of Fentanyl Citrate
Fentanyl is a synthetic opioid typically used to treat patients with chronic severe pain or severe pain following surgery. Fentanyl is a Schedule II controlled substance that is similar to morphine but about 100 times more potent. Under the supervision of a licensed medical professional, fentanyl has a legitimate medical use. Patients prescribed fentanyl should be monitored for potential misuse or abuse.
Illicit fentanyl, primarily manufactured in foreign clandestine labs and smuggled into the United States through Mexico, is being distributed across the country and sold on the illegal drug market. Fentanyl is being mixed in with other illicit drugs to increase the potency of the drug, sold as powders and nasal sprays, and increasingly pressed into pills made to look like legitimate prescription opioids. Because there is no official oversight or quality control, these counterfeit pills often contain lethal doses of fentanyl, with none of the promised drug.
