It is generally prescribed when other forms of pain relief, such as codeine, tramadol, and even basic morphine, have proven insufficient.

Dose Tables
Table 1: Transdermal Patch Strengths (mcg/hour)
These patches are usually altered every 72 hours.
| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Requirement beginning dose for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dose for escalating chronic pain. |
| 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 utilized 'as required,' however with strict limitations on frequency.
| Formulation 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 versus the cheek |
The Concept of Opioid Tolerance
One of the most vital aspects of fentanyl dosage in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in patch kind) is normally contra-indicated for "opioid-naive" patients (those not currently taking regular opioid medication).
According to NHS protocols, a patient is normally thought about opioid-tolerant if they have actually been taking a minimum of 60mg of oral morphine daily (or an equivalent) for a week or longer. Using a fentanyl patch without this baseline tolerance can lead to fatal respiratory depression.
Negative Effects and Risks
While efficient, fentanyl citrate carries a high danger of negative effects. These are categorised by their frequency and severity.
Common Side Effects:

- Irregularity (often requiring a preventative laxative).

Security Precautions for UK Patients
To manage fentanyl securely in a domestic setting, a number of guidelines need to be followed:
- Avoid External Heat: Patients using spots should avoid electrical blankets, saunas, or hot baths directly on the spot area. Heat increases the rate of absorption, which can lead to an accidental overdose.
- Strict Schedule: Patches ought to be altered at the same time every 3rd day.
- Correct Disposal: Used patches still include considerable amounts 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 away from kids and family pets.
- No Cutting: Fentanyl patches should never be cut, as this destroys the controlled-release system and releases the entire dosage simultaneously.
