Generic Mebendazole Information

Introduction

Mebendazole is an oral antiparasitic drug used primarily to eradicate intestinal worm infections. It belongs to the benzimidazole class and is listed under the World Health Organization’s “essential medicines” for its proven efficacy, safety, and low cost. In Hong Kong, mebendazole is commonly prescribed for community‑acquired helminthic infections and is also stocked in many private pharmacies as a generic alternative to brand‑name products.

The active compound is Mebendazole itself, and the medication is classified as an antiparasitic. Although its main indication is the treatment of soil‑transmitted nematodes, clinical experience has shown utility in a handful of other parasitic conditions.

What is Mebendazole?

Mebendazole is the generic version of the original brand Vermox® (produced by GlaxoSmithKline) and is also marketed under names such as Mebex, Mebazole, and Bendozol in various regions. All these products contain the same active molecule, Mebendazole, at equivalent strengths.

The drug was first synthesized in the 197s by Janssen Pharmaceutica and later commercialised worldwide. In Hong Kong it is supplied by several licensed importers and can be obtained from our online pharmacy, which offers the generic formulation at near‑manufacturer pricing.

How Mebendazole Works

Mebendazole interferes with the parasite’s cellular structure by binding to β‑tubulin, a protein essential for microtubule formation. Microtubules are required for glucose uptake, intracellular transport, and mitosis in helminths. By preventing tubulin polymerisation, mebendazole blocks glucose absorption, leading to energy depletion and immobilisation of the worm. The parasite is then expelled from the gastrointestinal tract through normal peristalsis.

Because human cells use a different tubulin isoform with lower affinity for mebendazole, systemic toxicity is minimal. After oral administration, the drug is poorly absorbed (≈5 % bioavailability); the majority of the dose remains in the intestinal lumen where the parasites reside, providing a high local concentration with limited systemic exposure.

Onset of action occurs within a few hours, and worm clearance is usually complete within 24–48 hours. The drug’s half‑life in plasma is about 2–4 hours, but the therapeutic effect persists as long as the drug remains in the gut.

Conditions Treated with Mebendazole

*Regimens are representative; exact dosing should follow the prescribing information or a qualified clinician’s advice.

Mebendazole’s broad spectrum against several nematodes makes it a first‑choice therapy in primary care and travel clinics across Hong Kong.

Who is Mebendazole For?

Mebendazole is appropriate for:

• Adults and children ≥2 years who have confirmed or strongly suspected intestinal helminth infections.
• Pregnant women in the first two trimesters (category B) when the benefit outweighs potential risk; it is avoided in the third trimester.
• Breast‑feeding mothers (limited data suggest low infant exposure; caution is advised).
• Immunocompetent individuals with uncomplicated infections.

Mebendazole is not recommended for:

• Persons with known hypersensitivity to benzimidazole derivatives.
• Patients with severe hepatic impairment (bioavailability may increase, raising toxicity risk).
• Women in the third trimester of pregnancy.
• Cases of disseminated strongyloidiasis requiring ivermectin as the drug of choice.

Risks, Side Effects, and Interactions

Common

• Abdominal pain or cramping
• Diarrhoea, sometimes with loose stools
• Nausea or mild vomiting
• Headache
• Transient skin rash or mild pruritus

These events are usually self‑limiting and resolve without intervention.

Rare

• Liver enzyme elevation (ALT/AST) – monitor in patients with pre‑existing liver disease.
• Dizziness or vertigo.
• Mild leukopenia or thrombocytopenia (typically reversible).

Serious

• Severe allergic reactions (anaphylaxis, angio‑edema) – immediate medical attention required.
• Hepatotoxicity – rare cases of clinically significant hepatitis reported; discontinue if jaundice or persistent liver enzyme rise occurs.
• Aplastic anemia – extremely uncommon but fatal if unrecognised; monitor complete blood count if prolonged therapy is used.

Clinically Relevant Drug–Drug Interactions

• Cimetidine can increase mebendazole plasma levels by inhibiting gastric acid secretion, potentially enhancing systemic exposure.
• Carbamazepine, Phenytoin, Rifampicin (enzyme inducers) may reduce mebendazole concentrations, possibly lowering efficacy.
• Antacids have minimal effect due to already low absorption, but they may further decrease bioavailability.
• Warfarin – no direct interaction reported, but routine INR monitoring is prudent when co‑administered with any new medication.

Patients should disclose all current medicines, including over‑the‑counter herbal products, to avoid unexpected interactions.

Practical Use: Dosing, Missed Dose, Overdose

Standard Adult Dosing (based on the specific worm):

• Enterobius vermicularis – Single 500 mg tablet, repeat after 2 weeks if reinfection is suspected.
• Other nematodes (Ascaris, Trichuris, Hookworm, Strongyloides) – 100 mg taken twice daily (approximately 12 hours apart) for 3 days.

Pediatric Dosing (≥2 years):

• 2 kg–11 kg: 100 mg single dose.
• 12 kg–23 kg: 200 mg single dose.
• For infections requiring a 3‑day regimen, the appropriate tablet strength is divided to achieve 100 mg twice daily.

Missed Dose

If a dose is forgotten, take it as soon as remembered unless the next scheduled dose is within 4 hours. In that case, skip the missed dose; do not double‑dose.

Overdose

Acute overdose of mebendazole is rarely life‑threatening due to its poor absorption. Symptoms may include nausea, vomiting, abdominal pain, and transient diarrhoea. Management is supportive: monitor vital signs, maintain hydration, and seek medical evaluation if severe gastrointestinal symptoms or allergic reactions develop.

Practical Precautions

• Food: Taking the tablet with a meal improves tolerability and modestly increases absorption; however, efficacy is not dependent on food.
• Alcohol: No direct interaction, but excessive alcohol may exacerbate gastrointestinal irritation.
• Renal or Hepatic Disease: Use with caution; dose adjustment is not routinely required but clinical monitoring is advisable.

FAQ

• What tablet strengths are available for mebendazole in Hong Kong?
  Mebendazole is commonly sold as 100 mg tablets. Some distributors also provide 500 mg tablets for single‑dose regimens against pinworm infections. The tablet is round, white, and film‑coated, with inert excipients such as lactose and magnesium stearate.

• Does mebendazole require refrigeration or special storage conditions?
  No. Store the tablets at room temperature (15 °C–30 °C), away from direct sunlight, moisture, and heat sources. A dry cabinet or pantry is sufficient; do not keep the medication in the bathroom.

• Can I travel internationally with mebendazole in my luggage?
  Yes, the drug is classified as a non‑controlled medication. When travelling, keep the original packaging or a copy of the product label, and ensure the quantity aligns with personal‑use limits set by customs authorities (typically up to a 30‑day supply).

• Are there differences between the Asian and European formulations of mebendazole?
  The active ingredient and dosage strength are identical worldwide. Minor variations may exist in inactive ingredients (e.g., different fillers or coating agents) but these do not affect therapeutic efficacy. Always review the excipient list if you have known sensitivities.

• Is mebendazole safe for people with lactose intolerance?
  Many formulations contain lactose as an excipient. For strict lactose‑intolerant individuals, request a lactose‑free version where available, or verify the ingredient list before purchase.

• What is the legal status of importing mebendazole for personal use into Hong Kong?
  Hong Kong permits personal import of a 30‑day supply of non‑controlled medicines for personal use, provided they are not on the restricted list. Importers must retain proof of purchase and the medication must be for personal consumption, not resale.

• Can mebendazole affect the results of routine urine or blood drug tests?
  No. Mebendazole is not screened for in standard workplace or clinical drug‑testing panels, as it is not a substance of abuse and has negligible systemic concentrations.

• How long does it take for a stool sample to become negative after completing therapy?
  For most nematodes, ova are cleared within 2–5 days post‑treatment. However, a follow‑up stool examination is usually performed 2 weeks after the final dose to confirm eradication, especially for heavy infections.

• Why is a second dose sometimes recommended for pinworm infection?
  Enterobius vermicularis eggs can be re‑ingested from contaminated bedding or clothing. A repeat dose after 2 weeks targets any newly hatched worms, reducing the risk of recurrence.

• Has mebendazole been studied for any non‑parasitic uses?
  Preliminary research has explored its anti‑tumour properties, particularly in colorectal and brain cancers, due to its tubulin‑binding activity. These investigations remain experimental and mebendazole is not approved for oncologic indications.
