Ivermectin (Heartgard, Iverhart), milbemycin (Interceptor, Sentinel), selamectin (Revolution), and moxidectin (Advantage Multi) are all heartworm preventatives. They just are different from each other.
I think you can use milbemycin for demodex, but if going with one of these drugs, ivermectin is very common.
Pups needs heartworm meds. So if ivermectin caused a problem, then another should be tried.
