Indications: Treatment of the following nematode infections: large roundworms (Ascaris suum), nodular worms (Oesophagostomum species), lungworms (Metastrongylus species), intestinal threadworms (Strongyloides ransomi), swine kidney worms (Stephanurus dentatus).

Limitations: It is recommended that regular feed be withheld overnight and worming feed administered the following morning. Dilute supplement with non-medicated feed as directed. Feed the equivalent of 1 pound of 0.08 percent worming feed per 100 pounds of body weight of pigs to be treated. May be fed as sole feed or thoroughly mixed with 1 to 2 parts of regular feed prior to feeding. When medicated feed is consumed, resume normal feeding. Pigs maintained under conditions of constant worm exposure may require re-treatment within 4 to 5 weeks after the first treatment due to reinfection. The label shall bear the caution, "Excessive salivation or muzzle foam may be observed. This reaction is occasionally seen and will disappear in a short time after medication. If pigs are infected with mature lungworms, coughing and vomiting may be observed soon after medicated feed is consumed. This reaction is due to the expulsion of worms from the lungs and will be over in several hours.''

A tolerance of 0.1 part per million is established for negligible residues of levamisole hydrochloride in the edible tissues of cattle, sheep, and swine.
