The effect of inositol supplements on the psoriasis of patients taking lithium: a randomized, placebo‐controlled trial

Background  Lithium carbonate is the most widely used long‐term treatment for bipolar affective disorders, but its ability to trigger and exacerbate psoriasis can become a major problem in patients for whom lithium is the only treatment option. Inositol depletion underlies the action of lithium in bipolar affective disorders and there are good theoretical reasons why the use of inositol supplements might be expected to help this group of patients.
