Mebendazole belongs to the family of medicines called anthelmintics. Anthelmintics are medicines used in the treatment of worm infections.
Mebendazole is used to treat:
mebendazole may also be used for other worm infections as determined by your doctor.
Mebendazole works by keeping the worm from absorbing sugar (glucose). This gradually causes loss of energy and death of the worm.
Mebendazole is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For mebendazole, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to mebendazole or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
mebendazole has been tested in a limited number of children 2 years of age or older and, in effective doses, has not been shown to cause different side effects or problems in children than it does in adults.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of mebendazole in the elderly with use in other age groups.
|All Trimesters||C||Animal studies have shown an adverse effect and there are no adequate studies in pregnant women OR no animal studies have been conducted and there are no adequate studies in pregnant women.|
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The presence of other medical problems may affect the use of mebendazole. Make sure you tell your doctor if you have any other medical problems, especially:
Mebendazole usually comes with patient directions. Read them carefully before using mebendazole.
No special preparations or other steps (for example, special diets, fasting, other medicines, laxatives, or enemas) are necessary before, during, or immediately after taking mebendazole.
Mebendazole tablets may be chewed, swallowed whole, or crushed and mixed with food.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
If you miss a dose of mebendazole, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
It is important that your doctor check your progress at regular visits, especially in infections in which high doses are needed. This is to make sure that the infection is cleared up completely and to allow your doctor to check for any unwanted effects.
