Demerol, otherwise known as meperidine, is a schedule II opioid to treat moderate to severe pain. Commonly, the drug is provided intravenously as an injectable, and in some cases, it is supplied as an oral medication. Demerol is given to those patients who are suffering from cancer-related pain, post-surgery pain, and other situations where severe pain cannot be treated with non-narcotic medications.

As an opioid with strong effects, Demerol is not recommended for long-term use. Aside from pain relief, an individual taking Demerol can experience effects such as strong sedation and feelings of euphoria. Thus, people who use the drug long-term can suffer from tolerance, dependency, and addiction.

If you or a loved one seems to be abusing Demerol, it is crucial to seek professional help as soon as possible. High doses of the drug can lead to life-threatening overdose and death. Below, you will find information on what does Demerol look like, its typical doses, and how to get help for substance use disorder.
