Ivermectin is a drug that fights parasites. It started out as a treatment for livestock and later became a staple for human infections like river blindness and scabies. The medicine works by paralyzing tiny bugs, so they can’t survive inside the body. Because it targets a specific nerve pathway that humans don’t have, it’s usually safe when you follow the right dosage.
Most people hear about ivermectin for two main reasons: treating skin problems caused by mites and killing parasites that live in the bloodstream. Doctors also prescribe it for strongyloidiasis, a gut worm infection, and for onchocerciasis, the disease that can cause blindness in parts of Africa. The typical dose for an adult is 200 micrograms per kilogram of body weight, taken as a single tablet. For a 70‑kg person, that works out to around 12 mg.
If you’re using a generic version, the pill strength might be 3 mg, 6 mg, or 12 mg, so you’ll need to count the tablets to hit the right total. Children get a lower dose based on their weight, and the drug isn’t recommended for infants under 15 kg. Always ask a pharmacist to double‑check the calculation before you start.
When you take ivermectin as prescribed, serious problems are rare. The most common side effects are mild and go away on their own: headache, dizziness, nausea, or a rash around the bite site. If you notice severe itching, swelling, or trouble breathing, stop taking the medicine and call a doctor right away – those could be signs of an allergic reaction.
One mistake people make is using the veterinary formulation meant for animals. Those doses are far stronger and can lead to dangerous toxicity. Stick to the human‑grade tablets you get from a licensed pharmacy. Also, don’t mix ivermectin with drugs that affect the liver’s enzyme system, like certain anti‑seizure meds, unless your doctor says it’s okay.
Pregnant or breastfeeding women should only use ivermectin if the benefits outweigh the risks, because safety data are limited. Talk to your healthcare provider if you’re unsure. Finally, keep the medication out of reach of kids and store it in a cool, dry place.
In short, ivermectin is a powerful tool against many parasitic infections, but it works best when you use the right dose, get it from a reputable source, and watch for any unusual symptoms. If you follow these simple steps, the drug can help you get back to feeling normal without a lot of hassle.
