What It Is and How It Works
Ivermectin is an antiparasitic medication effective against a range of parasitic infections. It works by binding to certain chloride ion channels in the nerve and muscle cells of parasites, increasing permeability, leading to paralysis and death of the parasite.
Technically, ivermectin increases chloride ion influx across cell membranes, resulting in hyperpolarization and paralysis of parasites, effectively eliminating them from the host\’s body.
Indications / Uses
Ivermectin is primarily utilized for treating parasitic infections such as onchocerciasis (river blindness), strongyloidiasis, and other conditions caused by roundworms. It also treats ectoparasitic infestations like lice and scabies.
Off-label uses include potential antiviral applications, which are still a subject of clinical trials and investigation. These uses should only be considered under strict medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including tablets, topical lotions, and oral solutions. The dosing depends on the condition being treated, the patient\’s weight, and whether the parasite is internal or external.
The typical education-based dose for strongyloidiasis in adults is a single oral dose that may require adjustment based on body weight, but patients should strictly adhere to the prescribed regimen by their healthcare provider.
How to Take It Correctly Step-by-Step
The following general steps should be taken when administering ivermectin:
- Follow prescribed dosage instructions carefully.
- Take oral forms on an empty stomach, at least 1 hour before or 2 hours after a meal, with a full glass of water.
- For missed doses, take as soon as remembered unless it’s near the time for the next dose. Do not double doses.
- Store the medication in a cool, dry place away from light and out of reach of children.
Avoid mixing with alcohol or grapefruit juice, as these can induce adverse effects or interactions.
Side Effects Common to Serious
Common Side Effects
Common side effects include headache, dizziness, nausea, fever, joint pain, and fatigue. These are typically mild and resolve on their own.
Less Common Side Effects
Some patients may experience pruritus (itching), skin rash, or swelling of the lymph nodes.
Serious or Rare Side Effects
Serious side effects, though rare, require immediate medical attention and include signs of allergic reactions like rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.
Contraindications & Precautions
Ivermectin should not be used by individuals with a known allergy to ivermectin or similar medications. It must be used cautiously in patients with liver impairment or who are immunocompromised. Pregnant or breastfeeding women should consult with their healthcare provider before use.
Drug, Food, and Supplement Interactions
Ivermectin can interact with blood thinners (anticoagulants), anticonvulsives, and certain antibiotics, potentially altering the effectiveness of either drug. Patients should disclose all medications, including OTC products and supplements, to their healthcare provider.
Consumption of alcohol or grapefruit can enhance certain side effects of ivermectin, thus are best avoided.
Price & Availability
