Nitrofurantoin - Mylan 3422 And E122

I have a UTI and my doctor prescribed both mylan 3422 and E122, but I'm not sure how it's supposed to work because I have one of the E122 and nine of the mylan 3422 pills.

They both contain the same active ingredient, which is 100mgs of Nitrofurantoin. NDC codes: 51079-0348, the one with the Mylan marking is distributed by UDL Laboratories, and the one with the E122 is manufactured by Sandoz Pharmaceuticals, NDC code: 00185-0122, the original labeler of this one was Eon Labs.

When your doctor writes a prescription, and the medication is available as a generic, they actually don't get to dictate to the pharmacy which pills you will receive. It depends on what your pharmacy has in stock, except in cases where a generic isn't available, or if your doctor states that the brand is medically necessary on the prescription form.

Thus, it is likely that your pharmacy didn't have enough of one to fill your entire prescription, so they had to use pills from two different manufacturers, it is a very common practice.

The FDA lists its typical side effects as possibly including nausea, headache, dizziness, and diarrhea.

You can just take them as prescribed.

Is there anything else I can help with?
