Quick Facts about Ivermectin
- Used to treat several types of parasitic infections, including onchocerciasis, lymphatic filariasis, and scabies.
- Works by paralyzing and killing parasites.
- Common forms include tablets and topical formulations.
- Typically well-tolerated with common side effects like nausea, dizziness, and diarrhea.
- Contraindicated in individuals with known allergies to ivermectin or its components.
- Important interactions with certain medications, such as blood thinners.
- Special caution is needed for use in pregnant or breastfeeding women.
- Seek urgent medical help if experiencing symptoms of a severe allergic reaction or overdose.
What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to invertebrate muscle and nerve cells, leading to paralysis and death of parasites. This process is specific to certain parasites and is generally safe for humans at prescribed doses. Selectivity is due to differences in the drug target site between humans and parasites.
Indications / Uses
Primarily, ivermectin is indicated for treating parasitic infections such as:
- Onchocerciasis (river blindness): Used especially in areas where the disease is endemic.
- Strongyloidiasis: An intestinal infection caused by the parasite Strongyloides stercoralis.
- Lice and scabies: Used topically for infestations.
While some have proposed ivermectin for COVID-19 treatment, current evidence does not support its effectiveness, and its use for this purpose remains controversial and off-label, necessitating professional medical consultation.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in multiple forms, including oral tablets and topical creams or lotions. Dosage depends on the specific condition treated and patient factors, such as weight and the presence of comorbidities. Typical administration is a single or multiple oral doses, based on the body weight for certain conditions. Professional assessment is crucial, particularly involving pregnant women, children, or people with liver issues.
How to Take It Correctly Step-by-Step
- Always follow the dosing instructions on the prescription label or from your healthcare provider.
- Take ivermectin on an empty stomach, at least one hour before a meal.
- If a dose is missed, take it as soon as remembered unless it is near the time for the next dose. Never double-dose to make up for a missed dose.
- Store the medication at room temperature, away from excess heat and moisture.
- Do not consume alcohol while taking ivermectin, as this may enhance side effects or interactions.
