What Fentanyl Ratiopharm transdermal patch is and what it is used for

The name of your medicine is Fentanyl Ratiopharm.

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 ratiopharm contains a substance called fentanyl . It belongs to a group of strong painkillers called opioids.

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

What you need to know before using Fentanyl Ratiopharm transdermal patch

Do not use Fentanyl Ratiopharm transdermal patches

  • if you are allergic to fentanyl 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 Fentanylratiopharm.

Warnings and cautions

Fentanyl Ratiopharm can cause life-threatening side effects in people who are not already regularly taking prescription opioid medicines. Fentanyl Ratiopharm 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.

Depot patches that have adhered 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 Ratiopharm

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

  • Have you ever had problems with your lungs or breathing?
  • Have you ever had problems with your heart, liver, kidneys, or had low blood pressure?
  • You’ve ever had a brain tumor
  • Have you 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
  • Have you 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 Ratiopharm.

Side effects and Fentanyl ratiopharm

  • Fentanyl Ratiopharm can 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 Ratiopharm 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 Ratiopharm, tell your doctor – it may cause an increased amount of medicine to pass through your skin.
  • Fentanyl ratiopharm can 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.

The patches should not be cut into smaller pieces as the quality, efficacy, and safety of split patches have not been demonstrated.

Other medicines and Fentanyl ratopharm transdermal patches

Fentanyl Ratiopharm with sedatives such as benzodiazepines or similar medicines

Concomitant use of Fentanyl Ratiopharm and sedatives or medicines for insomnia such as benzodiazepines or similar medicines increases the risk of drowsiness, difficulty breathing ( breathing depression ), coma and 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 Ratiopharm at the same time as sedatives, the doseand treatment time should be limited by your doctor.

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 Ratiopharm with antidepressants

Here you put on the patch


Apply the patch on a flat part of your upper body or arm (not over a joint).


  • Always put the patch on the upper back so that the child does not have access to or remove the patch.
  • Check from time to time if the patch remains on the skin.
  • Your child mustn’t take the patch and put it in his mouth as it can be life-threatening and even fatal.
  • 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

  • Each patch is enclosed in a separate envelope.
  • Tear open the envelope in the slot.
  • Carefully tear off the edge of the envelope completely.

  • Hold both sides of the opened envelope and pull them apart.
  • Take out the patch and apply 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

  • Make sure that the patch will be covered by loose clothing and that it will not sit under a tight or elastic band.
  • Carefully pull one-half of the clear protective film away from the center of the patch. Avoid touching the adhesive side of the patch.
  • Press the adhesive side of the patch onto the skin.
  • Remove the second 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.
  • Keep used patches out of the reach and sight of children – even used patches contain some medicines that can harm children and can even be fatal.

Step 5: Wash

  • Always wash your hands with clean water only after handling the patch.
