What It Is and How It Works
Ivermectin is an antiparasitic medication used predominantly to treat infections caused by roundworms, threadworms, and other parasites. It functions by binding to certain parasites\’ muscle and nerve cells, causing paralysis and death, thus effectively clearing the infection.
On a more technical level, ivermectin\’s binding inhibits the transmission of electrical activity in invertebrate nerve and muscle cells. The affected parasites are then expelled by the host\’s immune system.
Indications / Uses
Ivermectin is primarily indicated for treating numerous parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Lice and scabies (in certain cases)
In specific regions, ivermectin is used as part of mass drug administration programs to control parasites. Although there has been discussion about off-label uses, such as treating COVID-19, these applications should only occur under strict clinical supervision and guidelines.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form. The dosing varies based on the infection, patient\’s weight, and other health conditions:
- Tablets: Typically, a single oral dose is administered with water on an empty stomach.
- Conditions: Liver impairment, pregnancy, breastfeeding status, and other medications the patient is taking should be considered, as these can affect dose adjustments.
Always follow the advice of a healthcare professional for specific dosing.
How to Take It Correctly Step-by-Step
- Take the tablet on an empty stomach, at least one hour before or two hours after a meal.
