• Active Ingredient Name: Mebendazole

Popular and Other Names:

• Brand Names: Vermox, Ovex

Mode of Action:

Mebendazole works by blocking glucose uptake in intestinal worms, which prevents them from absorbing nutrients. Without glucose, the worms lose energy, eventually leading to their death and elimination from the body through natural bowel movements. This mechanism helps to clear the worm infestation effectively without causing significant harm to the host.

• Follow-Up Dose: In cases of reinfection or persistent symptoms, a second dose may be recommended after 2-3 weeks.
• Children: Dosage for children should be confirmed by a healthcare provider based on age and infection severity.
