My adult son has just started antidepressants. He suffers from depression and is feeling a lot worse a few days in. I am worried about this as I know some antidepressants make people feel suicidal initially. i have had no reassurance or information myself and because my son is isolated and living at home, feel very anxious about him . What are the effects and how long are the adverse effects likely to last? They start with a C, have to check the label.
