What It Is and How It Works
Ivermectin is an antiparasitic agent that disrupts the nerve and muscle functions of parasites by binding to chloride ion channels, which increases the permeability of the cell membranes, leading to paralysis and death of the parasite. This action is highly specific to certain parasites and does not affect humans when used appropriately.
Technically, ivermectin enhances the release of gamma-aminobutyric acid (GABA) at presynaptic neurons, contributing further to the paralysis effect on the parasites while taking advantage of the fact that GABA neurotransmitters are not commonly present in human peripheral neurons.
Indications / Uses
Ivermectin is primarily used to treat infections caused by certain parasitic worms such as onchocerciasis (river blindness), strongyloidiasis (intestinal parasites), and diseases caused by ectoparasites like head lice and scabies. It is also occasionally used off-label for treating other parasitic infections under the care of a health professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in tablets, topical solutions, and creams. Dosage depends on the type of infection. Factors that influence dosing include body weight, severity of the infection, and other underlying health conditions. For example, liver dysfunction may necessitate dosage adjustment, and healthcare providers often consider the potential risk versus benefit ratio when prescribing to pregnant or breastfeeding individuals.
Always follow the dosing instructions provided by your healthcare provider and do not self-prescribe or alter the dosage without professional advice.
How to Take It Correctly Step-by-Step
To take ivermectin correctly:
- Take the tablet with water on an empty stomach.
- Do not chew or crush the tablet.
- If you miss a dose, take it as soon as you remember unless it\’s almost time for your next dose; do not double up.
- Store ivermectin at room temperature away from moisture and heat.
- Avoid alcohol as it can increase the risk of some side effects.
