Fentanyl citrate – an opioid pain medicine used to treat “breakthrough” cancer pain not controlled by other medicines. Moreover not for treating pain not cancer-related.
Fentanyl is a powerful pain medication. It is an opioid, like morphine, codeine, oxycodone (oxys) and methadone. Also most often prescribed as a slow-release patch to people with long-term, severe pain. When used in this way, it can be very effective and safe.
Thus much stronger than most other opioids—up to 100 times stronger than morphine—and very dangerous if misused. Even a small amount can cause an overdose and death.
Fentanyl – also used as a recreational drug, and this use has led to thousands of overdose deaths each year in recent years. Deaths have also resulted from improper medical use. Fentanyl has a relatively wide therapeutic index (270) which makes it a very safe surgical anesthetic when monitored carefully; however, its extreme potency requires careful measurements of highly diluted fentanyl in solution; attempting to accurately measure a dose of pure fentanyl powder is impractical without advanced scientific equipment as an effective dose and a lethal dose of fentanyl powder placed next to each other would be difficult or impossible to differentiate with the naked eye.
