Feliben is an analgesic (pain-relieving medication) indicated for the relief of moderate to severe oncological pain and severe pain that does not respond to other types of analgesics.

Felibenacts throughthe skin.When thetransdermal patchis applied to the skin,theactive ingredient buprenorphinepases through the skininto the blood.

Buprenorphine is an opioid (relieves strong pain), which reduces pain by acting on the central nervous system (on specific nerve cells in the spinal cord and brain).Theeffect of the transdermal patchhas a duration ofup to threedays.Feliben is not ideal for the treatment of acute pain (short-term).

No use Feliben

• If you are allergic to buprenorphine, soy, peanuts, or any of the other components of this medication (listed in section 6).

• If you are addicted to powerful painkillers (opioids).

• If you have a disease that makes it difficult to breathe or can cause breathing difficulties.

• If you are taking monoamine oxidase inhibitors (certain medications for depression treatment) or have taken them in the last two weeks (see “Other medications and Feliben”).

• In case of myasthenia gravis (a severe muscle weakness condition).

• In case of delirium tremens (confusion and tremors after alcohol withdrawal) or occurs during a high alcohol consumption episode.

• If you are pregnant.

Feliben should not be used to treat withdrawal syndrome in drug-dependent individuals.

Warnings and precautions

Consult your doctor or pharmacist before starting to use Feliben if

• You have recently consumed a lot of alcohol;
• You have seizures or convulsions (attacks);
• You have altered consciousness (dizziness or fainting) for an unknown reason;
• You are in shock (a sign could be cold sweat);
• You have elevated intracranial pressure (for example, after a head trauma or brain disease), without the possibility of artificial respiration;
• You have difficulty breathing or are taking another medication that can make you breathe more slowly or weakly (see “Other medications and Feliben”);
• You have liver problems;
• You have a tendency to abuse medications or drugs;
• You have depression or other diseases treated with antidepressants. The use of these medications with Feliben may cause serotonin syndrome, a potentially fatal disease (see “Use of Feliben with other medications”).

Also note the following precautions:

• The fever and ambient temperature may lead to higher-than-normal buprenorphine levels in the blood. Also, ambient temperature may prevent the patch from sticking properly. Therefore, consult your doctor if you have a fever and do not expose yourself to heat sources (for example, sauna, infrared lamps, electric blankets, or hot water bags).

Tolerance, dependence, and addiction

This medication contains buprenorphine, an opioid substance. Repeated use of opioids may reduce the effectiveness of the medication (your body becomes accustomed to the medication, which is known as tolerance). Repeated use of Feliben may also cause dependence, abuse, and addiction, which may lead to a potentially fatal overdose. The risk of adverse effects may increase with a higher dose and longer duration of use.

Dependence or addiction may make you feel that you no longer have control over the amount of medication 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 be at a higher risk of becoming dependent or addicted to Feliben if:

- You or a family member has a history of alcohol, prescription medication, or illicit substance abuse (“addiction”).

- You are a smoker.

- You have had problems with your mood (depression, anxiety, or personality disorder) or have received treatment from a psychiatrist for other mental health conditions.

If you notice any of the following signs while taking Feliben, it could be a sign that you have become dependent or addicted:

- You need to take the medication for a longer period than recommended by your doctor.

- You need to take more doses than recommended.

- You may feel that you need to continue taking your medication, even if it no longer helps to relieve pain.

- You are using the medication for reasons other than those prescribed, for example, “to calm down” or “to help you sleep”.

- You have made repeated and unsuccessful attempts to stop or control your medication use.

- You do not feel well when you stop taking the medication and feel better when you start taking it again (“withdrawal symptoms”).

If you notice any of these signs, talk to your doctor to address the most suitable treatment strategy for your case, including when it is appropriate to stop taking it and how to do it safely (see section 3 “If you interrupt treatment with Feliben”).

Athletes should be aware that this medication may cause a positive reaction in doping control tests.

Sleep-related respiratory disorders

Feliben may cause sleep-related respiratory disorders such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, nocturnal awakenings due to difficulty breathing, difficulty maintaining sleep, or excessive daytime somnolence. Contact your doctor if you or someone else observes these symptoms. Your doctor may consider reducing the dose.

Children and adolescents

• Feliben should not be used in individuals under 18 years of age, as there is no experience to date in this age group.

Use of Feliben with other medications:

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Some medications may increase the side effects of Feliben and, in some cases, may cause severe reactions. Do not take any other medication while taking Feliben without first consulting your doctor, especially:

• Feliben should not be taken with monoamine oxidase inhibitors (certain medications for depression treatment) or if you have taken this type of medication in the last two weeks.

• Feliben may cause drowsiness, vomiting, dizziness, or make you breathe more slowly or weakly in some patients. These adverse effects may intensify if taken at the same time as other medications that can cause the same effects. These other medications include other powerful painkillers (opioids), some sleep medications, tranquilizers, anesthetics, antidepressants, and neuroléptics (medications for the treatment of certain psychological diseases).

• The concomitant use of Feliben and sedative medications such as benzodiazepines or related medications increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and may put your life at risk. Therefore, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor prescribes Feliben along with sedative medications, your doctor should limit the dose and duration of concomitant treatment.

Please inform your doctor about all sedative medications you are taking and follow your doctor's recommended dose closely. It may be helpful to inform friends or family members to be aware of the signs and symptoms mentioned above. Contact your doctor when you experience these symptoms.

• If Feliben is used with other medications that block the degradation of buprenorphine, the patch's action may be intensified. These medications include, for example, certain antibiotics/antifungals (e.g., containing erythromycin or ketoconazole) or HIV medications (e.g., containing ritonavir).

• If Feliben is used with other medications that increase its degradation, the patch's action may be reduced. These medications include, for example, dexamethasone, certain epilepsy treatments (e.g., containing carbamazepine or phenytoin) or antituberculosos (e.g., containing rifampicin).

• Antidepressants such as moclobemida, tranilcipromina, citalopram, escitalopram, fluoxetina, fluvoxamina, paroxetina, sertralina, duloxetina, venlafaxina, amitriptilina, doxepina, or trimipramina. These medications may interact with Feliben and you may experience symptoms such as involuntary muscle contractions, including those that control eye movement, agitation, hallucinations, coma, excessive sweating, tremors, exaggerated reflexes, increased muscle tension, body temperature above 38 °C. Contact your doctor if you experience these symptoms.

• Gabapentina or pregabalina used to treat epilepsy or pain due to nerve problems (neuropathic pain).

• Medications for depression treatment;

• Medications used to treat allergies and for nausea or vomiting during travel (antihistamines or antiemetics).

• Medications for the treatment of psychiatric disorders (antipsychotics or neuroléptics).

• Muscle relaxants

• Medications for Parkinson's disease treatment

Use of Feliben with food, drinks, and alcohol

You should avoid drinking alcohol while taking Feliben. Alcohol may increase certain effects of the transdermal patches, and you may not feel well. If you drink grapefruit juice, it may intensify the effects of Feliben.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication.

There is not enough experience with the use of Feliben to date in pregnant women. Therefore, Feliben should not be used if you are pregnant.

Buprenorphine, the active ingredient contained in the patch, inhibits milk production and passes into breast milk. Therefore, Feliben should not be used during breastfeeding.

Driving and operating machinery

Feliben may make you feel dizzy, sleepy, or have blurred or double vision and alter your reflexes in a way that you may not react quickly or adequately to sudden or unexpected situations.

This applies especially:

• At the beginning of treatment
• When changing doses
• When changing from another medication to this one
• When you are also taking other medications that act on the brain
• When you drink alcohol

If this happens to you, do not drive or operate machinery while taking Feliben.

This also applies to the end of treatment with Feliben. Do not drive or operate machinery. Do not do so for at least 24 hours after the patch has been removed.

In case of doubt, consult your doctor or pharmacist.

Feliben contains soy oil. If you are allergic to peanuts or soy, do not use this medication.

Use this medication exactly as your doctor has told you to. Consult with your doctor or pharmacist if you are unsure.

Before starting treatment and at regular intervals during treatment, your doctor will discuss with you what you can expect from the use of Feliben, when and for how long you should take it, when to contact your doctor, and when to stop taking it (see also "If you interrupt treatment with Feliben").

Follow exactly the administration instructions for this medication as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Instructions for opening the child-resistant safety package:

1. Make a cut in the marked points on each side
2. Rip both marks along the thermosellable area
3. Open the package and remove the patch

Method of administration

Before applying the patch:

• Choose a clean, smooth, and hairless area of skin on the upper part of your body, preferably under the clavicle on the chest or on the upper back. Ask for help if you cannot apply the patch yourself.
• If the chosen area has hair, cut it with scissors. Do not shave it!
• Avoid areas of skin that are red, irritated, or have any other type of marks, such as large scars.
• The area of skin you choose must be dry and clean. If necessary, wash it with cold or warm water. Do not use soap or other detergents. After a hot bath or shower, wait until your skin is completely dry and cool. Do not apply lotions, creams, or ointments to the chosen area. This could prevent the patch from sticking properly.

Applying the patch:

1.Each patch is sealed in a package. Do not open the package until the time of use of the patch.

2.Start by separating the protective film that covers the silver part.

3.Carefully remove the half of the film. Try not to touch the adhesive part of the patch.

4.Stick the patch to the area of skin you have chosen and remove the rest of the film.

5.Press the patch against your skin with the palm of your hand for 30-60 seconds. Make sure the entire patch is in contact with your skin, especially the edges.

6.Wash your hands after applying the transdermal patch. Do not use any cleaning products.

While wearing the patch:

You can wear the patch for a maximum of3days. If the patch has been applied correctly, the risk of it falling off is low. You can bathe, shower, or swim while wearing it. However, do not expose the patch to extreme heat (for example, sauna, infrared lamps, electric blankets, hot water bottle).

If the patch falls off before you need to change it, do not use the same patch again. Apply a new one immediately (see "Changing the patch").

Changing the patch:

• Remove the old transdermal patch carefully.
• Double it over with the adhesive side inwards.
• Dispose of it carefully, out of sight and reach of children.
• Stick a new patch to a suitable area of skin (as described above). At least 1 week must pass before you can apply a new patch to the same area again.

Duration of treatment:

Your doctor will tell you the duration of your treatment with Feliben. Do not stop treatment prematurely, as the pain may return and you may feel unwell (see also "Effects when treatment with Feliben is interrupted").

If you think Feliben's action is too strong or too weak, tell your doctor or pharmacist.

If you use more Feliben patches than you should::

If this happens, there may be signs of buprenorphine overdose. An overdose can intensify the adverse effects of buprenorphine, such as drowsiness, nausea, and vomiting. Your pupils may be pinpointed, and your breathing may become slow and weak. You may experience a cardiovascular collapse.

As soon as you realize you have used more Feliben patches than you should, remove the excess patches and consult your doctor or pharmacist immediately.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20.

If you forget to use Feliben:

If you forget an application, apply a new patch as soon as you remember. If you change the patch too late, the pain may return. In this case, consult your doctor.

Never apply double the number of transdermal patches to compensate for the one you forgot.

If you interrupt treatment with Feliben:

If you interrupt or stop treatment with Feliben too soon, the pain will return.

If you want to stop treatment due to unpleasant side effects, consult your doctor. Your doctor will tell you what you can do and if other medications can be administered.

Some people may experience effects after using potent analgesics for a long time and stopping them. The risk of experiencing effects after stopping Feliben is very low. However, if you feel agitated, anxious, nervous, or tremulous, if you are hyperactive, have difficulty sleeping, or experience digestive problems, consult your doctor.

If you have any other questions about using this medication, ask your doctor or pharmacist.
