How Fentanyl Works

Fentanyl functions as a potent agonist of opioid receptors in the central nervous system, producing analgesia by altering the perception of and response to pain signals. It primarily acts on mu-opioid receptors, leading to inhibition of neurotransmitter release, resulting in pain relief and sedation.

Side Effects of Fentanyl

Common side effects may include nausea, vomiting, constipation, drowsiness, and respiratory depression. Serious side effects can include slowed heart rate, low blood pressure, and potentially fatal respiratory depression.

Information About Fentanyl

Fentanyl is a potent synthetic opioid used to manage severe chronic pain in opioid-tolerant patients and as anaesthetic analgesia in Singapore. Available as a 12mcg–100mcg transdermal patch changed every 72 hours or as an intravenous formulation for procedural use under clinical supervision, it is HSA-registered and available on prescription only in Singapore. The transdermal patch is reserved exclusively for opioid-tolerant patients as it releases continuous high-dose fentanyl — accidental exposure in opioid-naive individuals including children can cause fatal respiratory depression. A valid doctor's consultation is required before dispensing. Order Fentanyl online at DoctorOnCall Singapore with same-day delivery available.
