Dosage Tables
Table 1: Transdermal Patch Strengths (mcg/hour)
These patches are typically altered every 72 hours.
| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard starting dose for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dosage for escalating chronic pain. |
| 50 mcg/hr | High-strength dose; needs close monitoring. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Optimum basic spot strength. |
Table 2: Transmucosal Formulations for Breakthrough Pain
These are used 'as needed,' but with stringent limitations on frequency.
| Formula 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 | Between cheek and gum |
| Lozenge (e.g., Actiq) | 200, 400, 600, 800, 1200, 1600 | Dissolved versus the cheek |
The Concept of Opioid Tolerance
Among the most crucial aspects of fentanyl dose in the UK is the requirement for opioid tolerance. Fentanyl citrate (particularly in patch form) is usually contra-indicated for "opioid-naive" patients (those not presently taking routine opioid medication).
According to NHS procedures, a client is usually thought about opioid-tolerant if they have actually been taking a minimum of 60mg of oral morphine day-to-day (or an equivalent) for a week or longer. Using a fentanyl spot without this baseline tolerance can cause deadly breathing depression.
Negative Effects and Risks
While effective, fentanyl citrate carries a high risk of adverse effects. These are categorised by their frequency and seriousness.

- Addiction and Dependence: As a Class A drug, there is a significant danger of physical and mental dependence.
- Serotonin Syndrome: Can occur if taken alongside certain antidepressants (SSRIs or SNRIs).
Security Precautions for UK Patients
To handle fentanyl safely in a domestic setting, several guidelines need to be followed:
- Avoid External Heat: Patients wearing spots must prevent electric blankets, saunas, or hot baths directly on the patch location. Heat increases the rate of absorption, which can cause an accidental overdose.
- Stringent Schedule: Patches needs to be altered at the same time every third day.
- Correct Disposal: Used patches still consist of substantial amounts of fentanyl. In the UK, it is advised to fold them in half (sticky sides together) and return them to a pharmacy or dispose of them safely away from children and family pets.
- No Cutting: Fentanyl spots must never ever be cut, as this destroys the controlled-release mechanism and releases the entire dose at once.
Often Asked Questions (FAQ)
1. What should I do if I miss a patch change?
