What It Is and How It Works
Ivermectin is an antiparasitic medication that interferes with the nervous system of parasites, leading to their paralysis and death. In veterinary models, such as horse paste, it is commonly used to treat worms and other parasites. In humans, it is approved for treating specific parasitic infections. Its mechanism involves binding to muscle and nerve cells of parasites, causing increased permeability and leading to paralysis.
Indications / Uses
For veterinary use, ivermectin is primarily indicated for parasitic infections in animals including horses. Off-label discussion has included its use in COVID-19, but such applications remain controversial and lack robust clinical support. It is crucial that off-label use only occurs under professional supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, such as oral tablets and topical formulations for human use, and paste for equine use. Dosing decisions in veterinary medicine depend on the type of animal and illness. For humans, dosing is based on body weight for approved indications and should only be prescribed by a healthcare professional. Special populations such as pregnant or breastfeeding women need professional evaluation and guidance.
How to Take It Correctly Step-by-Step
If prescribed for human use, adhere strictly to the instructions on the prescription label. It should be taken on an empty stomach with water and at the same time of day. If a dose is missed, it should be taken as soon as remembered unless it is near the time for the next dose. Avoid doubling doses. Store at room temperature away from moisture and heat.
