What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used in the treatment of specific nematode (roundworm) infections. It works by binding to glutamate-gated chloride ion channels in the nerve and muscle cells of parasites, causing paralysis and death of the parasitic organism. This action is selective for invertebrates, making it a valuable tool against parasitic infections without causing harm to human cells.
Indications / Uses
Ivermectin is approved for use in treating:
- Onchocerciasis: Commonly known as river blindness, caused by Onchocerca volvulus.
- Lymphatic filariasis: A tropical parasitic disease affecting the lymph nodes.
- Scabies: A skin condition caused by tiny mites.
- Strongyloidiasis: A threadworm infection affecting the intestines.
The use of ivermectin for COVID-19 has been discussed widely, but it is not an FDA-approved treatment for viral infections. Such off-label use should always occur under the strict supervision of a healthcare provider due to mixed evidence and considerable debate.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including:
- Oral tablets: Doses often depend on the specific condition being treated and patient weight.
- Topical creams and lotions: Used mainly for skin conditions like scabies.
Dosing typically depends on the patient\’s weight, medical condition, and specific parasite involved. It is imperative that patients follow their physician\’s instructions regarding dosage, as incorrect dosing can lead to ineffective treatment or increased risk for side effects.
How to Take It Correctly Step-by-Step
To ensure the effectiveness of ivermectin, follow these general guidelines:
- Take on an empty stomach with a full glass of water unless directed otherwise by your healthcare provider.
- Maintain consistent timing for doses if multiple are prescribed over time.
- If a dose is missed, take it as soon as possible unless it\’s close to the timing of the next dose. Do not double the dose.
- Store at room temperature, away from light and moisture.
Avoid alcohol as it may increase the risk of experiencing certain side effects like dizziness or headache.
