| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard starting dosage for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dose for intensifying chronic discomfort. |
| 50 mcg/hr | High-strength dosage; requires close tracking. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Optimum basic patch strength. |

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

The Concept of Opioid Tolerance
One of the most critical elements of fentanyl dosage in the UK is the requirement for opioid tolerance. Fentanyl citrate (especially in patch type) is normally contra-indicated for "opioid-naive" patients (those not presently taking routine opioid medication).
According to NHS protocols, a client is normally considered opioid-tolerant if they have actually been taking a minimum of 60mg of oral morphine day-to-day (or a comparable) for a week or longer. Using a fentanyl spot without this standard tolerance can result in deadly respiratory depression.
