This is a decision you and your doctor will make. Tell your doctor if you have ever had any unusual or allergic reaction to pimozide, haloperidol, or other medicines used to treat mental illness. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes. Studies in rats and rabbits given more than the highest recommended human dose of pimozide have shown fewer pregnancies, slowed development of the fetus, and toxic effects in the mother and fetus. It is not known whether pimozide passes into breast milk.
Children are especially sensitive to the effects of pimozide.
This may increase the chance of side effects during treatment. Pimozide usually is not used in children for any condition other than Tourette's syndrome. Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. The presence of other medical problems may affect the use of pimozide.
