Is Relistor considered expensive compared with other constipation treatments?
Relistor (methylnaltrexone) is typically seen as a higher-cost prescription option because it’s a branded, opioid-reversal medication used when opioids cause constipation. Whether it feels “expensive” often depends on your insurance coverage and whether you’re paying cash or a copay.
In practice, patients may find that it costs more than standard constipation options like over-the-counter laxatives, but less than (or more than) other prescription therapies depending on the specific alternative and payer.
What drives the price of Relistor?
The cost is usually determined by several factors:
- Whether you’re using insurance vs. paying out of pocket (cash prices for branded drugs are often much higher).
- The dose and form (commonly injectable vs. oral/other formulations depending on what’s available and prescribed).
- Your plan’s tier and whether prior authorization is required.
- Pharmacy type (retail vs. specialty pharmacy) and negotiated discounts.
Does it cost the same everywhere?
No. Pricing can vary by:
- Pharmacy and region
- Manufacturer and wholesaler pricing
- Insurance negotiated rates and copays
- Availability of patient assistance programs

What if you think Relistor is too expensive?
Common next steps people take with their clinician/pharmacy include:
- Asking your prescriber whether prior authorization documentation can help approval.
- Asking if there’s a preferred alternative on your formulary (other prescription constipation therapies or different opioid-induced constipation approaches).
- Checking for manufacturer copay assistance or patient support programs (if available for your plan and location).
What’s the real-world bottom line?
Relistor is generally considered expensive relative to many first-line constipation options, but the out-of-pocket cost for an individual patient can be low or moderate with insurance. The main deciding factor is your coverage and copay, not just the drug’s list price.
