These are used 'as needed,' but with rigorous limits on frequency.
| Formula Type | Common Strengths (mcg) | Administration Route |

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 patch kind) is typically contra-indicated for "opioid-naive" clients (those not presently taking routine opioid medication).
