Macrobid and Macrodantin?

[Anonymous]

I just finished a cycle of macrobid prescribed to me by my OB referred urologist, and I know it is safe during pregnancy because I had also done a cycle my OB had prescribed. Immediately following the last macrobid, I was to start a cycle of macrodantin. I asked the urologist if it was safe during pregnancy, and he said he wasn't 100% versed in that to check with OB. I forgot to call OB and now it's Sunday night, am hesitant to call him since both medications are derivatives of the same drug, and I'm pretty positive are ok to take. Has anyone else taken Macrodantin for a UTI during pregnancy?
