What It Is and How It Works
Ivermectin is an antiparasitic drug that is used to treat infections caused by certain types of parasites. It works by binding to invertebrate muscle and nerve cells, causing paralysis and death of the parasite. While officially approved for treating conditions like river blindness and intestinal strongyloidiasis, ivermectin\’s mechanism involves disrupting the normal neural and muscular function in parasites, making it effective against a variety of parasitic organisms.
Indications / Uses
The primary FDA-approved uses of ivermectin include the treatment of:
- Onchocerciasis (river blindness).
- Intestinal strongyloidiasis (roundworm infection).
In some countries and under certain conditions, ivermectin may be used off-label for other parasitic infections. However, the use of ivermectin for non-parasitic conditions, such as viral infections, remains controversial and should only be considered under professional healthcare guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including tablets and topical creams. The oral form is most commonly used for internal parasite infections. Typical dosing depends on the specific infection being treated, the patient’s weight, and the form of ivermectin. It\’s crucial for patients to follow their prescription label and consult their healthcare provider to ensure the correct dose is taken. Special considerations are necessary for people with liver or kidney disease, pregnant women, and those taking other medications.
