Trazodone is an antidepressant, but under 150 mg it doesn't really work as one as there is not enough chemical in it to stimulate serotonin which is why it's often paired with an SSRI for people with sleep and/or anxiety/depression issues. It contains an antihistamine which causes sedation - think of it as Benadryl on steroids. Physically speaking, there shouldn't be the need to withdraw from it from a physical standpoint, but there is the psychological effect of it which may require tapering in some cases; I quit cold turkey on it from 125 mg nightly after a few months a couple of years ago and was fine. Mirtazapine on the other hand at 7.5 mg+ does act as an antidepressant and should be weaned off.
Interestingly and paradoxically enough, with Trazodone and Mirtazapine at very high doseages they are LESS sedating. Trazodone was prescribed at 200-300 mg for depression in the past, but few doctors prescribe it for that anymore.
You could always try a low dose Doxepin for sleep.
However, one thing nice about Traz is the short half-life and less grogginess during the day compared to Mirtazapine and Doxepin.
