Is Stelazine still available in the US?

Excuse me, I was wondering if you could clarify something for me regarding the availability of Stelazine in the United States. I understand that this medication was previously prescribed for certain conditions, but I'm unsure if it's still widely accessible or if there have been any changes in its distribution or legal status. Could you please provide some insight into whether Stelazine is still available for patients in the US, and if so, under what circumstances or with any specific restrictions? Thank you for your time and assistance.
