Vermox Orange Flavoured Tablets are indicated for the treatment of single or mixed helminthic infestations. Clinical studies have shown mebendazole to be effective in the treatment of Enterobius vermicularis (threadworm), Ascaris lumbricoides (roundworm), Trichuris trichiura (whipworm), and of Ancylostoma duodenale and Necator americanus (hookworm). Efficacy varies as a function of such factors as pre-existing diarrhoea, gastrointestinal transit time, degree of infection, and helminth strain.
