What It Is and How It Works
Ivermectin is an anthelmintic agent, which means it is designed to destroy parasitic worms. It works by binding to certain parasites\‘ nerve and muscle cells, increasing their permeability to chloride ions, which ultimately results in the death of the parasite. This mechanism is effective primarily for external parasites and those in the gastrointestinal tract.
Indications / Uses
Ivermectin is primarily used for the treatment of parasitic infections such as onchocerciasis (river blindness), strongyloidiasis, and scabies. It is sometimes used off-label in the treatment of other parasitic infections but should only be done under medical supervision. While it has been discussed for other uses, such as viral infections, these are not universally endorsed and lack robust supporting evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin for human use is typically available in oral tablet form. The dosing of ivermectin can vary depending on the specific parasitic infection being treated. Factors influencing dosing include the patient\’s age, weight, liver function, and severity of the condition. It is vital for patients to follow the prescription and guidance of a healthcare professional strictly.
How to Take It Correctly Step-by-Step
Taking ivermectin correctly involves several steps. It is usually taken on an empty stomach with water. If a dose is missed, consult with a healthcare provider or pharmacist before taking additional doses. Store ivermectin at room temperature away from excess moisture and heat. Avoid common errors such as taking extra doses, discontinuing use prematurely, or sharing the medication.
