My 11#, almost 10 years old, Havenese/coton had wellness check and dental work done today. She had a lower front tooth

Customer: My 11#, almost 10 years old, Havenese/coton had wellness check and dental work done today. She had a lower front tooth break off several months ago and Dr. Sokol felt it was necessary to extract the remainder of the tooth to avoid future problems. She was prescribed Metronidazole 250 mg. .25 tablet every 12 hours and Gabapentin 100mg every***** Sokol said she didn’t make the dosage of the latter too high because she had a prednisone script about a week ago. Sokol said it may be too soon after prednisone. She went to vet at 9 am and came home about 6;30 pm. I gave her gabapentin about 5-6 hours ago. She is crying and whimpering—in other words, she is in pain. She can’t sleep, is restless. What can I do for her? I thought about giving her another gabapentin?!
