What It Is and How It Works
Ivermectin is an antiparasitic agent used to treat infections like onchocerciasis (river blindness) and lymphatic filariasis in humans, along with external infestations such as scabies. It functions by targeting the nerve and muscle cells of parasites, causing paralysis and eventual death of the parasite. For technical audiences, ivermectin binds selectively to glutamate-gated chloride ion channels present in invertebrate muscle and nerve cells, increasing permeability to chloride ions and leading to paralysis.
Indications / Uses
In humans, the primary approved uses of ivermectin are for the treatment of various parasitic infections, including:
- Onchocerciasis: Also known as river blindness, caused by the parasitic worm Onchocerca volvulus.
- Lymphatic Filariasis: A disease manifesting as severe swelling, due to parasitic worms.
- Strongyloidiasis: An intestinal parasitic infection.
Ivermectin is also used off-label for treating conditions like scabies and head lice, under the direction of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including tablets, creams, and lotions. The dosing regimen largely depends on the type of infection being treated, the patient\’s weight, and other health considerations. For instance:
- Tablets: Commonly used for treating intestinal and systemic parasitic infections.
- Topical Creams/Lotions: Typically prescribed for conditions like scabies.
Dosing adjustments may be necessary for individuals with liver or kidney impairment, and it is important to follow the clinician\’s guidance closely.
How to Take It Correctly Step-by-Step
For oral forms, ivermectin is usually taken on an empty stomach with water. Here’s a general guideline to ensure proper adherence:
- Read the prescription label: Follow the specific dosing schedule provided by your healthcare provider.
- Timing: Take the medication at a set time to maintain consistent levels in your body.
- Missed Dose: If you miss a dose, take it as soon as you remember. If it\’s almost time for the next dose, skip the missed dose—do not double the dose.
- Storage: Store at room temperature, away from moisture and heat. Ensure it’s kept out of reach of children.
- Avoid Alcohol: Alcohol may increase certain side effects of ivermectin.
