What Fentanyl Orion is and what it is used for

The name of your medicine is Fentanyl Orion.

The patches relieve very severely and long-lasting pain:

  • in adults who need continuous pain treatment
  • in children over 2 years of age who are already using opioid medicines and need continuous pain treatment.

Fentanyl Orion contains a medicine called fentanyl. It belongs to a group of strong painkillers called opioids.

Fentanyl contained in Fentanyl Orion may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before using Fentanyl Orion

Do not use Fentanyl Orion:

  • if you are allergic to fentanyl, peanuts, soy, or any of the other ingredients of this medicine (listed in section 6)
  • if you suffer from pain that lasts only a short period of time, such as sudden pain or pain after a surgical procedure
  • if you have difficulty breathing with slow or shallow breathing.

Do not use this medicine if any of the above apply to you or your child. If you have any further questions, ask your doctor or pharmacist before taking Fentanyl Orion.

Warnings and cautions

Fentanyl Orion may cause life-threatening side effects in people who are not already regularly taking prescription opioid medicines. Fentanyl Orion is a drug that can be life-threatening for children. This also applies to used patches. Keep in mind that a self-adhesive patch (unused or used) can be attractive to a child and if the patch sticks to the child’s skin or if the child puts it in his mouth, it can be fatal.

Custodian locks attached to another person

The patch should only be used on the skin of the person prescribed by the doctor. There are reported cases where a patch was accidentally stuck to a family member during close physical contact or when a bed was shared with the wearer of the patch. A patch that has adhered to another person (especially a child) can cause drugs to pass through the other person’s skin and cause serious side effects such as difficulty breathing with slow and shallow breathing, which can be fatal. If the patch has adhered to another person’s skin, remove the patch immediately and consult a physician.

Take special care with Fentanyl Orion

Talk to your doctor or pharmacist before using this medicine if any of the following apply to you – your doctor may need to examine more carefully about:

  • you have ever had problems with your lungs or breathing
  • you have ever had problems with your heart, liver, kidneys or had low blood pressure
  • you have ever had a brain tumor
  • you have ever had a prolonged headache or a head injury
  • you are older – you may be more sensitive to the effects of this medicine
  • you have a disease called myasthenia gravis when the muscles become weak and tired quickly
  • you have ever abused or been addicted to alcohol, prescription drugs, or illegal drugs.

If any of the above apply to you (or you feel unsure), talk to your doctor or pharmacist before using Fentanyl Orion.

Side effects and Fentanyl Orion

  • Fentanyl Orion may make you unusually sleepy and cause you to breathe more slowly and shallowly. In very rare cases, these breathing problems can be life-threatening or even fatal, especially in people who have never used strong painkillers with opioids (such as Fentanyl Orion or morphine). If you or your partner or caregiver notice that the person wearing the patch is unusually sleepy and is breathing slowly or shallowly:
    • Remove the patch
    • Call a doctor or go to the nearest hospital immediately
    • Make sure the person is moving and talking as much as possible
  • If you get a fever while using Fentanyl Orion, tell your doctor – it may cause an increased amount of medicine to pass through your skin.
  • Fentanyl Orion may cause constipation. Consult a doctor or pharmacist for help in preventing or treating constipation.
  • Repeated, long-term treatment with the patches may make the medicine less effective (you will become “tolerant” of it) or make you addicted to it.

See section 4 for a complete list of possible side effects.

When wearing the patch, do not expose it to direct heat, such as heating pads, electric blankets, hot water bottles, heated water beds, or heat or sun lamps. You should not sunbathe, take long hot baths, bathe or take hot whirlpool baths. If you do this, you may get an increased amount of medication from the patch

Other medicines and Fentanyl Orion

Tell your doctor or nurse if you are taking, have recently taken, or might take any other medicines. This also applies to over-the-counter medicines and herbal medicines. You should also tell your pharmacist that you are taking Fentanyl Orion if you buy any medicines at the pharmacy.

Your doctor will know which medicines are safe to take with Fentanyl Orion. If you are taking any of the types of medicines listed below or if you stop taking any of these, you may need to be closely monitored as it may affect the dose of FentanylOrion you need.

Above all, tell your doctor or pharmacist if you are taking:

  • other pain-relieving drugs, such as smärtillande drugs with opioid’s (such as buprenorphine, nalbuphine, or pentazocine)
  • medicines that help you sleep (such as temazepam, zaleplon, or zolpidem)
  • medicines that make you feel calmer (sedatives such as alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and medicines for mental problems (antipsychotics such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines)
  • muscle relaxants (such as cyclobenzaprine or diazepam)
  • Some medicines are used to treat depression, called SSRIs or SNRIs (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, or venlafaxine) – see below for more information.
  • Some medicines for depression or Parkinson’s disease called MAO inhibitors(such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). You should not take Fentanyl Orion within 14 days of stopping these medicines – see below for more information.
  • some antihistamines, especially those that make you sleepy (such as chlorpheniramine, clemastine, cyproheptadine, diphenhydramine, or hydroxyzine)
  • certain antibiotics used for infection (such as erythromycin or clarithromycin)
  • antifungal drugs (such as itraconazole, ketoconazole , fluconazole or voriconazole)
  • drugs against HIV – infection’s (such as ritonavir)
  • medicines for irregular heartbeat (such as amiodarone, diltiazem, or verapamil)
  • drugs for tuberculosis (such as rifampicin)
  • certain medicines for epilepsy (such as carbamazepine, phenobarbital, or phenytoin)
  • certain medicines for nausea or motion sickness (such as phenothiazines)
  • certain medicines for heartburn or stomach ulcers (such as cimetidine)
  • certain medicines for angina (chest pain) or high blood pressure (such as nicardipine)
  • certain medicines used to treat blood cancer (such as idelalisib).

Concomitant use of Fentanyl Orion and sedatives, such as benzodiazepines or similar drugs, increases the risk of drowsiness, difficulty breathing ( respiratory depression ), and coma, which can be life-threatening. Due to this, concomitant use should only be considered when other treatment options are not possible.

If your doctor prescribes Fentanyl Orion at the same time as sedatives, the dose and treatment time should be limited.

Tell your doctor if you are taking any sedatives and carefully follow your doctor’s dose recommendations. It may be helpful to inform friends or relatives about paying attention to the signs and symptoms described above. Contact a doctor if you experience any of these symptoms.

Fentanyl Orion with antidepressants The 
risk of side effects is increased if you take medicines such as certain antidepressants. Fentanyl Orion may interact with these medicines and you may find that your mental status changes so that you, for example, feel anxious or see, feel, hear or smell something that does not exist (hallucinations) and experience other effects such as altered blood pressure, fast heartbeat, high body temperature, overactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting, and diarrhea.


If you think you are getting anesthesia, tell your doctor or dentist that you are using Fentanyl Orion.

Fentanyl Orion with food, drink, and alcohol

Do not drink alcohol while taking Fentanyl Orion unless you have first talked to your doctor.

Fentanyl Orion may make you sleepy and you may breathe more slowly. If you drink alcohol, these effects will be aggravated.

Pregnancy, breastfeeding, 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.

Fentanyl Orion should not be used during pregnancy unless you have first discussed it with your doctor.

Fentanyl Orion should not be used during childbirth, as it may affect the breathing of the newborn baby.

Do not use Fentanyl Orion if you are breast-feeding. You should not breast-feed for 3 days after removing the Fentanyl Orion transdermal patch. The reason for this is that the drug can pass into breast milk

Driving and using machines

Fentanyl Orion may affect your ability to drive and use machines or tools as it may make you drowsy or dizzy. If this happens, do not drive or use any tools or machines. Do not drive while using this medicine until you know how it affects you.

If you are not sure if it is safe for you to drive a vehicle while you are taking this medicine, talk to your doctor or pharmacist.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.

  • You should change your patch every three days unless your doctor has told you otherwise.

  • Check from time to time if the patch remains on the skin.

  • Observe your child very closely for 48 hours after:
    • The first patch has been applied
    • A higher dose patch has been applied.
  • It may take some time for the patch to take full effect. Therefore, your child may also need to take other painkillers before the patches take effect. Your doctor will talk to you about this.

Adults and children:

Do not attach the patch

  • The same place twice in a row
  • Skin surfaces that move a lot (joints), skin that is irritated or has sores
  • Skin with a lot of hair. If there is hair, do not shave it off (shaving irritates the skin). Instead, cut the hair as close to the skin as possible.

Put on a patch

Step 1: Prepare the skin

  • Make sure the skin is completely dry, clean, and cool before applying the patch.
  • If you need to clean your skin, use only cold water.
  • Do not use soap or other detergents, creams, moisturizing lotions, oils, or talcum powder before applying the patch.
  • Do not apply a patch immediately after a hot bath or shower.

Step 2: Open the envelope

step 2
  • Each patch is enclosed in a separate envelope.
  • Find the mark that shows where to cut the envelope (use scissors!)
  • Tear up the package along with the clip.
  • Open the envelope and take out the patch and use it immediately.
  • Save the empty envelope so that you can put your used patch in the latter when the patch is to be thrown away,
  • Each patch should only be used once.
  • Do not remove the patch from the envelope until you are ready to use it.
  • Check that the patch is not damaged.
  • Do not use the patch if it has been split, cut, or looks damaged.
  • Never divide or cut the patch.

Step 3: Pull off and press firmly

step 3-1
step 3-2

  • Press the adhesive side of the patch onto the skin.
  • Remove the other part of the protective film and press the entire patch onto the skin using the palm of your hand.
  • Press for at least 30 seconds. Make sure it fits well, especially at the edges.

Step 4: Discard the patch

  • As soon as you remove the patch, fold it carefully in the middle so that the adhesive side sticks together.
  • Put it back in its original envelope and discard the envelope according to the pharmacist’s instructions.
