I have a pill. Small, yellow. One side has PD and underneath has a 30. nothing on the other side. any ideas?
PD usually stands for Parke Davis, now owned by Pfizer.
A lot of their tablets are no longer marketed in the US, so it could be old. I have not been able to find anything with PD 30 on it.
They also make veterinary tablets - so it could be one of those.
You could try contacting them direct to see if they can help you.
