Dose Tables
Table 1: Transdermal Patch Strengths (mcg/hour)
These spots are normally altered every 72 hours.
| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard starting dosage for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dosage for escalating persistent discomfort. |
| 50 mcg/hr | High-strength dosage; requires close tracking. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Optimum basic patch strength. |
Table 2: Transmucosal Formulations for Breakthrough Pain
These are used 'as needed,' however with stringent limits on frequency.
| Formula Type | Typical Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |
| Buccal Tablet | 100, 200, 400, 600, 800 | Between cheek and gum |
| Lozenge (e.g., Actiq) | 200, 400, 600, 800, 1200, 1600 | Liquified against the cheek |
The Concept of Opioid Tolerance
Among the most vital elements of fentanyl dosage in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in spot kind) is normally contra-indicated for "opioid-naive" clients (those not currently taking routine opioid medication).

Safety Precautions for UK Patients
