Treatment

People who are found to be infected with O. volvulus should be treated in order to prevent the long-term skin damage and blindness. The recommended treatment is ivermectin, which will need to be given every 6 months for the life span of the adult worms or for as long as the infected person has evidence of skin or eye infection. Ivermectin kills the larvae and prevents them from causing damage but it does not kill the adults. There is a promising new treatment using doxycycline that kills the adult worms by killing the Wolbachia bacteria on which the adult worms depend in order to survive. If you are infected, it is possible that your doctor will want to treat you both with the ivermectin and the new treatment. Before any treatment is begun, however, you need to make sure that you are not also infected with Loa loa, another filarial parasite found in central Africa that is sometimes found in the same areas where O. volvulus is found, because Loa loa can be responsible for severe side effects to the medications used to treat onchocerciasis.
