Quick Answer: What Is Vermact?
Vermact is a branded ivermectin tablet manufactured by Life Star (a Mankind Group company), available in 6 mg and 12 mg strengths. Its packaging labels the 6 mg tablet as an "Ivermectin Dispersible Tablet," with instructions to disperse it in a teaspoonful of water immediately before taking, rather than swallowing it whole — a formulation detail worth understanding if this is the product you've been prescribed. Ivermectin's medically recognised uses depend on country: in the UK, intestinal strongyloidiasis, lymphatic filariasis, and scabies; in Australia, onchocerciasis, strongyloidiasis, and scabies; in the USA, strongyloidiasis and onchocerciasis only.
What Is Vermact?
Vermact is the brand name Life Star uses for its ivermectin tablets. Ivermectin, the active ingredient, is an antiparasitic medicine that works by disrupting the nervous system of susceptible parasites. What sets Vermact apart from most other ivermectin brands stocked by Medionix is its tablet format: the packaging for the 6 mg strength specifically identifies it as a dispersible tablet, formulated to be mixed into a small amount of water rather than swallowed as a solid tablet.
What Does "Dispersible Tablet" Mean?
A dispersible tablet is designed to break down quickly when placed in liquid, forming a suspension that can be taken as a drink rather than swallowed whole. This format is commonly used where swallowing a solid tablet is difficult — for some children, for people with certain swallowing difficulties, or simply as a matter of preference or ease of administration. According to Vermact's packaging, the direction for use is to disperse one tablet in a teaspoonful of water immediately before administration. If your prescription is for Vermact specifically, this preparation step is part of correctly taking your dose — check the patient information that comes with your specific pack, since preparation instructions should always be confirmed against the leaflet for the exact product dispensed to you rather than assumed from a general description.
What Is Vermact Used For?
Ivermectin's approved uses differ by country:
| Country | Approved Uses |
|---|---|
| UK (MHRA/emc SmPC) | Intestinal strongyloidiasis; lymphatic filariasis; human sarcoptic scabies (typically second-line) |
| Australia (TGA) | Onchocerciasis; intestinal strongyloidiasis; scabies |
| USA (FDA) | Intestinal strongyloidiasis; onchocerciasis (not an approved scabies treatment) |
See our guides on strongyloidiasis, lymphatic filariasis, and UK scabies treatment for the detail behind each.
What Do These Conditions Actually Involve?
Strongyloidiasis is a roundworm infection that can persist quietly for years because of an internal reinfection cycle specific to this parasite. Lymphatic filariasis is a mosquito-borne infection of the lymphatic system that can lead to chronic swelling if left untreated over time. Scabies is a skin mite infestation causing intense itching, often worse overnight. Onchocerciasis (river blindness), relevant to Australian and US labelling, is transmitted by blackflies and can cause lasting skin and eye damage. Our guides on strongyloidiasis, lymphatic filariasis, and scabies cover each in full clinical depth.
How Does Vermact (Ivermectin) Work?
Ivermectin binds to glutamate-gated chloride channels in the nerve and muscle cells of parasites, causing paralysis and death. Human cells lack these channels, which is why the drug acts selectively on the parasite at approved doses — this mechanism is the same regardless of whether the tablet is swallowed whole or dispersed in water first.
How Is Vermact Dosed?
Dosing is weight-based — the standard single dose across ivermectin's licensed indications is approximately 200 micrograms per kilogram of body weight. Per the UK SmPC's reference table, a 6 mg tablet typically corresponds to a patient weighing around 25–35 kg, and a 12 mg tablet to around 51–65 kg. This is general reference information; your prescriber confirms your exact dose from your current weight. A dispersible format doesn't change the underlying weight-based dosing principle — it changes how the same calculated dose is physically taken.
How to Take Vermact Correctly
- If dispersible, prepare it as directed on your specific pack — typically dispersed in a small amount of water immediately before taking, not prepared in advance
- Take on an empty stomach, generally around two hours before or after food — food, particularly fatty food, has been shown to meaningfully increase how much ivermectin is absorbed, so the fasted-state instruction keeps your exposure aligned with your calculated dose
- Take the full prescribed dose at once, as directed
- Follow any repeat-dose schedule exactly — for scabies, a second dose roughly 7–14 days after the first is standard
Our how to take ivermectin guide covers timing, food, and missed-dose scenarios in more general depth.
When Should You Not Take Vermact?
The formal contraindication in current product information is hypersensitivity to ivermectin or any tablet ingredient. Extra caution applies if you weigh less than 15 kg, are pregnant or breastfeeding, have significant liver impairment, or have a travel or residence history in a Loa loa-endemic region.
Side Effects of Vermact
Commonly reported: nausea, dizziness, headache, and mild diarrhoea. A self-limiting reaction to dying parasites can occur in people treated for filarial infections. Rare but serious effects requiring urgent medical attention include severe skin reactions, signs of a severe allergic reaction, and confusion or seizures. See our full side effects guide.
Drug Interactions
No formal interaction studies exist for ivermectin; the clearest documented concern is with warfarin (raised INR reported). Our drug interactions guide covers this in detail.
What Happens If You Miss a Dose?
Missed-dose handling depends on your specific treatment course, since ivermectin regimens differ by condition. Contact your prescriber or pharmacist rather than guessing — see our dedicated guide for treatment-specific detail.
Vermact vs Other Ivermectin Brands
At a matching strength, Vermact contains the same active ingredient as Medionix's other ivermectin brands, including Iverheal, Iversun, Iverjohn, and Ivecop. The practical difference with Vermact is specifically its 6 mg dispersible tablet format — a genuinely different administration method, not a different or superior medicine.
If Your Doctor Has Prescribed Vermact
You can review the available strengths on the Medionix product pages for Vermact 6 mg and Vermact 12 mg tablets, alongside our wider ivermectin range.
Pregnancy and Breastfeeding
Current UK product information references data from around 300 pregnancies exposed to ivermectin without a clear pattern of harm being identified, but still recommends the medicine "should only be used when strictly indicated" in pregnancy. For breastfeeding, less than 2% of the administered dose is estimated to pass into breast milk — discuss your specific situation with your prescriber rather than relying on this figure alone.
Storage Information
Store Vermact tablets in a cool, dry place, protected from light and moisture, in the original packaging, out of reach of children. If your pack is the dispersible format, only disperse a tablet immediately before taking it — don't prepare it in advance and store the mixed solution.
