These are widely used in states of agitation, tension and aggression, ad are perhaps more properly called psycho - correctives. They have a varied range of qualities, and some types have been developed that require an injection every two to three weeks.

As with many such preparations, these can cause drowsiness, dizziness, constipatioin, headache, lowered blood pressure (hypotension) and Parkinsonism. Rarely, they produce a reaction in which the tongue protrudes, the eyes roll, the face is distorted. This is alarming to the unfamiliar but is quickly corrected by anti - Parkinsonian agents.
