What generic mirtazapine brands are available?
Mirtazapine is marketed in multiple generic “brand” names that vary by country and by the manufacturer licensed to sell the drug. In many places, the active ingredient stays the same (mirtazapine), while product names differ on the pharmacy shelf.
Because availability depends on your location, the fastest way to identify the exact generic brands you can buy is to search by:
- the drug strength (e.g., 7.5 mg, 15 mg, 30 mg, etc.)
- your country (or state/province)
- the label terms “mirtazapine” plus your local supplier/manufacturer
If you share your country (and any strength you’re prescribed), I can help narrow down which labeled generics are commonly sold there.
How do mirtazapine generic products differ if they’re all “mirtazapine”?
Even when products share the same active ingredient, differences that can matter for patients include:
- formulation (regular tablet vs. orally disintegrating/specific brand formulation where applicable)
- dosing strengths available
- excipients (inactive ingredients), which can matter for allergies or sensitivities
- manufacturer (which affects appearance, pill size, and sometimes how people tolerate it)
If you switch between generic brands and notice a change in how you feel, it’s often worth checking whether you changed formulation or tablet strength, not just the name on the box.
Are brand-name Remeron and generic mirtazapine interchangeable?
In general, generic mirtazapine is intended to be therapeutically equivalent to the branded product (for the same strength and formulation). Interchangeability is usually based on regulatory bioequivalence requirements, but small differences in inactive ingredients can still affect some patients.
If you’re currently stable on one mirtazapine product, ask your pharmacist whether the pharmacy is switching manufacturers and whether the formulation is identical.
What if my pharmacy gives me a different mirtazapine generic than the one I used before?
That can happen due to supply or contracting. Practical steps:
- verify the strength on the label
- ask if the manufacturer or formulation changed
- keep taking it as prescribed and contact your prescriber if you notice significant side effects or loss of benefit

What should you ask your pharmacist to find the right generic mirtazapine?
Ask:
- “Is this the same formulation as my previous mirtazapine?”
- “Did the manufacturer change?”
- “What strength and dosage form am I getting?”
- “Is it bioequivalent to the one I used before?”
If you tell me your country and the strength you take (e.g., 15 mg nightly), I can tailor the answer to the most likely generic brand names available where you are.
