Mirtazapine inhibits anxiety.
Mirtazapine in combination with a selective serotonin reuptake inhibitor, serotoninnorepinephrine reuptake inhibitor, or tricyclic antidepressant as an augmentation strategy is considered to be relatively safe and is often employed therapeutically but caution should be given when combined with fluvoxamine
 Mirtazapine has been shown to lower drug seeking behaviour (more specifically to methamphetamine) in various human and animal studies
