the most common withdrawal symptoms include: sleep disturbances, dizziness, nervous -
ness, dry mouth, anxiety, nausea, headache, sweating, and sexual problems. Duloxetine 
(Cymbalta) is another recently introduced SNRI that has been shown to be useful for 
depression and some forms of anxiety. However, with the exception of published case 
studies (Crippa et al. 2007), this drug has not yet been studied for social anxiety, and it 
is too early to recommend it for this problem.
Noradrenergic/Speciﬁc Serotonergic Antidepressants 
(NaSSAs)
Currently, the only NaSSA available is a drug called mirtazapine (Remeron). Like 
the SNRIs, mirtazapine works by affecting levels of both norepinephrine and sero -
tonin. This drug is newer than the other antidepressants discussed so far. Nevertheless, 
some initial studies suggest that mirtazapine is an effective treatment for social anxiety 
disorder (Muehlbacher et al. 2005; Van Veen, Van Vliet, and Westenberg 2002). The 
most common side effects of mirtazapine include sleepiness, weight gain, dry mouth, 
 constipation, and blurred vision.
