Promazine (brand name Sparine among others), is used as a short-term add-on treatment for psychomotor agitation. Its approved uses in people is limited, but is used as a tranquilizer in veterinary medicine. It has weak antipsychotic effects but is generally not used to treat psychoses.

It acts similar to chlorpromazine and causes sedation. It has predominantly anticholinergic side effects, though extrapyramidal side effects are not uncommon. It belongs to the typical antipsychotic and phenothiazine class of drugs.

Promazine was approved for medical use in the United States in the 1950s, although it is no longer commercially available there.
