What It Is and How It Works
Ivermectin is an antiparasitic agent often used in the treatment of various parasitic infections. It operates by interfering with the nervous system and musculature of parasites by binding to the glutamate-gated chloride ion channels, which in turn increases cell membrane permeability and leads to paralysis and death of the parasites.
Indications / Uses
The FDA-approved uses of ivermectin include the treatment of onchocerciasis (river blindness) and strongyloidiasis of the intestinal tract. Additionally, it\’s used for treating head lice and rosacea when prescribed as a topical agent.
Multiple claims have been made regarding its off-label use for conditions like COVID-19; however, such uses remain controversial and should always be under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form for oral administration and as a topical cream. The dosage depends on specific factors such as the specific infection being treated, patient’s weight, age, and overall health condition. Pediatric use and dosages for patients with liver or kidney issues require careful medical guidance.
How to Take It Correctly Step-by-Step
Oral ivermectin should generally be taken on an empty stomach with water. Follow the prescribed dose precisely without altering it. In case a dose is missed, ask your healthcare provider for advice. Store medications in a cool, dry place, away from direct sunlight.
