Dose Tables
Table 1: Transdermal Patch Strengths (mcg/hour)
These patches are normally altered every 72 hours.
| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard starting dosage for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dosage for intensifying persistent pain. |
| 50 mcg/hr | High-strength dosage; needs close monitoring. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Maximum standard patch strength. |
Table 2: Transmucosal Formulations for Breakthrough Pain
These are utilized 'as required,' but with strict limitations 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 | Dissolved against the cheek |
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 (particularly in patch type) is normally contra-indicated for "opioid-naive" patients (those not currently taking routine opioid medication).

Safety Precautions for UK Patients
To handle fentanyl securely in a domestic setting, several guidelines should be followed:

- Correct Disposal: Used spots still contain significant quantities of fentanyl. In the UK, it is advised to fold them in half (sticky sides together) and return them to a pharmacy or deal with them safely away from children and family pets.
- No Cutting: Fentanyl patches need to never be cut, as this destroys the controlled-release system and releases the whole dose simultaneously.
