| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Requirement beginning dose for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dose for escalating persistent pain. |
| 50 mcg/hr | High-strength dose; requires close monitoring. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Optimum standard patch strength. |

These are utilized 'as needed,' however with rigorous limits on frequency.
| Formula 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
Among the most crucial aspects of fentanyl dosage in the UK is the requirement for opioid tolerance. Fentanyl citrate (especially in patch type) is usually contra-indicated for "opioid-naive" patients (those not currently taking regular opioid medication).
According to NHS protocols, a patient is usually thought about opioid-tolerant if they have been taking a minimum of 60mg of oral morphine everyday (or a comparable) for a week or longer. Using a fentanyl patch without this baseline tolerance can cause deadly respiratory depression.
Adverse Effects and Risks
While effective, fentanyl citrate brings a high risk of negative results. These are categorised by their frequency and seriousness.
Common Side Effects:
- Nausea and vomiting (common when starting treatment).
- Irregularity (often needing a preventative laxative).

Security Precautions for UK Patients
To handle fentanyl securely in a domestic setting, a number of rules should be followed:
- Avoid External Heat: Patients wearing patches should prevent electric blankets, saunas, or hot baths directly on the spot area. Heat increases the rate of absorption, which can result in an unintentional overdose.
- Strict Schedule: Patches must be changed at the exact same time every 3rd day.
- Correct Disposal: Used spots still contain substantial quantities of fentanyl. In the UK, it is recommended to fold them in half (sticky sides together) and return them to a pharmacy or deal with them securely far from children and family pets.
- No Cutting: Fentanyl patches should never be cut, as this ruins the controlled-release system and releases the entire dosage simultaneously.
