Furthermore, transdermal fentanyl's potency and short duration of action make it popular as an intra-operative and post-operative analgesic in cats and dogs. This is usually done with off-label fentanyl patches manufactured for humans with chronic pain. In 2012, a highly concentrated (50mg/mL) transdermal solution, brand name Recuvyra, has become commercially available for dogs only. It is approved by the Food and Drug Administration to provide four days of analgesia after a single application before surgery. It is not approved for multiple doses or other species. The drug is also approved in Europe.
