Ivermectin: What It Is, When It Works, and How to Use It Safely

If you’ve typed ‘ivermectin’ into a search bar this year, you probably saw headlines about COVID, pets, and a lot of controversy. Let’s cut through the noise and give you the basics you actually need.

Ivermectin is a drug that started out as a veterinary dewormer. In humans it’s approved for a handful of parasitic infections – for example, river blindness (onchocerciasis), strongyloidiasis, and scabies. Those are the situations where the FDA and most health agencies say it’s safe and effective.

Dosage and Who Should Avoid It

When a doctor prescribes ivermectin for an approved infection, the dose is usually based on your weight. A common adult dose for onchocerciasis is a single 150‑200 µg/kg oral tablet. For strongyloidiasis the regimen can be a single dose or a short three‑day course. The key is you follow the exact amount your prescriber writes down – taking more won’t make it work faster and can raise the risk of side effects.

People with a history of allergic reactions to ivermectin, pregnant women, and those with certain liver conditions should avoid it unless a doctor says otherwise. Common side effects are mild: headache, dizziness, nausea, or a rash. Serious reactions are rare but can include low blood pressure or vision changes, so seek medical help if you notice anything odd.

Buying Ivermectin Online – Do It Right

Because the drug got a lot of buzz, you’ll find many sites that claim to sell it without a prescription. That’s risky. The safest route is to get a legitimate prescription from a licensed provider and fill it at a certified pharmacy – whether that pharmacy is brick‑and‑mortar or an online service that verifies prescriptions.

If you do use an online pharmacy, check these three things: the site shows a physical address, it requires a prescription, and it’s accredited by a recognized pharmacy board (look for a seal from the National Association of Boards of Pharmacy or similar). Avoid “buy now, no prescription” offers – they’re often counterfeit or the wrong formulation (like a veterinary version that’s not meant for people).

Once you have the medication, store it at room temperature, away from moisture, and keep it out of reach of children. Don’t split tablets unless your doctor says it’s okay; breaking them can affect how the drug is absorbed.

Bottom line: ivermectin works well for the infections it’s approved for, but using it for anything else should only happen under direct medical supervision. If you’re unsure whether ivermectin is right for you, ask your doctor for a clear explanation and don’t rely on social media posts alone.

Got more questions? Common ones include:

• Can ivermectin stop COVID? Current clinical guidelines say there’s no solid evidence for that use, and major health agencies advise against it outside a trial.
• Is a single dose enough? It depends on the infection – some need one dose, others need a short course.
• Can I take it with other meds? Ivermectin can interact with some blood thinners and anti‑seizure drugs, so list all your medicines for your prescriber.

Stay informed, follow professional advice, and you’ll get the most benefit from ivermectin without unnecessary risk.
