COMPOSITION: Each tablet contains 100 mg Mebendazole
PHARMACOLOGICAL CLASSIFICATION: A.12 Anthelmintics, Bilharzia medicines, filaricides, etc.
PHARMACOLOGICAL ACTION: Mebendazole is a broad-spectrum anthelmintic, and causes selective disappearance of cytoplasmic microtubules in the tegumental and intestinal cells of affected worms. Secretory substances accumulate in Golgi areas, secretion of acetylcholinesterase and uptake of glucose is impaired, and glycogen is depleted. These effects are not noted in host cells. Immobilization and death of the parasites occur slowly, and clearance from the gastrointestinal tract may not be complete until 3 days after treatment with mebendazole.
INDICATIONS: Mebendazole is indicated for the treatment of single and mixed helminth infestations caused by:
Trichuris trichiura (whipworm)
Ancylostoma duodenale (hookworm)
Necator americanus (hookworm)
Strongyloides stercoralis (threadworm)
Taenia spp (tapeworm)
These effects are not noted in host cells. Immobilization and death of the parasites occur slowly, and clearance from the gastrointestinal tract may not be complete until 3 days after treatment with mebendazole.
Mebendazole is indicated in the treatment of infestations by Moniliformis moniliformis.
CONTRA-INDICATIONS: Mebendazole is teratogenic in experimental animals and should not be given during pregnancy and lactation.
Sensitivity to imidazoles.

In higher dosages, Wormgo may cause vomiting, fever, transient neutropenia, alopecia, bone marrow suppression, raised hepatic enzymes and glomerulonephritis. Agranulocytosis has been reported.
Usage in children below 2 years is not well documented, and as there have been very exceptional reports of convulsions in this age group, mebendazole should only be given to very young children if their infections interfere significantly with nutritional status and physical development.
