Oral dehydroemetine dihydrochloride (+/-) (Mebadin) was found useful both as a tissue and contact amoebicide. It is much less toxic and more active than emetine and can be given in larger doses and for longer periods with safety. Owing to the quick excretion, repeat courses can be given at short intervals, as necessary, without danger. No serious side effects were noted particularly with the oral form and it was far better tolerated by children, who received relatively higher dosage than most adults. The only contra-indication is for patients with manifest decompensation of vital organs, or fevers. Mebadin injection and Mebadin tablets are discontinued products.
