Milbemycin oxime, praziquantel and lufenuron are the active ingredients in Sentinel Spectrum Tasty Chews.

  • Milbemycin oxime interferes with nerve transmission in invertebrates, which helps protect against heartworm, roundworm, hookworm and whipworm (minimum dose rate: 0.5mg/kg).
  • Praziquantel causes muscle spasm in tapeworm, which are then attacked by enzymes and disintegrate (minimum dose rate: 5mg/kg). It kills all intestinal forms of tapeworm except Spirometra spp, which require a higher than standard dose rate.
  • Lufenuron is an insect growth regulator that interrupts the flea breeding cycle. Adult fleas that feed on an animal treated with Sentinel Spectrum will produce eggs or larvae that do not develop to the adult stage. Therefore reducing the number of fleas in the environment.

Sentinel Spectrum Tasty Chews can be safely used in puppies from 6 weeks of age, breeding males and females, and collies sensitive to ivermectin. Sentinel Spectrum Tasty Chews have been safety tested at up to 10 times the recommended dose. If an animal with adult heartworm infection (and therefore circulating microfilariae) is given Sentinel Spectrum, a transient shock-like reaction can occur. To avoid this, dogs should be tested for adult heartworm and treated if necessary, before starting Sentinel Spectrum.
