1996	Castañeda et al.	Nefazodone	Report of three cases in which NFZ had been abruptly substituted for FLX, PRX and VFX, "with the emergence of anxiety, dysphoria, affective lability, agitation, restlessness, confusion and somatic complaints such as headaches, tremors and nausea", together with intense craving for opiates or cocaine in three "otherwise stably abstinent patients".
1998	Benazzi	Nefazodone	Letter: thought to be the first published report (in the English- language literature) of nefazodone withdrawal problems. Patient was 27-year old male, with diagnosed "dysthymic disorder and social phobia". After three months on clomipramine and alprazolam, NFZ 250mg/day was added. One month later NFZ was abruptly withdrawn. Patient experienced similar withdrawal symptoms to those he had previous had when coming off  VFX. Symptoms spontaneous resolved after three days.
1999	Kotlyar et al	Nefazodone	This case report concerns a healthy 28-year old male volunteer, given up to 400mg/day NFZ (the usual therapeutic dose) for nine days. Following abrupt discontinuation, subject reported "electric shock-like symptoms, dizziness, and nausea". Symptoms began to subside 72-hours after stopping and ceased shortly thereafter.
1999	Lauber	Nefazodone	After four weeks of treatment at the usual therapeutic dose (400mg/day), this young woman patient abruptly stopped treatment and 48 hours later experienced "nausea, vomiting, fatigue, headache, myalgia, sweating, restlessness, dizziness, sleeping disturbances with vivid nightmares, severely depressed mood, emotional lability and anxiety" plus "brief moments of disorientation and shock-like sensations". Four days later treatment was restarted and symptoms promptly resolved. Author comments that, in view of the relatively short half-life of NFZ, it seemed surprising that the onset of the withdrawal syndrome occurred only 48 hours after discontinuation.
1999	Rajagopalan and Little	Nefazodone	Case report: 41 year old patient took nefazodone 100mg/day for three weeks, but her conditioned worsened and it was decided to reduce and then stop the NFZ (after 3 days on 50mg/day). Severe withdrawal symptoms began two days off drug and lasted another week ... "she became frightened by what she described as the worst feeling throughout. Although she found the experience difficult to describe, she reported that her head felt itchy inside, had racing thoughts, felt anxious and hyped up to the point that she wanted to hit her head on the wall in order to make it stop ..."
	Yapp et al	Nefazodone	Case report involving admission of breast-fed premature baby found "drowsy, lethargic, unable to maintain normal body temperature and feeding poorly". Authors report their data "suggest a putative association between maternal nefazodone ingestion and adverse effects" in this infant.  The measured amount of drug exposure would normally be considered safe in a full-term infant; however, adverse effects in the infant resolved when breastfeeding was stopped.
