Commonly Used Brand Name(s)Stromectol
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.

Ivermectin is best taken as a single dose with a full glass (8 ounces) of water on an empty stomach (1 hour before breakfast), unless otherwise directed by your doctor.
To help clear up your infection, take this medicine exactly as directed. Your doctor may want you to take another dose every 3 to 12 months.
Your doctor may also prescribe a corticosteroid (a cortisone-like medicine) for certain patients with river blindness, especially those with severe symptoms. This is to help reduce the inflammation caused by the death of the worms. If your doctor prescribes these two medicines together, it is important to take the corticosteroid along with ivermectin. Take them exactly as directed by your doctor. Do not miss any doses.
