Dose Tables
Table 1: Transdermal Patch Strengths (mcg/hour)
These patches are usually changed every 72 hours.
| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard beginning dose for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dosage for escalating chronic pain. |
| 50 mcg/hr | High-strength dosage; needs close monitoring. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Optimum standard patch strength. |

These are used 'as required,' but with rigorous 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
One of the most important elements of fentanyl dose in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in patch form) is normally contra-indicated for "opioid-naive" clients (those not presently taking regular opioid medication).
