What is Fentanyl Citrate?
Fentanyl citrate communicates with the mu-opioid receptors in the main nerve system to change the understanding of discomfort.

Dosage Tables
Table 1: Transdermal Patch Strengths (mcg/hour)
These spots are typically altered every 72 hours.
| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard beginning dose for opioid-tolerant clients. |
| 25 mcg/hr | Moderate dose for escalating persistent discomfort. |
| 50 mcg/hr | High-strength dose; needs close monitoring. |
| 75 mcg/hr | Advanced discomfort management in palliative care. |
| 100 mcg/hr | Optimum standard patch strength. |

These are used 'as needed,' however with stringent limitations on frequency.
| Solution Type | Typical Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |

| Lozenge (e.g., Actiq) | 200, 400, 600, 800, 1200, 1600 | Dissolved against the cheek |
The Concept of Opioid Tolerance
One of the most important elements of fentanyl dose in the UK is the requirement for opioid tolerance. Fentanyl citrate (especially in patch form) is normally contra-indicated for "opioid-naive" patients (those not currently taking routine opioid medication).
According to NHS procedures, a patient is generally considered opioid-tolerant if they have been taking a minimum of 60mg of oral morphine daily (or a comparable) for a week or longer. Using a fentanyl spot without this standard tolerance can result in deadly breathing anxiety.
Side Effects and Risks
While efficient, fentanyl citrate brings a high risk of negative results. These are categorised by their frequency and seriousness.
Common Side Effects:
- Nausea and throwing up (common when beginning treatment).
- Irregularity (often needing a preventative laxative).
- Somnolence (severe drowsiness).
- Lightheadedness and headaches.

- Addiction and Dependence: As a Class A drug, there is a significant danger of physical and mental reliance.
- Serotonin Syndrome: Can occur if taken along with specific antidepressants (SSRIs or SNRIs).
Safety Precautions for UK Patients
To manage fentanyl safely in a domestic setting, a number of rules need to be followed:
- Avoid External Heat: Patients using patches need to prevent electrical blankets, saunas, or hot baths directly on the patch area. Heat increases the rate of absorption, which can cause an unexpected overdose.
- Stringent Schedule: Patches must be changed at the same time every 3rd day.
- Correct Disposal: Used patches still include significant amounts of fentanyl. In the UK, it is advised to fold them in half (sticky sides together) and return them to a drug store or deal with them securely away from kids and animals.
- No Cutting: Fentanyl spots need to never be cut, as this ruins the controlled-release system and releases the entire dose at the same time.
