Clomipramine may interact with a number of different medications, including the monoamine oxidase inhibitors which include isocarboxazid, moclobemide, phenelzine, selegiline and tranylcypromine, antiarrhythmic agents, diuretics, the selective serotonin reuptake inhibitors and serotonergic agents such as triptans, other tricyclic antidepressants, tramadol, etc. Its use is also advised against in those concurrently on CYP2D6 inhibitors due the potential for increased plasma levels of clomipramine and the resulting potential for CNS and cardiotoxicity. Clomipramine use during pregnancy is associated with congenital heart defects in the newborn. It is also associated with reversible withdrawal effects in the newborn. Clomipramine is also distributed in breast milk and hence nursing while taking clomipramine is advised against.
