Ivermectin 24 mg

Description

Do ivermectin 24mg tablets actually exist?

The illustrative pharmacist: “Not as a licensed medicine anywhere we could find. When a strength is approved, it has a label in a public database. I start with DailyMed, the US National Library of Medicine’s library of package inserts. Every human ivermectin tablet there, brand and generic, is a 3 mg tablet. That includes Stromectol from Merck and the generics from several makers. There is no 6, 12 or 24 mg tablet in the US listings.”

“Outside the US, the picture widens a little. Indian pharmacies stock 6 mg and 12 mg ivermectin tablets, and those are prescription products, mainly used for scabies and worm infections. But when we searched Indian retail pharmacy catalogues and public regulator material for a 24 mg tablet, nothing came up. The only places that list ivermectin 24mg are bulk trading platforms and export catalogues. Those listings are offers to manufacture or ship, not proof that a health authority reviewed the product.”

“People also ask me about a 20 mg version. The same problem applies, and our separate guide to ivermectin 20 mg covers it. Here I’ll stick to 24 mg.”

Why does a missing licence matter if the drug is the same?

“Because a licence is the only thing that tells you the tablet holds what the box says. A regulator checks the amount of drug per tablet, how evenly it is spread and what the fillers are. Without that, a tablet marked 24 mg could hold 10 mg or 40 mg. For ivermectin, where the main danger is a large dose reaching the brain, that is a safety problem.”

So where does the number 24 come from?

“From arithmetic and marketing. Weight-based dosing can push a very heavy adult’s total into the twenties, and sellers package that total as one pill. Eight standard 3 mg tablets also add up to 24 mg, which makes the figure look familiar. Neither makes it a recognised product.”

How does a prescriber reach a dose for a large adult without an ivermectin 24mg tablet?

The illustrative pharmacist: “This is the most reasonable question behind most searches for ivermectin 24mg, so it deserves a clear answer. The US label does not give one fixed dose. It gives a dose per kilogram of body weight. For intestinal strongyloidiasis, it is about 200 micrograms per kilogram, usually as a single dose. For river blindness (onchocerciasis), it is about 150 micrograms per kilogram.”

“The Stromectol label on DailyMed includes a weight table that converts this into a number of 3 mg tablets for lighter patients. The table stops listing tablet counts at the top weight band. Above that band, the prescriber is told to work the figure out from the per-kilogram rate. That is where bigger totals appear.”

Can a weight-based total ever reach 24 mg?

“For a small number of people, yes. If you multiply the per-kilogram rate by the weight of a very heavy adult, the answer can land in the low-to-mid twenties. The prescriber then rounds to a number of standard tablets they can actually dispense. In the US that means several 3 mg tablets. In India it may mean a combination of 6 mg and 12 mg tablets. The person still takes a dose a doctor has worked out, from tablets a regulator has checked.”

“To be clear, I’m describing the arithmetic, not giving anyone a dose. The rate depends on the infection, some infections need repeat doses, and pregnancy, other medicines and travel history change the plan. Those are prescriber decisions, not figures to apply at home.”

Is a large total the same thing as a 24 mg tablet?

“No. A total built from licensed tablets comes with a known amount per tablet and a pharmacist who checked the weight. An ivermectin 24 mg tablet from an export listing has neither. Most adults weigh far less than the heavy patient that total assumes. So one such tablet can already be well above what their own prescriber would choose. If they take a second because the first ‘did nothing’, the dose climbs fast.”

If you already take ivermectin on prescription, the strength pages for the ivermectin 3 mg tablet, the ivermectin 6 mg tablet and the ivermectin 12 mg tablet explain each licensed strength. For help reading the dose line on your own bottle, see our guide to reading a prescription label; the label sections it walks through apply to most medicines.

What happens in the body when someone takes too much?

The illustrative pharmacist: “At normal doses, ivermectin mostly stays out of the human brain. A transport pump in the blood vessels of the brain pushes it back out. A very large dose can overwhelm that defence. So can other drugs that block the same pump, and so can rare genetic differences. Once enough ivermectin reaches the nervous system, the symptoms change from an upset stomach to something much more serious.”

What do the early signs look like?

“The first complaints are usually nausea, vomiting, stomach pain and diarrhoea, often with dizziness or headache. Some notice blurred vision, a racing heart or low blood pressure. On their own these are not specific, so we ask how much was taken and in what form.”

And the signs that mean the brain is involved?

“Confusion, drowsiness and unsteady walking are the warning signs. Doctors call poor coordination ataxia. We also see tremor, which families may describe as shaking, and sometimes hallucinations. The most serious cases involve seizures and a deepening loss of consciousness that can end in coma. The CDC health advisory from August 2021 listed this same range, from stomach upset through to central nervous system depression and seizures. The drug label also reports neurotoxicity, including deaths, after overdose.”

How fast does it happen?

“Two ways. In a report from the Oregon Poison Center, published as a letter in the New England Journal of Medicine in October 2021, most people who became ill did so within about two hours of one large first dose. A smaller group got worse slowly over several days or weeks of repeated doses. If you see confusion, poor balance or dizziness after repeated doses, treat it as a possible overdose and call Poison Help.”

Is there an antidote?

“No. Hospital care is supportive: fluids, blood pressure support, breathing support and seizure control while the drug clears. That is why we push for an early call. A poison specialist can tell you whether to watch at home or go to the emergency department.”

What you notice	What it can mean	What to do
Nausea, vomiting, loose stools, mild dizziness after a prescribed dose	Common side effects at label doses	Call your prescriber or pharmacist if they persist or worry you
Same symptoms after a 24 mg or other unlicensed tablet, or an animal product	Possible early toxicity	Call Poison Help, 1-800-222-1222, now
Confusion, unusual sleepiness, unsteady walking, tremor, hallucinations	Drug may be affecting the brain	Call Poison Help or go to the emergency department; do not wait to see if it passes
Seizure, cannot be woken, trouble breathing, collapse	Medical emergency	Call 911

Why did poison centers see a spike in ivermectin calls in 2021?

The illustrative pharmacist: “Two things rose together: demand for ivermectin as a COVID-19 remedy and the use of products never meant for people. CDC tracked both. By mid-August 2021, US outpatient prescriptions for ivermectin had climbed about 24-fold above the pre-pandemic weekly average. Over the same months, poison center calls about people exposed to ivermectin rose too. They were three times the usual level in January 2021 and five times higher by July.”

What role did animal products play?

“A big one. Livestock ivermectin comes as horse pastes, sheep drenches, cattle injectables and pour-ons, sized for animals weighing hundreds of kilograms, sometimes with ingredients never tested in people. CDC’s advisory described an adult who drank an injectable cattle product. In the Oregon report, most of the people who called had bought veterinary ivermectin.”

Is it still happening?

“Calls fell after 2021, but interest stayed. Since 2025 several US states have passed laws letting pharmacies hand out ivermectin without an individual prescription. Federal law still treats the tablets as prescription-only, and the state changes did not create any new tablet strength. Poison centers still get calls, now often linked to cancer claims online. A news report in 2026 described a teenager with advanced bone cancer who needed emergency care for neurotoxicity after taking ivermectin without a prescription. If you or someone at home keeps any medicine in bulk, our guide to keeping medicines away from children and visitors covers locked storage and counting tablets.”

How can I tell an ivermectin 24mg listing is unreliable?

The illustrative pharmacist: “The strength itself is the first warning. A product page selling ivermectin 24mg tablets is offering something no regulator we checked has approved. After that, I look for a cluster of other signs.”

What does a legitimate source look like instead?

“It asks for a valid prescription, names the maker, shows a batch and expiry, and sells only strengths that match a published label. Our guide on how medicines move from manufacturer to patient explains the supply chain in plain terms. If you want to know how this site handles prescriptions, the answer page on whether NewLifeMedix is legitimate sets that out.”

What if I already ordered a 24 mg product?

“Do not take it, and do not try to cut it into what you think is a normal dose. You cannot know how evenly the drug is spread through an unlicensed tablet. Skip to the section below on tablets you already have.”

Which conditions is ivermectin actually used for?

The illustrative pharmacist: “In the US, the oral tablet has two FDA-approved uses. Doctors also use it off-label for a few other conditions, based on public health guidance.”

The two approved uses

• Intestinal strongyloidiasis. This is an infection with the threadworm Strongyloides stercoralis, picked up through the skin from contaminated soil. CDC names ivermectin as the first-choice treatment, with albendazole as the alternative. You can read the CDC clinical guidance for strongyloidiasis. Our albendazole 400 mg page covers that alternative. People who need steroids or other drugs that weaken the immune system may be screened or treated first, because the infection can spread through the body.
• Onchocerciasis (river blindness). This is a worm infection spread by blackflies in parts of Africa and Latin America. Ivermectin kills the young worms (microfilariae) but not the adults, so repeat doses months apart are common.

Common off-label uses

• Scabies. Oral ivermectin is not FDA-approved for scabies, but CDC’s scabies treatment guidance includes it. Usual scabies needs two doses given a week or two apart. Crusted scabies needs more doses plus a cream. This is the main reason 6 mg and 12 mg tablets are common in India.
• Head lice. A prescription ivermectin lotion is FDA-approved for head lice. Oral tablets are sometimes used off-label when other treatments fail. Our article on getting rid of head lice covers combing and household steps that go alongside medical treatment.
• Some other worm infections. MedlinePlus notes that ivermectin is sometimes used for other roundworm infections. The MedlinePlus ivermectin page also covers side effects and what to do in an overdose.

Who needs extra care?

“The label says ivermectin should not be used in pregnancy because safety has not been shown. CDC lists pregnancy and breastfeeding as relative reasons to avoid it, along with a body weight under 15 kg. If you are pregnant or planning to be, our general guide on medicines during pregnancy covers questions to raise with your prescriber. If you are nursing, see medicine use while breastfeeding. Anyone who has lived in or travelled to parts of West or Central Africa where the Loa loa eye worm is found needs checking first. Heavy Loa loa infection can lead to a serious brain reaction after treatment.”

“Older adults, people with liver disease and people on many medicines need a careful review, since ivermectin is broken down in the liver. See how the liver breaks down medicines. The guide to medicine safety with liver disease lists questions to ask. For drug combinations, the drug interaction overview shows how pharmacists screen a medicine list. The page on medicines in older adults explains why age changes how drugs are handled.”

What did trials find on COVID-19 and cancer?

The illustrative pharmacist: “I get this question more than any other, so here is what the best evidence says. Ivermectin is not approved for COVID-19 or for any cancer. Large, well-run trials in COVID-19 found no meaningful benefit. For cancer, the evidence is still at the lab-dish stage.”

COVID-19

• TOGETHER trial (NEJM, 2022). Adults with early COVID-19 in Brazil got ivermectin at 400 mcg/kg a day for three days, or a placebo. Hospital care or a long emergency department stay happened in 14.7% of the ivermectin group and 16.3% of the placebo group. The gap was not statistically significant.
• ACTIV-6 higher-dose arm (JAMA, 2023). This US trial tested a target of 600 mcg/kg a day for six days, about three times the usual single dose. In 1,432 outpatients, median time to recovery was 11 days with ivermectin and 12 with placebo. The analysis showed no real treatment effect, and hospital visits and admissions were no lower. You can read the ACTIV-6 ivermectin results in JAMA.
• Guideline bodies. In March 2021 the World Health Organization advised using ivermectin for COVID-19 only within trials. The US COVID-19 Treatment Guidelines Panel recommended against it outside trials.

“Notice the ACTIV-6 dose. Researchers already tested a high, repeated dose, under medical supervision, and it still didn’t help. An ivermectin 24mg tablet bought online doesn’t add a benefit those trials missed. It only adds risk.”

Cancer

“Some lab studies found that ivermectin can harm cancer cells in a dish. That is an early, common finding; many compounds do the same. In early 2026 the National Cancer Institute said it was running a preclinical study, which means lab research, not testing in patients. KFF Health News reported that there is still no evidence it is safe and effective for cancer in people. A small trial in one type of metastatic breast cancer found no clear benefit from adding it to immunotherapy. If you are living with cancer and are curious about it, raise it with your oncologist. Ivermectin can interact with other drugs, and high doses can cause the brain effects described above. Our piece on talking openly with your doctor about a medicine has tips for starting that conversation.”

“The same goes for ‘detox’ and ‘parasite cleanse’ claims: there is no evidence for them. Similar claims circulate about an animal dewormer, which our page on fenbendazole and people looks at. For evidence-based everyday habits, our health tips section is a better place to start.”

What should I do with ivermectin 24mg tablets I already bought?

The illustrative pharmacist: “Start by deciding whether anyone has taken them.”

If someone has taken one

1. Check for danger signs: seizure, collapse, trouble breathing or not waking up. If any are present, call 911.
2. Otherwise, call Poison Help at 1-800-222-1222, even if the person feels fine. Delayed symptoms are possible.
3. Tell them the strength printed on the pack, how many tablets were taken, when, and the person’s weight.
4. Mention any other medicines, especially new ones. Our step-by-step piece on what to do right after an accidental extra dose shows the kind of information to gather before you call.

If nobody has taken them

• Do not take them, and do not give them to anyone else, including pets. Animal doses are set by a veterinarian for that animal.
• If you have a real infection to treat, see a prescriber. They can confirm the diagnosis and prescribe licensed tablets at the right dose.
• Get rid of them safely. A pharmacy take-back point is best. Our guide to disposing of unused medicines covers take-back sites and the household-trash method for when no take-back is nearby.
• Until then, keep them locked away from children. The safe medicine storage guide lists simple steps.
• If the product looked fake or made you ill, you can report it to the FDA’s MedWatch program and tell your prescriber.

If you were prescribed ivermectin and the dose confuses you

“Call the pharmacy that filled it. Ask them to confirm the number of tablets, how many doses and the timing. Weight-based doses often mean several tablets at once, and that can look alarming. The pharmacist can check the math against your weight. For a general walk-through of the leaflet that comes with a prescription, see how to read a medication guide. If you are taking ivermectin for a travel-related infection, the planning tips in travelling with prescription medicines still apply.”

Frequently asked questions about ivermectin 24mg

Is there a 24 mg ivermectin tablet?

Not as a licensed product in any regulator listing we checked. US ivermectin tablets are 3 mg, and India sells 6 mg and 12 mg on prescription. An ivermectin 24mg tablet appears only on wholesale and export listings that have not been through a medicines regulator’s review.

How is ivermectin dosed by weight?

The US label sets the dose per kilogram of body weight, and the rate depends on the infection. The prescriber works out the total and turns it into a number of licensed tablets. This is a prescriber calculation, not something to work out at home.

How much ivermectin is too much?

There is no safe self-chosen amount. The right dose depends on the infection and your weight, and your prescriber works it out from the label. Taking more than prescribed, repeating doses without advice, or using an animal product can all cause toxicity. If you have taken more than prescribed, call Poison Help at 1-800-222-1222.

What are the symptoms of ivermectin toxicity?

Early signs include nausea, vomiting, diarrhoea, dizziness, headache and blurred vision. More serious signs are confusion, sleepiness, poor balance, tremor, hallucinations, low blood pressure, seizures and coma. Symptoms can appear within hours of one large dose, or build up over days of repeated doses.

Can people take horse or cattle ivermectin?

No. Animal products are made for animals weighing hundreds of kilograms. They can be highly concentrated and may contain ingredients not tested in people. In 2021, they caused many of the poisonings reported to US poison centers.

What strengths does ivermectin come in?

Oral tablets are 3 mg in the US. India also sells 6 mg and 12 mg tablets. Topical ivermectin comes as a lotion for head lice and a cream for rosacea, which are separate products from the tablets.

Does ivermectin work for COVID-19?

Large randomised trials, including TOGETHER and ACTIV-6, found no meaningful benefit, even at higher, repeated doses. WHO and US guideline panels do not recommend it for COVID-19 outside research.

Is ivermectin a treatment for cancer?

No. It is not approved for any cancer. Lab studies are early, and the small human data so far shows no clear benefit. Talk to your oncologist before adding any medicine to cancer treatment.

Key takeaways

• No regulator we checked lists an ivermectin 24mg tablet. Licensed oral strengths are 3 mg in the US and 6 mg and 12 mg in India.
• Ivermectin is dosed by weight. A very heavy adult’s total can reach the twenties, but a prescriber builds that from standard tablets.
• Too much ivermectin can affect the brain, causing confusion, poor balance, seizures and coma. There is no antidote.
• In 2021, poison center calls rose sharply, driven largely by people using animal ivermectin to try to prevent or treat COVID-19.
• Approved uses are strongyloidiasis and river blindness. Scabies and lice are common off-label uses under medical care.
• Trials found no benefit for COVID-19. There is no human evidence that it treats cancer.
• If you bought a 24 mg tablet, don’t take it. Call Poison Help (1-800-222-1222) if anyone has, and call 911 for seizures, collapse or breathing trouble.

If you searched for ivermectin 24mg, here is the short answer. No medicines regulator we checked lists a 24 mg ivermectin tablet. In the US, the only licensed oral tablet is 3 mg. In India, 6 mg and 12 mg tablets are sold on prescription. The 24 mg figure turns up on bulk-export and wholesale sites, not in drug databases.

Ivermectin is a useful drug for certain worm and mite infections. The trouble starts when one tablet carries several times the usual amount, or when people take it for things it does not treat.
