Flea and Tick meds (advice)

My Little lady (4.5 months )has started to have seizures . I've noticed it seems to only happen at the beginning of the month shortly after taking her simparica trio and always in the morning from the way from her bed to go outside to potty, so there's has not been any activity to get her ramped up.This month the vet just recommended giving her just a heart worm med( interceptor plus) and holding the simparica to see if it maybe the cause . I am curious if anyone else has had this issue with simparica and what other Frenchie parents use for their pups .
