What is Fenforce 150?
Fenforce 150 is fenbendazole 150 mg from GHB Lifesciences, positioned for canine and small-animal use. Fenbendazole is a broad-spectrum benzimidazole used in veterinary medicine since the 1970s. It is one of the most reliable single-agent dewormers in canine and feline practice and is a standard component of horse and livestock parasite-control programmes.
Werkingsmechanisme
Fenbendazole binds β-tubuline in parasite cells, preventing microtubule polymerisation. This blocks parasite glucose uptake and depletes glycogen stores — the worm starves over 2–3 days. The drug has very low oral bioavailability (~1–2% in dogs and humans), which is therapeutically advantageous: high concentrations in the gut lumen where intestinal worms live, near-zero systemic exposure.
Fenbendazole is metabolised in the liver to oxfendazole (the sulfoxide) and a sulfone metabolite, both of which retain anthelmintic activity. Excretion is primarily faecal.

Veelgestelde vragen
How do I dose Fenforce 150 for my dog?
50 mg per kg of body weight, once daily for 3 consecutive days. A 10 kg dog needs 500 mg per dose; a 25 kg dog needs 1250 mg per dose. Adjust tablet count to deliver the calculated mg. Repeat the 3-day course at 3 weeks if needed.
Can my puppy take Fenforce 150?
Yes from 6 weeks of age. The standard puppy schedule is fenbendazole at 2, 4, 6, 8 weeks then monthly to 6 months. Lower doses are used in pregnant bitches.
Will Fenforce 150 kill all worms my dog has?
Fenbendazole covers the major intestinal nematodes (roundworm, hookworm, whipworm) and Giardia. It does NOT reliably kill all tapeworm species — for tapeworm cover, add praziquantel or use a combined product.
What if my dog vomits the dose?
If vomiting occurs within 1 hour, repeat the full dose. Beyond 1 hour, the drug is partially absorbed; do not redose — just continue the schedule.
Can I give Fenforce 150 to my cat?
Yes, at the same 50 mg/kg single-daily dose for 3 days. Cats often dislike the taste of suspension; try mixing into a small amount of tuna or wet food.
Is fenbendazole safe in pregnant dogs?
Yes. It is one of the safer dewormers in pregnancy. Standard protocol is 25 mg/kg daily from day 40 of pregnancy through 14 days post-whelping — this prevents transmammary roundworm transfer to the puppies.
Can humans take Fenforce 150?
No. Fenforce 150 is a veterinary product not approved for human use. For human anthelmintic needs use albendazole, mebendazole, ivermectin, niclosamide, or praziquantel from this catalogue. The viral ‘fenbendazole for cancer’ story has no controlled human-trial evidence behind it.
Should I deworm a healthy-looking dog?
Yes. Most intestinal worms cause minimal visible symptoms in adult dogs but shed eggs into the environment, infecting other animals (and posing zoonotic risk to children). Routine 3-monthly deworming is standard veterinary advice in most countries.
Can I combine Fenforce 150 with flea and tick treatment?
Yes. Fenbendazole has no negative interaction with topical flea/tick treatments (frontline, advantage, isoxazolines). Many comprehensive parasite-control plans combine the two.
What about my puppy’s littermates?
Treat all puppies in the litter on the same days. The mother (bitch) should also be on the lactation deworming schedule. Bedding should be cleaned to reduce environmental egg load.
