In terms of medical management of the symptoms associated with Chromosome15q 11.2-13.1 Duplication Syndrome, families should be aware that individuals with chromosome15 duplications may tolerate medications differently and may be more sensitive to side effects for some classes of medications, such as the serotonin re-uptake inhibitor type medications (SSRI). Thus, these should be used with caution and any new medication should be instituted in a controlled setting, with slow titration of levels and with a clear endpoint as to what the expected outcome for treatment is.
