Meperidine is used to help relieve moderate to severe pain. It may also be used before and during surgery or other procedures. Meperidine belongs to a class of drugs known as opioid analgesics and is similar to morphine. It works in the brain to change how your body feels and responds to pain. Meperidine should not be used to treat long-term or ongoing pain. It should only be used to treat sudden episodes of moderate to severe pain. See also the Precautions section. This drug is not recommended for use in newborns due to an increased risk of serious side effects. Ask the doctor or pharmacist for details.
