Ivermectin tablets come in several strengths, and knowing which one to use is a clinical decision, not a shopping decision. This guide explains what the strengths mean and what to ask a pharmacist or prescriber.
Why strength matters
Strength tells you how many milligrams of ivermectin are in each tablet. That matters because how the medicine is used depends on the specific condition being treated, the person's body weight, and other individual factors.
A strength that is right for one person may not suit another. That is why a prescriber or pharmacist decides, not the buyer.
Strengths available in the US
The most commonly dispensed strength at pharmacies selling ivermectin in the US is 3 mg. It matches the dosage of Stromectol, the FDA-approved US brand.
Higher-strength tablets (6 mg, 12 mg, 24 mg) are sold by some pharmacies, generally requiring a prescription. Compounded forms are also available through certain compounding pharmacies, again with a prescription.
The Iverheal tablets on this site come in 3mg, 6mg, 12mg and 24mg strengths. All require a valid prescription from a licensed US prescriber.
What drives the choice
For the FDA-approved uses, the labeled dosing guidance is weight-based. That means:
- Two people prescribed the same number of tablets may need different amounts based on weight.
- A prescriber who knows your weight, health history and the condition being treated picks the strength and number of tablets.
Do not choose a strength based on price alone. Do not use a strength or quantity prescribed for someone else.
Questions to ask your prescriber or pharmacist
Before you fill a prescription or place an order:
- Which strength did my prescriber specify, and why?
- How many tablets is my prescription for?
- Does my weight or any health condition affect the right amount?
- Do any of my current medicines interact with ivermectin?
- When should I take it and with or without food?
The last question on timing is for your pharmacist or the product label — not something we can answer here.
If you're in a pharmacist-dispensing state
In the seven states where pharmacists can dispense ivermectin without a doctor's prescription, the pharmacist makes the determination on what to dispense. They ask about your health history, other medicines and other factors as part of that review. See our state guide for which states these are and how each law works.
Strengths and the products we sell
Iverheal 3, 6, 12 and 24 contain 3mg, 6mg, 12mg and 24mg of ivermectin per tablet. All require a valid prescription from a licensed US prescriber. See each product page for pack sizes and prices:
The takeaway
Strength is one part of a clinical decision. Talk to a prescriber who knows your situation, follow the instructions you receive, and read the product label.
Frequently asked questions
What strength of ivermectin is most commonly used?
3 mg is the most commonly dispensed oral tablet in the US, matching the Stromectol brand. Higher strengths are available by prescription.
Who decides which strength I should take?
Your prescriber or pharmacist, based on the condition being treated, your body weight and your health history. It is a clinical decision, not a shopping choice.
What strengths do you sell?
Iverheal 3mg, 6mg, 12mg and 24mg. All require a valid prescription from a licensed US prescriber.
Can I order a higher strength because it seems like better value?
No. Use only the strength and quantity your prescriber specified. Using an incorrect dose can cause harm.
This article is general information, not medical advice. Oral ivermectin is a prescription medicine under US federal law, and only some states let pharmacists dispense it without an individual prescription. Talk to your doctor or pharmacist before using it.
