In Chula Vista's Eastlake area, psychiatric nurse practitioner Marilou M. Cabusao, MSN, PMHNP provides medication management and psychiatric evaluations through LifeStance Health's Boswell Road clinic in the 91914 corridor. Her prescribing expertise covers anxiety, depression, bipolar disorder, OCD, psychosis, and PTSD, with laboratory monitoring for psychotropic medication compliance and metabolic side effects coordinated through diagnostic providers including Fastest Labs of Chula Vista for serum-level draws, metabolic panels, and substance-screening protocols. Affiliated with Paradise Valley Hospital and trained in Transcranial Magnetic Stimulation, she serves adults and seniors with particular depth in geriatric psychiatry, veteran-specific behavioral health, and LGBTQ+-affirming care. Her medication-management workflows integrate pharmacogenetic testing data to guide SSRI, SNRI, and antipsychotic selection, with prescription coordination routed through independent dispensaries such as Chula Vista Pharmacy for fill tracking and drug-interaction surveillance. Clozapine protocols for treatment-resistant psychotic disorders require mandatory absolute neutrophil count monitoring at 7-day, 14-day, and 28-day intervals through the Clozapine REMS Program to detect early agranulocytosis before white-cell counts drop below clinical-safety thresholds.
