DECTOMAX® Injectable 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 has a 35-day pre-slaughter withdrawal period. Do not use in female dairy cattle 20 months of age or older. Do not use in calves to be processed for veal. DECTOMAX Injectable has been developed specifically for cattle and swine. Use in dogs may result in fatalities. Consult your veterinarian for assistance in the diagnosis, treatment and control of parasitism.

  • Warning: Not for human use. Keep out of reach of children.

  • DECTOMAX® Injectable 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 Hbovis when it is in the vertebral canal may cause staggering or paralysis. These reactions are not specific to treatment with DECTOMAX Injectable 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 Injectable after the end of heel fly season may be re-treated during the winter for internal parasites, mange mites or lice without danger of grub-related reactions. A planned parasite-control program is recommended.
