What It Is and How It Works
Ivermectin is an antiparasitic drug that works by binding to specific chloride ion channels in nerve and muscle cells of parasites. This binding causes an increase in the permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. It is effective against a wide range of parasites, including some that are particularly challenging to treat with other medications.
Indications / Uses
The primary FDA-approved uses of ivermectin in humans include the treatment of:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Other parasitic diseases such as filariasis and scabies in an off-label capacity
Off-label uses should only be considered under the supervision of a healthcare professional, as they may not be appropriate for all patients.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in tablet form for human use. The specific dosage depends on the type of infection being treated, as well as the patient’s weight, age, and overall health. It is crucial to follow the dosing instructions provided by a healthcare professional to ensure optimal effectiveness and minimize potential side effects.
Factors such as liver impairment, pregnancy, or the presence of other medical conditions can influence dosing decisions. Therefore, all dosing regimens should be tailored by healthcare professionals to suit individual patient needs.
