 Help/need to identify pills N 544 150
While cleaning earlier, I stumbled across a cigarrette wrapper with 3 pills in it. They were on the floor of my sons room piled under his dirty clothes. I have to find out what they are...tried the pharmacy/said they couldn't tell me because of the new privacy act laws...don't get me started on that one...anyway, this is what the pills look like.
They are round and white with N 544 on one side and 150 on the other side.
Please, someone let me know right away what these are...I'm very concerned!! |
