Trazodone's own FDA labeling lists withdrawal symptoms — including anxiety, agitation, and sleep problems — and specifically advises against stopping without talking to a healthcare provider first. A typical taper involves gradually reducing the dose over a period of days to weeks, rather than stopping abruptly.
The specific taper schedule depends on your current dose, how long you've been taking it, and why it was prescribed — there is no single universal taper plan. If you experience withdrawal-type symptoms during a taper, contact your prescriber rather than stopping the taper plan or reverting to your original dose on your own.
