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.
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.
