What Is Mebendazole And How Does It Work?
Mebendazole is a medicine doctors and pharmacists use to treat worm infections. If you or someone in your family is itching, uncomfortable, or has signs of worms, mebendazole is one of the first medicines that comes up. It is often sold under brand names like Vermox or Ovex.
How Does It Work?
Mebex 100 mg attacks worms in the gut. It blocks the worm’s ability to use sugar for energy, which makes the worms die out over a few days. After they die, your body gets rid of them through stool.
Who Usually Needs Mebendazole?
- Children and adults with pinworm (also called threadworm)
- People with roundworm, hookworm, or whipworm
- Sometimes, doctors use it for other rare worms
If you notice your child scratching at night, or if a doctor says someone in your home has worms, mebendazole is a common, trusted choice.
How Long Does Mebendazole Take To Kill Worms?
Here’s the answer everyone is searching for:
Mebendazole starts working straight after you take it, but it can take several days for all the worms to die and leave your body. You might see worms in your stool 2–3 days after starting the treatment.
- Pinworm: Most people notice fewer symptoms, like less itching, within two days.
- Roundworm, hookworm, whipworm: It can take up to a week for all the worms to be gone.
It’s normal if you still see worms for a few days. The medicine needs some time to work through your gut and reach every worm.
How Soon Will You Feel Better After Taking Mebendazole?
Most children and adults feel relief in two to three days. Itching and discomfort usually go away quickly. If symptoms last longer than a week, talk to your doctor.
Does Mebendazole Work The Same For All Worm Types?
No, not all worms are the same!
- Pinworm: One dose, and you’re done (but you’ll need a second dose two weeks later to catch any eggs that hatched).
- Roundworm and hookworm: You take it twice a day for three days.
Doctors may recommend different plans for rare types of worms, or if the infection is very strong.
Why Do Doctors Recommend A Second Dose?
Here’s something many people miss:
Mebendazole kills the adult worms, but not the eggs. Eggs can hatch later and cause a fresh infection. That’s why a second dose after two weeks is so important, especially for pinworms.
- Treat everyone in your house at the same time.
- Wash hands, trim nails, and clean bedding to stop eggs from spreading.
This makes it much less likely for the infection to come back.
How Should You Take Mebendazole?
- Pinworm: One 100mg tablet (chewable for children, easy to swallow)
- Roundworm, whipworm, hookworm: 100mg twice daily for 3 days
- Always check the instructions or ask your doctor or pharmacist
If you live in a busy city like New York, Chicago, San Antonio (or anywhere with a high population), worm infections spread easily. Local clinics and pharmacies can help with safe doses for kids and adults.
What If You Miss a Dose?
- Take the missed dose as soon as you remember.
- Don’t double up the dose—just finish the treatment as planned
Is Mebendazole Safe? What Are The Side Effects?

- Headache
If you see a rash, severe stomach pain, or anything that worries you, call your doctor right away.
