**3.2.2.3 Antidepressants**

All tricyclic antidepressants have an anticholinergic effect, with amitryptiline having the strongest and nortriptyline the weakest (White et al., 2007). Delirium has been reported to develope after abrupt discontinuation of fluoxetine (Blum et al., 2008) and with concominant use of fluoxetine and lamotrigine (Chistyakova & Amos, 2008). In addition, concomitant use of low-dose bupropion sustained release and fluoxetine has been reported to be associated with delirium (Chan et al., 2006).
