of opioids. Your doctor may consider decreasing your total opioid dosage if you experience central sleep apnea.

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).

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.

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.

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.

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.

Talk to your doctor if you experience any of the following symptoms while taking ZYDOL SR:

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 ZYDOL SR

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

ZYDOL SR should not be taken together with MAO inhibitors (certain medicines for the treatment of depression).

The pain-relieving effect of ZYDOL SR may be reduced and the length of time it acts may be shortened, if you take medicines which contain

  • carbamazepine (for epileptic fits);
  • ondansetron (prevents nausea).

Your doctor will tell you whether you should take ZYDOL SR, and which 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 ZYDOL SR. You may feel drowsier or feel that you might faint. If this happens tell your doctor.
  • Concomitant use of ZYDOL SR and tranquillizers or sleeping pills (e.g. benzodiazepines) or gabapentin or pregabalin to treat epilepsy or pain due to nerve problems (neuropathic pain) increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma or 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 ZYDOL SR 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 having a fit may increase if you take ZYDOL SR at the same time. Your doctor will tell you whether ZYDOL SR is suitable for you.
  • if you are taking certain antidepressants ZYDOL SR may interact with these medicines and you may experience serotonin syndrome (see section 4 “Possible side effects”).
  • if you are taking coumarin anticoagulants (medicines for blood thinning), e.g. warfarin, together with ZYDOL SR. The effect of these medicines on blood clotting may be affected and bleeding may occur.

ZYDOL SR with food and alcohol

Do not drink alcohol during treatment with ZYDOL SR as its effect may be intensified. Food does not influence the effect of ZYDOL SR.

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 ZYDOL SR 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 ZYDOL SR during pregnancy, your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.

Do not take ZYDOL SR 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.

Driving and using machines

ZYDOL SR may cause drowsiness, dizziness and blurred vision and therefore may impair your reactions. If you feel that your reactions are affected, do not drive a car or other vehicle, do not use electric tools or operate machinery.

The medicine can affect your ability to drive as it may make you sleepy or dizzy.

  • Do not drive while taking this medicine until you know how it affects you.
  • It is an offence to drive if this medicine affects your ability to drive.
  • However, you would not be committing an offence if:
    • The medicine has been prescribed to treat a medical or dental problem and
    • You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and
    • It was not affecting your ability to drive safely

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

ZYDOL SR contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product. This is because the tablets contain lactose

3. How to take Zydol SR

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Before starting treatment and regularly during treatment, your doctor will discuss with you what you may expect from using ZYDOL SR, when and how long you need to take it, when to contact your doctor, and when you need to stop it (see also section 2).

The dosage should be adjusted to the intensity of your pain and your individual pain sensitivity. In general the lowest pain-relieving dose should be taken. Do not take more than 400 mg tramadol hydrochloride daily, except if your doctor has instructed you to do so.

Unless otherwise prescribed by your doctor, the usual dose is:

Adults and adolescents from the age of 12 years

One ZYDOL SR 100 mg prolonged-release tablet twice daily (equivalent to 200 mg tramadol hydrochloride per day), preferably in the morning and evening.

One ZYDOL SR 150 mg prolonged-release tablet twice daily (equivalent to 300 mg tramadol hydrochloride per day), preferably in the morning and evening.

One ZYDOL SR 200 mg prolonged-release tablet twice daily (equivalent to 400 mg tramadol hydrochloride per day), preferably in the morning and evening.

Your doctor may prescribe a different, more appropriate dosage strength of ZYDOL SR if necessary.

If necessary, the dose may be increased up to 150 mg or 200 mg twice daily (equivalent to 300 mg – 400 mg tramadol hydrochloride per day).

Children

ZYDOL SR is not suitable for children below the age of 12 years.

Elderly patients

In elderly patients (above 75 years) the excretion of tramadol may be delayed. If this applies to you, your doctor may recommend prolonging the dosage interval.

Severe liver or kidney disease (insufficiency)/dialysis patients

Patients with severe liver and/or kidney insufficiency should not take ZYDOL SR. If in your case the insufficiency is mild or moderate, your doctor may recommend prolonging the dosage interval.

How and when should you take ZYDOL SR?

ZYDOL SR tablets are for oral use.

Always swallow ZYDOL SR tablets whole, not divided or chewed, with sufficient liquid, preferably in the morning and evening. You may take the tablets on an empty stomach or with meals.

How long should you take ZYDOL SR?

Your prescriber should have discussed with you, how long the course of tablets will last. They will arrange a plan for stopping treatment. This will outline how to gradually reduce the dose and stop taking the medicine.

If you take more ZYDOL SR than you should

If you have taken an additional dose by mistake, this will generally have no negative effects. You should take your next dose as prescribed.

If you (or someone else) swallow a lot of ZYDOL SR tablets at the same time you should go to hospital or call a doctor straight away. Signs of an overdose include very small pupils, being sick, a fall in blood pressure, a fast heartbeat, collapse, unconsciousness, fits and breathing difficulty or shallow breathing.

If you forget to take ZYDOL SR

If you forget to take the tablets, pain is likely to return. Do not take a double dose to make up for forgotten individual doses, simply continue taking the tablets as before.

If you stop taking ZYDOL SR

Do not suddenly stop taking this medicine. If you want to stop taking this medicine, discuss this with your prescriber first. They will tell you how to do this, usually by reducing the dose gradually so that any unpleasant withdrawal effects are kept to a minimum. Withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, shaking, shivering or sweating may occur if you suddenly stop taking this medicine.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
