Atypical antidepressant (NaSSA)
What to do if you miss a dose of Mirtazapine
Missing a dose of Mirtazapine (Mirtazapine) is common — most people will skip a dose at some point during a course. The right action depends on how long since the missed dose and whether Mirtazapine is taken event-driven or daily at 7.5mg, 15mg, 30mg, 45mg. The wrong action — doubling up — is not recommended.
For daily Mirtazapine
If Mirtazapine is taken daily for a chronic condition, take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. In that case skip the missed dose and continue normally. According to the prescribing information for Mirtazapine, two doses should never be taken close together to "make up" for a miss.
For event-driven Mirtazapine
If Mirtazapine is used as needed (not on a fixed schedule), there is no "missed dose" in the conventional sense — simply take the planned dose when needed and observe the recommended gap before re-dosing. Mirtazapine antagonises presynaptic α2-adrenergic autoreceptors and heteroreceptors, increasing noradrenaline and serotonin release.
Frequently asked questions
Should I double the dose if I missed Mirtazapine? ▾
No. Doubling doses of Mirtazapine to compensate is not recommended at any 7.5mg, 15mg, 30mg, 45mg strength and increases the risk of side effects without improving efficacy. Take the next scheduled dose normally.
How many missed doses are too many? ▾
Occasional missed doses of Mirtazapine are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Atypical antidepressant (NaSSA), consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
