For some people, the risks associated with stopping the medication are higher than those associated with continuing to take it. If a person is pregnant and wishes to continue or begin taking antidepressants, they should speak with a doctor. Tiny amounts of some antidepressants can enter breast milk. However, the CDC states most antidepressants will have no effect on milk supply or the child's well-being.
