What is Vermox?
Mebendazole or MBZ is a medicine used to treat infections by worms. This includes pinworms, roundworms, tapeworms, hookworms, and whipworms. It is taken by mouth and acts to paralyze and kill worms infecting the digestive tract. This reduces the parasite burden to a low level, and since these worms are unable to complete their reproductive cycle within a single human host, the parasite burden remains low unless the person is reinfected. Mebendazole's low toxicity arises in part because very little of this drug is absorbed into the bloodstream. It is in the benzimidazole drug class.
It was introduced by Janssen Pharmaceutica in the early 1970s as an analog of an earlier drug, thiabendazole, relative to which it has the advantage of significantly reduced toxicity. It is included in the WHO Model List of Essential Medicines, a list of the most important medication needed in a basic health system.
