Mirtazapine is a tetracyclic antidepressant in the NaSSA class. It has a similar efficacy to SSRIs and TCAs, and it may be a better option for certain populations.

The drug may have some efficacy for other conditions like PTSD, anxiety, panic disorder, insomnia, and OCD. More research is needed in those areas.

Unlike some antidepressants, mirtazapine usually doesn’t cause sexual dysfunction and it doesn’t impair sleep. It often increases sleep, reduces sleep latency, and boosts slow-wave sleep.

Some recreational effects like euphoria, CEVs, enhancement of cannabis, and dream enhancement have been reported at certain doses. It’s not clear how reliable those effects are.
