What It Is and How It Works
Ivermectin is a medication used to treat a variety of parasitic infections. It works by binding to glutamate-gated chloride ion channels, which leads to increased permeability of cell membranes to chloride ions. This results in paralysis and death of the parasite.
While its primary mechanism targets parasites, ivermectin\’s modulation of certain receptor pathways has spurred interest into potential applications beyond parasitic infections.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections in humans, including lice, scabies, and certain types of roundworm infections. In veterinary medicine, it\’s commonly used to treat heartworm disease and other parasitic infestations in animals.
Unofficially, ivermectin has been studied for a variety of potential uses, although these require additional research and should only be considered under the supervision of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available primarily in tablet form for human consumption. Other forms, such as topical and injectable formulations, are typically reserved for veterinary use.
For specific dosing, the weight of the individual or the type of infection being treated will guide dosing. It is crucial to adhere to the dosing regimen prescribed by a healthcare provider. Factors such as liver function and potential drug interactions must be considered when determining the appropriate dose.
How to Take It Correctly Step-by-Step
Ivermectin should be taken on an empty stomach with a full glass of water. If a dose is missed, take it as soon as remembered unless it is close to the time of the next dose—never double up doses. Store ivermectin at room temperature away from moisture and heat.
Do not share your medication with others, and avoid combining it with alcohol as this can exacerbate side effects.
