What Are Ivermectin 12mg Tablets?
Ivermectin 12mg tablets are a higher-strength formulation of the FDA-approved antiparasitic medication ivermectin. Each tablet contains exactly 12 milligrams of pharmaceutical-grade ivermectin as the active ingredient, making it the most convenient single-tablet dosing option for average-weight adults.
The 12mg strength has become the most popular ivermectin formulation due to its dosing convenience — a single tablet approximates the standard 200 mcg/kg dose for adults weighing 55-70 kg (121-154 lbs). This eliminates the need to take multiple 3mg tablets, reducing dosing errors and improving compliance.

Frequently Asked Questions
What is ivermectin 12mg used for?
Ivermectin 12mg tablets are used to treat parasitic infections including strongyloidiasis (intestinal roundworm), onchocerciasis (river blindness), scabies, and head lice. The 12mg strength provides convenient single-tablet dosing for adults weighing approximately 55-70 kg (121-154 lbs) at the standard 200 mcg/kg dose.
Is 12mg of ivermectin too much?
For adults weighing 55-70 kg, a single 12mg tablet is within the standard therapeutic dose range (200 mcg/kg). For lighter individuals (under 55 kg), 12mg may exceed the recommended dose, and smaller 3mg tablets would allow more precise dosing. Always follow your healthcare provider's specific dosage instructions.
How many 12mg ivermectin tablets should I take?
Most adults in the 55-70 kg weight range need just one 12mg tablet as a single dose. Heavier individuals may need additional supplementation (e.g., 12mg + 3mg). The exact number depends on your weight, condition being treated, and your healthcare provider's instructions. Never take more than prescribed.
Can I split a 12mg ivermectin tablet?
Some 12mg tablets have a score line allowing them to be split in half (6mg each). However, splitting unscored tablets can result in uneven dosing. If you need a dose lower than 12mg, it is better to use 3mg tablets for accurate dosing. Consult your pharmacist about whether your specific tablet is designed to be split.
Where can I buy ivermectin 12mg tablets?
Ivermectin 12mg tablets are available through our recommended source, Doctor B Ivermectin 12mg at Tymurs Supplement, with GMP certification and third-party lab testing. They are also available through select online pharmacies, telehealth-partnered pharmacies, and international pharmacy sources. Always verify the authenticity and licensing of any seller.
What is the difference between ivermectin 12mg and 3mg?
The only difference is the amount of active ingredient per tablet. Both contain pharmaceutical-grade ivermectin. The 12mg tablet offers convenience (one tablet per dose for most adults), while 3mg tablets offer precision (adjustable in 3mg increments). The 3mg strength is more widely available in U.S. pharmacies and more likely to be covered by insurance.
