What It Is and How It Works
Ivermectin is an antiparasitic agent used to treat several types of parasitic infections in humans and animals, such as river blindness (onchocerciasis), strongyloidiasis, and scabies. It works by binding to certain channels on the nerve and muscle cells of parasites, causing paralysis and death of the parasite. For humans, this can lead to the resolution of the infection and reduction of symptoms related to these parasitic diseases.
Indications / Uses
In humans, ivermectin is primarily approved for the treatment of parasitic conditions like:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Head lice, scabies, and other parasitic infections
Though there have been discussions about off-label use in other conditions, such uses should only occur under the supervision of a qualified healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including tablets, topical creams, and lotions. The dosing depends on the specific infection being treated, the patient\’s weight, and other health considerations. It is crucial to follow the prescribed regimen outlined by a healthcare professional, as the wrong dosing can lead to ineffective treatment or adverse effects.
How to Take It Correctly Step-by-Step
- Follow the dosing instructions provided by your healthcare professional.
- The oral form is typically taken on an empty stomach with water.
- If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose.
- Store ivermectin at room temperature away from moisture and heat.
Common mistakes include taking higher doses than prescribed, splitting or crushing tablets unless advised, or securing unapproved ivermectin formulations purported for human use.
