WHAT FENYLAT IS AND WHAT IT IS USED FOR

Fenylat is a strong painkiller; its painkilling activity is mediated through the central nervous system.

Adults:

Fenylat is used for long-term management of severe and long-lasting pain that can only be managed adequately with strong pain relievers (opioid analgesics).

Children:

Fenylat is used for long-term management of severe chronic pain that can only be managed adequately with strong pain relievers (opioid analgesics) in children aged 2 years or older who have previously been treated with opioid analgesics.

Do not use Fenylat:

•    if you are hypersensitive (allergic) to fentanyl, peanut, soya or any of the other ingredients of this medicine (listed in section 6).

•    if you suffer from pain which lasts only for a short period, e. g. after a surgical procedure.

•    if your central nervous system is severely impaired, for instance by brain injury.

•    if your breathing function is severely impaired. Warnings and precautions

Talk to your doctor before using Fenylat.

Warning:

Fenylat is a medicinal product that could be life-threatening to children.

This is also the case with used transdermal patches.

Bear in mind that the design of this medicinal product could be tempting to a child.

Fenylat can have life-threatening side-effects in persons that are not using prescribed opioid medicines on a regular basis.

This medicine should only be used under the supervision of a doctor who is experienced in the treatment of pain.

Your doctor will use the treatment with Fenylat as a part of an integrated management of pain and will assess you for your individual response to Fenylat at regular intervals.

As strong pain relievers may cause breathing problems, Fenylat should be used with caution, under special supervision and at low doses in patients with

•    existing breathing problems (respiratory depression), asthma. Breathing difficulties may continue or re-occur following removal of the transdermal patch, therefore, you must be monitored for these signs. The probability of these side-effects increases with increasing doses and may be increased by medicines affecting brain function (see section "Using other medicines")

•    diseases of the lungs, e.g. chronic pulmonary disease (CPD), as breathing may be reduced

•    impaired liver and/or kidney function as excretion of fentanyl may be delayed.

Particular care is necessary

•    if you have severe side-effects. Following removal of Fenylat you should be monitored for at least 24 hours or longer, depending on your symptoms.

•    if you have had a head injury, a brain tumour, signs of increased intracranial pressure, changes in your state of consciousness or loss of consciousness or coma. Strong pain relievers (opioids) may mask the course of head injury.

•    if you have a too slow, irregular heartbeat (bradyarrhythmia)

•    if you have low blood pressure or lack of fluid (hypovolaemia). This should be treated prior to initiation of treatment with Fenylat.

•    if you are at an advanced age.

•    if you suffer from long-lasting constipation.

•    if you have existing or suspected loss of muscle function of the bowel: treatment with Fenylat must be stopped.

•    if you suffer from myasthenia gravis (a disease causing tiredness and weakness of the muscles).

•    if you are addicted to medicines or alcohol or have a history of drug abuse.

Repeated use of strong pain relievers (opioids) may lead to physical or psychological dependence. Plowever, this is rarely seen when opioids are prescribed by a doctor (see section "Possible side effects").

Do not cut Fenylat patches. The patches should be controlled before use. A divided, cut or in any way damaged patch should not be used.

Fenylat patches should only be used on the skin of the person that it is prescribed for. In a few cases the patch has stuck to another person after close physical contact, e.g. when sharing a bed. A patch attached to another person (especially a child) who normally does not use fentanyl patches, may lead to overdose. In this case, you should immediately remove the patch and inform a doctor.

Fever/external heat application

Information is available that the blood concentration of fentanyl may possibly increase by one third, when the skin temperature rises to 40°C. Inform your doctor if you develop a fever during the treatment.

For this reason you should avoid exposing the patch on the skin to direct heat such as heating pads, electric blankets, heated water beds, heat or tanning lamps, intensive sun bathing, hot water bottles, saunas, prolonged hot baths, or hot whirlpool spa baths.

Children and adolescents

Fenylat should not be administered to children, who have not been treated with opioids before. Patients may experience with a significant or life-threating respiratory depression.

Fentanyl transdermal patch has not been studied in children under 2 years of age. Fenylat should be administered only to opioid-tolerant children age 2 years or older (please see "Flow to use Fenylat"). Fenylat should not be used in children under 2 years of age.

To minimise the potential of young children removing and consuming the patch, the site of administration should be chosen carefully. The adhesion of the patch should be monitored carefully and if necessary the patch should be reapplied. The patch should be applied, removed and disposed of by a clinical person, a doctor or by an adult attending the child and not by the child. Fenylat should be stored out of the sight and reach of children before and after administration.

Misuse for doping (cheating at competitive events)

The use of Fenylat can lead to positive results in doping tests. Using Fenylat for doping reasons can result in a risk to your health.

Other medicines and Fenylat

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.This includes medicines that you buy without a prescription.

If you take any of the following medicines, an interactive increase of the central depression is to be expected and side effects like difficulty in breathing, low blood pressure, severe sleepiness/coma and death are possible:

•    strong painkillers

•    depressants and hypnotics

•    medicines used to put you to sleep or for relaxation of your muscles (in the case of a planned medical or dental procedures with anaesthesia/narcosis, please inform your doctor or dentist that you are using Fenylat.

•    phenothiazines (medicines to treat neuroleptic disease)

•    medicines used for treating anxiety

•    medicines used for treating allergies (antihistamines that make you feel tired)

•    alcohol

The concomitant use with specific medicine (CYP3A4 inhibitors) may reduce the breakdown of fentanyl in the liver which could increase or prolong the therapeutic effects and side effects, e.g.:

•    ritonavir, nefinavir (medicines to treat viruses)

•    ketoconazole, itraconazole, fluconazole, voriconazole (medicines to treat fungal diseases)

•    troleandomycine, clarithromycine (antibiotics)

•    nefazodone (medicine to treat depressions)

•    verapamile, diltiazem (medicines to treat heart diseases and high blood pressure)

•    amiodarone (medicine to treat a heart problem called arrhythmia)

Concomitant use of specific medicines (CYP3A4 inducers) may increase breakdown of fentanyl in the liver, which could decrease the therapeutic effects, e.g.

•    rifampicin (antibiotic)

•    carbamazepine, phenobarbital, phenytoin (for treatment of epilepsy)

Once you stop these medicines (CYP3A4 inducers) it may increase or prolong the therapeutic effects and side-effects of fentanyl which can affect your breathing. In this situation you will require special monitoring and your dose will be adjusted.

You should not use Fenylat if you are taking Monoamine Oxidase Inhibitors (MAOI) (for treatment of depression or Parkinson's disease) or have taken them within the last 14 days.

Please tell your doctor if you are taking special medicines against depression, known as Serotonin Re-uptake Inhibitor (SSRI), or Serotonin Norepinephrine Re-uptake Inhibitor (SNRI) or a Monoamine Oxidase Inhibitor (MAOI). Your doctor should know any treatment with these medicines as the concomitant use with Fenylat may increase the risk for the potentially life-threatening serotonin syndrome.

If you are using Fenylat you should not take other pain killers like buprenorphine, nalbuphine or pentazocine because they could counteract the effects of fentanyl (e.g. analgesic effect) and may cause withdrawal symptoms in people who are dependent on opioids.

Fenylat with food, drink and alcohol

Patients, treated with Fenylat should not drink alcohol. Pregnancy and breast-feeding

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.

Pregnancy

There are no adequate data from the use of fentanyl, the active ingredient of Fenylat in pregnant women. Therefore you should not use Fenylat during pregnancy unless your doctor decides it is necessary. There is a risk of neonatal withdrawal syndrome in newborn infants where the mother has used transdermal fentanyl a lot during pregnancy.

Use of Fenylat during childbirth is not recommended because fentanyl passes through the placenta and may cause breathing problems in the newborn child.

Breast-feeding

Fentanyl passes into the breast-milk. Therefore breastfeeding should be stopped during treatment with Fenylat and for at least 72 hours after the removal of the patch.

Driving and using machines

Fenylat can affect your ability to drive and use machines as it may make you feel sleepy or dizzy.

In patients on a stable fentanyl dose, a significant impairment of the ability to drive and use machines is not expected. Plowever at the beginning of treatment, upon increase of dose or upon combination with other medicinal products, some people's reactions may be affected, leading to impairment of the ability to drive or use machines. Such situations should be handled with caution.

During treatment with Fenylat do not drive or use machines, nor do so for at least 24 hours after the end of treatment.

•    It is an offence to drive if this medicine affects your ability to drive.

•    Plowever, you would not be committing an offence if:

•    Fenylat 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.

Fenylat contains soya oil

If you are allergic to peanut or soya, do not use this medicinal product.

HOW TO USE FENYLAT

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

The recommended dose is:

Adults

Determining the treatment amount (dosage adjustment)

Your doctor will decide which strength of Fenylat is the most appropriate for you. Your doctor will make the decision based upon:

•    the intensity of your pain

•    your general conditions

•    your previous analgesic therapy

If you have not previously received strong analgesics, treatment should be initiated with the lowest concentration of the active substance.

Since the concentration of fentanyl in the bloodstream rises slowly, the current analgesic treatment should be reduced slowly until the desired analgesic effect is obtained. Fundamentally, the maximum analgesic effect can only be assessed after approximately 24 hours.

Therefore, when switching from other strongly acting analgesics to Fenylat, the 24 hour requirement of the previously administered strong analgesic should first be calculated by your doctor.

Special populations

Elderly patients and those with hepatic or renal impairment should be observed carefully and the dose reduced if necessary.

Children aged 2 to 1 6 years old

Fenylat should only be prescribed to children aged 2 to 16, who have been already treated with at least 30 mg oral morphine doses per day or with any equivalent analgesic (morphine equivalent).

Your doctor will calculate the dosage of Fenylat as follows:

•    For children who received 30 mg to 44 mg oral morphine equivalent per day the therapy should start with one Fenylat 1 2 pg/h transdermal patch.

•    For children who received 45 mg to 134 mg oral morphine equivalent per day the therapy should start with two Fenylat 12 pg/h transdermal patches.

For children who received more than 90 mg oral morphine equivalent a day, only limited information is currently available with Fenylat 100 pg/h. If the analgesic effect of Fenylat 100 pg/h is insufficient, supplementary morphine or another short-duration opioid should be administered. Depending on the additional analgesic needs and the pain status of the child, your doctor may decide to increase the dose. Dose adjustments should be done in 12 pg/h (micrograms per hour) steps.

Adolescent aged 16 years and above

Adolescent aged 16 years and above please follow adult

dosage.

Dosage for maintaining the effect

If the analgesic effect is still insufficient after 72 hours, the dose may be increased step by step until the desired analgesic effect is obtained. The required dose adjustments will be decided by your doctor. The possible need for other analgesics and the patient's sensation of pain should be taken into account.

Use of several patches simultaneously

If the required dose exceeds 100 microgram fentanyl per hour, several patches of differing strength may be used simultaneously.

Additional or alternative methods of analgesic treatment should be considered if the required dose exceeds 300 microgram fentanyl per hour.

Change of treatment

If there is intent to switch from Fenylat to another strongly acting analgesic, the patch is removed, and the dosage of the new analgesic is adapted using the patient's pain assessment.

After switching or reducing the dose, some patients may experience opioid withdrawal symptoms. If stoppage of Fenylat is necessary, step-by-step reduction of the dose is recommended.

How and when to use Fenylat

Immediately after the transdermal patch has been removed from the package and the release film as well as both sections of the backing film have been detached, the transdermal patch is attached to a hairless part of the skin or if this is not possible, hair at the application site should be clipped (not shaved) prior to application to the upper body (chest, back, upper arm).

In young children, the upper back is the preferred location to apply the patch, to minimise the potential of the child removing the patch.

The skin should be cleaned carefully with clean water and thoroughly dried before the transdermal patch is attached (no cleaning agents should be used!). The transdermal patch is then adhered to the skin with the flat hand with a light pressure for 30 to 60 seconds. It must be ensured that the application area does not show any microlesions (e.g. due to radiation or shaving) or irritation.

As the outside of the transdermal patch is protected by a waterproof foil, the transdermal patch needs not be removed to take a shower.

No creams, oils, lotions or powders should be applied to the application area as they may impair the effective adhesion of the transdermal patch to the skin.

Only open the pouch immediately before use of the patch.

Advice for opening child resistant sachet:

1)    You'll find a mark which shows you how to cut the sachet (using scissors!)

2)    Rip the sachet alongside using the resulting cuts

3)    Open the sachet and take out the patch

After sticking half of the patch onto the skin, you can remove the other half of the pull-off foil.

Firmly press the patch onto the skin with your flat hand for 30 - 60 seconds. Ensure that the adhesive edges stick well.

After applying the patch, wash your hands without using cleaning agents.

A patch that has been divided, cut or damaged in any way should not be used. Always use this medicine exactly as your doctor has told you. Check with your doctor if you modify the treatment or discontinue.

How long to use Fenylat

You should change your patch after 72 hours (3 days). If required in individual cases, do not change the patch sooner than every 48 hours, since an increased risk of side effects (primarily respiratory suppression) must otherwise be expected.

You must use a different skin area each time. Each used skin area can only be used again after at least 7 days. The analgesic effect may persist for some time after the transdermal patch has been removed.

If residue is found on the skin after the patch has been removed, remove it with soap and water. Do not use alcohol or other solvents, as these may penetrate the skin.

Please speak to your physician if you have the impression that the effect of Fenylat is too strong or weak for you.

If you use more Fenylat than you should

If you have stuck on more patches than prescribed, remove the patches and contact your doctor or hospital on their opinion of the risk.

The most common sign of overdose is the reduced ability to breathe. Symptoms are that the person breathes too slowly or too weakly. If this should occur - remove the patch and contact a doctor immediately. While waiting for the doctor, keep the person awake by talking to or shaking them now and then.

Other signs and symptoms of overdose are:

•    drowsiness

•    low body temperature

•    slow heart rate

•    decreased muscle tone

•    deep sedation

•    loss of muscle co-ordination

•    constriction of the pupils

•    convulsions

If you forget to use Fenylat

Do not under any circumstances use a double dose to make up a forgotten dose.

You should change your patch at the same time of day every three days (every 72 hours), unless directed otherwise by your doctor. If you forget, then change your patch as soon as you remember. If you are very late changing your patch then you should contact your doctor because you might need some extra painkillers.

If you stop using Fenylat

If you wish to interrupt or stop the treatment, you should always talk to your doctor.

Prolonged use of Fenylat can cause physical dependence. If you stop using the patches you may feel unwell.

As the risk of withdrawal symptoms is greater when the treatment is stopped suddenly, you should never stop treatment with Fenylat independently but always consult your doctor first.

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

Like all medicines, this medicine can cause side effects, although not everybody gets them.

The most serious undesirable effect of fentanyl is respiratory depression.

If this should occur - remove the patch and contact a doctor immediately. While waiting for the doctor, keep the person awake by talking to or shaking her/him now and then.
