Dosage Tables
Table 1: Transdermal Patch Strengths (mcg/hour)

| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Requirement beginning dose for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dosage for intensifying chronic pain. |
| 50 mcg/hr | High-strength dosage; requires close monitoring. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Maximum standard spot strength. |
Table 2: Transmucosal Formulations for Breakthrough Pain
These are used 'as needed,' but with rigorous limits on frequency.
| Solution Type | Common 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 | In between cheek and gum |
| Lozenge (e.g., Actiq) | 200, 400, 600, 800, 1200, 1600 | Dissolved versus the cheek |
The Concept of Opioid Tolerance

Safety Precautions for UK Patients
To handle fentanyl safely in a domestic setting, a number of rules must be followed:
- Avoid External Heat: Patients using spots need to avoid electric blankets, saunas, or hot baths straight on the spot area. Heat increases the rate of absorption, which can lead to an accidental overdose.

- Correct Disposal: Used spots still include substantial amounts of fentanyl. In the UK, it is encouraged to fold them in half (sticky sides together) and return them to a pharmacy or get rid of them securely far from children and pets.
- No Cutting: Fentanyl patches should never ever be cut, as this ruins the controlled-release system and launches the entire dosage at the same time.
