Ivermectin: What It Really Does and How to Use It Safely

Ivermectin has been used for decades to treat parasitic infections in humans. It appears on the World Health Organization’s list of essential medicines because it reliably treats conditions like river blindness, strongyloidiasis, and scabies when prescribed correctly. Because it is cheap and widely available, people sometimes see claims online that it cures other illnesses — that's risky.

Ivermectin works by targeting nerve and muscle cells in many parasites, causing paralysis and death of the parasite. That mechanism makes it safe for humans at the right dose, but safety depends on correct dosing, the right formulation, and a proper diagnosis.

What it's used for

Doctors prescribe ivermectin for several parasitic infections and some skin conditions; the exact use depends on the disease and local guidelines. Topical forms treat scabies and rosacea in certain cases, while tablets treat intestinal parasites and river blindness.

How to buy safely

Always get a prescription before you buy. Legitimate pharmacies will ask for one. Avoid products labeled for animals — formulations and doses differ and veterinary products can be dangerous for people. When buying online check for a physical address, clear contact details, and pharmacy licensing or accreditation. Look for HTTPS on the site, read independent reviews, and compare prices — extremely low prices are a warning sign.

If a site offers fast shipping without a prescription, sells via social media DMs, or pressures you to buy quickly, walk away. If you have liver disease, are pregnant, breastfeeding, or take many other medicines, talk to your doctor before using ivermectin.

Side effects are usually mild — nausea, dizziness, diarrhea, and rash — but stop the drug and get help if you have trouble breathing, swelling, fainting, or severe confusion. For COVID-19, major health organizations recommend using ivermectin only in clinical trials; evidence does not support routine use and self-treatment has caused harm.

If you suspect an adverse reaction, stop the drug and contact emergency services for severe symptoms or call your healthcare provider for milder ones.

For travel or tropical medicine concerns, ask clinics that specialize in infectious disease. Accurate treatment starts with a correct diagnosis and a provider who follows local guidelines.

If you’re unsure where to begin, start by asking your primary care doctor or a pharmacist to review any information you found online. Safe treatment takes trusted advice. Keep records and speak up if something feels wrong, act promptly.
