For antifilarials, based on the evidence provided, the Committee decided to retain ivermectin and diethylcarbamazine, and add albendazole for combination therapy for both children and adults. There was no reason for diethylcarbamazine to be on the Complementary List especially since it is recommended by WHO guidelines as the medicine of choice for mass drug administration in countries endemic for lymphatic filariasis but without either onchocerciasis or loiasis.
