When did Dificid (fidaxomicin) go generic?

Dificid (fidaxomicin) did not go fully generic at the same time it was first available as a brand. In the U.S., generic entry depends on the timing of patent and exclusivity protections expiring for each formulation/strength.

Was a generic fidaxomicin available before “official” generic launch?

Sometimes patients and providers see “generic” products appear in parts of the market before a formal nationwide launch, or they may see authorized generics/marketed equivalents. The exact timeline for fidaxomicin depends on what specific product (strength/formulation) and what you count as “generic” (first FDA approval vs. pharmacy availability).

What’s the most reliable source for the exact generic-launch date?

What I need from you to give the exact date

If you tell me:
1) the country (U.S. vs. another market), and
2) whether you mean “first FDA-approved generic” or “first widely available in pharmacies,”
I can narrow to the exact date for that definition.
