What It Is and How It Works
Ivermectin is an antiparasitic medication that is effective against various internal and external parasites, including those causing conditions such as river blindness (onchocerciasis) and intestinal strongyloidiasis. It works by binding to glutamate-gated chloride channels, prevalent in parasites\’ nerve and muscle cells, which increases the permeability of the cell membrane to chloride ions. This results in paralysis and death of the parasite.
Indications / Uses
Ivermectin is approved for treating several parasitic infections. Major human uses include:
- Onchocerciasis: Also known as river blindness, this disease is caused by the worm Onchocerca volvulus.
- Strongyloidiasis: An infection caused by a type of roundworm.
- Scabies: A skin infection caused by mites, often treated with topical ivermectin.
Additionally, ivermectin is used to deworm pets and livestock, leveraging its effectiveness against a wide range of parasites.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including tablets and topical preparations for human use, and injectable solutions or oral liquids for veterinary use. The form and dose depend on the type of infection being treated, the patient\’s age, weight, and medical conditions. It\’s crucial to adhere to the prescription label and physician\’s dosing guidance, as incorrect use can lead to treatment failure or adverse effects.
How to Take It Correctly Step-by-Step
When taking ivermectin, follow these general guidelines:
- Follow the prescription: Use the exact dose prescribed by your healthcare provider.
- Take on an empty stomach: Typically, ivermectin is taken on an empty stomach with a full glass of water unless directed otherwise by a doctor.
- Missed doses: If a dose is missed, take it as soon as you remember. If it\’s nearly time for the next dose, skip the missed dose and resume the usual schedule. Never double up doses.
- Storage: Store in a cool, dry place away from direct sunlight.
- Avoid alcohol: Alcohol can increase side effects or interfere with the action of the medication.
