Ivermectin is mainly used to treat infections caused by parasitic worms and external parasites. Approved uses include the treatment of onchocerciasis (river blindness) and lymphatic filariasis. It is also effective against scabies and head lice infestations. Off-label, it has been studied for other potential uses; however, these are under investigation, and results are varied.

Ivermectin is commonly available in oral tablet form. The dosing of Ivermectin can depend on a variety of factors including the specific infection being treated, patient\’s body weight, and medical history. It is vital that dosage is guided by a prescription from a qualified healthcare professional, as improper dosing can lead to ineffective treatment or adverse effects.
