Transdermal fentanyl matrix patches Matrifen and Durogesic DTrans are bioequivalent.

In young children, the upper back is furogesic preferred location to minimise the potential of the child removing the patch. The minimum effective fentanyl concentration depends on the pain intensity and the previous use of opioid therapy.

Depending on the additional analgesic needs and the pain status of the child, it may be decided to increase the dose. All patients should be advised to avoid exposing the Durogesic DTrans application site to direct external heat sources such as heating pads, electric blankets, heated water beds, heat or tanning lamps, sunbathing, hot water bottles, prolonged hot baths, saunas and hot whirlpool spa baths.

By the end of the second hour application, a steady-state serum concentration is reached and is maintained during subsequent applications of a patch of the same size. If the analgesic effect of Durogesic DTrans is insufficient, supplementary morphine or another short-duration opioid should be administered.

Accidental exposure by patch transfer Accidental transfer of a fentanyl patch to the skin of a non-patch wearer particularly a childwhile sharing a bed or being in close physical contact with a patch dtrand, may result in an opioid overdose for the non-patch wearer.


Your doctor will talk to you about this. Some parts of the site may not work properly if you choose not to accept cookies. Recommended starting dosage of Durogesic DTrans based upon daily oral morphine dose for patients who have a need for opioid rotation or for clinically less stable duroyesic Patients can then switch to Durogesic DTrans.

Acute or postoperative pain because there is no opportunity for dose titration during short-term use and because serious or life-threatening hypoventilation could result. The pharmacokinetics of transdermal fentanyl do not change with repeated application. Avoid touching the adhesive side of the patch. If you are not sure, talk to your doctor or pharmacist before durogeisc Durogesic DTrans.

Symptoms and signs The manifestations of fentanyl overdose are an extension of its pharmacologic actions, the most serious effect being respiratory depression. Standard reproductive and developmental toxicity studies have been carried out using parenteral administration of fentanyl. Fentanyl concentrations were measured in more than children aged 2 to 17 years who were applied fentanyl patches in the dose range of The Durogesic DTrans patch should be replaced every 72 hours.

Respiratory, thoracic and mediastinal disorders. Equianalgesic potency conversion In patients currently taking opioid analgesics, the starting dose of Durogesic DTrans should be based on the daily dose of the prior opioid.

Reproductive system and breast disorders. Therefore, the durogessic use of Durogesic DTrans and CYP3A4 inhibitors is not recommended unless the benefits outweigh the increased risk of adverse effects.

Neonatal withdrawal syndrome has been reported in newborn infants with chronic maternal use of Durogesic DTrans during pregnancy.


Hepatic impairment Because fentanyl is metabolised to inactive metabolites in the liver, hepatic impairment might delay its elimination. Find out more here.

Demystifying Opioid Conversion Calculations: These subjects received at least one dose of Durogesic DTrans and provided safety data see section 5. Search the site Search. In a study on pre- and postnatal development the survival rate of offspring was significantly reduced at doses which slightly reduced maternal weight. If you do, you may increase the amount of medicine you get from the patch.

Musculoskeletal and connective tissue disorders. In two paediatric studies, the required fentanyl transdermal patch dose was calculated conservatively: Xospata Xospata gilteritinib is a kinase inhibitor indicated for the treatment of patients who have relapsed or Interactions with other medicinal products CYP3A4 inhibitors The concomitant use of Durogesic DTrans with cytochrome P 3A4 CYP3A4 inhibitors may result in an increase in fentanyl plasma concentrations, which could increase or prolong both the therapeutic and adverse effects, and may cause serious respiratory depression.

Non-epileptic myo clonic reactions can occur. To guard against accidental ingestion by children, use caution when choosing the application site for Durogesic DTrans see sections 4. Fentanyl citrate is used parenterally to provide preoperative anxiolysis and sedation and as a supplement to anesthesia.

There is a potential for temperature-dependent increases in fentanyl released from the system resulting in possible overdose and death. Paediatric population Interaction studies have only been performed in adults.
