What It Is and How It Works
Ivermectin is an antiparasitic agent mainly used to treat infections caused by certain parasites. It works by interfering with the nervous system of the parasites, causing paralysis and eventually the death of the parasitic organisms. The drug enhances the release of neurotransmitters in the parasites which is toxic to them but harmless to vertebrates at recommended doses. This leads to the elimination of parasites such as lice, scabies, and various types of worms.
Indications / Uses
The primary use of ivermectin is to treat parasitic infections. It is FDA-approved for the treatment of conditions like onchocerciasis (river blindness), intestinal strongyloidiasis, and some cases of ectoparasites such as head lice and scabies. While there has been interest in its potential use for other conditions, such as COVID-19, these are off-label and should only be considered under medical supervision and within the context of ongoing research.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form, with strength and dosage depending on the specific parasitic infection being treated. Topical formulations are available for skin conditions like rosacea. Dosing depends on factors such as the type of infection, the patient’s weight, age, and kidney/liver function. Special caution is advised for pregnant and breastfeeding women, as well as those with liver issues, where professional guidance is paramount.
How to Take It Correctly Step-by-Step
- Timing: Take the oral form on an empty stomach with a full glass of water, unless directed otherwise by your doctor.
- Adherence Tips: Following the dosing schedule precisely is crucial for effectiveness.
- Storage: Keep it at room temperature, away from moisture and heat.
- Missed Dose: Take it as soon as you remember unless it\’s almost time for the next dose. Do not double the dose to catch up.
- Common Mistakes: Avoid self-medicating for unapproved conditions and do not share medication with others.
