I found a couple of capsules, half is blue (or teal/green) and the other half is dark red with a lighter red on that end. It is imprinted Lilly F66. I have tried to look it up on the identification wizard and I can't find it anywhere. Can anyone tell me what this is? I would appreciate it. My boyfriend doesn't know if it's his medication that he misplaced and now found or what. I'd appreciate it if anyone can help us figure out what these are. Thanks.
