What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitics. It works by binding to certain proteins in parasites, leading to paralysis and death of the parasite. This interrupts the life cycle of the parasites and helps clear infections from the body. Ivermectin is particularly effective against a range of parasitic worms, as well as external parasites like lice and mites.
Indications / Uses
Ivermectin is primarily approved for treating parasitic infections. These include:
- Onchocerciasis: Also known as river blindness, this condition is caused by a worm that is transmitted through bites from infected blackflies.
- Lymphatic filariasis: This disease is caused by infection with certain species of parasitic worms and can lead to severe swelling and disability.
- Strongyloidiasis: A condition caused by infection with a roundworm.
- Scabies and lice: Both are infestations caused by mites and lice, respectively.
Off-label uses are reported but should be discussed and monitored by a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available mainly in two forms for human use:
- Oral Tablets: This is the most common form used to treat internal parasitic infections. The dosage typically depends on body weight.
- Topical Creams and Lotions: These are primarily used for external infestations like head lice and scabies.
Dosing is largely determined by the specific condition being treated, the patient\’s body weight, and the patient\’s overall health. Dosage adjustments may be needed for elderly patients or those with liver impairment.
