Effectiveness of mebendazole in Trichuris trichiura; a report on 2 cases of mild infection.

Two admitted patients, a 5-year-old Filipino girl and a 29-year-old Indonesian man, who were diagnosed otherwise were concurrently found to harbour Trichuris trichiura eggs in stoll specimens containing 3,300 and 30 eggs per gram feces (EPG), respectively. A satisfactory response was obtained with administration of mebendazole in the recommended dose of 100 mg twice daily for three consecutive days. Repeated post-treatment fecal examinations revealed 0 EPG. Adverse reaction, either physical or laboratory, due to the anthelmintic was negative. The study indicates that the effectiveness of mebendazole on mild infection with T. trichiura is excellent without any untoward effect.
