- Hypotension (low high blood pressure).
- Urinary retention.
Major Risks
- Chest Wall Rigidity: Rapid IV infusion of high-dose fentanyl can trigger "Stiff Person Syndrome" or "Woody Chest," where the skeletal muscles of the chest and abdominal area end up being rigid, making ventilation difficult without making use of muscle relaxants.
- Addiction and Misuse: Like all opioids, fentanyl has a high capacity for dependence.
