ZINC SALTS FOR THE TREATMENT OF OLFACTORY AND GUSTATORY SYMPTOMS IN PSYCHIATRIC-PATIENTS - A CASE SERIES

Background: Zinc salts have been used extensively in medical settings to treat disorders of gustatory and olfactory function. However, zinc supplements have not been tested in psychiatric patients with smell or taste symptoms. Method: The authors examined the effects of zinc supp lements on five consecutive patients with symptoms of abnormal taste a nd smell perception in the context of acute psychiatric illness or tre atment. Results: All five patients had complete or partial amelioratio n of these olfactory and gustatory symptoms after treatment with zinc sulfate or zinc gluconate, apparently independent of the improvement i n their underlying psychiatric disorder. Conclusion: We recommend trea ting unusual olfactory and gustatory symptoms with zinc salts, indepen dent of the treatment for the underlying psychiatric disorder.
