Step-by-step explanation:

Of the choices provided, the answer to the question is Urinary retention, which can be an emergency. Most common side effects of antidepressants like loss of interest, gastric upset, or sedation are generally not emergencies but could warrant a call to the doctor for advice.

It is essential to monitor and address any physical symptoms that may arise during antidepressant therapy.
