How do I determine if the RX code on my prescription pills match the type of drug they're supposed to be?

I have been 6 ways out of sorts for a week. I’m trying desperately to figure out what’s going on. Doc is no help. I need a new doctor.

A while ago it hit me that this really started when I got my blood pressure prescription refilled. They’re constantly changing pill colors, pill sizes and pill shapes. Last time one of the pills was white. This time it was egg shaped and blue. It was also in a prescription bottle I hadn’t seen before. I didn’t think anything of it, because they change all of the time.

This L145 is listed on prescripton bottle as LOSARTAN/HCT.
“This 127 is listed on the bottle as Amlodipine.

How can I double check them?
