Ivermectin kills by interfering with nervous system and muscle function of the microfilariae. Ivermectin has been shown to reduce the occurrence of blindness, and to reduce the occurrence and severity of skin symptoms. An evolving treatment for oncocerciasis is doxycycline, which has been shown in studies to kill Wolbachia, an endosymbiotic rickettsia-like bacteria that appears to be required for the survival of the O.volvulus macrofilariae and for embryogenesis.
