Asitrax Syrup Uses

Asitrax Syrup contains Levamisole. Asitrax uses:

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 wormspecies:

  • Ascaris lumbricoides: Roundworm
  • Necator americanus: Hookworm
  • Ancylostoma duodenal: Hookworm
  • E nterobius vermicularis: Pinworm
  • Trichuris trichuria: Whipworm
  • Strongyloides stercoralis: Threadworm
  • Trichostrongylus colubriformis

Asitrax Syrup Doses

Asitrax Syrup contains Levamisole 40 mg/5 ml. Asitrax doses:

The following doses of Levamisole are given as a single administration, preferably after a light meal.

  • Age 1-4 year: 1 Tablets or 5 ml Syrup
  • Age 5-15 year: 2 Tablets or 10 ml Syrup
  • Age 16 year and over: 3 Tablets or 15 ml Syrup

In cases of severe hookworm infection it is suggested that a second standard dose be given one or seven days after the first, whichever timing is feasible.


Side Effects

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.


Levamisole is the active laevo-isomer of tetramisole. It works by paralysing susceptible intestinal worms which are then excreted from the intestines. Levamisole also enhances cellular immune responses in humans.

Asitrax Precaution

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.


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

Pregnancy Lactation use

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.


There is no absolute contra-indication to the use of Levamisole
