When symptoms increase periodically during protracted withdrawal, physiological changes may be present, including dilated pupils as well as an increase in blood pressure and heart rate.

Clonidine's blood pressure lowering effects are due to stimulation of presynaptic α 2 autoreceptors in the CNS which suppress sympathetic outflow. Mirtazapine itself blocks these same α 2 autoreceptors, so the effect of adding mirtazapine to a patient stabilized on clonidine may precipitate withdrawal symptoms. [75]
