some antidepressants are used for conditions other than depression. for example bupropion (wellbutrin) is used for smoking cessation in non-depressed patients. however i want to make the point that all antidepressant medications require a prescription. no one should take an antidepressant medication without being evaluated by a physician. antidepressant medications carry the risk of side effects and the choice of antidepressant depends on a patient's medical history and other factors. antidepressants also may interact with other medications. that's why it's imperative that anyone taking an antidepressant be thoroughly evaluated by a qualified professional. so to answer your question: yes taking an antidepressant unnecessarily can potentially cause harm to the patient. please don't do it. hope this helps!
can you take an antidepressant without being depressed? can it cause harm?
