Dose Tables
Table 1: Transdermal Patch Strengths (mcg/hour)
These patches are usually altered every 72 hours.
| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Requirement beginning dosage for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dose for escalating persistent discomfort. |
| 50 mcg/hr | High-strength dosage; requires close monitoring. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Maximum basic patch strength. |

These are used 'as required,' however with stringent limitations 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 aspects of fentanyl dose in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in patch kind) is typically contra-indicated for "opioid-naive" clients (those not presently taking routine opioid medication).
According to NHS procedures, a patient is normally considered opioid-tolerant if they have been taking at least 60mg of oral morphine daily (or an equivalent) for a week or longer. Utilizing a fentanyl spot without this baseline tolerance can lead to fatal breathing depression.
Negative Effects and Risks

Security Precautions for UK Patients
