Psychiatric shades of grey: mirtazapine-induced hair discoloration and hair loss.

UNLABELLED: Introduction Mirtazapine is indicated in the treatment of major depressive disorder particularly in selective serotonin re-uptake inhibitors resistance. Its effect on hair loss is rare with no previous documented effect on hair colour.

METHOD: Review of relevant literature and description of a case report of a 54-year-old male patient who developed alopecia and hair discoloration after initiation of mirtazapine treatment.

RESULTS: Upon cessation of mirtazapine treatment full restoration of hair colour and regrowth of hair was attained within 10 weeks. Discussion There was clear temporal relationship between experiencing hair loss and commencing mirtazapine treatment. No other more likely medical reason to explain such experience was established. A noticeable restoration of the hair colour occurred following mirtazapine cessation.

CONCLUSION: Mirtazapine is associated with hair discoloration and hair loss. The possibility of such distressing adverse effects needs to be conveyed to patients by clinicians and to be further explored by researchers.
