Quick Facts
- Ivermectin is used to treat certain parasitic infections.
- It works by binding to the parasite\’s nerve and muscle cells, causing paralysis and death.
- Common forms include oral tablets and topical creams/lotions.
- Used for conditions like river blindness, intestinal strongyloidiasis, and sometimes lice and scabies.
- Potential side effects include dizziness, nausea, and rash.
- Ivermectin can interact with other medications, so disclose all drugs you\’re taking to your healthcare provider.
- Special caution is advised for pregnant or breastfeeding women and young children.
- Seek urgent medical help if you experience severe allergic reactions or neurological issues.
What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to a class of medications called avermectins. It is used to treat infections caused by certain parasites. It works by binding to parts of the parasites\‘ cells, causing paralysis and death, thus eliminating the infection.
On a molecular level, ivermectin binds with high affinity to glutamate-gated chloride ion channels, which are vital for nerve and muscle function in invertebrate parasites. The disruption of these channels, predominantly found in the parasites but not in mammals, leads to increased permeability of the cell membrane to chloride ions, causing hyperpolarization of the cell, resulting in paralysis and eventual death of the parasite.
Indications / Uses
Ivermectin is primarily used to treat parasitic infections, including:
- River blindness (onchocerciasis)
- Intestinal strongyloidiasis
- Scabies (in specific cases)
- Head lice (topical form)
While ivermectin has been studied for off-label uses, any use beyond the label should only be conducted under professional medical guidance due to the varying quality of evidence supporting such applications.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets and topical creams/lotions. The dosing of ivermectin varies depending on the condition being treated, patient age, weight, liver and kidney function, and other comorbidities.
For oral ivermectin, dosing is often determined by body weight. Patients should follow the dosage prescribed by their healthcare provider, tailored to their specific condition and medical background.
How to Take It Correctly Step-by-Step
When taking ivermectin:
- Follow the prescription label or your healthcare provider’s instructions carefully.
- Take tablets with a full glass of water on an empty stomach, unless directed otherwise.
- If a dose is missed, take it as soon as you remember unless it\’s near the time of the next dose. Do not double the dose.
