Suspected antidepressant-induced switch to mania in unipolar depression: a first-person narrative.

BACKGROUND

Antidepressant-induced switch to mania has not been thoroughly characterized in bipolar disorder and is even less well understood in unipolar depression.

METHOD AND

RESULTS

I describe, as a first-person narrative, my own experience of psychotic mania, which was suspected to have been induced by the tricyclic antidepressant, dosulepin. I have had a 16-year history of depression and was receiving sertraline 50 mg od when I was prescribed, off licence, dosulepin 25 mg 1-2 nocte for insomnia. Within days, I developed mild hypomanic symptoms and returned to my GP, who discontinued dosulepin but continued treatment with sertraline. I was also referred for psychiatric assessment. Two months later, I was detained under Section II of the Mental Health Act 1983 and admitted to hospital with psychotic manic symptoms.

CONCLUSION

More understanding of antidepressant-induced switch to mania is needed in unipolar depression. My case study highlights the need for prompt specialist care for patients with depression reporting even mild, sub-threshold symptoms of mania.
