What It Is and How It Works
Ivermectin is an antiparasitic medication that is effective against a variety of parasites. It binds to invertebrate muscle and nerve cells, causing paralysis and death of the parasite. While it plays a crucial role in veterinary medicine, its use in humans is specific to certain parasitic infections like onchocerciasis and strongyloidiasis.
Indications / Uses
In humans, ivermectin is mainly indicated for treating parasitic infections such as onchocerciasis (river blindness) and intestinal strongyloidiasis. In veterinary medicine, it treats various parasites in livestock and pets. Off-label use in humans should only occur under medical supervision, and currently, it is not a recommended treatment for viral infections like COVID-19 by reputable health authorities.
Dosage Forms and Typical Dosing Considerations
Ivermectin comes in several forms: oral tablets for human use, and injectable or topical formulations for veterinary use. Dosing in humans depends on the type and severity of the infection, patient\’s weight, and other health conditions. For precise dosing, always follow healthcare professionals\’ specific instructions, as misuse can lead to adverse effects.
How to Take It Correctly Step-by-Step
The correct administration of ivermectin involves adhering to prescribed doses. Typically, it should be taken on an empty stomach with water. If a dose is missed, it should be taken as soon as remembered, unless the next scheduled dose is near. Doubled doses should not be used to make up for missed doses. Proper storage in a cool, dry place is advised.
