• Onset of Action: 1-- 2 minutes (Intravenous).
• Peak Effect: 3-- 5 minutes.
• Period: 30-- 60 minutes (much shorter than morphine due to redistribution into fat and muscle).
• Metabolism: Hepatic through the CYP3A4 enzyme system.
• Excretion: Primarily kidney.

• Prescribing: All prescriptions should fulfill specific legal requirements, including the total amount composed in both words and figures.
• Damage: Expired or polluted vials must be "rendered irretrievable" in the existence of an authorized witness.

Common Side Effects and Adverse Reactions

While extremely reliable, fentanyl citrate brings a risk of significant adverse effects, particularly if not titrated carefully.

Cardiovascular System:Fentanyl can cause bradycardia (sluggish heart rate) and hypotension, though it is generally considered more cardiovascularly steady than morphine.

Musculoskeletal System:A special adverse effects of rapid, high-dose fentanyl administration is "wood chest syndrome" (skeletal muscle rigidity), which can make mechanical ventilation tough.
