What It Is and How It Works
Ivermectin is an antiparasitic medication that disrupts nerve and muscle function of parasites, leading to their death. It binds selectively and with high affinity to certain ion channels that are critical for the function of neurons and muscle cells in invertebrates. This action effectively paralyzes or kills the parasites, helping eliminate them from the body.
Indications / Uses
The primary approved uses for ivermectin include the treatment of strongyloidiasis, a parasitic disease caused by the roundworm Strongyloides stercoralis, and onchocerciasis, also known as river blindness. Additionally, ivermectin is approved for treating other parasitic infections like lice and scabies when topical forms are utilized.
While research has explored ivermectin\’s potential in treating other conditions, it should be used off-label only under professional guidance due to varying evidences of efficacy and safety profiles.
Dosage Forms and Typical Dosing Considerations
Oral ivermectin is generally available in tablet form, with common strengths ranging from 3 mg to 12 mg. Topical ivermectin is available as creams and lotions primarily for treating lice and skin conditions. The appropriate form, concentration, and dosing frequency depend on the specific condition being treated, patient age, weight, and overall health status.
Patients should always follow their healthcare provider’s prescription and advice to ensure safety, as dosing adjustments may be necessary in individuals with liver or kidney impairment, and special populations such as pregnant or breastfeeding individuals.
How to Take It Correctly Step-by-Step
- Take ivermectin tablets on an empty stomach with a full glass of water.
- Avoid taking the medication with food to enhance absorption.
- If a dose is missed, take it as soon as remembered unless it\’s almost time for the next dose. Do not double the dose to make up for a missed one.
- Store at room temperature, away from moisture and heat.
- Avoid alcohol as it may exacerbate side effects.
- Complete the full course as prescribed even if symptoms improve.
