Discontinuation Syndrome
Abrupt interruption of sertraline treatment may result in withdrawal or discontinuation syndrome. This syndrome occurred in 60% of the remitted depressed patients taking sertraline in a blind discontinuation study, as compared to 14% of patients on fluoxetine and 66% of patients on paroxetine. During the 5–8-day period when sertraline was temporarily replaced by placebo, the most frequent symptoms (reported by more than a quarter of patients) were irritability, agitation, dizziness, headache, nervousness, crying, emotional lability, bad dreams and anger. Around a third experienced mood worsening to the level generally associated with a major depressive episode. In a double-blind study of remitted panic disorder patients, abrupt discontinuation of sertraline treatment resulted in insomnia and dizziness (both 16–17% vs. 4% for continuing treatment), although headache, depression and malaise did not increase significantly. In another double-blind study of recovered panic disorder patients, the withdrawal syndrome was completely avoided when sertraline was gradually discontinued over three weeks, while patients stopping paroxetine treatment still suffered from it. There is at least one report of orthostatic hypotension as a result of sertraline withdrawal.

Famous quotes containing the word syndrome:
“Women are taught that their main goal in life is to serve others—first men, and later, children. This prescription leads to enormous problems, for it is supposed to be carried out as if women did not have needs of their own, as if one could serve others without simultaneously attending to one’s own interests and desires. Carried to its “perfection,” it produces the martyr syndrome or the smothering wife and mother.”
—Jean Baker Miller (20th century)
