| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Requirement starting dosage for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dosage for intensifying persistent pain. |
| 50 mcg/hr | High-strength dose; needs close monitoring. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Optimum standard patch strength. |

These are utilized 'as required,' however with strict limitations on frequency.
| Formulation Type | Common Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |

| Lozenge (e.g., Actiq) | 200, 400, 600, 800, 1200, 1600 | Dissolved against the cheek |
The Concept of Opioid Tolerance
One of the most important elements of fentanyl dose in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in spot form) is usually contra-indicated for "opioid-naive" patients (those not currently taking regular opioid medication).
