Safe Usage Guidelines for Patients

Patients in the UK prescribed fentanyl citrate must follow rigorous security protocols:

  • Never share medication: Fentanyl is calibrated for private tolerance; a dose that is safe for a single person could be deadly for another.
  • Prevent heat sources: For those utilizing spots, external heat (such as hot baths or electrical blankets) can increase the rate of drug absorption, causing overdose.
