Haloperidol belongs to a group of medications called "typical" or (first-generation) antipsychotic medications. It is not entirely known precisely how haloperidol works. However, it is known that haloperidol blocks or lessens the effects of dopamine, a chemical in the brain. Dopamine may be elevated in people with schizophrenia or other psychotic or behavior disorders.
The following are some general considerations for when and how to take haloperidol:
Haloperidol comes in tablet form. It is usually taken by mouth two or three times a day.
It does not matter if you take haloperidol with or without food. If haloperidol bothers your stomach, try taking it with food.
A liquid form of haloperidol is available for those who have difficulty swallowing tablets.
Haloperidol is also available in injectable forms, including a short-acting form (given several times per day) and a long-acting form (given just once a month).
Haloperidol should be taken at the same time(s) each day to maintain even levels of the drug in your blood.
For haloperidol to work properly, it must be taken as prescribed. Haloperidol will not work if you stop taking it.
