How long has she been taking Celexa? Dose?
How long has her provider been mixing it with Nexium and an NSAID? Does she have a history of diabetes?
I'd like to withhold all three of her meds, however, she is at risk for discontinuation syndrome with stopping the citalopram cold-turkey. She needs to taper off the Celexa as quickly and safely as possible, but I'd withhold the other two meds indefinitely.
She needs a BGL, CBC, CMP, liver enzymes, and renal workup. I want to know her K+ and Na levels. She also needs a 12-lead, I want to see her QT interval.
As a Native myself, I'm certain I know what the cultural shortfall in her treatment has been. I believe dementia is at the bottom of the list of possible medical diagnosis right now.
