Risperdal generic risperidone patent?

Short answer: Risperidone (Risperdal) as the molecule is no longer under patent in most markets, and generic risperidone is widely available. However, there can be separate patents or exclusivities on certain formulations or delivery systems (for example, Risperdal Consta long-acting injectable or other specific tablet formats) that can affect generic versions for those products in some places.

If you want country-specific details, tell me which country you’re asking about (e.g., United States, a European country, etc.). I can look up the current status and give you:

- Whether the basic risperidone molecule is patented in that country
- Whether any brand-specific formulations have active patents or exclusivities
- The typical time frames you’d expect for generic entry

For a quick check yourself, you can look up:
- FDA Orange Book (US) – search “risperidone” and check the patents/exclusivities tab
- European patents databases or the EMA/European Orange Book equivalents for the EU

Want me to pull the current status for a specific country? If so, which one?
