The dose of mebendazole depends on the type of worm you are treating.
To treat pinworms, adults and children greater than 2 years old should take 1 tablet on the first day, then 1 tablet 2 weeks later and a third tablet 4 weeks after the first tablet. The first dose will get rid of the worms, but not the eggs that the worm may have left behind. The second dose will get rid of the second batch of worms that may have hatched from the eggs. The final dose ensures that all the worms are gone.
To treat other types of infestations, 100 mg (1 tablet) of mebendazole should be taken twice a day for 3 days. If symptoms remain after 3 weeks, your doctor may suggest a second treatment.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Mebendazole may be taken with food or on an empty stomach. Tablets may be crushed or chewed if necessary to make it easier to take the medication.
It is important to take this medication exactly as prescribed by your doctor.
