Q What Zydol SR is and what it is used for
Tramadol - the active substance in Zydol SR - is a painkiller belonging to the class of opioids that acts on the central nervous system. It relieves pain by acting on specific nerve cells of the spinal cord and brain.
Zydol SR is used for the treatment of moderate to severe pain.
0 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 think that you are addicted to other pain relievers (opioids);
- if you suffer from consciousness disorders (if you feel that you are going to faint);
- if you are in a state of shock (cold sweat may be a sign of this);
- if you suffer from increased pressure in the brain (possibly after a head injury or brain disease);
- if you have difficulty in breathing;
- if you have a tendency towards epilepsy or fits because the risk of a fit may increase;
- if you suffer from a liver or kidney disease.
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).
Please note that Zydol SR may lead to physical and psychological addiction.
When Zydol SR is taken for a long time, its effect may decrease, so that higher doses have to be taken (tolerance development). In patients with a tendency to abuse medicines or who are dependent on medicines, treatment with Zydol SR should only be carried out for short periods and under strict medical supervision.
Please also inform your doctor if one of these problems occurs during Zydol SR treatment or if they applied to you in the past.
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);
- pentazocine, nalbuphine or buprenorphine (pain killers);
- ondansetron (prevents nausea).
Your doctor will tell you whether you should take Zydol SR, and what dose. The risk of side effects increases,
- if you take tranquillizers, sleeping pills, 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.
- 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 symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38C.
- if you take 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.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
There is very little information regarding the safety of tramadol in human pregnancy. Therefore you should not use Zydol SR if you are pregnant. Chronic use during pregnancy may lead to withdrawal symptoms in newborns.
Generally, the use of tramadol is not recommended during breast-feeding. Small amounts of tramadol are excreted into breast milk. On a single dose it is usually not necessary to interrupt breast-feeding. Please ask your doctor for advice.
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, and do not work without a firm hold!
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.
