Mirtazipine can cause serotonin syndrome which is characterized by hyperactivity, muscle tremors, vocalization and behavior changes. This is more likely at high doses but has been reported to occur at typical doses as well. It is cleared through the kidneys so a dose reduction is typically recommended for cats with decreased kidney function. Megacolon should not be a concern.
