| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard beginning dosage for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dose for intensifying persistent pain. |
| 50 mcg/hr | High-strength dosage; requires close tracking. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Maximum basic patch strength. |

These are used 'as required,' however with strict limitations on frequency.
| Solution Type | Typical Strengths (mcg) | Administration Route |

The Concept of Opioid Tolerance
One of the most important aspects 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" patients (those not currently taking routine opioid medication).
According to NHS procedures, a client is generally considered opioid-tolerant if they have actually been taking at least 60mg of oral morphine day-to-day (or a comparable) for a week or longer. Using a fentanyl spot without this standard tolerance can result in fatal respiratory anxiety.
Side Effects and Risks

Security Precautions for UK Patients
To handle fentanyl safely in a domestic setting, a number of rules need to be followed:

- Stringent Schedule: Patches must be altered at the same time every third day.
- Correct Disposal: Used patches still consist of substantial quantities of fentanyl. In the UK, it is encouraged to fold them in half (sticky sides together) and return them to a pharmacy or dispose of them safely away from children and animals.
- No Cutting: Fentanyl patches must never be cut, as this destroys the controlled-release mechanism and launches the whole dosage at the same time.
