Understanding Vermox: A Comprehensive Guide for Patients

In the realm of healthcare, awareness and understanding of medications are crucial for informed decisions. One such medication, Vermox, has proven effective in treating various parasitic infections. This article aims to provide patients and the general public with reliable and accessible information on Vermox, breaking down its description, properties, indications, precautions, and more.

What is Vermox?

Vermox is a synthetic broad-anthelmintic, available in oral tablet and drinkable suspension forms. Each tablet contains 100 mg mebendazole, a key component in its pharmacological action. The suspension, on the other hand, contains 20 mg mebendazole per ml.

Key Ingredients:

  • Tablet: Microcrystalline cellulose, sodium starch glycolate, talc, maize starch, and more.
  • Suspension: Sucrose, microcrystalline cellulose, sodium carmellose, and various flavorings.

Understanding Vermox’s Action


Vermox works by interfering with the cellular tubulin formation in worms. This disruption hinders glucose uptake and normal digestive functions, leading to an autolytic process within the worm.


Mebendazole, the active ingredient in Vermox, is poorly absorbed after oral administration. This limitation arises from high first-pass metabolism and the drug’s low solubility. Approximately 80% of the absorbed fraction binds to plasma proteins.

Medical Indications

Vermox is prescribed for the treatment of various worm infestations, including:

  1. Enterobius vermicularis (threadworm/pinworm)
  2. Trichuris trichiura (whipworm)
  3. Ascaris lumbricoides (large roundworm)
  4. Ancylostoma duodenale, Necator americanus (hookworm)
  5. Strongyloides stercoralis
  6. Taenia spp. (tapeworm)

Safety Measures and Contraindications


Vermox is contraindicated in individuals with a hypersensitivity to the drug.

Warnings and Precautions

  1. Infants Below 1 Year: Vermox should be administered cautiously to infants below one year, considering the limited documented experience in this age group.
  2. Pregnancy and Lactation: While Vermox has shown embryotoxic and teratogenic activity in animal studies, its use in pregnant women should be carefully weighed against potential therapeutic benefits.

Dosage and Administration

Dosages vary based on the type of infection:

  1. Enterobiasis: Single dose of 1 tablet or 5 ml suspension.
  2. Ascariasis, Trichuriasis, Hookworm, and Mixed Infections: 1 tablet or 5 ml suspension bid for 3 consecutive days.
  3. Taeniasis and Strongyloidiasis: 2 tablets or 2 x 5 ml bid for 3 consecutive days (adults), 1 tablet or 1 x 5 ml bid for children.


Due to the frequent occurrence of reinfections by Enterobius vermicularis, treatment may be repeated after 2 and 4 weeks.

Adverse Reactions and Overdosage

Adverse Reactions

Adverse reactions to Vermox are generally minor, including transient abdominal pain and diarrhea. Hypersensitivity reactions such as rash and urticaria are rare.


In case of accidental overdosage, symptoms may include abdominal cramps, nausea, vomiting, and diarrhea. While there is no specific antidote, supportive measures like gastric lavage and activated charcoal may be considered.

How Vermox is Supplied and Stored

  • Vermox tablets come in blister packs, while the drinkable suspension is supplied in 30 ml bottles.
  • Storage conditions: Between 15 and 30°C.

Important Advice for Patients

  • Always follow your doctor’s prescription and usage directions.
  • Consult your pharmacist for guidance on contra-indications and proper use.
  • Do not alter the dosage or prematurely stop the treatment without consulting your doctor.
  • Keep all medicines out of reach of children.
