Atypical antidepressant (NaSSA)
What to do if Mirtazapine is in shortage
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Mirtazapine (Mirtazapine) may become temporarily unavailable in some pharmacies or countries. For chronic users at 7.5mg, 15mg, 30mg, 45mg, knowing how to handle a shortage prevents unnecessary treatment interruption.
How shortages work for Mirtazapine
When Mirtazapine is in shortage, the pharmacist usually has several options: dispense an authorised generic of Mirtazapine, source from a different manufacturer of the same active ingredient, suggest a different formulation (e.g. liquid, dispersible) or, in extended shortages, ask the prescriber to consider an alternative Atypical antidepressant (NaSSA) agent. Mirtazapine antagonises presynaptic α2-adrenergic autoreceptors and heteroreceptors, increasing noradrenaline and serotonin release.
Practical steps
According to general pharmacy practice, the first step in a Mirtazapine shortage is to ask the pharmacist about authorised generic availability — most shortages affect a single brand or strength, not the entire supply of Mirtazapine at 7.5mg, 15mg, 30mg, 45mg. The prescriber should be informed if the pharmacist needs to substitute or change formulation. Stockpiling or buying extra outside regulated channels is not the right response.
Frequently asked questions
What do I do if my pharmacy doesn't have Mirtazapine? ▾
Ask the pharmacist whether an authorised generic of Mirtazapine is available — usually yes — or whether another pharmacy in the area has stock of Mirtazapine at 7.5mg, 15mg, 30mg, 45mg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Mirtazapine come back in stock? ▾
Most shortages are resolved within weeks to months as manufacturing or supply issues are fixed. Until then, the authorised generic of Mirtazapine is the standard alternative and is clinically equivalent to Mirtazapine at the same 7.5mg, 15mg, 30mg, 45mg strength.
