Tapeworms are common parasites of the small intestine of dogs and cats.

Dosage and Administration

  • The dose can be added to a small meal or placed directly in the mouth, similar to tablet dosing.
  • Once a month, ideally on the same date.
  • If a dose is overdue by more than 15 days, treat immediately and resume monthly dosing.
  • If a dose is missed by 15-30 days, heartworm prevention can be maintained if treated immediately and monthly dosing resumes for at least the next 2 months.
  • If a dose is missed by more than 60 days, a veterinarian must be consulted in case the animal has contracted heartworm. Dosing may be recommenced, and a blood test for adult heartworm must be performed after 6 months.

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.
