Mebendazole 100 mg tablets (Mebentel, Kachhela Medex) are a single-ingredient benzimidazole. Ten tablets sit in a strip. In human medicine this milligram is the one most often discussed for threadworm (pinworm), sometimes as a single dose repeated after two weeks, plus household hygiene. That schedule still belongs with a doctor or pharmacist — this article is not a dose.
It is not fenbendazole. It is not mebendazole 500 mg. It is not the ivermectin 25 mg plus mebendazole 250 mg combination. Match the carton to the advice you were given.
Why 100 mg is not a “starter” 500 mg
Five 100 mg tablets are not automatically one 500 mg tablet. Brands, scoring and the leaflet differ. If 500 mg was written down, open that page. If 100 mg was written down, do not “make up” the course from the larger carton.
Hygiene still matters for pinworm
A tablet does not replace washing hands, changing underwear and treating close contacts when a clinician says the household should be treated together. A 100-, 200- or 5000-tablet pack is a supply size, not a signal to dose every neighbour.
Safety
Tell a clinician about pregnancy, breastfeeding, liver disease and other medicines. Abdominal pain can occur as worms die. Seek care for rash, jaundice, severe diarrhoea or allergic swelling. Keep strips away from children. Not for COVID-19 or other viral illness.
Packs and shipping
