“…A systematic review of randomized controlled trials, documented the most common side effects of pregabalin including dizziness, vertigo, incoordination, balance disorder, ataxia, diplopia, blurred vision, tremor, drowsiness, confusion, disturbance of attention, euphoria, disorganized thinking and fatigue [8]. Adverse reactions occur more often at high doses and pregabalin has been associated with psychosis, hallucinations and other neuropsychiatric symptoms when titrated rapidly [9,10]. In contrast to these studies which suggest that visual hallucinations from pregabalin are mainly attributed to rapid titration, our study indicates that this side effect may be dose depended and can appear in cases of slow titration as well, as happened in our case.…”
