A nurse is providing teaching to a client who has depressive disorder and a new prescription for doxepin. Which of the following instructions should the nurse include in the teaching?

A. Avoid over-the-counter magnesium when taking this medication: There is no specific contraindication between doxepin and magnesium supplements. However, clients should consult their healthcare provider before using any over-the-counter products. B. Eat a snack before going to bed: While this is not incorrect for some medications, it is not a primary teaching point for doxepin. The medication's primary side effect concerns are sedation and orthostatic hypotension, not hunger-related issues. C. Sit on the side of the bed for a few minutes before standing: Doxepin, a tricyclic antidepressant, can cause orthostatic hypotension, leading to dizziness when standing. Sitting on the side of the bed before standing helps reduce this risk by allowing the body to adjust to the change in position. D. Decrease the prescribed dose by half when mood improves: Clients should never adjust their prescribed medication dose without consulting their provider. Abruptly stopping or reducing the dose can cause withdrawal symptoms or a relapse of depressive symptoms.
