Contents of the pack and other information
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 procedure with anaesthesia/narcosis, please inform your doctor or
dentist that you are using Fencino®
- phenothiazines (medicines to treat neuroleptic disease)
- medicines used for treating anxiety
- medicines used for treating allergies (antihistamines that make you feel tired)
The concomitant use with specific medicines (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)
- troleandomycin, clarithromycin (antibiotics)
- nefazodone (medicine to treat depression)
- verapamil, diltiazem (medicines to treat heart diseases and high blood pressure)
- amiodarone (medicine to treat a heart problem called arrhythmia)
1. WHAT FENCINO® IS AND WHAT IT IS USED FOR
Fencino is a strong painkiller; its painkilling activity is mediated through the central nervous system.
Fencino® is used for long-term management of severe and long-lasting pain that can only be
managed adequately with strong pain relievers (opioid analgesics).
Fencino® 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.
2. WHAT YOU NEED TO KNOW BEFORE YOU USE FENCINO
Do not use Fencino®:
- 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 Fencino®.
Fencino® 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, which in some cases may lead to a fatal outcome.
Fencino® 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 Fencino® as a part of an integrated
management of pain and will assess you for your individual response to Fencino® at regular
As strong pain relievers may cause breathing problems, Fencino® 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
- 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.
Use of fentanyl transdermal patch in patients without treatment of opioids (strong pain relievers)
before has been associated with very rare cases of significant respiratory depression and/or
fatality when used as initial opioid therapy. It is recommended that fentanyl transdermal patch be
used only in patients who have demonstrated opioid tolerance and should be initiated with the
lowest dose of fentanyl transdermal patch.
Particular care is necessary
- if you have severe side effects. Following removal of Fencino® you should be monitored for at
least 24 hours or more, as clinical symptoms dictate.
- 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 Fencino®.
- 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
Fencino® must be stopped.
- if you suffer from myasthenia gravis (a disease causing tiredness and weakness of the
- 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. However, this is rarely seen when opioids are prescribed by a doctor (see
section “Possible side effects”).
Do not cut Fencino® patches. The patches should be controlled before use. A divided, cut or in
any way damaged patch should not be used.
Patch sticking to another person
Fencino® patches should only be used on the skin of the person for whom it was ordered by the
doctor. Cases have been reported where a patch was accidentally stuck to a family member
while in close physical contact or sharing the same bed as the patch wearer. A patch sticking to
another person (particularly a child) may result in an overdose. If the patch sticks to the skin of
another person, take the patch off immediately and seek medical attention.
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
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
Fencino® should not be administered to children who have not been treated with opioids before.
Patients may experience a significant or life-threatening respiratory depression.
Fentanyl transdermal patch has not been studied in children under 2 years of age. Fencino®
should be administered only to opioid-tolerant children age 2 years or older (please see “How to
use Fencino®”). Fencino® should not be used in children under 2 years of age.
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 careful
monitoring and dose adjustment should be made if warranted.
You should not use Fencino® 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 Fencino® may increase the risk for the potentially
life-threatening serotonin syndrome.
If you are using Fencino® 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.
Fencino® with food, drink and alcohol
Patients, treated with Fencino® 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.
There are no adequate data from the use of fentanyl, the active ingredient of Fencino®, in
pregnant women. Therefore you should not use Fencino® 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 Fencino® during childbirth is not recommended because fentanyl passes through the
placenta and may cause breathing problems in the newborn child.
Fentanyl passes into the breast milk. Therefore breast-feeding should be stopped during
treatment with Fencino® and for at least 72 hours after the removal of the patch.
Driving and using machines
Fencino® can influence the ability to drive and use machines.
In patients on a stable fentanyl dose, a significant impairment of the ability to drive and use
machines is not expected. However 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
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
Fencino® contains soya oil
If you are allergic to peanut or soya, do not use this medicinal product.
3. HOW TO USE FENCINO®
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:
Determining the treatment amount (dosage adjustment)
Your doctor will decide which strength of Fencino® 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 Fencino®, the 24 hour
requirement of the previously administered strong analgesic should first be calculated by your
Elderly patients and those with hepatic or renal impairment should be observed carefully and
the dose reduced if necessary.
Children aged 2 to 16 years old
Fencino® 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
Your doctor will calculate the dosage of Fencino® as follows:
- For children who received 30 mg to 44 mg oral morphine equivalent per day the therapy
should start with one Fencino® 12 µg/h transdermal patch.
- For children who received 45 mg to 134 mg oral morphine equivalent per day the therapy
should start with two Fencino® 12 µg/h transdermal patches.
For children who received more than 90 mg oral morphine equivalent per day, only limited
information is currently available with Fencino® 100 µg/h. If the analgesic effect of Fencino®
100 µg/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 µg/h
(micrograms per hour) steps.
Adolescents aged 16 years and above
Adolescents 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.
Very common: may affect more than 1 in 10 people
- sleepiness, dizziness, headache
- nausea, vomiting, constipation
Additional or alternative methods of analgesic treatment should be considered if the required
dose exceeds 300 microgram fentanyl per hour.
Common: may affect up to 1 in 10 people
- hypersensitivity of the immune system
- loss of appetite
- not able to sleep, depression, anxiety, feeling confused, hallucinations
- tremor, pins and needles
- conjunctivitis (an eye infection)
- vertigo (feeling sick and dizzy)
- palpitations and an increase in heart rate
- increase in blood pressure
- shortness of breath
- diarrhoea, dry mouth, stomach pain, indigestion
- increased sweating, itching, rash, skin reddening
- muscle spasms
- difficulty passing urine
- tiredness, swelling, particularly in feet ankles and hands (peripheral oedema), rapid
tiredness (asthenia), a feeling of discomfort and uneasiness (malaise), feeling cold
Change of treatment
If there is intent to switch from Fencino® 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 Fencino® is necessary, step-by-step reduction of the dose is recommended.
How and when to use Fencino®
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
Then remove the pull-off foil from half of the patch. It is important to
avoid touching the adhesive surface.
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.
To minimise the potential of young children removing and consuming the
patch, the patch should be stuck on the back. The adhesion of the patch
should be monitored carefully and if necessary the patch should be
After applying the patch, wash your hands without using cleaning agents.
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 Fencino®
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 doctor if you have the impression that the effect of Fencino is too strong
or weak for you.
Using and changing the patches
There is enough medicine in each patch to last 3 days (72 hours)
You should change your patch every third day, unless your doctor has told you otherwise.
Always remove the old patch before applying the new one.
Always change your patch at the same time of day every 3 days (72 hours)
Make a note of the day, date and time you apply a patch, to remind you when you need to
change your patch.
The following table shows you which day of the week to change your patch.
Apply your patch on day
Change your patch at the same time on
If you use more Fencino® than you should
If you have stuck on more patches than prescribed, remove the patches and contact your
doctor or hospital for 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:
low body temperature
slow heart rate
decreased muscle tone
loss of muscle co-ordination
constriction of the pupils
If you forget to use Fencino®
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 Fencino®
If you wish to interrupt or stop the treatment, you should always talk to your doctor.
Prolonged use of Fencino® 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 Fencino® independently but always consult your doctor first.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
4. POSSIBLE SIDE EFFECTS
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.
The following side effects are based on clinical trials with adults and children as well as
experience of adults using this product after registration:
If any of the following side effects occur you should discontinue treatment and immediately
contact your doctor or visit a hospital.
