Dectomax™ Injection For Sheep

One handy jab treats worms and scab

Sheep ectoparasites cause welfare and production issues for sheep including loss of condition, disease transmission and in certain instances, death. Likewise, roundworms cause major impact on lamb growth rates and flock productivity.

Dectomax™ Injection for sheep is a 3-ML wormer that treats worms and scab with a single intramuscular injection.

  • It can be used as part of a sheep scab and worm control programme
  • It is effective against benzimidazole-resistant worms

Using Dectomax™ as part of the quarantine dose for incoming stock provides a second wormer alongside Zolvix™ and also gives scab control in the same treatment.

Additionally, a targeted treatment for ewes in poor condition or under nutritional stress at lambing time can help reduce the pasture contamination level for lambs later in the spring. Minimising the worm challenge faced by lambs will help them reach their growth potential.


In sheep: A single treatment of 1 ml (10 mg doramectin) per 33 kg bodyweight, equivalent to 300 mcg/kg bodyweight, administered by intramuscular injection for the treatment and control of Psoroptes ovis (sheep scab mite) and adult Nematodirus battus. In addition, adequate bio-security measures should be implemented to prevent re-infestation. Ensure that all sheep which have been in contact with infested sheep are treated. After treatment, contact between treated infected and untreated uninfected flocks must be avoided for at least 14 days. A single treatment of 1 ml (10 mg doramectin) per 50 kg bodyweight, equivalent to 200 µg/kg bodyweight, administered by intramuscular injection for the control of certain other gastro-intestinal nematodes and nasal bots.
