Dr. Lucy Puryear, an expert witness hired by Yates's defense team, countered their contention regarding the administration of her antidepressants, saying the dosages prescribed by Dr. Saeed are not uncommon in practice and had nothing at all to do with her re-emergent psychosis. She suggested rather that her psychosis returned as a result of the Haldol having been discontinued by her doctor two weeks earlier. The oral form of haloperidol (Haldol) takes 4–6 days after discontinuation to reach a terminal plasma level of under 1.5%—a medical standard for "complete" elimination of a drug from the body.
