Somatic symptoms in depression and antidepressants.

Somatic side effects of antidepressant medications and of depression and anxiety were quantified in depressed patients before and after 4 weeks of treatment with amitriptyline (N = 11), or desipramine (N = 12). The entire group showed significant posttreatment decreases in depression. Side-effect symptoms were significantly reduced after treatment in the amitriptyline group; less reduction was seen in the desipramine group. Significant correlations were demonstrated between levels of anxiety and side effect symptoms both before and after treatment. The reduction in side effect symptoms in the amitriptyline group can be explained by the drug's anxiolytic property. Our findings suggest that symptoms resembling antidepressant side effects seen in medicated depressed patients are influenced by the patient's clinical condition more than by the anticholinergic activity of moderate dosages of the antidepressant.
