Hi there...I bet that was scary! I have heard of these two medications causing seizures if they are weaned too quickly. Our dog was on Tramadol (yes, they give this stuff to our pets) and we were told by the vet to taper him off over the course of weeks to prevent seizures. Just take the weaning nice and slow and take small cuts. Doctors tend to give us very fast tapering schedules that can cause problems.
