What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitic agents. It works by binding to parasite nerve and muscle cells, leading to paralysis and death of the parasite. This mechanism helps rid the host of the infection, leading to recovery from the parasitic disease. While ivermectin is effective against several types of parasites, its action is limited to those it can bind effectively.
Indications / Uses
Ivermectin is primarily indicated for treating certain parasitic infections such as onchocerciasis (river blindness) and strongyloidiasis. It can also be used to manage scabies and lice, though these uses may vary regionally. Off-label, it has been discussed for a variety of conditions, but any off-label use should only be conducted under the guidance of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly prescribed in oral tablet form. Dosing is individualized based on the type of infection, weight of the patient, and response to treatment. It is crucial for patients to adhere to the dosing regimen outlined by their healthcare provider and not to self-adjust their dose.
