Macrobid nitrofurantoin symptoms and conditions

After taking macrobid for about a week to treat my UTI, I developed chronic hives. It's been over 4 months now and I am still suffering badly. I was prescribed oral steroid for a week at first but it hasn't really helped. The hives keep coming back. I take claritin every day which helps a little bit but only temporarily. This is the last thing I need when I am trying to get pregnant. The stress of it all. If your doctor prescribes Macrobid (Nitrofurantoin-Maco), beware of the side affects!
