If you’ve searched for ivermectin tablets or tried to buy ivermectin online, you’ve probably noticed the same active ingredient sold under several different brand names — Ivanorm, Iverheal, Iverjohn, and Ivercen. All four are manufactured in India and are popular choices for people researching ivermectin for humans, but they’re not identical products. They differ in available strengths, pricing, manufacturer, and global distribution.
This guide compares all four brands side by side — strengths, pricing, efficacy, side effects, and dosing — so you can make an informed decision before you buy ivermectin tablets online. (Looking for current pricing instead? Jump straight to our ivermectin price comparison page.)
Why Ivermectin Matters
Ivermectin is one of the most widely used antiparasitic medicines in the world. First approved for human use in 1987, it sits on the WHO List of Essential Medicines and is used by more than 250 million people every year to treat parasitic conditions such as scabies, river blindness (onchocerciasis), and strongyloidiasis.
In India — often called “the pharmacy of the world” — ivermectin tablets are manufactured under dozens of brand names. Four of the most searched and most exported are:
- Ivanorm (3mg, 6mg, 12mg)
- Iverheal (3mg, 6mg, 12mg)
- Iverjohn (3mg, 6mg, 12mg)
- Ivercen (12mg only)
All four contain the same active ingredient, Ivermectin IP/USP, but the manufacturer, packaging, pricing, and export availability vary. This guide breaks down every important difference. You can browse the full range of ivermectin tablets — including these brands — on our ivermectin category page.
What Is Ivermectin? A Quick Medical Overview
Before comparing brands, it helps to understand what ivermectin is, how it works, and why it’s trusted by clinicians worldwide.
Active ingredient and drug class
| Generic name | Ivermectin |
| Drug class | Macrocyclic lactone / Anthelmintic / Ectoparasiticide |
| Discovered | 1975, by Satoshi Ōmura and William Campbell (Nobel Prize, 2015) |
| Approved for human use | 1987 |
| WHO status | Essential Medicine |
| FDA-approved uses | Strongyloidiasis (intestinal), onchocerciasis (river blindness), head lice (topical), rosacea (topical cream) |
How ivermectin works
Ivermectin binds selectively to glutamate-gated chloride ion channels found in the nerve and muscle cells of parasites. This causes an influx of chloride ions that paralyzes and ultimately kills the parasite. These channels don’t exist in the same form in mammals, and ivermectin doesn’t easily cross the human blood-brain barrier at approved doses — which is part of why it has such a strong human safety record.
Medical uses of ivermectin tablets
| Condition | Type | Standard Dose |
|---|---|---|
| Strongyloidiasis | Intestinal roundworm infection | 200 mcg/kg, single dose |
| Onchocerciasis (river blindness) | Filarial worm infection | 150 mcg/kg, once yearly |
| Scabies | Skin mite infestation | 200 mcg/kg, repeat in 2 weeks |
| Head lice (pediculosis) | Ectoparasite | 200–400 mcg/kg, single dose |
| Lymphatic filariasis | Filarial infection | 200 mcg/kg + diethylcarbamazine |
| Ascariasis | Roundworm (off-label support) | 200 mcg/kg |

Ivanorm vs Iverheal vs Iverjohn vs Ivercen: Head-to-Head
Strengths Comparison
| Strength | Ivanorm | Iverheal | Iverjohn | Ivercen |
|---|---|---|---|---|
| 3mg | Yes | Yes | Yes | No |
| 6mg | Yes | Yes | Yes | No |
| 12mg | Yes | Yes | Yes | Yes |
Verdict: Ivanorm, Iverheal, and Iverjohn offer the most dosing flexibility with all three strengths. Ivercen (or Covilife) is the better fit when you specifically need ivermectin 12mg tablets only.
Pricing Comparison (Approximate)
Prices vary by distributor, order quantity, and export destination. For current, itemized pricing — including how it compares to GoodRx coupon pricing for US-based buyers — see our dedicated ivermectin price comparison page.
Efficacy Comparison
All four brands contain the same active ingredient — Ivermectin IP/USP — at identical milligram strengths. Generic ivermectin formulations manufactured to pharmacopoeial standards show consistently similar efficacy, and bioavailability differences between brands are minimal. Therapeutic outcome is mostly determined by:
- Correct dosing based on body weight (200 mcg/kg for most indications)
- Manufacturing quality and Good Manufacturing Practice (GMP) compliance
- Storage conditions (cool, dry place)
- Patient compliance and follow-up dosing schedule
Key point: no clinical evidence suggests one brand of Ivermectin IP is therapeutically superior to another at an equivalent dose. The choice between brands comes down to availability, price, and supplier reliability.
Side Effects Comparison
Because all four brands share the same active ingredient, the side-effect profile is identical across Ivanorm, Iverheal, Iverjohn, and Ivercen — side effects are tied to ivermectin itself, not the brand.
Common side effects (all brands)
- Mild itching or skin rash
- Nausea or stomach discomfort
- Dizziness or headache
- Diarrhea (especially at higher doses)
Serious side effects (rare — seek medical attention)
- Mazzotti reaction: fever, headache, swelling, and eye irritation — occurs in roughly 10% of patients treated for onchocerciasis, from antigen release as parasites die
- Difficulty breathing, or swelling of the face, lips, or throat
- Severe skin rash with pus
- Problems with balance or coordination
- Postural hypotension (mainly with high parasite load)
Ivermectin doesn’t readily cross the blood-brain barrier in humans at approved doses, which is part of its strong safety record — but always use human-approved formulations only, never veterinary products.
Availability and Export Comparison
| Criteria | Ivanorm | Iverheal | Iverjohn | Ivercen |
|---|---|---|---|---|
| International export | Yes | Yes | Yes | Yes |
| Bulk order available | Yes | Yes | Yes | Yes |
| Multiple strengths | Yes (3) | Yes (3) | Yes (3) | No (1) |
| Price competitiveness | Medium | High | Medium | High |
| Global brand recognition | Medium | Very High | Medium | Medium |
If you’re trying to get ivermectin shipped to the USA, UK, or Australia, availability and shipping timelines are a bigger factor than the brand name itself — see our country guides for shipping to the USA, the UK, and Australia.

Frequently Asked Questions
Are Ivanorm, Iverheal, Iverjohn, and Ivercen the same medicine?
Yes. All four are generic formulations of Ivermectin IP/USP — the same active ingredient at the same milligram strengths. Clinical efficacy is essentially identical at the correct dose. The differences lie in brand name, manufacturer, packaging, and price.
Which brand is best for scabies treatment?
All four work equally well for scabies when dosed correctly at 200 mcg/kg. For a standard 60–70kg adult, the typical regimen is one 12mg tablet on Day 1 and one on Day 14. Brand choice depends on local availability and your doctor’s recommendation.
How do I order ivermectin tablets online?
Ivermectin tablets are available from licensed Indian pharmaceutical exporters. International buyers should confirm they’re ordering from a GMP-certified supplier and check the import regulations of their own country before placing an order, and should always verify the product is human-grade — not a veterinary formulation. You can browse current stock and strengths on our ivermectin tablets category page.
Is Iverheal stronger than Ivanorm?
No. At the same milligram strength (e.g., both at 12mg), they deliver the same amount of active ivermectin and the same therapeutic effect. Strength is determined by milligrams per tablet, not by brand name.
What’s the difference between Ivercen and Iverheal 12mg?
Both are 12mg ivermectin tablets. The difference is that Iverheal also comes in 3mg and 6mg strengths for dosing flexibility, while Ivercen is 12mg only. For patients who just need the standard 12mg dose, both are clinically equivalent.
Do I need a prescription to buy ivermectin?
Ivermectin is a prescription medicine in many countries. Requirements vary by destination, so check your local regulations and consult a licensed healthcare provider before ordering, regardless of which brand you choose.
How should ivermectin tablets be stored?
- Store at room temperature, in a cool, dry place
- Keep away from direct sunlight and moisture
- Keep out of reach of children
- Do not use after the expiry date printed on the blister pack
