Moxidectin was approved for onchocerciasis (river-blindness) in 2018 for people over the age of 11 in the United States based on two studies. [5] There is a need for additional trials, with long-term follow-up, to assess whether moxidectin is safe and effective for treatment of nematode infection in children and women of childbearing potential.

Treating a horse with regular dewormer when they have the worms inside of them may cause the worms to migrate all at once, causing rupture of the intestines and lead to death. [11] Recommendations for deworming horses include performing fecal egg counts to determine what kind of protection each individual horse requires and alternating products ...
