Final answer:
Blood pressure medications, classes of antipsychotics, and antidepressants such as SSRIs can cause nipple discharge, while other psychiatric treatments usually do not.
Step-by-step explanation:
Medications that can cause nipple discharge include a variety of classes such as blood pressure medication, certain classes of antipsychotics, and some antidepressants, specifically those known as selective serotonin reuptake inhibitors (SSRIs). Other treatments for psychiatric conditions, such as psychotherapy, electroconvulsive therapy, and deep-brain stimulation, do not typically cause nipple discharge. It's important to note that nipple discharge can also be a symptom of other underlying conditions, and anyone experiencing this should consult their healthcare provider.
