What It Is and How It Works
Ivermectin is an antiparasitic medication typically prescribed to treat infections caused by certain parasites.

By eliminating the parasites, ivermectin can relieve the symptoms caused by the infection.

In veterinary medicine, it\’s also widely used to treat parasitic infections in animals. Some have explored its off-label use for other infectious diseases, although such uses should only be pursued under strict medical guidance due to mixed evidence and safety concerns.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form, as well as in topical creams and lotions primarily for skin conditions like rosacea. The dosing greatly depends on the condition being treated and factors such as the patient’s weight, liver function, and overall health.
