What Invodol SR is and what it is used for


Tramadol hydrochloride, the active substance in Invodol SR, is a centrally active analgesic of the opioid group. Its pain alleviating effects are attributable to its influence on specific nerve cells in the spinal cord and in the brain.

Invodol SR is used:

• in the treatment of moderately severe to severe pain.


2 Before you take Invodol SR


Do not take Invodol SR

•    if you are allergic (hypersensitive) to tramadol hydrochloride or any of the other ingredients of Invodol SR

•    if you have acute intoxication with alcohol, sleeping agents, centrally acting painkillers, opioids or other psychotropic agents (medicines which influence mood, emotional status and disposition)

•    if you are taking MAO inhibitors concomitantly (specific medicines which are used to treat abnormally depressive mood [depression] or Parkinson's disease) or have taken these in the last 14 days prior to starting treatment with Invodol SR (see “Taking other medicines”)

•    if you have epilepsy and this cannot be adequately controlled by use of medicines

•    asa substitute in drug withdrawal treatment.

Take special care with Invodol SR if you

•    think you may already be dependent on other analgesic agents (opioids)

•    have a consciousness disturbance (e.g. if you feel unusually dazed)

•    are in shock (cold sweat can be an indication of this)

•    have difficulty in breathing

•    have a condition which involves increased cerebral pressure (possible after head injuries or in the presence of brain disorders)

•    have a liver or kidney disorder

•    react sensitively to opiates

•    tend to be epileptic or suffer seizures.

If any of the above applies to you, please talk to your doctor before starting to take this medicine.

Epileptic fits have been reported in patients taking tramadol at the recommended dose level. The risk may be increased if the recommended maximum daily dose of 400 mg tramadol is exceeded or if you are taking medicines concomitantly which lower the seizure threshold (see “Taking other medicines”).

Please note that psychological and physical dependence can develop in patients on Invodol SR.

During long-term use, the effects of Invodol SR may weaken, with the result that it becomes necessary to use a higher dose (development of tolerance). For this reason, Invodol SR must be used for short periods only and under strictest medical supervision in patients at risk of developing drug dependence.

Please also inform your doctor if any of these problems develop while you are taking Invodol SR and ifyou have experienced such problems in the past.

Children

Invodol SR is not suited for use in children of less than 12 years of age (see section 3 “How to take Invodol SR”).

The elderly

Patients of more than 75 years of age should be monitored carefully as the elimination of tramadol can be prolonged (see section 3 “How to take Invodol SR”).

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

The analgesic effects of Invodol SR may be reduced and the duration of therapeutic effects may be shortened if you are taking medicines containing one of the following active substances:

   carbamazepine (used to treat epileptic seizures)

•    pentazocine, nalbuphine or buprenorphine

(painkillers)

   ondansetron (used to treat nausea).

The risk of side effects increases

•    if you take Invodol SR concurrently with other medicines which also depress brain function, e.g. cough medicines, some analgesics, sleeping agents, preparations used to treat anxiety states and preparations used as substitutes during drug withdrawal treatment. In these cases, there is an increased risk of depression of respiratory activity or, in extreme circumstances, there can be respiratory arrest in case of overdose


•    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 Invodol SR at the same time. Your doctor will tell you whether Invodol SR is suitable for you.

•    If you are taking certain antidepressants Invodol 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 38°C

•    if you are taking cimetidine (for gastric ulcers)

•    if you are concurrently taking medicines that prevent normal blood coagulation (so-called coumarin derivatives, such as warfarin). The anticoagulatory effects of these medicines can be enhanced and there can be major bleeding and haemorrhaging under small areas of the skin (ecchymosis).

Other possible interactions

Do not take Invodol SR concurrently with MAO inhibitors (medicines which are used to treat abnormally depressive mood [depression] or Parkinson's disease) or if you have taken these in the last 14days prior to starting treatment with Invodol SR. It cannot be excluded that life-threatening interactions, involving effects on the central nervous system and on respiratory and cardiovascular function, could occur.

Taking Invodol SR with food and drink

Do not drink alcohol while taking Invodol SR, this could enhance the effects of the medicine.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine.

Pregnancy

There is very little information regarding the safety of tramadol in human pregnancy. In general, you should not take Invodol SR if you are pregnant.

Repeated use of Invodol SR during pregnancy can lead to a dependency of the unborn child on the drug and, consequently, to withdrawal symptoms in the newborn child after birth.

Breast-feeding

Very small quantities of tramadol are excreted into breast milk. You should not take Invodol SR if you are breast-feeding.

As a rule, it is not necessary to interrupt breast-feeding after taking a single dose of tramadol. Please ask your doctor for advice.

Driving and using machines

Invodol SR can, among other things, cause

•    drowsiness and dizziness

•    visual disturbance (blurred vision)

and thus can impair your ability to react. Do not drive or use any tools or machines if this occurs or if you have the feeling that your ability to react is reduced.

3 How to take Invodol SR


Always take Invodol SR exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

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

The usual dose, unless otherwise prescribed by your doctor, is:

Adults and adolescents over the age of12 years

The usual starting dose is 100 mg tramadol hydrochloride twice daily, taken once in the morning and once in the evening.

If pain relief is insufficient, your doctor can increase the dose to 150 mg twice daily or 200 mg twice daily.

For doses not realisable/practicable with this medicinal product, other strengths are available.

There must be a minimum interval of 8 hours between each dose.

As a general rule, you should take no more than the minimum dose you require to control your pain.

Do not take more than 400 mg tramadol hydrochloride daily unless there are specific medical reasons for this.


Children under 12years

Invodol SR is not recommended for use in children under 12years.

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 Invodol SR. If in your case the insufficiency is mild or moderate, your doctor may recommend prolonging the dosage interval

Note'.

The doses recommended above are guideline values only. Ifyou are taking the preparation for the management of chronic pain, you should always, if possible, strictly follow a planned administration schedule.

Method of administration

Swallow the prolonged-release tablets whole with sufficient liquid (e.g. one glass of water). You can take the prolonged-release tablets separately or with meals.

It is important that you do not continue to take Invodol SR for longer than absolutely necessary.

If you take more Invodol SR than you should

This will not normally have any negative consequences for you. Continue to take Invodol SR as your pain recurs as usual.

If you have taken an excessive dose of the medicine the following signs can occur: narrowed pupils, vomiting, low blood pressure, heartfailure, feeling sleepy or drowsy (with coma in extreme cases), migraine symptoms or epileptic seizures and shallow breathing with respiratory arrest in extreme cases.

If you observe any of these symptoms or if a child accidentally takes Invodol SR, immediately contact the nearest doctor or hospital for help!

If you forget to take Invodol SR

You may experience recurrence of pain. Do not take a double dose to make up for a forgotten dose, but continue to take the preparation as prescribed.

If you stop taking Invodol SR

If you interrupt or prematurely stop treatment with Invodol SR, your pain may return. If you decide you wish to stop taking this preparation because of unpleasant side effects, please consult your doctor.

There will normally be no after-effects when you stop taking Invodol SR. However, in a few cases in which patients have been taking Invodol SR for a very long period, there have been after-effects such as restlessness, anxiety states, nervousness, insomnia, tremor or gastrointestinal upset. If you experience any of these side effects when you stop taking Invodol SR, please consult your doctor.

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