Dezypramina i Olanzapina + fluoksetyna: interakcja

Anyone considering the use of NORPRAMIN or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need.

Concomitant use of Monoamine Oxidase Inhibitors (MAOIs) and serotonergic drugs may potentially cause life threatening adverse events ( see CONTRAINDICATIONS , WARNINGS , and DOSAGE AND ADMINISTRATION ).

Nevertheless, caution is indicated in the co-administration of TCAs with any of the SSRIs and also in switching from one class to the other.

While all the SSRIs, e.g., fluoxetine, sertraline, paroxetine, inhibit P450 2D6, they may vary in the extent of inhibition.

Of particular importance, sufficient time must elapse before initiating TCA treatment in a patient being withdrawn from fluoxetine, given the long half-life of the parent and active metabolite (at least 5 weeks may be necessary).

If concomitant use of olanzapine and fluoxetine capsules with other serotonergic drugs is clinically warranted, patients should be made aware of a potential increased risk for serotonin syndrome, particularly during treatment initiation and dose increases ( 5.6 )

If concomitant use of olanzapine and fluoxetine capsules with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

If serotonin syndrome occurs, consider discontinuation of olanzapine and fluoxetine capsules and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.6 )] .

In 2 fluoxetine studies, previously stable plasma levels of imipramine and desipramine have increased >2- to 10-fold when fluoxetine has been administered in combination.

Anticholinergic (antimuscarinic) Effects : Use with caution with other anticholinergic drugs and in patients with urinary retention, prostatic hypertrophy, constipation, history of paralytic ileus or related conditions ( 5.21 )
