It is thought that mirtazapine's actions on other types of receptors cause some of the side effects of mirtazapine, such as drowsiness or low blood pressure. Certain receptors decrease the levels of serotonin and norepinephrine released by the nerves. Mirtazapine blocks these inhibitory receptors, causing more serotonin and norepinephrine to be released. This may help to relieve symptoms of depression. Mirtazapine is not approved for use in childhood depression. Two studies on children and adolecents did not show that mirtazapine was effective for depression in these age groups.
