What is Demerol?

Demerol or meperidine is an opioid drug used for the treatment of moderate to severe pain. It is a strong prescription pain medicine for managing pain in the short term when you can not tolerate other pain treatments like non-opioid pain medicines. You can buy Demerol online or from a local pharmacy store.

Important Information

  • If you have serious asthma or breathing difficulties, you should not use Demerol.
  • Do not use Demerol if you used MAO inhibitors such as isocarboxazid, linezolid, phenelzine, methylene blue injection, rasagiline, selegiline, or tranylcypromine in the last 14 days. 
  • Demerol can slow down or stop your breathing and may be habit-forming. You are at high risk for opioid addiction, abuse, and misuse that could lead to death even if you take your dose exactly as prescribed.
  • Using this medicine during pregnancy may lead to life-threatening withdrawal symptoms in the newborn.
  • If you take Demerol with alcohol or other drugs that cause drowsiness or slow breathing, it can lead to fatal side effects.

What to know before taking Demerol?

You should not use Demerol if you are allergic to meperidine, have serious asthma or breathing problems, or stomach or intestine blockages.  If you have used MAO inhibitors in the last 14 days, do not use Demerol. There may be a dangerous drug interaction. MAO inhibitors include isocarboxazid, linezolid, injection of methylene blue, phenelzine, rasagiline, selegiline, tranylcypromine. To make sure Demerol is safe for you, tell your doctor if you ever had:

  • A head injury, brain tumor, or seizures
  • Drug or alcohol addiction, or mental illness
  • Liver or kidney disease
  • Sickle cell anemia
  • Breathing problems, sleep apnea
  • A blockage in your stomach or intestines
  • Urination problems
  • Problems with your gallbladder, adrenal gland, or thyroid
  • Abnormal curvature of the spine that affects breathing

Your baby could become dependent on the medicine if you are using Demerol while you are pregnant. This can lead to life-threatening symptoms of withdrawal after birth in the baby.  Do not breastfeed while taking Demerol. Meperidine can enter the breast milk and cause drowsiness, breathing difficulties, or death in a nursing baby.
