We had a conversation about this a while back (probably a year or two ago now), and I hope some of the others who recall it weigh in also.

There is also reason to believe that milk thistle can slow the transit time of certain types of heartworm preventatives. So, it is important to wait for several days for the medication to clear the liver before offering milk thistle.

Sorry I don’t recall the details. I look for more information when I have a chance, but I’m in a rush right now!
