Ivermectin

Ivermectin is a prescription antiparasitic medicine used for specific infections caused by susceptible parasites. This category includes human ivermectin tablets in different strengths, brands and pack quantities. The diagnosis and dose should be confirmed professionally because the correct amount is often calculated using body weight.

What Is Ivermectin Used For?

Recognised oral uses in certain countries include strongyloidiasis and onchocerciasis. Clinicians may also prescribe ivermectin for other parasitic conditions according to local guidance. Scabies treatment recommendations vary by country and patient circumstances.

Ivermectin does not treat bacterial infections, common viral illnesses or every type of parasite.

How Does Ivermectin Work?

Ivermectin binds to channels in susceptible parasites’ nerve and muscle cells. This causes paralysis and death of the parasite, allowing the body to clear the infection. Its selective action is different from that of antibiotics or antiviral medicines.

Available Strengths and Dosage

Human ivermectin tablets may be listed in several strengths. The required total dose depends on body weight, diagnosis and treatment schedule—not on the tablet strength alone. Some infections require a repeat dose or follow-up testing.

Never calculate a course simply by choosing a convenient strength. Use the number of tablets and timing supplied by the prescriber.

Side Effects and Precautions

Possible effects include nausea, diarrhoea, dizziness, weakness, itching and rash. Reactions can sometimes occur as parasites die. Urgent assessment is required for severe skin reactions, facial swelling, confusion, seizures or difficulty walking.

Tell the clinician about pregnancy, breastfeeding, liver problems, travel history and medicines such as warfarin. Veterinary ivermectin must never be used by humans because its concentration and ingredients may be unsafe.
