Health & WellnessMy dog used Nexgard, Simparica. Is Credelio safe after FDA warnings?
As you have already suggested, there are no absolutes. All the drugs the FDA mentioned in their recent warning are in the same class, including Credelio. Thus, I would venture to guess that it is unlikely Timmy with have a negative reaction to one but not the other. He does not appear to have a sensitivity to this class of drugs. There are always the off chance of allergies, but these are few and far between. Hope this makes sense.
