| 12 mcg/hr | Requirement beginning dose for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dose for intensifying chronic discomfort. |
| 50 mcg/hr | High-strength dose; needs close tracking. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Maximum basic patch strength. |

These are used 'as needed,' but with stringent limits on frequency.
| Solution Type | Typical Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |

The Concept of Opioid Tolerance
Among the most important elements of fentanyl dose in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in patch type) is typically contra-indicated for "opioid-naive" clients (those not presently taking routine opioid medication).
