While it is available in different types, consisting of patches, lozenges, and tablets, the nasal spray formula is specifically created for fast absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), allowing the medication to enter the bloodstream straight, bypassing the digestion system and the "first-pass metabolic process" of the liver. Fentanyl Test Kit UK results in a fast onset of action, normally within 5 to 10 minutes, making it perfect for treating intense flares of pain.

| Period | Short (approx. 1-2 hours) | Moderate (approx. 2-4 hours) | Long (72 hours) |
| Invasiveness | Non-invasive (Nasal) | Non-invasive (Oral) | Non-invasive (Skin) |
