Directions For Preparing Soluble Pig Wormer Solution

When you are ready to deworm pigs, add water to the powder in this bottle up to the 500 mL mark. Agitate to mix thoroughly before using. If any solution is left over, it may be stored for up to 3 months in the tightly capped bottle; agitate well before using.

Directions For Use

Withholding water from pigs prior to treatment is not necessary for optimum anthelmintic efficacy and is not recommended during hot weather. Add 10 mL (2 teaspoonfuls) of the solution from the bottle to 1 gallon of water; mix thoroughly. Allow one gallon of medicated water for each 100 pounds of body weight of pigs to be treated. No other source of water should be offered. As soon as pigs have consumed all of the medicated water resume the use of regular water.

NOTE: Careful estimates of pig weights are essential for the proper performance of this product.

Pigs maintained under conditions of constant worm exposure may require retreatment within 4-5 weeks after the first treatment due to reinfection.

Levasole Soluble Pig Wormer Caution

Consult veterinarian before administering levamisole to sick swine.

Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism.

Salivation or muzzle foam may be observed. The reaction is occasionally seen and will disappear in a short time after the medication.

If pigs are infected with mature lungworms, coughing and vomiting may be observed soon after medicated water is consumed. The reaction is due to the expulsion of worms from the lungs and will be over in several hours. Follow the recommended dosage carefully to assure the removal of worms and avoid an overdose of levamisole.


Do not administer within 72 hours of slaughter for food.
