What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to a class of drugs known as avermectins. It works by binding to invertebrate muscle and nerve cells of parasites, causing paralysis and death, or preventing parasites from reproducing. In technical terms, it acts on glutamate-gated chloride channels found in nerve and muscle cells of invertebrates, disrupting nerve impulses.
Indications / Uses
The primary approved uses of ivermectin include treatment of infections caused by certain parasites:
- Onchocerciasis: Commonly known as river blindness, it is treated with ivermectin because of its effectiveness in killing microfilariae.
- Strongyloidiasis: An intestinal infection caused by Strongyloides stercoralis, where ivermectin is a standard treatment.
Additionally, ivermectin is used off-label for conditions like scabies and head lice in some cases. Such off-label uses should be pursued only under the guidance of a healthcare professional, as their appropriateness can vary depending on specific patient circumstances and regional regulatory guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including:
- Oral tablets: Typically used for parasitic infections.
- Topical formulations: Available for skin applications for conditions like rosacea and certain types of lice.
The dosing of ivermectin will depend on various factors, including the type of infection being treated, patient weight, liver and kidney function, and other concurrent medical conditions. It is critical for patients to follow prescription instructions exactly as provided by their healthcare professionals.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach, about 1 hour before a meal.
- If you forget a dose, take it as soon as remembered, but skip it if it’s near the time of your next dose. Do not double doses.
- Store ivermectin at room temperature away from moisture and heat.
Avoid mistakes such as taking multiple doses to make up for a missed one, or stopping treatment early without your doctor\’s advice, as this might affect the effectiveness of the treatment.
Side Effects Common to Serious
Side effects of ivermectin can vary from mild to severe:
- Common: Mild dizziness, nausea, diarrhea, tiredness.
- Less common: Skin rash or mild itching.
- Serious: Allergic reactions (rash, itching/swelling, severe dizziness, trouble breathing), which require immediate medical attention.
Contraindications & Precautions
Ivermectin is not suitable for everyone. Contraindications include:
- Pregnancy: Use only if absolutely necessary and prescribed by a clinician.
- Breastfeeding: May pass into breast milk; consult with a doctor.
- Allergies: Avoid if there\’s a known allergy to ivermectin or similar drugs.
- Liver/Kidney Disease: Requires special caution and professional advice due to potential accumulation and side effects.
Drug, Food, and Supplement Interactions
Ivermectin can interact with other medications, such as:
- Medicines that affect liver enzymes could alter ivermectin clearance.
- Interactions with other heavily protein-bound drugs.
- Avoid alcohol, as it may exacerbate certain side effects like dizziness.
Patients should inform their doctor about all current medications, including over-the-counter drugs, herbal supplements, and vitamins.
