What It Is and How It Works
Ivermectin is a medication known for its effectiveness against various parasites. It acts by binding selectively with high affinity to glutamate-gated chloride ion channels which occur in invertebrate nerve and muscle cells. This increases the permeability of the cell membrane to chloride ions, with hyperpolarization of the nerve or muscle cell, leading to paralysis and death of the parasite.
This mechanism particularly affects parasites without crossing the blood-brain barrier significantly, allowing for selective targeting of parasites without harming the host.
Indications / Uses
Ivermectin is approved for use in treating several parasitic infections. Primarily, it is used to manage diseases such as:
- Strongyloidiasis: A parasitic disease caused by the roundworm Strongyloides stercoralis.
- Onchocerciasis (River blindness): A condition prompted by the Onchocerca volvulus worm, characterized by skin and eye inflammation.
- Lice and Scabies: Ivermectin is occasionally used off-label to treat infestations like lice and scabies, under the direction of a healthcare provider.
Off-label or unapproved uses should always be pursued under the guidance of a healthcare provider, given the ongoing research and varying support for such uses.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms including oral tablets, topical creams, and lotions. The dosage and form depend on the specific condition being treated, the patient\’s weight, age, kidney and liver function, and other concurrent medications.
Common dosing considerations include:
- Oral tablets: Often used for parasitic infections, dosing is generally weight-based.
- Topical forms: Used for skin conditions like rosacea, with application methods varying based on the specific product.
Always follow your prescription label or healthcare provider\’s directions, as dosing can be affected by numerous individual factors. Children and elderly patients require well-monitored dosing adjustments.
How to Take It Correctly Step-by-Step
For oral forms, take ivermectin on an empty stomach, about an hour before eating, with water. Follow these steps consistently:
- Timing: At least one hour before meals unless directed otherwise.
- Missed doses: If a dose is missed, take it as soon as remembered if close to the time; otherwise, skip to the next scheduled dose, avoiding doubling up.
- Storage: Store at room temperature, away from moisture and heat.
