What It Is and How It Works
Ivermectin is an antiparasitic medication originally introduced for veterinary use and later approved for human use. It effectively treats several parasitic diseases, such as onchocerciasis (river blindness) and strongyloidiasis. It works by targeting and binding to specific proteins in parasites, causing an increase in the permeability of cell membranes to chloride ions. This process ultimately leads to paralysis and death of the parasite, thus clearing the infection.
Indications / Uses
The FDA has approved ivermectin for the treatment of certain parasitic infections in humans, such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Head lice (as a topical treatment)
- Scabies (as a topical treatment)
Despite widespread interest and media coverage, ivermectin is not approved for the prevention or treatment of COVID-19. Any such use should only occur within the context of a clinical trial or after a healthcare professional has evaluated specific clinical circumstances.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms including tablets for oral administration and topical formulations for skin conditions. The dosing varies significantly depending on the condition being treated.
The typical considerations include age, weight, liver and kidney function, and potential drug interactions. Adult dosages for parasitic infections typically range from a single dose of 150-200 micrograms per kilogram, but the exact dosing should always follow the prescription and guidance of a healthcare provider.
How to Take It Correctly Step-by-Step
Taking ivermectin correctly is crucial to ensure its effectiveness and reduce the risk of adverse effects:
- Take ivermectin on an empty stomach, at least one hour before or two hours after meals, unless otherwise directed by your healthcare provider.
- Swallow the tablet with a full glass of water.
- If a dose is missed, take it as soon as you remember unless it\’s close to the time of your next dose; in that case, skip the missed dose. Do not double the dose to catch up.
- Store ivermectin at room temperature, away from excessive heat and moisture.
Side Effects Common to Serious
Ivermectin can cause side effects, ranging from mild to severe. Common side effects include:
- Dizziness
- Nausea
- Diarrhea
- Rash
Less common but more serious side effects can occur, such as:
- Hypersensitivity reactions (itching, hives)
- Swelling (especially of the face or limbs)
- Severe dizziness or difficulty breathing
If you experience these severe symptoms, seek urgent medical attention.
Contraindications & Precautions
Ivermectin is contraindicated in individuals with known hypersensitivity to the drug or any of its components. Special caution is advised for those with liver or kidney dysfunction, pregnant or breastfeeding women, and pediatric patients unless prescribed by a healthcare provider.
Elderly patients may have increased sensitivity to the drug and may require close monitoring during treatment.
Drug, Food, and Supplement Interactions
Ivermectin can interact with several other drugs, affecting how either drug works and increasing the risk of side effects. Notable interactions include:
- Warfarin: May increase the risk of bleeding due to changes in drug concentration.
- Other medications processed by the liver, which can change ivermectin\’s metabolism, efficacy, and side effect profile.
It is important to notify your healthcare provider of all medications being taken, including over-the-counter medicines, vitamins, and herbal supplements.
