Can generics enter right after the Abreva patent expires?

Even if a patent expires, market entry can still be affected by:
- Whether other listed patents still cover aspects of Abreva (for example, certain formulations or methods).
- Regulatory requirements for generic approvals (and whether any exclusivity periods still apply).

For Abreva, the practical entry question is best answered by comparing the set of patents/exclusivities remaining at the time to the generic or “lower-cost alternative” filings and approvals shown in the same patent listings. DrugPatentWatch.com – Abreva (docosanol)
