Several vets that I've spoken with have told me to use plain children's
Robitussin or Children's benadryl 1/4 tsp, which is about 1.25 cc no more
than 2x/day if needed (more preferably once a day).  Is it possible that
the Triaminic made her too sleepy which is why she appeared lethargic?
 
You might want to compare ingredients and see if there is a difference.
 
BTW, give Cheyenne a big hug and kiss for me - I understand she's turned
into quite the dog - she lived 2 doors from me and I was the one who got
her out of that bad situation.
