DECTOMAX Injectable

Injectable Solution

DECTOMAX® Injectable Solution is a ready-to-use, colorless to pale yellow, sterile solution containing 1% w/v doramectin (10 mg/mL). In cattle, DECTOMAX is formulated to deliver the recommended dosage (200 mcg/kg of body weight) when given by subcutaneous (SC) or intramuscular (IM) injection at the rate of 1 mL/110 lb of body weight.

DECTOMAX® Injectable Solution is indicated for the treatment and control of gastrointestinal roundworms, lungworms, eyeworms, grubs (see precautions), sucking lice and mange mites. Consult your veterinarian for assistance in the diagnosis, treatment, and control of parasitism.

  • Approved Uses:

    DECTOMAX Injectable Solution is approved for:

    • The treatment and control of internal and external parasites of cattle.
    • It is safe for use in beef cattle, including pregnant cows, newborn calves and bulls.
    • The control of the following harmful species of gastrointestinal roundworms, lungworms, eyeworms, grubs (see precautions), sucking lice and mange mites. Consult your veterinarian for assistance in the diagnosis, treatment, and control of parasitism.
    • DECTOMAX Injectable solution has been proven to effectively control infections and protect cattle from reinfection with Cooperia oncophora and Haemonchus placei for 14 days, Ostertagia ostertagi for 21 days and for Cooperia punctata, Oesophagostomum radiatum and Dictyocaulus viviparus for 28 days after treatment.

    Product Highlights:

    • DECTOMAX Injectable solution was the first cattle endectocide or anthelmintic labeled for extended activity—up to 21 days—against Ostertagia ostertagi, one of the most damaging internal parasites. Controlling infection over an extended period delays accumulation of adult worms, subsequently reducing the number of parasite eggs shed onto pasture.
    • DECTOMAX also protects against infection or reinfection with Dictyocaulaus viviparus, Oesophagostomum radiatum and Cooperia punctata for up to 28 days.
    • No other single injectable product controls a broader spectrum of internal and external parasites as DECTOMAX—including 36 stages of adult parasites, L4 larvae and inhibited larvae.
    • As an injectable solution, DECTOMAX offers precision dosing.
    • DECTOMAX is a tissue-friendly injectable solution that can be administered by subcutaneous (SC) or intramuscular (IM) injection in the neck region. The recommended route is via SQ injection to minimize the risk of injection-site blemishes and is in accord with Beef Quality Assurance guidelines. DECTOMAX is safe for use in beef cattle, including pregnant cows, newborn calves and bulls.
  • Packaging

    100-mL, 200-mL and 500-mL multi-dose, rubber-capped amber glass bottles contained in a clear polycarbonate shield. The polycarbonate shield holds the bottle during use, has a pre-drilled eye-hook for easy hanging, and can be recycled.

    Dosage and Administration

    Administer DECTOMAX injectable solution at the recommended dosage of 1 mL (10 mg doramectin) per 110 lb body weight by either subcutaneous or intramuscular injection. Beef Quality Assurance guidelines recommend subcutaneous administration as the preferred route. Injections should be given using 16- to 18-gauge needles, regardless of administration route. Needles 1/2 to 3/4 inches in length are suggested for SC injections, which should be given under the loose skin in front of or behind the shoulder. A 1 1/2-inch needle is suggested for IM injections. The only area for IM injections is the muscular region of the neck

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

    • Parasites are found in almost all forage situates, including pastures
    • Internal parasites cause numerous problems:
      • Suppressed appetite and reduced feed intake
      • Reduced nutritional intake through decreased ability to digest and absorb nutrients
      • Inhibited immune system
        • Cattle respond poorly to vaccines and disease challenges
    • Reduced nutrition intake impacts many aspects of animal performance including:
      • Gain
      • Feed efficiency
      • Immune response
      • Reproduction

    What are the benefits of deworming?

    • Animal health technology that most affects average daily gain and resulting ROI
    • Calves get off to a better start after weaning
    • Cattle perform better during grazing season
    • Deworming protects weight gain, immune system and carcass quality

    What should producers do to properly deworm their cattle?

    • Deworm in the spring, before turnout, to reduce the total parasite load on a pasture
      • Proper treatment helps eliminate internal parasites and reduces reinfestation
    • Timing of deworming is crucial
      • Deworming too soon leads to the effects wearing off before the emergence of spring parasites
      • Deworming too late leads to cattle recontaminating the pasture and newborn calves

    Why use DECTOMAX Injectable Solution?

    • DECTOMAX Injectable Solution
      • DECTOMAX Injectable Solution is used in areas where the primary parasites are internal
      • DECTOMAX Injectable Solution allows for more precise dosage and application
    • Consult with a veterinarian to determine the best time to deworm cattle in the spring

    • For subcutaneous or intramuscular injection in cattle only.
    • Residue warning: Do not slaughter for human consumption within 35 days of treatment. A withdrawal period has not been established for this product in pre-ruminating calves. Do not use in calves to be processed for veal.
    • Warning: Not for human use. Keep out of reach of children.
    • DECTOMAX is highly effective against all stages of cattle grubs. However, proper timing of treatment is important. For most effective results, cattle should be treated as soon as possible after the end of the heel fly (warble) season. Destruction of Hypoderma larvae (cattle grubs) when these grubs are in vital areas may cause undesirable host-parasite reactions, including the possibility of fatalities. Killing Hypoderma lineatum when it is in the tissue surrounding the gullet may cause bloat. Killing H. bovis when it is in the vertebral canal may cause staggering or paralysis. These reactions are not specific to treatment with DECTOMAX, but can occur with any systemic treatment for grubs. Cattle should be treated either before or after these stages of grub development. Consult your veterinarian concerning the proper time for treatment. Cattle treated with DECTOMAX after the end of heel fly season may be retreated during the winter for internal parasites, mange mites or lice without danger of grub-related reactions. A planned parasite-control program is recommended

Important Safety Information:
DECTOMAX Injectable has a 35-day pre-slaughter withdrawal period. Do not use in dairy cows 20 months of age or older. Do not use in calves to be processed for veal. DECTOMAX has been developed specifically for cattle and swine. Use in dogs may result in fatalities.
