Ivermectin is an antiparasitic medication that is used to treat various infections caused by parasites. Here's an overview:
Uses
1. Human Medicine
Parasitic Infections
Ivermectin is primarily used to treat conditions like onchocerciasis (river blindness), lymphatic filariasis, and strongyloidiasis. It is also effective against other parasitic infections such as scabies and head lice.
Off-Label Uses
There has been interest in using ivermectin for COVID-19, but scientific evidence does not support its efficacy for this purpose.
2. Veterinary Medicine
Animal Health
Ivermectin is widely used in veterinary medicine to prevent and treat parasitic infections in animals, including heartworm, mites, and gastrointestinal worms in livestock and pets.
Mechanism of Action
Ivermectin works by binding to and activating glutamate-gated chloride channels in the nerve and muscle cells of parasites, causing paralysis and death of the parasite. This mechanism is highly specific to invertebrates, making it safe for use in humans and animals.
Dosage and Administration
Oral Tablets
Typically administered in tablet form for human use. The dosage depends on the type and severity of the infection.
Topical Formulations
Used for treating external parasitic infections such as scabies and lice.
Injectable and Oral Forms for Animals Administered according to species and weight.
Safety and Side Effects
Side Effects
Common side effects include dizziness, pruritus (itching), and nausea. Severe adverse effects are rare but can include neurological effects.
Contraindications
Ivermectin should not be used in individuals with a history of hypersensitivity to the drug. It should be used with caution in individuals with conditions like asthma and liver disease.
COVID-19
Despite initial claims, large-scale studies and reviews by health authorities such as the FDA and WHO have not found ivermectin to be effective in preventing or treating COVID-19 [❞] [❞].
Ongoing Research
Research continues to explore other potential uses and to better understand the drug's safety profile.
Conclusion
Ivermectin is a crucial medication in the treatment of various parasitic infections in both humans and animals. While it is highly effective for its approved uses, its application in other areas, such as COVID-19, remains unsupported by rigorous scientific evidence.
