Vermox (Mebendazole) 100 mg Chewable Tablets

Vermox is the brand name for mebendazole, an oral anthelmintic used to treat common intestinal worm infections such as pinworm, roundworm, whipworm, and hookworm. We offer it as a 100 mg chewable tablet, the only strength in our current offer, so every package we pack contains the same tablet in a different quantity.

What Vermox Is and What It Treats

Mebendazole belongs to the benzimidazole class of anthelmintics. Doctors prescribe it for gastrointestinal nematode infections, including Enterobius vermicularis (pinworm), Ascaris lumbricoides (roundworm), Trichuris trichiura (whipworm), and hookworm species. The standard regimens described here are intended for susceptible gastrointestinal worms; infections involving other tissues require a clinician's diagnosis and a treatment selected for the specific parasite and site of infection.

In the United States, the FDA-approved mebendazole 100 mg chewable tablet is marketed under the brand EMVERM; Vermox is an international brand of the same active ingredient, and customers should not assume that the brand names have identical labeling in every country.

How Mebendazole Works and How to Take It

Mebendazole interferes with the parasite's ability to build microtubules, the internal structural fibers that worms depend on for movement and for absorbing glucose. Without functioning microtubules, the worm can no longer take in the sugars it needs to survive and is eventually cleared from the intestine in the stool over the following days.

General Regimen

For pinworm, a single 100 mg dose is commonly used, with a repeat dose after two weeks often recommended because pinworm eggs can survive on surfaces and reinfect the same person. For roundworm, whipworm, hookworm, and mixed infections, a 100 mg dose taken twice daily, morning and evening, for three consecutive days is a typical general regimen. These are established treatment patterns rather than a specific dose we are assigning to any individual reader; an appropriate regimen always depends on the infection identified and a clinician's assessment.

The tablet can be chewed, swallowed whole, or crushed and mixed with food, and it may be taken with or without food. Taking it with a fatty meal increases how much mebendazole the body absorbs, which is not usually a concern for a short intestinal-worm course but is worth knowing if a longer course is prescribed for a different indication.

Available Strength and Package Sizes

We carry Vermox only as a 100 mg chewable tablet. What varies in our current offer is the quantity per package.

We currently offer this tablet in packages of 90, 120, 180, 270, and 360 pills. The number of tablets needed for a treatment course can be much smaller than these package quantities and depends on the diagnosed infection, whether repeat dosing is advised, and how many people a clinician recommends treating. Do not treat household members or repeat a course solely because tablets remain in the package.

Safety, Interactions, and Who Should Be Cautious

Mebendazole is contraindicated for someone with a known hypersensitivity to mebendazole or to another ingredient in the tablet; an unrelated or unspecified allergy history is not on its own a reason to avoid it. It has no recognized restriction related to diabetes and is not expected to cause drowsiness or affect the ability to drive or operate machinery.

Pregnancy, Breastfeeding, and Children

Because animal studies have shown embryo-fetal effects even though available human pregnancy data have not linked mebendazole to major birth defects or miscarriage, use during pregnancy calls for an individualized decision that weighs the infection against these findings, rather than an automatic yes or no. Small amounts of mebendazole pass into breast milk, and because effects on a nursing infant are not fully known, breastfeeding parents and their clinicians should weigh the treatment need against this caution. Pediatric use is established for children age 2 and older. Safety and effectiveness have not been established below age 2, and seizures have been reported in infants, including those younger than 1 year.

Drug Interactions and Monitoring

Carbamazepine and phenytoin can lower mebendazole levels in the blood by speeding up its breakdown, which may reduce its effectiveness against certain infections, while cimetidine can raise mebendazole levels by slowing that breakdown. Combining mebendazole with metronidazole has been associated with rare serious skin reactions, so this pairing is generally avoided. For short courses, routine laboratory monitoring is usually unnecessary, but a clinician may check liver function and blood cell counts when mebendazole is used at higher doses or for longer than a standard intestinal-worm treatment course.

Common and Serious Side Effects

At the doses used for intestinal worm infections, mebendazole is generally well tolerated. Commonly reported effects include abdominal pain, diarrhea, gas, nausea, vomiting, and headache. Rare but more serious effects that warrant prompt medical attention include unusual bruising or bleeding, signs of low blood cell counts such as persistent fever or infection, yellowing of the skin or eyes, and any severe skin or allergic reaction.

Storing Your Tablets

Store Vermox tablets at 68°F to 77°F; brief excursions between 59°F and 86°F are permitted. Keep the tablets in their original packaging, protected from direct light and moisture, and out of the reach and sight of children, as with any medicine kept at home.

Ordering Vermox From Us

Mebendazole chewable tablets are classified as prescription-only in the United States, which describes their legal status in this market rather than our own checkout requirements. Our ordering process does not require a prescription to accept your order, and where permitted we describe this option as available without a prescription. Customers who prefer to consult a clinician before starting treatment, or who have one of the cautions described above, are welcome to do so before placing an order with us.

We have offered medicines online since 2017, and our pharmacist-supported team is available 24/7 by email, live chat, and phone if you have questions about available package sizes, confirming the 100 mg strength, or tracking a shipment. Questions about the appropriate regimen, repeat dosing, or whether other household members should be treated should be discussed with a clinician.
