What It Is and How It Works
Ivermectin works by binding to parts within invertebrate nerve and muscle cells, leading to paralysis and death of parasites. This is highly effective for organisms causing diseases such as river blindness and strongyloides. Technically, it increases the permeability of cell membranes to chloride ions, disrupting neural and muscle activity.
Indications / Uses
Ivermectin is approved primarily for treating parasitic infections. It is effective against:
- Onchocerciasis (river blindness)
- Intestinal strongyloidiasis
Off-label, ivermectin is sometimes used to treat:
- Scabies
- Rosacea
While off-label uses are increasing, they require more evidence for regular recommendation and should only be pursued under a healthcare provider’s supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin commonly comes in:
- Oral tablets
- Topical creams and lotions for particular skin conditions
Dosing is based on factors like the condition treated, body weight, and general health. Close adherence to prescribed doses is crucial to avoid unwanted side effects or toxicities. Special considerations are taken for kidney or liver impairments, and during pregnancy or lactation.
How to Take It Correctly Step-by-Step
- Take oral forms on an empty stomach for optimal absorption.
- If a dose is missed, take it as soon as remembered unless it\’s close to the next scheduled dose. Do not double dose.
