  • It cannot be legally obtained without a physician’s prescription.

Also known as pethidine, it was discovered in 1939 by a German chemist who was trying to synthesize an anticholinergic agent. Meperidine’s analgesic properties were later recognized by another chemist working for a German pharmaceutical company.


It should not be used for treatment of chronic pain. This drug should only be used in the treatment of acute episodes of moderate to severe pain Prolonged use may increase the risk of toxicity.

Over 70,000 overdose deaths were reported in the United States in 2017. Opioids were the current leading causes of these deaths, with opioid abuse responsible for 47,500 overdose deaths. States with the highest numbers of opioid overdose deaths are Ohio, West Virginia, Washington, D.C., Kentucky and Pennsylvania.

Nearly 75 percent of heroin users began using heroin after they were prescribed opioid analgesics and could no longer get a prescription for them from a doctor.Another leading cause of opioid addiction is people sharing unused prescription pain relievers with family members and friends. Research shows that many adolescents abuse this drug and other pain pills that are given to them by family members.

The World Health Organization reports that effective treatments involving intensive counseling and medications like Vivitrol for an opioid addiction exists but only about eight percent of people needing treatment are receiving it.


By acting on opioid receptors in the brain, Meperidine users experience the same side effects produced by other opioids such as Vicodin, hydrocodone, morphine and heroin.

In fact, opioids are so addicting that non-cancer patients with only a one-day supply may cause six percent of these patients to become addicted. Furthermore, the chance of someone abusing opioids increases significantly during the first few days of taking them.

  • This same report from CBS News also states that people taking it or other opioids for two weeks have a 13 percent risk of addiction to the drug.
