Stopping Antidepressants: Withdrawal and Tapering in Japan
Don't stop an antidepressant suddenly on your own. Japanese drug labels are explicit about this: reduce gradually, over weeks or months, while watching how you respond. Stopping is a normal part of treatment, and many people do come off eventually; it simply goes far better as a planned taper than as a sudden stop.
What happens if you stop an antidepressant suddenly?
Discontinuation symptoms can appear. Paroxetine is the clearest example, and the one this article will refer to most, because its Japanese label describes stopping in unusual detail: it lists dizziness, electric-shock-like sensations, sleep problems including nightmares, anxiety, nausea, and headache among the symptoms reported after stopping. The escitalopram label carries a similar, shorter list. Not everyone gets these; the labels describe what can happen, not what will.
The illness itself can also come back. The medicine was treating something, and relapse of depression or anxiety is a real risk when treatment ends without a plan.
These two problems are easy to confuse with each other. Anxiety and broken sleep appear on both lists, so without your doctor involved it's genuinely hard to tell "my body is adjusting" from "my depression is returning," and the right responses differ.
Is this withdrawal? Are antidepressants addictive?
No. Discontinuation symptoms are not addiction. The paroxetine label states this directly: based on the information so far, these symptoms are not considered the result of drug dependence. SSRI labels describe discontinuation symptoms but carry no dependence warning. Benzodiazepines are the contrast case: their labels do warn of dependence, and stopping them is a different, higher-stakes process; if that's what you want to stop, see our benzodiazepine guide. For antidepressants, the point is that discontinuation symptoms are possible without dependence, which is exactly why the labels still require a planned taper.
How does tapering work in practice in Japan?
Tapering in Japan runs on the visit cycle. A limited refill prescription system for stable, unchanged prescriptions was introduced in Japan in 2022, but a taper involves changing the dose at each step, so it runs on regular visits: each prescription covers a set number of days, and the next step down means seeing your doctor again. Routine psychiatric follow-ups typically run every two to four weeks, and a taper maps naturally onto that cycle: the dose steps down at one visit, and you review how it went at the next.
Three things make the conversation easier:
- Say the goal out loud. "I'd like to work toward stopping this medication" is a normal request that psychiatrists hear regularly, not a challenge to the doctor.
- Ask what the first step down would look like: also which symptoms would mean the pace is too fast.
- Agree in advance on what to do if symptoms appear between visits: whether to call, wait, or return to the previous dose.
If a step down turns out to be intolerable, the paroxetine label itself describes the standard move: go back to the previous dose, then reduce more slowly. That is a standard adjustment, not a failure, and it is a decision to make with your prescriber rather than alone.
How long does coming off take?
There is no fixed timetable. For paroxetine, the label's instruction is to reduce gradually over weeks or months depending on how the patient is doing. In practice the length depends on which medicine you take, the dose, how long you've been on it, and how you respond to each reduction. A taper that stretches longer than you hoped is common and is not a sign that anything has gone wrong. What matters is that each step is one you tolerate, confirmed at a follow-up visit, with the option to pause or step back built in.
