Treatment of Painful Muscle Cramp Due to Heat Injury Using Shakuyakukanzoto

Abstract

We treated 5 patients with painful muscle cramp due to heat injury using Shakuyakukanzoto. According to their severities, 4 patients were classified with 1 st degree and 1 patient with 3rd degree heat injury. Painful muscle cramps in 4 patients with 1st degree were cured through a single dose of Shakuyakukanzoto. On the other hand, painful muscle cramps in 1 patient with 3rd degree was managed for 4 days after administration of Shakuyakukanzoto. No Shakuyakukanzoto complications were observed in any patient, nor contribution to rhabdomyolysis in 3 patients. Shakuyakukanzoto may be useful to prevent acute kidney injury due to rhabdomyolysis by controlling painful muscle cramps in heat injury.
