Different anti-depressants need different taper strategies. You can taper off Clomipramine
over a period of 3-4 weeks. His symptoms may need monitoring during the taper. If needed, the taper period can be prolonged further. If you feel the aggressiveness at night is a bit too much to handle, you can think about continuing with 10mg for a week or so and then trying the taper again. Hope this helps.
