Case 2
A 23 year old Malay woman diagnosed as case of schizo affective disorder
depressive subtype with current minimal psychosis was prescribed
quetiapine 25 mg/day and increased to 50 mg daily. At the dose of
quetiapine 50 mg/day she developed SRED. The quetiapine was stopped and
substituted with aripiprazole 5 mg with no further episodes. Her
concurrent medication were desvenlafaxine 100 mg daily and lithium 300
mg ON. During the 5 months that the patient experienced SRED she put on
5 kg. Physical examination was unremarkable. It was the same treating
doctor for both cases and hence the side effect in the second case was
identified earlier and a more appropriate drug was administered. Unlike
in the first case the second patient did not continue to have SRED as
aripirazole and not olanzapine was used as the substitute drug.
Both cases have insignificant medical history, with no history of sleep
walking, seizure, childhood or family history of parasomnia or alcohol
abuse. Both patients were unaware of their actions of eating while
asleep until informed by family.
