Description

Levamisole is a fast acting drug which acts on nematode nerve ganglia paralysing the worm’s musculature within seconds of contact. Unable to maintain their position, the worms are then ejected by normal peristaltic movement, usually within 24 hours of levamisole administration. Although it is certain that levamisole primarily influences the neuromuscular system of nematodes, it is possible that in some helminthes the inhibition of the fumarate reductase system contributes to the anthelmintic efficacy of levamisole. Levamisole is indicated for the treatment of infections by the following gastrointestinal worm species: Ascaris lumbricoides: Roundworm Necator americanus: Hookworm Ancylostoma duodenal: Hookworm E nterobius vermicularis: Pinworm Trichuris trichuria: Whipworm Strongyloides stercoralis: Threadworm Trichostrongylus colubriformis

May increase toxicity of phenytoin. Increases bioavailability of ivermectin; decreases bioavailability of albendazole. Alcohol causes disulfiram-like reaction.

Side-effects are infrequent. They are usually mild and transient and include nausea, vomiting, abdominal pain, giddiness(dizziness) and headache. An encephalopathylike syndrome has been reported to have occurred in a few patients two or three weeks after treatment.

Although studies in animals have shown that Levamisole produces no teratogenic effects, current medical practice requires that the benefits of any drug used during pregnancy should be weighed against the possible dangers.

Effect on ability to drive or operate machinery: There is no evidence to suggest that Levamisole , used for anthelmintic purpose, will produce sedation. Mild and transient giddiness is an infrequent side-effect of treatment. No precautions are suggested concerning the ability to drive or operate machinery. In case of concurrent microfilaraemia transient fever may occur.

Counter possible anticholinesterase activity with e.g. atropine. Control blood pressure and respiration . Do not use sedatives.
