What It Is and How It Works
Ivermectin is an antiparasitic agent belonging to the avermectin class of drugs. Its primary mechanism involves binding to glutamate-gated chloride ion channels specific to invertebrates. This binding increases the permeability of cell membranes to chloride ions, resulting in paralysis and death of the parasites. While highly effective against a variety of parasites, ivermectin does not affect mammals in the same way as these chloride channels are absent in higher animals.
Indications / Uses
Ivermectin is primarily used to treat several parasitic infections, both in humans and animals. In humans, it’s efficacy is notable against:
- Onchocerciasis: Also known as river blindness, caused by the parasitic worm Onchocerca volvulus.
- Strongyloidiasis: An intestinal infection caused by the nematode Strongyloides stercoralis.
Veterinary applications are extensive, treating infections such as heartworm in dogs and other parasitic diseases in livestock. While ivermectin has been investigated for other uses, including potential antiviral activity, these applications remain under clinical scrutiny.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several dosage forms:
- Oral Tablets: Typically used for human infections.
- Topical Creams: Applied for skin conditions like rosacea.
- Injectable Forms: More common in veterinary medicine.
Dosing considerations depend on the specific infection, the patient’s age, weight, and overall health condition. It\’s crucial to follow the prescribing information or guidance provided by a healthcare professional.
How to Take It Correctly Step-by-Step
For oral administration:
- Take ivermectin on an empty stomach, at least one hour before or two hours after meals.
- Swallow the tablet with a full glass of water.
- In case of a missed dose, take it as soon as remembered unless it is close to the time for the next dose. Do not double doses.
- Store at room temperature, away from moisture and heat.
Avoid common mistakes such as altering the dose without a clinician\’s advice or mixing with alcohol, which might increase the risk of side effects.
