I was prescribed generic Macrobida for UTI and developed pain in my legs and hips within a couple of days of starting it, then headache and feeling lousy, next severe constipation, then anxiety and sleeplessness (I was unable to sleep all night one night). The constipation, anxiety and sleeplessness were so severe and so unusual for me that I decided to look online to see if they might be related to the antibiotic since I hadn't changed anything else lately and found that other people have had the same problems and realized that the body aches, general malaise, and headache was probably related as well. My choices of antibiotic therapy are limited due to allergies and bacterial resistance issues so I will try to tough it out but wanted other people to be aware of some of the problems this medication has caused me.
