Maintenance of the Blind: For outpatients, study medication will be dispensed on a biweekly basis. They will be given two extra days of medication in case of a missed appointment. Inpatient subjects will receive their study medication daily from either the Spring Grove Hospital Center TRU or the Perry Point VAMHC central pharmacy. An unblinded pharmacist at each site will dispense all study medications. The blind will be broken only if a medical emergency requires this information. If this occurs, the participant will be withdrawn from the study.
