Is haldol a controlled substance?

Yes. Haldol (haloperidol) is generally considered a controlled substance in the U.S.—it’s regulated under the federal Controlled Substances Act (commonly listed as Schedule H, which is a prescription-only classification for certain drugs, including haloperidol).

That said, the exact scheduling can vary by country/state and can depend on the specific formulation.

If you tell me what country (and state/province, if applicable) you’re in, I can give the most accurate answer for your location.
