Take this medication by mouth with or without food as directed by your doctor, usually once a day in the morning when you first start treatment. Your doctor may gradually increase your dose to 2 or 3 times a day over several weeks. A slow increase in your dose will help your doctor find the best dose for you while keeping side effects as low as possible.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.

If you stop taking this drug for several days, then start taking it again, you may need to slowly increase your dose until you reach the regular dose you had been taking. Follow your doctor's directions on how to restart treatment.

Tell your doctor if your uncontrolled movements do not improve or if they worsen.
