| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard beginning dose for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dose for intensifying persistent discomfort. |
| 50 mcg/hr | High-strength dosage; requires close monitoring. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Maximum basic spot strength. |

These are utilized 'as needed,' but with rigorous limitations 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 crucial elements of fentanyl dosage in the UK is the requirement for opioid tolerance. Fentanyl citrate (especially in patch kind) is generally contra-indicated for "opioid-naive" patients (those not currently taking regular opioid medication).

Security Precautions for UK Patients
To manage fentanyl safely in a domestic setting, a number of rules need to be followed:

- No Cutting: Fentanyl spots need to never be cut, as this damages the controlled-release mechanism and releases the whole dosage at once.
