April 28, 2023by Anzen_Exports0

Mebendazole is a medication used to treat parasitic infections caused by worms such as pinworms, whipworms, roundworms, and hookworms. It works by preventing the worms from absorbing the sugars they need for survival. This medication is available in tablet form and can be taken orally.


The dosage of Mebendazole depends on the type of infection being treated, the age and weight of the patient and several other factors. It is imperative to follow the prescribed dosage by your doctor or pharmacist.

For pinworm infections, the usual dosage for adults and children over 2 years of age is a single 100 mg tablet, which may be repeated after 2 to 4 weeks if necessary. The doctor must determine the dosage for children under 2 years of age.

For other types of worm infections, the usual dosage for adults and children over 2 years of age is a single 500 mg tablet taken once daily for 3 consecutive days. Again, the doctor determines the dosage for children under 2 years of age.

Taking Mebendazole with food or milk increases its absorption and effectiveness. Also, it is advised to avoid grapefruit or grapefruit juice during treatment as it can interfere with the absorption of Mebendazole.

Side Effects

Like all medications, Mebendazole can cause side effects. However, only some experience them. Common side effects include:

  • Abdominal pain
  • Diarrhoea
  • Dizziness
  • Headache
  • Nausea
  • Vomiting

Contact your physician immediately if you experience any of the following:

  • Allergic reactions such as hives, rash, or itching
  • Fever
  • Joint pain or swelling
  • Severe abdominal pain
  • Yellowing of the skin or eyes (Jaundice)

Please note that Mebendazole may interact with other medications, so inform your doctor or pharmacist of any other medications you are taking.


Mebendazole should not be taken by pregnant or breastfeeding women unless directed by a doctor. Before taking this medication, inform your doctor of allergies or medical conditions.

It is advised to avoid alcohol while taking the medication as it may increase the risk of liver damage. Also, avoid driving or operating heavy machinery if you experience dizziness or drowsiness as a side effect.

In conclusion, Mebendazole is a medication used to treat parasitic infections caused by worms. It may cause side effects such as abdominal pain and diarrhoea, which usually do not require medical attention.

However, if you experience severe side effects, you must seek immediate medical attention. Before taking the medication, discuss any allergies or medical conditions with your doctor.
