Wormentel 500 Mg

What is Wormentel 500 mg?

Wormentel 500 mg is an effective antiparasitic medicine that treats a variety of intestinal worm infections in animals. Its active ingredient is Fenbendazole and is known for its capacity to treat parasite-related illnesses such as roundworms, tapeworms, hookworms, and whipworms. Fenbendazole is an anthelmintic medicine that acts by reducing the parasites’ capacity to absorb glucose, causing them to die.

Key Features

How Does Wormentel 500 mg Work?

Wormentel 500 mg blocks tubulin, a protein required for the formation of microtubules, which is disruptive to cellular activities in parasites. It blocks the uptake of glucose, starving parasites of nutrients and energy. Wormentel 500 mg causes cellular injury, ultimately leading to parasite death.

Uses 

Wormentel 500 mg is prescribed to treat parasitic infections of the following types:

• It is used to treat infections caused by hookworms, Ancylostoma duodenale and Necator americanus.
• It is used to treat infections caused by roundworms, Ascaris lumbricoides.
• It is used to treat infections caused by whipworms, Trichuris trichiura.
• It is used to treat infections caused by Pinworms, Enterobius vermicularis.

Dosage 

Route of administration: For oral administration only

Standard dosage:

Sheep & Goat: 5 mg/kg body weight as a single dose

Cattle & Horse: 7.5 mg/kg body weight as a single dose

Side Effects

In rare cases, more severe side effects such as allergic reactions, severe gastrointestinal issues, or liver problems may occur. If you experience any unusual symptoms, seek medical attention immediately.

Interaction

• Cimetidine, dexamethasone, and praziquantel enhance plasma levels of Fenbendazole sulfoxide (active metabolite)
• Antacids can reduce absorption
• Carbamazepine and phenytoin may reduce efficacy

Pharmacokinetics

• Fenbendazole is poorly absorbed, absorption increases with fatty meals.
• It undergoes rapid first-pass metabolism to active metabolite Fenbendazole sulfoxide.
• Peak plasma levels reach within 2-5 hours. Half-life is 8-12 hours.
• Excreted mainly in feces.

Precautions

• Contraindicated in pregnancy (Category C) and hypersensitivity
• Caution in animals with liver disease and lactation
• Monitor the liver enzymes profile in animals with prolonged use
• It should not be used for animal infants less than 3 months of age

Safety Profile

• Common adverse events: mild gastrointestinal upset (nausea, vomiting, diarrhea), headache, dizziness.
• Less common but important side effects: liver enzyme elevation, bone‑marrow suppression, allergic reactions.
• Long‑term or high‑dose safety unknown; monitoring recommended for liver function.

Efficacy Evidence

• Established antiparasitic activity: effective against roundworms, hookworms, whipworms, pinworms in observational use.
• No approved indication for cancer or other non‑parasitic conditions.
• Pre‑clinical studies (cell lines & animal models) report anti‑proliferative effects via microtubule disruption, glucose‑uptake inhibition, apoptosis induction.
