Uses
Uses of This Medicine
Ivermectin is used in the treatment of certain worm infections. It is used to treat river blindness (onchocerciasis) and a certain type of diarrhea (strongyloidiasis). It may also be used for some other kinds of worm infections.
Ivermectin appears to work by paralyzing and then killing the offspring of adult worms. It may also slow down the rate at which adult worms reproduce. This results in fewer worms in the skin, blood, and eyes.
Ivermectin is available only with your doctor’s prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, ivermectin is used in certain patients with the following medical condition:
