Abstract
We experienced a clinical case of a patient with psychotic depression who ingested the residual saponated cresol solution from a 500ml bottle of cresol, a disinfectant, with the intention of committing suicide. Through this experience, we felt it neccessary to investigate the present commercial situation of cresol for domestic use, and to come up with some safty measares.
All the 128 drugstores and pharmacies in four cities located in the Tohno area of Gifu Pref. (Mizunami, Toki, Tajimi and Ena) were queried by telephone about the sale and stock of cresol.
Almost 80% of the drugstores in these four cities, excluding pharmacies, were found to deal in saponated cresol solutions. They carried a little more than two 500ml bottles of cresol on average. This volume exceeds an estimated adult lethal dose of 250ml.
Although it is unlikely that an ordinary household will use the whole of 500ml bottle of the disinfectant at a time, the residual saponated cresol solution could increase the risk of accidental cresol poisoning at home.
So, it would be desirable not to sell 500ml bottles in ordinary drugstores. Furthermore, before selling a bottle of cresol, the pharmacists, who have a specialized knowledge about it, should kindly explain to the user about its toxicity and usage.
