Take Haloperidol exactly as directed by your doctor. Do not take more or less than instructed by your doctor.
You may need to take Haloperidol for some time before the full benefits can be felt. Do not be discouraged if you do not feel better soon after taking the medicine. Haloperidol must be taken regularly for it to work well.
