About Biheldon
Affordable worming, without the vet markup.
Biheldon was founded to give everyday pet owners — and the breeders, fosterers, and multi-pet households who care for more animals than most — access to a broad-spectrum wormer at a price that doesn't make regular treatment a luxury.
Our tablets are manufactured in the European Union to authorised-veterinary-medicine standards. Each scored tablet contains praziquantel 50 mg and pyrantel embonate 150 mg — the same active-ingredient combination as Drontal Cat, with a dosing-by-weight guide printed on every box. One box of 30 scored tablets covers months of routine worming for a typical household.
We dispatch from inside the EU and ship internationally with tracked delivery — so whether you're in the UK, mainland Europe, the US, Canada, Australia, or further afield, you can follow your order from the moment it leaves us until it lands at your door.
What we stand for
Honest, evidence-based, affordable.
01 / Made in the EU
Authorised veterinary medicine
Manufactured to European standards as an authorised veterinary medicine. Active ingredients verified against the NOAH Compendium datasheets.
02 / Honest about limits
A wormer, not a flea product
Biheldon covers tapeworms, roundworms, and hookworms in one dose. It does not cover lungworm, whipworm, fleas, ticks, or mites — and we say so up-front on every page.
03 / Who we serve
Multi-pet households worldwide
Pet owners, breeders, fosterers, and rescue volunteers in the UK, EU, US, Canada, Australia, and beyond. Get in touch for bulk pricing.
