What does mebendazole tablet do to your body?

Mebendazole is a medication widely used to treat various parasitic infections in the human body. This anthelmintic drug is effective against a range of intestinal worms, including pinworms, roundworms, and hookworms. As an essential tool in the fight against parasitic infections, understanding how mebendazole works in the body is crucial for those prescribed this medication.

Mechanism of Action:

Mebendazole belongs to a class of medications known as benzimidazoles. Its primary mechanism of action involves disrupting the normal functioning of the parasites’ cells, leading to their eventual death. The drug interferes with the parasites’ ability to absorb glucose, an essential energy source, resulting in a depletion of energy and eventual demise.

Effects on Parasitic Cells:

Parasites, including worms, rely on glucose to carry out various metabolic processes necessary for survival. Mebendazole specifically targets the microtubules in the parasites’ cells. Microtubules are crucial components of the cytoskeleton, providing structural support and facilitating intracellular transport. By binding to tubulin, a protein essential for microtubule formation, mebendazole disrupts the assembly and stability of microtubules in the parasites’ cells. This disruption hampers their ability to maintain cell shape, divide, and transport essential materials, ultimately leading to their death. buy mebendazole online at dosepharmacy.

Selective Toxicity:

One of the advantages of mebendazole is its selective toxicity. While it affects the parasites’ cells, it has minimal impact on human cells. This selectivity is attributed to differences in the way mebendazole interacts with tubulin in parasitic cells compared to human cells. The drug’s specificity is a key factor in its efficacy and safety for use in treating parasitic infections.

Administration and Absorption:

Mebendazole is typically administered orally, and its absorption occurs in the gastrointestinal tract. The drug is absorbed systemically, reaching its peak concentration in the blood within a few hours after ingestion. The absorbed mebendazole is then distributed throughout the body, including the liver, where it undergoes metabolism, and the kidneys, from where it is eliminated.

Clinical Applications:

Mebendazole is commonly prescribed for the treatment of various parasitic infections, such as pinworms, roundworms, whipworms, and hookworms. The duration of treatment may vary depending on the type of infection and the severity of symptoms. In some cases, a single dose may be sufficient, while more prolonged courses may be required for certain infections.

Considerations and Side Effects:

While mebendazole is generally well-tolerated, some individuals may experience mild side effects such as nausea, abdominal pain, or diarrhea. These side effects are usually transient and resolve on their own. It’s important to inform healthcare providers about any pre-existing medical conditions or medications being taken to ensure the safe use of mebendazole.


  1. What is Mebendazole?

    • Mebendazole is an anthelmintic medication used to treat various parasitic infections caused by intestinal worms, including pinworms, roundworms, whipworms, and hookworms.
  2. How does Mebendazole work?

    • Mebendazole disrupts the parasites’ cellular structure by binding to tubulin, a protein crucial for microtubule formation. This interference hampers the parasites’ ability to absorb glucose, leading to their eventual death.
  3. Is Mebendazole safe for humans?

    • Yes, Mebendazole is generally safe for use in humans. It exhibits selective toxicity, meaning it primarily affects parasitic cells and has minimal impact on human cells.
  4. What types of parasitic infections does Mebendazole treat?

    • Mebendazole is effective against various intestinal worms, including pinworms (Enterobius vermicularis), roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura), and hookworms (Ancylostoma duodenale, Necator americanus).
  5. How is Mebendazole administered?

    • Mebendazole is typically administered orally. The dosage and duration of treatment depend on the type and severity of the parasitic infection. It may be taken with or without food.
  6. Can pregnant or breastfeeding women use Mebendazole?

    • Pregnant or breastfeeding women should consult with their healthcare provider before using Mebendazole. While it is generally considered safe, individual circumstances may warrant specific considerations.
  7. What are the common side effects of Mebendazole?

    • Common side effects may include nausea, abdominal pain, and diarrhea. These side effects are usually mild and temporary. If persistent or severe, it is important to seek medical advice.
  8. Is Mebendazole effective in a single dose?

    • The efficacy of Mebendazole often depends on the type of parasitic infection being treated. While a single dose is effective for some infections, others may require a more prolonged course of treatment. Follow your healthcare provider’s recommendations.
  9. Can Mebendazole be taken with other medications?

    • Inform your healthcare provider about all medications, including over-the-counter drugs and supplements, before starting Mebendazole. Some medications may interact with Mebendazole, affecting its effectiveness or increasing the risk of side effects.
  10. How long does it take for Mebendazole to work?

  • The time it takes for Mebendazole to show its full effect varies. Some individuals may experience relief from symptoms shortly after taking the medication, while others may require more time. Follow the prescribed treatment plan for the best results.


In summary, mebendazole plays a crucial role in the treatment of parasitic infections by disrupting the parasites’ cellular structures and functions. Its selective toxicity and minimal impact on human cells contribute to its efficacy and safety. Understanding how mebendazole works in the body provides valuable insight into its mechanism of action, helping both healthcare professionals and patients navigate the treatment of parasitic infections effectively. As with any medication, it is important to follow healthcare provider instructions and communicate any concerns or side effects during the course of treatment.
