What is Demerol (meperidine)?
Demerol is the brand name for meperidine, an opioid pain medicine used to treat moderate to severe pain. It works by changing how the brain and body respond to pain signals. [1]
What is Demerol used for?
Demerol has been used for short-term treatment of significant pain, typically when an opioid is needed. [1]
How is Demerol usually given?
Demerol is administered as a prescription opioid under medical supervision. Common routes include injection (for rapid pain control) and other forms depending on the specific product and clinical setting. [1]
What are the major risks and side effects people ask about?
Like other opioids, Demerol can cause common opioid side effects such as sleepiness, dizziness, constipation, and nausea. It can also cause serious risks, including respiratory depression (slowed or stopped breathing), especially if taken incorrectly or combined with other depressants. [1]
Why do clinicians warn about Demerol (meperidine) compared with other opioids?
A key issue with meperidine is that it can form a metabolite (normeperidine) that can build up, especially with repeated dosing, kidney impairment, or prolonged use. Accumulation increases the risk of neurologic side effects such as agitation, tremor, and seizures. This is one reason many guidelines favor other opioids for routine pain management. [1][2]
Can you take Demerol with other medicines or alcohol?
Combining Demerol with other substances that slow breathing (such as benzodiazepines, other opioids, or alcohol) increases the risk of overdose and respiratory depression. People should only use Demerol with prescriber guidance about other medications. [1]
What happens if someone overdoses on Demerol?
An opioid overdose can be life-threatening due to respiratory depression. Symptoms can include extreme sleepiness, slow or irregular breathing, and unresponsiveness. Emergency treatment may involve opioid reversal medications and supportive care. [1]
Is Demerol still widely used today?
Demerol has been used historically, but due to meperidine-specific safety concerns (including metabolite accumulation and seizure risk), many clinicians rely more on alternative opioids for longer or more routine pain control. Use is typically more restricted and carefully monitored. [1][2]
