- From the text:
“To promote adherence, educate pateints and families about the nature of BPD and the importance of taking lithium as prescribed. Encourage family members to oversee lithium use, and advise them to urge the patient to visit the prescriber or a psychiatric clinic if a pattern of nonadherence develops.”
