Interceptor and Sentinel are the same thing (milbemycin oxime for heartworm) but Sentinel adds lufenuron (program) for fleas. So giving Interceptor and Sentinel at the same time would be double dosing on heartworm med.
Actually, Interceptor and I think Sentinel is five times stronger than it needs to be so the company can claim that it kills intestinal parasites.
