Interceptor Spectrum Tasty Chews can be safely used in puppies from 2 weeks of age, breeding males and females, pregnant females, and in collies sensitive to ivermectin.
If an animal with adult heartworm infection (and therefore circulating microfilariae) is given Interceptor Spectrum Tasty Chews, a transient shock-like reaction can occur. To avoid this, dogs should be tested for adult heartworm and treated if necessary, before starting Interceptor Spectrum Tasty Chews.
Studies have confirmed safety at up to 10 times the recommended dose.
