Was i given a different medication? D-Amphetamine salt comb vs Dextroamp-Amphetam

I normally take the salt combo everyday twice a day at 12.5 mgs. When i went to pick up my meds today, it was 10x more expensive and didn’t have the same name as it usually did as well as the colors on the pills are different. I’m just wondering if there is a major difference between the salt combo i normally take and what u was given
