Description
Mebechrist (Mebendazole) 100 mg
Mebechrist is a brand name product identified here as containing mebendazole 100 mg. Mebendazole is an anthelmintic medicine used against certain intestinal worm infections. Regulatory sources for mebendazole products describe it as a broad-spectrum benzimidazole antiparasitic agent.
Active Ingredient and Medicine Class
Active ingredient: mebendazole.
Medicine class: benzimidazole anthelmintic. This class is used to treat susceptible helminth (worm) infections, especially intestinal nematodes.
Established Medical Uses
Verified prescribing information and product information identify mebendazole for the treatment of common intestinal worm infections, including pinworm (Enterobius vermicularis), roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura), and certain hookworm infections. Some official sources also describe use in mixed gastrointestinal infestations caused by these susceptible parasites.
How It Works
Mebendazole acts locally in the intestine and disrupts the worm’s ability to take up and use glucose. This interferes with energy production, weakens the parasite, and leads to its death or expulsion.
Important Safety Information
Mebendazole is contraindicated in people with known hypersensitivity to the medicine. Official labels also note important caution in pregnancy, particularly in the first trimester, because fetal risk cannot be excluded. Rare but serious blood disorders such as neutropenia and agranulocytosis have been reported, mainly with prolonged exposure and higher-than-recommended doses.
Clinically significant interactions include metronidazole, which has been associated with serious skin reactions when used with mebendazole, and cimetidine, which may increase mebendazole concentrations by inhibiting its metabolism.
Possible Side Effects
Reported adverse effects include abdominal discomfort, diarrhea, nausea, vomiting, and headache. More serious reactions are uncommon but may include allergic reactions and, rarely, blood count abnormalities or severe skin reactions when interacting medicines are involved.
Scientific Evidence
PubMed-indexed reviews and trials support mebendazole’s established role in soil-transmitted helminth infections. A review of 29 studies found high cure rates for Ascaris lumbricoides and lower efficacy against Trichuris trichiura and hookworm, while later clinical studies confirmed that efficacy can vary by parasite species and regimen.
