How to use
The dosage is based on your medical condition, lab tests, and response to treatment. Your doctor may direct you to take a low dose at first, gradually increasing the dose to lower the chance of side effects such as shaking (tremors).
Do not take this drug more often or increase the dose. Your symptoms will not improve any faster, and the risk for heart rhythm problems will be increased. Follow your doctor's directions carefully.
Your doctor may order an electrocardiogram (EKG) and laboratory tests before you start this medication. These tests are to find out whether you are at risk for heart rhythm problems from pimozide. Keep all medical/lab appointments.
Other drugs, such as stimulant medications (such as methylphenidate, dextroamphetamine), may occasionally worsen tics. Before deciding to start pimozide, your doctor may try to reduce your tics by lowering the stimulant dose. Consult your doctor for more details.
Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor instructs you otherwise. Grapefruit can increase the amount of this medication in your bloodstream. Consult your doctor or pharmacist for more details.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Do not stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.
Tell your doctor if your condition persists or worsens.
