Ivermectin 3mg vs 6mg vs 12mg: Why Different Strengths Exist

People searching for "ivermectin 12mg" often expect to find a 12mg tablet on a US pharmacy shelf. There isn't one. The FDA-approved product, branded or generic, comes in one oral strength: 3mg. The 6mg, 12mg and 24mg tablets you see online are made by manufacturers outside the US, such as Healing Pharma in India, which sells them as Iverheal. Some US pharmacies also compound higher-strength capsules for a specific prescription. Here's how the strengths fit together.

Why the dose depends on weight

Ivermectin isn't a one-size tablet. The dose a prescriber chooses depends on body weight and on the infection being treated, and some infections need a second dose later. So two adults with the same diagnosis can be told to take a different number of tablets.

That's the whole reason higher strengths exist. The total amount of ivermectin is what matters, not how it's split into pills. Please don't work out a dose yourself from a chart online. Your prescriber sets it, and the label explains how to take it.

The FDA-approved 3mg tablet

Stromectol from Merck and its FDA-approved generics are 3mg tablets. This is the product the state pharmacist-dispensing laws in places like Texas and Tennessee are written around. Our ivermectin OTC guide explains what those laws allow.

Iverheal 3, 6, 12 and 24

Iverheal is ivermectin made in India by Healing Pharma, in 3mg, 6mg, 12mg and 24mg tablets sold in strips of 10. It is not FDA-approved in the US. It's what we sell, and every order needs a valid prescription from a licensed US prescriber, in every state, including states with a pharmacist-dispensing law.

• Iverheal 3: 3mg tablets
• Iverheal 6: 6mg tablets
• Iverheal 12: 12mg tablets
• Iverheal 24: 24mg tablets

Compounded capsules

Compounding is when a licensed pharmacy prepares a medicine to a prescriber's order, for example by putting a set amount of ivermectin into a capsule. Prescribers sometimes choose it to cut the number of pills, avoid an inactive ingredient a patient can't tolerate, or match a dose that doesn't divide neatly into 3mg tablets. Compounded medicines aren't FDA-approved products either, so they always need a prescription and are prepared for a named patient. We don't sell compounded capsules.

Side by side

| | FDA-approved 3mg tablet | Iverheal tablets | Compounded capsules | |---|---|---|---| | Strengths | 3mg | 3mg, 6mg, 12mg, 24mg | Whatever the prescriber orders | | FDA-approved | Yes | No | No | | Prescription | Yes, except where a state dispensing law applies | Yes, in every state | Yes, in every state | | Made by | Merck and US generic makers | Healing Pharma, India | A compounding pharmacy, per prescription |

Are higher strengths stronger or riskier?

Not in themselves. One 12mg tablet and four 3mg tablets contain the same 12mg. The risk comes from the total dose relative to your weight and health, which is why the screening and the prescriber's judgment matter more than the strength printed on the pack. Our side effects and interactions guide covers what to watch for at any strength. The National Library of Medicine's MedlinePlus entry is a good neutral summary too.

What does "not FDA-approved" mean for you?

It means the FDA hasn't reviewed that specific product's manufacturing, labeling or data for the US market. It's worth knowing before you buy, and a seller should tell you plainly. Our comparison of Stromectol and generic ivermectin explains how approved generics differ from products made for other markets. If you'd rather stay with an FDA-approved 3mg product, your prescriber can send that prescription to a local pharmacy.

Questions to ask your prescriber

If you're deciding between strengths, it's worth asking:

• What total dose do I need, and is it a single dose or more than one?
• Would a higher-strength tablet cut the number of pills enough to matter?
• Do I have any allergies to inactive ingredients that affect the choice?
• Would you rather I use an FDA-approved product, and will my insurance cover it?

The answers usually make the choice obvious.

How the prescription reaches us

Your prescriber can send the prescription to us, or you can add it at checkout. A pharmacist reviews the prescription and your health questionnaire before anything ships, and your card is charged only after approval. Our questions page and frequently asked questions cover the practical steps, and you can reach us through the contact page.

Storage

Keep tablets at room temperature in their original strip or container, away from moisture, and check the expiry date on the pack before use.

A note on splitting tablets

People sometimes ask whether they can split or crush tablets to get a different amount. Don't change how you take them unless your prescriber or pharmacist tells you to. The label and the instructions on your pack are what to follow. Keep a note of what you took and when, especially if a second dose is planned, so you can answer accurately if you have questions later.

Which one is right for you?

That's a question for your prescriber. If you don't have a prescription yet, read how to get ivermectin for the doctor and telehealth routes. Every order with us needs a prescription and a pharmacist's review, and your card isn't charged until it's approved.
