Ivermectin 40mg Tablets — Generic Stromectol Antiparasitic | WHO Essential Medicine

 

What Is Ivermectin 40mg and What Is It Used For?

Ivermectin 40mg is a prescription antiparasitic tablet containing ivermectin — the same active molecule as brand-name Stromectol, manufactured by Merck. It is listed on the WHO Essential Medicines List and is backed by the Nobel Prize-winning research by Satoshi Ōmura and William Campbell (2015). Each 40mg tablet is a high-strength formulation used when the prescribed weight-based dose requires a large total amount of ivermectin, or to simplify tablet count for heavier patients.  Approved clinical indications include: Scabies (Sarcoptes scabiei infestation) | Strongyloidiasis (intestinal threadworm caused by Strongyloides stercoralis) | Onchocerciasis — river blindness (caused by Onchocerca volvulus) | Head lice (Pediculus humanus capitis) | Lymphatic filariasis (used as part of mass drug administration programmes).

 

How Does Ivermectin Work?

Ivermectin kills parasites by binding selectively to glutamate-gated chloride ion channels in the nerve and muscle cells of invertebrate parasites. This binding causes an increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. Crucially, these chloride channels do not exist in mammals in the same accessible form, which is why ivermectin is highly selective against parasites and has a well-established safety profile in humans at approved doses.  The drug is effective against both larval and adult forms of Strongyloides stercoralis. For scabies, it kills the Sarcoptes scabiei mite and is particularly useful in crusted (Norwegian) scabies, where topical treatments are less effective.

 

What Is the Correct Dose of Ivermectin 40mg?

Dosing is strictly weight-based at 200 mcg/kg as a single oral dose. The 40mg tablet is a high-strength formulation. Most adults do not require a full 40mg tablet for standard indications.  Scabies: 200 mcg/kg single dose, repeated after 7–14 days. Standard adult dose (70 kg): 15mg. A 40mg tablet would typically be prescribed for patients weighing 180–220 kg, or as part of a combination dose regimen directed by a physician.  Strongyloidiasis: 200 mcg/kg single dose (or two doses 2 weeks apart for hyperinfection).  Onchocerciasis: 150 mcg/kg single dose, repeated every 6–12 months.  Important: Always calculate the exact dose by body weight. A healthcare professional must determine the appropriate dose for individual patients. Do not self-dose without physician guidance.

 

Should Ivermectin Be Taken With or Without Food?

Ivermectin should be taken on an empty stomach — at least 1 hour before eating or 2 hours after a meal. Taking it with water only. Food, particularly a high-fat meal, significantly increases ivermectin bioavailability and can raise blood levels unpredictably, increasing the risk of side effects. This recommendation applies to all strengths including the 40mg tablet.

 

What Is the Difference Between Ivermectin 40mg and 12mg (or 6mg, 3mg)?

All strengths — 3mg, 6mg, 12mg, and 40mg — contain the same active ingredient (ivermectin) and work by exactly the same mechanism. The only difference is the amount per tablet. The 40mg tablet reduces the number of tablets required to reach the prescribed weight-based dose for larger patients or larger total doses. For example, a 70kg patient needing 15mg would take: 5 × 3mg tablets, or 2.5 × 6mg tablets, or 1.25 × 12mg tablets. The 40mg strength is typically used when clinical protocols call for larger total doses in heavier individuals.

 

What Are the Side Effects of Ivermectin?

Common side effects (related to parasite die-off — Mazzotti reaction): fever, itching, skin rash, swelling, dizziness, headache, muscle or joint pain, nausea, diarrhoea. These are usually mild and temporary, and are typically a sign that the drug is working against the parasites.  Serious side effects (rare): severe allergic reaction (anaphylaxis), low blood pressure, confusion, seizures, vision changes. Seek immediate medical care if these occur.  Neurological warning: Ivermectin must not be used in patients with Loa loa (loiasis) without specialist assessment, as high microfilarial density can trigger serious neurological events including encephalopathy.  Contraindications: avoid in children under 15 kg, pregnancy (unless benefit outweighs risk under medical supervision), breastfeeding, and known hypersensitivity to ivermectin.

 

Is Ivermectin Available Without a Prescription in USA, UK, and UAE?

A valid prescription from a licensed US physician is required. UK: Ivermectin is a prescription-only medicine (POM) in the United Kingdom.

Q&A Section —

 

Q: Can Ivermectin 40mg treat scabies?

Yes. Ivermectin is a first-line treatment for scabies, particularly for crusted (Norwegian) scabies or when topical permethrin has failed. The standard dose is 200 mcg/kg taken orally, repeated after 7–14 days. For most adults, a single dose of 12–15mg is sufficient; the 40mg tablet is appropriate for patients weighing approximately 180–220 kg or when clinically indicated by a physician.

 

Q: How long does Ivermectin take to work for scabies?

Ivermectin begins killing scabies mites within hours of ingestion. Most patients notice a significant reduction in itching within 48–72 hours. A second dose 7–14 days after the first is standard to kill any mites that hatched after the initial treatment. Itching may persist for 2–4 weeks after successful treatment as the skin heals — this does not mean the treatment has failed.

 

Q: Can Ivermectin 40mg be used for strongyloidiasis?

Yes. Ivermectin is the drug of choice for strongyloidiasis (infection with Strongyloides stercoralis). The WHO, CDC, and Cochrane reviews all support its use. Standard treatment: 200 mcg/kg daily for 2 consecutive days. For hyperinfection syndrome, treatment is extended and repeated. The 40mg strength may be used for high-dose regimens directed by an infectious disease specialist.

 

Q: Is Ivermectin safe for long-term use?

Ivermectin is not typically prescribed for long-term daily use. It is administered as single or short-course doses. In mass drug administration programmes for onchocerciasis and lymphatic filariasis, ivermectin is given once or twice annually and has been used safely in hundreds of millions of people over 40 years. Any extended or repeat use should only occur under medical supervision.

 

Q: What is generic Stromectol?

Stromectol is the brand name for ivermectin manufactured by Merck (MSD). Generic ivermectin tablets — including those manufactured by Winlife Pharma — contain the identical active ingredient at the same dose and work by the same mechanism. Generic formulations are bioequivalent to the branded product and are manufactured to pharmaceutical-grade standards. Winlife Pharma’s 40mg tablets are factory-sealed and clearly labelled with batch number and expiry date.
