Potential benefits of Ivermectin

Ivermectin typically is administered orally as tablets. It treats onchocerciasis, a human filarial disease caused by the helminth onchocercid volvulus. Although Ivermectin does not kill the adult parasite, it helps you get rid of the microfilariae, the accumulation of which in the eye ultimately contributes to blindness. Treating parasitic infections helps to enhance your quality of life. In patients with weakened defense systems, curing roundworm infections causes a significant reduction in the risk of developing a severe or life-threatening infection. Ivermectin cream /tablet is categorized under the class of medications known as anthelmintic, which paralyzes and kills parasites.

Ivermectin oral tablets are used for short-term treatment. It comes with serious complications if you do not take it as prescribed.
