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 (especially in spot kind) is typically contra-indicated for "opioid-naive" clients (those not currently taking routine opioid medication).

- Correct Disposal: Used spots still include considerable amounts of fentanyl. In the UK, it is advised to fold them in half (sticky sides together) and return them to a pharmacy or deal with them safely far from children and pets.
- No Cutting: Fentanyl spots must never ever be cut, as this ruins the controlled-release system and releases the whole dose at when.
