What It Is and How It Works
Ivermectin is classified as an antiparasitic agent. It works primarily by binding selectively and with high affinity to certain muscle and nerve cells of parasites, causing paralysis and death of these organisms. This action is beneficial in eliminating parasitic infections such as intestinal worms and other types of parasitic infestations.
In technical terms, ivermectin enhances inhibitory neurotransmission through increasing the permeability of the cell membrane to chloride ions, disrupting normal nerve and muscle function in parasites without harming the host due to its selective mechanism.
Indications / Uses
Ivermectin tablets are primarily indicated for the treatment of parasitic infections such as:
- Strongyloidiasis of the intestinal tract
- Onchocerciasis, also known as river blindness
While ivermectin is sometimes used off-label for other conditions, these uses should only occur under the guidance of a healthcare professional, as evidence and safety may vary significantly.
Dosage Forms and Typical Dosing Considerations
Ivermectin typically comes in tablet form for oral administration. The dosing of ivermectin depends on the type and severity of the infection as well as the patient\’s weight and overall health status. The exact dosing should always be determined by a healthcare professional based on individual needs and circumstances. Factors such as liver and kidney function and concurrent medications need to be considered during dosing.
How to Take It Correctly Step-by-Step
Here are some general guidelines for taking ivermectin tablets:
- Take ivermectin on an empty stomach with a full glass of water.
