Dori,

Losul mentioned some time ago that milk thistle given too early after a heartworm preventative may interfere with the preventative (either by increasing or decreasing efficacy). Neither of which we would want to happen… I don’t think we ever decided when would be the optimal time to give the milk thistle — two days after, a week after etc? It would also depend, I’m sure, on what product is used and how it works.
