Mirtazapine Shortage Update: What Patients Need to Know in 2026

Reports of difficulty filling mirtazapine prescriptions have prompted many patients to ask: is there a real shortage? Here's the most up-to-date information available for 2026.

Current Mirtazapine Shortage Status (2026)

As of 2026, the U.S. Food and Drug Administration (FDA) has not listed mirtazapine on its official drug shortage database. Mirtazapine is a widely available generic drug manufactured by multiple companies, including Aurobindo, Zydus, Teva, and others. This multi-source generic status provides a buffer against the type of catastrophic shortages seen with single-source drugs.

That said, many patients experience genuine difficulty filling their mirtazapine prescription at their usual pharmacy. These are localized, temporary shortfalls — not a national shortage — but they are real and disruptive for the patients affected.

Why Are Some Pharmacies Out of Mirtazapine?

Several factors can cause a local pharmacy to be out of mirtazapine even when no national shortage exists:

Just-in-time inventory: Many chain pharmacies minimize inventory to reduce costs. A higher-than-expected week of mirtazapine fills can deplete stock.

Distributor disruptions: Mid-level drug distributors can have their own inventory gaps, even when manufacturers have product.

Rising off-label prescribing: Mirtazapine is increasingly prescribed off-label for insomnia, anxiety, and nausea, increasing overall demand.

Specific strength scarcity: The 7.5 mg tablet and orally disintegrating tablet (ODT) forms are stocked less frequently than the more common 15 mg and 30 mg regular tablets.

Historical Context: Has Mirtazapine Ever Been in Shortage?

Mirtazapine has not historically been listed on the FDA's official shortage database at a national level. Unlike medications such as Adderall or certain injectables that have experienced declared national shortages, mirtazapine's multi-manufacturer generic status has provided relatively stable supply at the national level. Local availability remains the variable that most often affects patients.

Which Mirtazapine Products Are Hardest to Find?

Based on patient reports, these products are most likely to be out of stock at any given pharmacy:

Mirtazapine 7.5 mg tablets: The lowest dose, often used in elderly patients or for sleep. Less commonly stocked.

Orally disintegrating tablets (ODT): Remeron SolTab and its generics are stocked less often than standard tablets.

Brand Remeron: The brand 45 mg tablet has been discontinued; brand Remeron in other doses may be harder to find than generic.

What Should Patients Do Right Now?

If you're having trouble finding mirtazapine, here are the most effective steps:

Don't wait until you run out — refill 7-10 days early.

Use medfinder to find which pharmacies near you have it in stock — this saves hours of calling.

Ask your prescriber about switching to a 90-day mail-order supply.

If your specific strength is out, ask your prescriber whether a different strength or formulation is clinically appropriate.

Don't Stop Mirtazapine Suddenly

Abruptly discontinuing mirtazapine can cause discontinuation syndrome — including severe rebound insomnia, anxiety, irritability, and worsening depression. If you're running low and can't find a refill, contact your prescriber the same day rather than stopping doses on your own. A prescriber can write a partial fill or help you bridge until your prescription can be filled.

medfinder calls local pharmacies on your behalf to check for mirtazapine availability and texts you the results. It's the fastest way to find which pharmacy near you has your prescription in stock without spending hours on hold.
