Side Effects of Meperidine (Demerol)

Meperidine, available as the brand Demerol, is an opioid or narcotic medication which is used to manage moderate-to-severe pain. Demerol primarly acts in the central nervous system (CNS) to relieve pain.

Before Taking Demerol

The FDA advisies to inform your healthcare provider if you have:

 

  • Breathing problems or lung diseases
  • A history of drug abuse, alcohol addiction, or mental illness
  • Brain tumor, or seizures
  • A blockage in your stomach or intestines
  • Sickle cell anemia
  • A history of head injury, adrenal gland or urination problems
  • Liver or kidney disease
  • Problems with the gallbladderor thyroid, or curvature of the spine that affects breathing

Serious Side Effects

According to the FDA, dangerous side effects or death can occur when alcohol is combined with Demerol. Your thinking or reactions may be impaired by Demerol and driving or operating machinery should be avoided. Remain vigilant for the risks of falls or other accidents due to dizziness or severe sleepiness. Demerol can slow or stop your breathing causing life-threatening respiratory depression. Risk of respiratory depression is highest when starting Demerol, or when its dose is increased, and it can also occur at recommended doses. Demerol is a controlled substance and has the risks of abuse, misuse, and addiction like other opioid medicines used for pain. Demerol can result in habit-formation (addiction), and abuse which can lead to overdose or death. Demerol should never be shared with another person, especially someone with a history of drug abuse or addiction.

About Pharmacogenetic Testing

Pharmacogenetics is the study of how gene variations in the body affect the processing of drugs. Individuals who do not process drugs well are considered “poor metabolizers” more prone to severe side effects. “Extensive metabolizers” may not feel the medications’s benefits because they break down the body faster than normal. Being a poor metabolizer or extensive metabolizer creates problems for healthcare providers.
