Broad-Spectrum Dewormer


VALBAZEN® Suspension is the only drench dewormer that controls Cooperia spp., Ostertagia ostertagi and liver flukes. VALBAZEN Suspension is used to control internal parasites including tapeworms, liver flukes and more inhibited or larval forms of stomach worms than other oral drench dewormers.*

VALBAZEN Suspension offers the broadest parasite control in the oral drench dewormer category with 25 different parasites and larval stages covered.

  • VALBAZEN controls the fourth stage larvae of five key internal parasites and the inhibited larvae of Ostertagia ostertagi.

    While the dosage volume of VALBAZEN is larger than Safe-Guard® or Synanthic®, VALBAZEN has the most effective dosage covering 25% more parasites and larval stages than Safe-Guard and 47% more than Synanthic.

  • Cattle and Sheep: Valbazen is a broad-spectrum anthelmintic effective in the removal and control of liver flukes, tapeworms, stomach worms (including 4th stage inhibited larvae of Ostertagia ostertagi), intestinal worms, and lungworms.

    Valbazen is for the treatment of adult liver flukes in nonlactating goats.

    Cattle: Valbazen Suspension should be administered to cattle at the recommended rate of 4 mL/100 lb of body weight (equivalent to 4.54 mg of albendazole/lb, 10 mg/kg)

    - 500 mL of Valbazen 11.36% Suspension will treat 25 animals weighing 500 lb.
    - 1 liter of Valbazen 11.36% Suspension will treat 50 animals weighing 500 lb.
    - 5 liters of Valbazen 11.36% Suspension will treat 250 animals weighing 500 lb.

    Sheep: Valbazen Suspension should be administered to sheep at the recommended rate of 0.75 mL/25 lb of body weight (equivalent to 3.4 mg of albendazole/lb, 7.5 mg/kg).

    - 500 mL of Valbazen 11.36% Suspension will treat 332 animals weighing 50 lb.
    - 1 liter of Valbazen 11.36% Suspension will treat 664 animals weighing 50 lb.
    - 5 liters of Valbazen 11.36% Suspension will treat 3320 animals weighing 50 lb.

    Goats:  Valbazen Suspension should be administered to goats at the recommended rate of 4 mL/100 lb of body weight (equivalent to 4.54 mg of albendazole/lb, 10 mg/kg)

    - 500 mL of Valbazen 11.36% Suspension will treat 250 animals weighing 50 lb.
    - 1 liter of Valbazen 11.36% Suspension will treat 500 animals weighing 50 lb.
    - 5 liters of Valbazen 11.36% Suspension will treat 2500 animals weighing 50 lb.

  • What is the advantage of a larger volume dosage?

    • Benzimidazole products, like VALBAZEN, work through direct contact with the parasite. With a large rumen/abomasum, a larger volume dose is more likely to expose parasites to the active ingredient and can help improve product efficacy. It is also important to give the product more time to work by slowing the rate of passage by the rumen through reduced feeding or fasting prior to administration.1,2

    Is timing of administration a factor in controlling liver flukes?

    • Timing is critical for use of VALBAZEN to control liver flukes because the product is only effective against the adult form (minimal efficacy against the larval stages). Much of the damage to an individual animal’s liver occurs during the immature larval migrations. However, by controlling the only location in the life cycle that can produce eggs (adults), we can effectively reduce pasture contamination (if weather conditions are right) and positively impact subsequent cattle generations. The timing of when adults appear varies based on available moisture and environment. Work closely with your veterinarian to determine the best time to administer.

    Why should producers be concerned about protecting their cattle from parasites?

    • Parasites are found in all forage situations
    • Internal parasites cause numerous problems:
      • Suppress appetite and reduce feed intake
      • Reduced nutritional intake through decreased ability to digest and absorb nutrients
      • Inhibit immune system to cause cattle to respond poorly to vaccines and disease challenges
    • Reduced nutrition intake impacts many aspects of animal performance including:
      • Gain
      • Feed efficiency
      • Immune response
      • Reproduction

    Why invest in a brand name parasite control product?

    • VALBAZEN is produced by Zoetis, a company that adheres to high standards in its manufacturing facilities.
    • VALBAZEN has stood the test of time with producers and veterinarians by effectively controlling internal parasites including liver flukes, tapeworms and Cooperia sp.
  • Valbazen® Suspension controls the following internal parasites:
    Adult liver flukes (Fasciola hepatica)
    Heads and segments of tapeworms (Moniezia benedeni, M. expansa)

    Stomach and intestinal worms (Adult and fourth stage larval)
    Brown Stomach Worm, including 4th stage inhibited larvae (Ostertagia ostertagi),
    Barber Pole Worm (Haemonchus contortus, H. placei)
    Small Stomach Worm (Trichostrongylus axei)
    Thread-necked Intestinal Worm (Nematodirus spathiger, N. helvetianus)
    Small Intestinal Worm (Cooperia punctata, C. oncophora)

    Intestinal worms (Adult stage)
    Hookworm (Bunostomum phlebotomum)
    Bankrupt Worm (Trichostrongylus colubriformis)
    Nodular Worm (Oesophagostomum radiatum)

    Lungworms—adult and fourth stage larval (Dictyocaulus viviparous)

Cattle must not be slaughtered within 27 days or sheep and goats within 7 days after the last treatment with VALBAZEN. Do not use in female dairy cattle of breeding age or lactating goats. Do not administer to female cattle during the first 45 days of pregnancy or for 45 days after removal of bulls.
