Meperidine is a strong prescription opioid pain medicine (also known as meperidine hydrochloride or pethidine) used to relieve moderate to severe pain when opioid treatment is needed. It is a controlled substance because it can be misused or lead to dependence, and it is intended for short-term use rather than long-lasting chronic pain. It works by acting on the central nervous system and pain receptors to change how the brain and body sense pain.
