Is there a generic for Demerol (meperidine)?
“Demerol” is a brand name for meperidine, an opioid pain medicine. Generic meperidine products are available in many markets, typically sold as “meperidine HCl” (the salt form). The generic name you would search for is “meperidine” (often “meperidine hydrochloride”).
What generic names should I look for on a pharmacy label?
At the pharmacy, the active ingredient will usually be listed as:
- meperidine (commonly shown as meperidine hydrochloride, “HCl”)
That is the generic equivalent of Demerol.
Is meperidine still prescribed, and why do people look for generics?
Meperidine has long been used for moderate to severe pain, but it is often avoided for routine use in many settings because it can cause serious side effects (including neurotoxicity from a metabolite called normeperidine). That can make prescribers rely on alternatives more often, even when a generic is available.
What to know about switching from Demerol to generic meperidine
A generic switch usually changes the manufacturer and pill strength/appearance, but the active ingredient should be the same. Key practical checks include:
- the strength (mg) and dosing schedule on the prescription
- whether the formulation is immediate-release versus any special formulation (most meperidine is used as a standard opioid formulation)
- any tablet vs liquid differences, which can affect how you measure a dose
Safety issues patients ask about (common with meperidine)
People often look up Demerol/generic meperidine because of safety concerns. Common questions include:
- “Is it safe to take with other sedatives?” (opioids can be dangerous with alcohol, benzodiazepines, and other sedating drugs)
- “How often can it be taken?” (meperidine dosing is tightly controlled because of metabolite-related risks)
- “Why do clinicians avoid it?” (side-effect profile and higher risk compared with many other opioids)
If you tell me your country (US, Canada, UK, etc.) and the dosage form you have (tablet, injection, liquid), I can help you identify the exact generic wording you’re likely to see and what to ask the pharmacist about dosing equivalence.
