What is Entereg (alvimopan), and what would an “Entereg generic” be?
Entereg is the brand name for alvimopan, a drug used to help reduce opioid-related bowel dysfunction (specifically postoperative ileus) in certain settings related to surgery. An “Entereg generic” would mean a generic version of alvimopan approved by regulators and sold under a different name, typically “alvimopan” plus a manufacturer label.
Is there currently a generic for Entereg (alvimopan)?
I don’t have enough provided information to confirm whether a generic Entereg (alvimopan) is currently available, who makes it, or what exact product names/strengths are on the market. If you share your country (US, Canada, UK, EU, etc.) or the strength/form you need, I can narrow the answer to the right market.
How do you ask for it at a pharmacy?
If you’re trying to fill a generic, ask for:
- “Alvimopan” (generic name), and
- the dose/strength matching your Entereg prescription.
Pharmacies generally substitute only with an approved interchangeable/generic product where permitted.
What to check before switching from Entereg to generic alvimopan
When substituting, confirm your prescription details match:
- Active ingredient: alvimopan
- Dose/strength: must match
- Formulation and dosing schedule: postop use depends on the regimen
- Coverage/interchange rules: varies by country and insurer
If the generic is not available, the pharmacist may need to order it or discuss alternatives.
Alternatives if alvimopan/Entereg isn’t available
If you cannot get alvimopan, the pharmacy or prescribing clinician may consider other approaches to postoperative bowel function depending on your surgery type and hospital protocol (the exact alternative depends on local standards and your medical situation).
