Overview of Mebendazole
Mebendazole is a type of anthelmintic, a class of drugs that kills parasitic worms. It works by disrupting the worms’ ability to absorb glucose, essentially starving them until they die and are expelled naturally through bowel movements. This process is both effective and generally well tolerated.
The drug comes primarily in a 100mg tablet form and may be chewable or swallowable. It’s available under several brand names and is prescribed globally for the treatment and management of worm-related infections in both adults and children.
How Does Mebendazole Work in the Body?
After oral intake, Mebendazole acts locally in the intestines, where most parasites reside. It inhibits microtubule formation in the worms, interfering with their cellular structure and metabolism. This disruption prevents them from absorbing nutrients, particularly glucose, which is vital for their survival.
Once weakened and immobilized, the dead worms are removed from the body through regular bowel movements. This mechanism of action makes Mebendazole highly effective for intestinal parasites without requiring high systemic absorption.
What Infections Can Mebendazole Treat?
1. Pinworm (Enterobiasis)
Pinworm infection is one of the most common parasitic infections, especially in children. Symptoms include intense anal itching, disturbed sleep, and irritability. A single dose of Mebendazole 100mg is usually effective, with a follow-up dose recommended after two weeks to prevent reinfection.
2. Roundworm (Ascariasis)
Roundworms are large parasites that inhabit the small intestine. Mebendazole is effective in eliminating them over a three-day course, taken twice daily.
3. Whipworm (Trichuriasis)
Whipworms affect the large intestine and may lead to chronic diarrhea or rectal prolapse in severe cases. Mebendazole is effective in treating whipworm infections with a multi-day dosing regimen.
4. Hookworm (Ancylostomiasis)
Hookworms attach to the intestinal lining and feed on blood, potentially leading to anemia and fatigue. Mebendazole is widely used to remove hookworm infections through targeted deworming strategies.
5. Mixed Infections
In areas with poor sanitation, patients may suffer from mixed worm infestations. Mebendazole’s broad-spectrum activity makes it an ideal choice for clearing multiple types of worms with a single medication.
Who Should Take Mebendazole?
Mebendazole is generally recommended for:
Adults and children above 2 years suffering from worm infections.
Family members of infected individuals to prevent household-wide reinfection.
School or daycare communities during an outbreak of pinworm or other parasites.
Travelers or residents in high-risk regions with poor hygiene and sanitation.
Always consult a physician for proper diagnosis and prescription. Self-treatment is not advised, especially in young children or immunocompromised individuals.
Recommended Dosage and Administration
The dosage of Mebendazole varies depending on the type and severity of the worm infection.
Pinworms: A single 100mg tablet. Repeat after 2 weeks if reinfection risk is high.
Roundworms, Hookworms, Whipworms: 100mg taken twice daily for 3 consecutive days.
Mixed Infections: Follow physician recommendations based on stool test results.
Mebendazole can be taken with or without food, and the tablets can be chewed, swallowed whole, or crushed and mixed with food. This flexibility is especially helpful when administering it to children or those with difficulty swallowing pills.
