Clinical Significance
Subsequent to removal of patient from bromide therapy, the bromide is excreted, along with chloride, in essentially the same proportion in which they are present in the plasma. Thus, serum bromide concentration decreases slowly with a half-life of 12-15 days, unless special effort is made to increase bromide excretion rate by increasing chloride intake.
