What It Is and How It Works
Ivermectin is an antiparasitic medication used predominantly to treat infections caused by various parasites. It belongs to a class of drugs known as anthelmintics. The parasite-fighting property of ivermectin works by binding selectively to glutamate-gated chloride ion channels found in invertebrate nerve and muscle cells. By increasing the permeability of the cell membrane to chloride ions, the drug leads to paralysis and eventual death of the parasites.
Indications / Uses
Ivermectin is primarily used for treating parasitic infections such as:
- Onchocerciasis (River Blindness): An infection caused by a parasitic worm transmitted through blackfly bites.
- Strongyloidiasis: An intestinal infection caused by the roundworm Strongyloides stercoralis.
- Scabies: A skin infestation by the mite Sarcoptes scabiei.
- Lice Infections: Topically used to treat head lice in some formulations.
Although studied for other uses, including viral infections, these applications remain off-label and should be approached cautiously under professional supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets, topical creams, and veterinary injections. The form used depends on the specific infection being treated.
- Oral Tablets: Commonly used in the treatment of onchocerciasis and strongyloidiasis.
- Topical Creams: Used for treating conditions like scabies and head lice.
Dosing varies based on factors such as the infection type, patient weight, and overall health. Typical dosing involves administration based on body weight, but specific dosing should be determined by a healthcare provider. Modified dosing may apply for those with liver impairments or severe health conditions, and close consultation with a clinician is crucial.
How to Take It Correctly Step-by-Step
- Follow Prescription: Always adhere to the dosing schedule provided by your healthcare provider.
- Oral Dosage: Take with water on an empty stomach for optimal absorption, unless otherwise directed.
- Missed Dose: Take as soon as you remember if not close to the next dose. Do not double doses to make up for a missed one.
- Storage: Store in a cool, dry place away from direct sunlight and moisture.
- Adherence Tips: Set reminders and use a medication planner to avoid missing doses.
- Common Mistakes: Avoid altering dosage without consulting a healthcare provider. Do not share medication with others.
