Mebendazole is a deworming medicine — an anthelmintic — that kills the common intestinal worms: roundworm, hookworm, whipworm and threadworm (pinworm). It works by starving the worm of the sugar it needs, so the worms die over a few days and pass out in the stool, sometimes visibly. It is barely absorbed from the gut, which is what makes it so safe: it acts where the worms are and very little reaches the rest of the body. It is on the WHO Model List of Essential Medicines and is sold without a prescription in Nigeria.

How to Verify Your Mebendazole is Genuine
- 1Check the strip or box for its NAFDAC registration number. In our copy of the register Mebox (A4-7734, GoldMoore), Fidson Mebendazole 100 (A11-100341) and MeCure's Mebendazole (A11-0714) are Active
- 2Emzor Mebendazole 100 mg (A11-100065) and Emzor Mebendazole 500 Chewable (A11-100066) are recorded as Inactive in our copy — common products, and a lapse is a renewal matter for the holder rather than proof of a fake, but confirm the current status on the official Greenbook
- 3Vermox and Wormin appear nowhere in our copy of the register. A pack carrying either name should be looked up by its printed number, and refused if it carries none
- 4Enter the number in our free NAFDAC checker and confirm the product name, strength and manufacturer match the pack. Deworming tablets are cheap, which keeps counterfeits rare, but expired stock in hot shops is common — check the expiry date too

What is Mebendazole?
Most Nigerians know it by an older name. Vermox, the Janssen original, and Wormin, an Indian import, were the names on chemist shelves for decades; neither appears in our current copy of the NAFDAC register, and the market today is Nigerian-made 100 mg tablets — Fidson Mebendazole 100 (A11-100341), MeCure's Mebendazole (A11-0714) and GoldMoore's Mebox (A4-7734), all recorded Active — plus Emzor's 100 mg tablet and 500 mg chewable, whose registrations our copy records as Inactive. A pack sold as Vermox or Wormin should be checked with particular care, because the name is doing work the register no longer backs.
Mebendazole and albendazole are close cousins and are often used interchangeably for routine deworming. Albendazole is better absorbed, so it is the one chosen when the worm has left the gut — hydatid cysts, neurocysticercosis, some tissue infections — and it is the standard single-dose tablet in Nigeria's school deworming programme. For the ordinary gut worms a household picks up, either works.
What is Mebendazole used for?
In Nigeria, Mebendazole is commonly used for:
- Threadworm (Enterobius) — the itchy bottom at night that passes round a family
- Roundworm (Ascaris), hookworm and whipworm (Trichuris), singly or together
- Routine periodic deworming in children from about one year of age, and in adults
- Hookworm-related anaemia, together with iron treatment
Dosage
IMPORTANT
Always follow your doctor's or pharmacist's instructions. The information below is for general reference only.
Adults
For threadworm: one 100 mg tablet as a single dose, repeated after two weeks because eggs survive the first dose — and the whole household treated the same day. For roundworm, hookworm and whipworm: 100 mg twice a day for three days, or a single 500 mg tablet. Routine deworming: 500 mg once, or 100 mg twice daily for three days, every three to six months in areas where worms are common. Tablets can be chewed, crushed or swallowed, with or without food; the 500 mg tablet is made to be chewed.
Children
From one year of age children take the same doses as adults — the worms are the same size whoever carries them. Children under one year are not routinely given mebendazole; between one and two years it is given in deworming programmes under health-worker direction. Crush the tablet into a little food for a child who cannot chew it safely.
Elderly
No dose change.
Threadworm reinfection is the rule, not the exception: treat everyone in the house on the same day, wash bedding and underwear in hot water, cut and scrub fingernails, and repeat the dose at two weeks. Worms may be seen in the stool for a few days after treatment; that is the medicine working. Deworming does not need to be done more often than every three months, and a child who is still pot-bellied or anaemic after treatment needs a clinic visit, not a second strip.
Side Effects
General information for a reader holding a pack, not a substitute for a doctor or pharmacist. If something on the serious list is happening, seek care now.
Common side effects
- •Stomach pain, wind, bloating or mild diarrhoea, especially when there are many worms to expel
- •Nausea; occasionally headache
Serious side effects — seek medical help immediately
- Allergic reaction — rash, hives, swelling of the face or lips, difficulty breathing
- Convulsions have been reported, mostly in infants, which is why it is not given routinely under one year
- At the high, prolonged doses used for tissue infections (not for ordinary deworming): low blood counts and liver upset
When to see a doctor
Ordinary deworming rarely needs a doctor. See one for severe or persistent abdominal pain, vomiting that will not stop, a rash or swelling after the dose, a convulsion, or if a child remains pale, pot-bellied or failing to grow after treatment — the cause may not be worms, or may be a worm mebendazole does not kill, such as bilharzia or tapeworm.
Warnings & Precautions
General information for a reader holding a pack, not a substitute for a doctor or pharmacist. If something on the serious list is happening, seek care now.
Do not take Mebendazole if you have:
- Known allergy to mebendazole or albendazole
- Routine use in children under one year
- First three months of pregnancy, unless a doctor judges the benefit outweighs the small risk
Drug interactions
- •Carbamazepine and phenytoin lower mebendazole levels — only relevant for the high-dose tissue regimens, not for deworming
- •Cimetidine raises its levels
- •Taking mebendazole and metronidazole together has been linked to rare severe skin reactions (Stevens-Johnson syndrome); avoid the combination unless a doctor has chosen it
- •No interaction with food; a fatty meal increases absorption, which matters only for tissue infections
Pregnancy & Breastfeeding
Avoid in the first trimester because of a theoretical risk shown in animal studies, although large studies of women who took it accidentally have not shown harm. After the first trimester the WHO supports treating hookworm in pregnancy in areas where it is common, because the anaemia it causes is the greater danger. Very little passes into breast milk and breastfeeding can continue.
