Fentanyl zur Schmerzlinderung

Über Fentanyl

What is fentanyl used for?

Fentanyl is a strong opioid painkiller that is used to treat severe or chronic pain.

If you have long-term (chronic) pain, you may be prescribed a fentanyl skin patch. This is called transdermal fentanyl. The patch releases fentanyl slowly over time to give continuous pain relief.

Sometimes, pain may still break through. This is called breakthrough pain. In these cases, fentanyl may be given in other forms, such as lozenges, tablets, films, or nasal sprays, which are taken when needed for fast pain relief.

Fentanyl can also be given as an injection during surgery to help control pain.

How does fentanyl work?

It works by binding to certain tiny areas, called opioid receptors, in your brain and spinal cord (central nervous system). This leads to a decrease in the way you feel pain and your reaction to pain.

Side effects of fentanyl

Common side effects of fentanyl include:

• Verstopfung.

• Ich fühle mich krank.

• Krank sein (Erbrechen).

• Ich fühle mich schwindelig.

• Sie fühlen sich schläfrig oder müde.

• Stomach (tummy) pain.

Eine vollständige Liste finden Sie in der Packungsbeilage des Herstellers, die Ihrem Arzneimittel beiliegt.

The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any side effects continue or become troublesome.

Who should not take fentanyl?

Some medicines are not suitable for people with certain conditions. Before taking fentanyl it is important that your doctor knows:

• Wenn Sie schwanger sind oder stillen.

• Wenn Sie ein Problem mit der Funktionsweise Ihrer Leber oder mit der Funktionsweise Ihrer Nieren haben.

• If you have a sore mouth or diabetes. This is because some brands of fentanyl may not be suitable for you to take.

• Wenn Sie Prostataprobleme oder Schwierigkeiten beim Wasserlassen haben.

• If you have any breathing problems, such as asthma or chronic obstructive pulmonary disease (COPD).

• If you have been told you have low blood pressure.

• Wenn Sie Probleme mit Ihrer Schilddrüse oder den Nebennieren haben.

• If you have epilepsy.

• Wenn Sie ein Problem mit Ihrem Gallengang haben.

• Wenn Sie seit mehr als einer Woche unter Verstopfung leiden oder ein entzündliches Darmproblem haben.

• If you have a condition causing muscle weakness, called myasthenia gravis.

• Wenn Sie kürzlich eine schwere Kopfverletzung erlitten haben oder einen Hirntumor haben.

• Wenn Sie jemals von Drogen oder Alkohol abhängig waren.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

Wie man Fentanyl verwendet

• Use fentanyl exactly as prescribed by your doctor.

• Fentanyl comes in different forms, so your doctor or pharmacist will explain how to use yours.

• When you first start fentanyl, your dose is usually increased gradually to find the right level for your pain and reduce side effects.

• Once the correct dose is found, keep using the same dose unless your doctor tells you to change it.

• Check the label on the pack for your dose and follow the instructions carefully.

• If you are unsure about the dose or how to use it, ask your pharmacist for advice.

Wenn Sie Fentanylpflaster verwenden

• Open the pouch carefully and check the patch is not damaged. Keep the pouch to safely dispose of the patch later.

• Apply to clean, dry, healthy skin on your upper arm or upper body. Press firmly for about 30 seconds, especially around the edges. Avoid touching the sticky side. Wash your hands after applying.

• It may take up to 24 hours for the patch to reach full effect, so you may need other pain relief during this time.

• Leave the patch on for 72 hours (3 days). After this, remove it and apply a new patch to a different area. Change it at the same time of day each time.

• Dispose of used patches safely: fold it sticky side inwards, put it in the pouch, and follow your doctor’s instructions. Keep out of reach of children.

• Avoid heat sources on the patch, such as heating pads, hot water bottles, electric blankets, heated water beds, long hot baths, saunas, or sunbathing. Heat can release too much fentanyl and increase the risk of overdose.

• Tell your doctor if you develop a high temperature, as this can also increase fentanyl absorption.

• Always check your brand when getting a new prescription. Different brands may release fentanyl differently; stick to the same brand unless your doctor advises otherwise.

• Watch for signs of too much fentanyl: shallow or weak breathing, extreme sleepiness, confusion, slurred speech, or severe dizziness. If these happen, remove the patch and contact your doctor immediately.

Wenn Sie Fentanyl-Lutschtabletten (Actiq®) verwenden

• If your mouth is dry, moisten it with water before using the lozenge.

• Suck one lozenge over about 15 minutes.

• If your pain has not eased within 15 minutes after finishing the lozenge, you may suck another one.

• If your pain is not controlled, tell your doctor.

Das Beste aus Ihrer Behandlung herausholen

• Do not drink alcohol while taking fentanyl. Alcohol can increase side effects like dizziness and sleepiness.

• Fentanyl is only given for as long as needed. Long-term use can cause tolerance (the medicine works less) and dependence, which may lead to withdrawal symptoms if it is stopped suddenly. Your doctor will reduce your dose gradually when it’s no longer needed.

• Fentanyl can slow your reactions. Do not drive if you feel drowsy or dizzy. Even if you feel safe, carry proof that fentanyl is prescribed (such as prescription slip or patient leaflet).

• Tell your doctor, dentist, or other healthcare professional that you are taking fentanyl before having any procedures or dental treatment.

• Before taking other medicines check with a pharmacist that they are safe to take with fentanyl.

• Fentanyl is a controlled drug, so carry a letter from your doctor when travelling. For trips longer than three months, you must apply to the Home Office for a licence to take fentanyl with you.

Wie lagert man Fentanyl?

• Bewahren Sie alle Arzneimittel außerhalb der Reichweite und Sichtweite von Kindern auf. Dies gilt auch für gebrauchte Pflaster und halbfertige Lutschtabletten.

• An einem kühlen, trockenen Ort aufbewahren, vor direkter Hitze und Licht schützen.

Häufig gestellte Fragen

How long does it take for fentanyl to work?

Fentanyl usually starts to work within minutes, although the exact timing depends on how it is taken. Injected fentanyl works in 1-5 minutes, lozenges or nasal sprays in 5-15 minutes, and fentanyl patches begin providing pain relief after 12-24 hours.

How long does fentanyl stay in your system?

Fentanyl can stay in your system for 1 to 3 days, depending on dose and method of use. It is typically detectable for up to 24 hours in blood, 1-3 days in urine, 48 hours in saliva, and up to 90 days in hair. Fentanyl patches may cause longer-lasting effects.

Is fentanyl addictive?

Yes, fentanyl is highly addictive, even when prescribed. It is a strong opioid painkiller that can cause physical dependence, tolerance, and opioid addiction, particularly with long-term or non-medical use.

Is fentanyl stronger than morphine?

Yes, fentanyl is much stronger than morphine. It is around 50 to 100 times more potent, meaning much smaller doses are needed to achieve the same level of pain relief.

What happens when you stop taking fentanyl?

Stopping fentanyl suddenly can cause withdrawal symptoms. Common symptoms include muscle aches, anxiety, sweating, feeling sick, diarrhoea, and sleep problems. Doctors usually recommend gradually reducing the dose to minimise withdrawal.
