Mixing Directions:

Mixing and Feeding Directions: STRONGID® C 2X™ is to be administered on a continuous basis either as a top-dress or mixed in the horse's daily grain ration at the rate of 1.2 mg pyrantel tartrate per lb of body weight daily. To achieve this dose, administer 0.5 oz of STRONGID® C 2X™ per 250 lb of body weight. (A STRONGID® C 2X™ measuring cup is enclosed. Please note it is different in size and shape from the original Strongid® C measuring cup due to the higher concentration of STRONGID® C 2X™). STRONGID® C 2X™ should be administered for the entire period that the animal is at risk to internal parasites. Unprotected animals that have grazed may already have an established S. vulgaris larval infestation. Before administering STRONGID®C 2X™, these animals should be treated with a therapeutic dose of a larvicidal product.

Foals may be administered STRONGID® C 2X™ as soon as consistent intake of grain mix is occurring. This is generally between 2-3 months of age.

STRONGID® C 2X™ may be used in mares at any stage of pregnancy or lactation. Stallion fertility is not affected by the use of STRONGID® C 2X™.

Consult your veterinarian before using in severely debilitated animals and for assistance in the diagnosis, treatment, and control of parasitism. Do not mix in feeds containing bentonite.

Do not use in horses intended for food.
