What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat infections caused by certain kinds of parasites. The drug works by binding with high affinity to glutamate-gated chloride ion channels in invertebrate nerve and muscle cells, resulting in increased permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite.
Indications / Uses
Ivermectin is primarily indicated for the treatment of infections such as:
- Onchocerciasis: Also known as river blindness, a disease caused by parasitic worms spread by blackfly bites.
- Strongyloidiasis: An intestinal disease caused by the parasitic roundworm Strongyloides stercoralis.
- It is occasionally used off-label for other parasitic infections under medical supervision.
Ivermectin\’s use for COVID-19 remains controversial and is not approved by health authorities for this purpose; consult healthcare professionals for validated treatment protocols.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms:
- Tablets: Most commonly prescribed for parasitic infections.
- Topical creams and lotions: Used for treating head lice and skin conditions like rosacea.
The typical dosing of oral tablets depends on the condition being treated, the patient\’s weight, age, and other health considerations. Medical practitioners need to carefully adjust dosages in patients with liver impairments or those who are pregnant or breastfeeding.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach with water, one hour before or two hours after meals.
- Follow the prescribed schedule strictly; do not adjust doses without medical advice.
- If you miss a dose, take it as soon as you remember unless it’s nearly time for your next dose.
- Avoid alcohol during treatment, as it can exacerbate dizziness or side effects.
- Store in a cool, dry place away from direct sunlight.
Do not share your medication with others, and complete the full course even if symptoms improve.
