Application: Thiamine hydrochloride is effective for the treatment of thiamine deficiency or beriberi whether of the dry (major symptoms related to the nervous systom) or wet (major symptoms related to the cardiovascular system)variety.Thiamine hydrochloride should be used where rapid restoration of thiamine is necessary,as in Wernicks encephalopathy,infantile beriberi with acute collapse,cardiovascular diease due to thiamine deficiency,or neuritis of pregnancy if vomiting is severe.It is also indicated when giving IV dextrose to individuals with marginal thiamine status to avoid precipitation of heart failure.
