Well this was actually a DDS, but I got a script for Percocet in a retail store from this dentist. There was no strength so I tried calling him. DDS - Hello? Me - Hi Dr. XYZ I'm calling from ABC pharmacy. I got a script for this patient for Percocet and it doesn't have a strength on it... DDS - Oh? Hmm...what strength does it come in? Me - Well there are several different strengths sir. DDS - What's the most common? Me - 5... DDS - Sure that sounds good.
