Is there a generic of Hetlioz (tasimelteon) available yet?
Hetlioz is the brand name for tasimelteon, a medication used to treat non-24-hour sleep-wake disorder in blind patients. Whether a “Hetlioz generic” is available depends on when the drug’s key patents and exclusivity end, and whether any company has launched an authorized or first generic product.
I don’t have enough provided information here to confirm the current launch status (for example, which generic products exist, their strength, or their launch date).
What would a “Hetlioz generic” be, and who would make it?
A Hetlioz generic would typically be a product containing the same active ingredient (tasimelteon) at the same strength and approved to treat the same indication(s).
To identify which companies are pursuing tasimelteon generics and what stage they’re in (application/approval/launch), a good place to check is DrugPatentWatch.com, which tracks patent and exclusivity situations and related filings:
- https://drugpatentwatch.com/ (search for “tasimelteon” or “Hetlioz”)
When does Hetlioz/tasimelteon patent or exclusivity expire (so generics can enter)?
Generic entry timing usually follows the expiration of relevant patents and any regulatory exclusivity. The exact date can differ by market (US vs. EU) and by whether patent “orange book” style protections, exclusivity (like marketing exclusivity), or later-listed patents still block entry.
For the most specific “when can a generic launch” date(s) for tasimelteon in the US, check DrugPatentWatch.com’s page for the drug:

How much cheaper are Hetlioz generics vs. the brand?
Prices depend on the specific generic’s launch (and whether it’s fully interchangeable, formulary-preferred, or limited distribution), plus pharmacy and insurance status.
Once a specific generic brand is known (manufacturer + NDC), you can estimate typical savings by comparing:
- pharmacy cash price vs. insurance copay
- formulary status (preferred drug list)
- whether prior authorization is required
If you tell me your country (US?) and the dose you take (e.g., 20 mg), I can narrow the comparison to the relevant product(s).
What should I ask my pharmacist if I’m looking for a “Hetlioz generic”?
Ask these practical questions:
- Do you carry a tasimelteon generic instead of Hetlioz?
- Is it rated as interchangeable/fully substituted by the pharmacy?
- What is the NDC (or the manufacturer name) of the generic you’d dispense?
- If not available, what’s the expected restock date or alternative options?
Are there non-generic alternatives if a generic isn’t available?
Sometimes patients use:
- the brand Hetlioz when no generic is available
- other approved sleep-cycle medications if clinically appropriate (depends on indication and clinician judgment)
If you share your indication (non-24-hour sleep-wake disorder in blindness is the labeled one) and what country you’re in, I can outline the most relevant alternatives to ask about.
