What It Is and How It Works
Ivermectin is an antiparasitic agent belonging to the avermectin class of drugs. It works by binding to specific chloride ion channels in the parasite\’s muscle and nerve cells. This action increases the permeability of the cell membranes to chloride ions, leading to paralysis and death of the parasite.
The drug’s mode of action is effective against various parasites, including those causing river blindness, intestinal strongyloidiasis, and certain off-label uses such as scabies and lice infestations.
Indications / Uses
The primary approved uses of ivermectin include treatment for:
- Onchocerciasis (river blindness): Caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: Caused by the intestinal parasite Strongyloides stercoralis.
Other conditions for which ivermectin may be prescribed off-label include:
- Scabies: Commonly used when topical treatments are not effective.
- Head Lice: Used in some cases, although not the primary treatment.
Off-label use should be guided by a clinician, considering the patient’s specific health needs and existing evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets and topical preparations. The oral tablet is the most common form prescribed for treating parasitic infections.
Dosage largely depends on the type of parasitic infection, patient\’s weight, and other individual health considerations. For instance, dosages may be adjusted for patients with liver or kidney impairment or those who are pregnant or breastfeeding.
It is vital to follow the dosing instructions provided by a healthcare practitioner or as specified on the prescription label.
How to Take It Correctly Step-by-Step
