Acute Bromide Intoxication in a Patient with Preserved Renal …

Although bromide ions are excreted from the kidneys with a long half-life of 10 to 14 days, the half-life can be reduced to one-quarter by saline diuresis alone and to a few hours by hemodialysis therapy . In the current case, hemodialysis was not introduced because the symptoms smoothly improved by hydration.
