The Concept of Opioid Tolerance
One of the most crucial elements of fentanyl dose in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in spot type) is generally contra-indicated for "opioid-naive" clients (those not currently taking regular opioid medication).

- No Cutting: Fentanyl spots need to never ever be cut, as this damages the controlled-release system and releases the whole dosage simultaneously.
