Remeron (Mirtazapine)

Remeron is one brand name for mirtazapine, an antidepressant and alpha-2 antagonist. It is a tetracyclic antidepressant and is different from selective serotonin reuptake inhibitors (SSRIs) or tricyclic antidepressants (TCAs). This drug blocks specific alpha-2 receptors that subsequently increase norepinephrine and serotonin neurons in the brain. It also blocks a specific histamine receptor.

Remeron (Mirtazapine) Depression Treatment

Why is this drug prescribed?
Remeron is FDA-labeled in adults for major depressive disorder. There is also some evidence that favors the usage for anxiety, dysthymia, obsessive-compulsive disorder, and panic disorder in adults.

Remeron is used to treat major depression. When taken to relieve depression, its effects are usually felt within one to four weeks. The usual adult dose is between 15 and 45 mg/day.

Remeron is being used experimentally to treat children with ADHD, autism, and Asperger Syndrome, but its effectiveness for these diagnoses is not clearly established.
At lower doses, Remeron has been associated with increased hypnotic effects and thus has been used for insomnia.

How much of this drug is typically used?
Tablet: 15 mg, 30 mg, 45 mg
Tablet, orally disintegrating: 15 mg, 30 mg, 45 mg
