What Should I Do If My Daughter With A Bacterial Kidney Infection Took Old Nitrofurantoin And Another Unknown Pill?

My question: My daughter has a bacterial urinary/kidney infection the doctor diagnosed Thursday, October 18. My 46-year-old-daughter is under extreme mental stress and is living with her father and me. I just found out she was not taking the medicine prescribed (which was sulfamethoxazole TMP DS. one tablet twice a day. The other was phenazophridine 100 mg Tab. Sorry, I had no idea I had to pay for this. Forget it. I just discovered at 10:45 this evening of October 19 that she had not taken any of these, even though she said she was. Instead she took medicine another nurses practitioner had prescribed for a kidney infection she had back in May 2018. This medicine was nitrofurantoin mono-mcr 100 mg (1 capsule twice a day for seven days.) Obviously, she didn t take all of them since there are 8 left out of a prescription for 14). THE BAD THING: she has been taking this nitrofurantoin mono-mcr instead of what was prescribed for her current condition. Also mixed in with the nitrofurantoin mono-mar as a two-tone dark and light green capsule with the word LUPIN on one side. Now she tells me she was taking this also. She doesn t even know what the LUPIN is for. I now have all her medicine and am administering it to her.
