UK health agencies have actually responded by increasing the schedule of Naloxone, an emergency medication that can reverse the results of an opioid overdose, to first responders and drug treatment centres.

Safe Usage Guidelines for Patients

Clients in the UK prescribed fentanyl citrate should follow rigorous security procedures:

• Never share medication: Fentanyl is adjusted for specific tolerance; a dosage that is safe for one individual might be deadly for another.
• Avoid heat sources: For those using spots, external heat (such as hot baths or electrical blankets) can increase the rate of drug absorption, resulting in overdose.
