[top]Introduction to Mirtazapine


Mirtazapine is a tetracyclic antidepressant used primarily in the treatment of depression. Mirtazapine is one of the few noradrenergic and specific serotonergic antidepressants (NaSSAs). It has been demonstrated to have far fewer side effects than most other typical anti-depressants on the market.

Mirtazapine is unusual for an anti depressant as it has effects that are apparent instantly. The instant effects are sedating, which can help people with sleep, whereas the long term anti depressant/anxiety effects will not become apparent until amounts in the body have built up to a sufficient level over months of use. It takes 5 days for a given dosage to build in the bloodstream to stable levels.


[top]Using Mirtazapine

The usual starting dose of mirtazapine is 15 mg, given at bed-time. This can be increased to 45mg over time, but close doctor supervision is indicated for an increase above that amount.

[top]Ways of Administration

Mirtazapine is normally supplied in oral tablets.
