What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to a class of drugs known as avermectins. It works by binding to certain chloride ion channels in the parasite\’s nerve and muscle cells, leading to its paralysis and death. This mechanism effectively clears the infection from the body.
Indications / Uses
Primarily, ivermectin is used to treat parasitic infections such as onchocerciasis (river blindness) and strongyloidiasis. In some regions, it\’s also utilized for scabies and lice. Though not approved for COVID-19 treatment, ivermectin has been discussed for this use; however, evidence supporting this is limited and should only occur under healthcare supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in oral tablet form, although topical forms exist for external parasite infections like head lice. The dosage depends on the type of infection and patient-specific factors such as weight. It\’s crucial to follow healthcare provider instructions, as incorrect dosages can lead to ineffective treatment or toxicity.
How to Take It Correctly Step-by-Step
Ivermectin should be taken on an empty stomach with water unless directed otherwise by your healthcare provider. If you miss a dose, take it as soon as you remember but skip it if it\’s almost time for your next dose. Avoid double dosing. Store ivermectin at room temperature and away from moisture.
