THIS IS HORRIBLE !!! Have severe UTI . (1st ever) . Picked up RX at 10:40 a.m. Took 1 pill at 11:00 a.m. Started off with sever nausea, belching, stomach cramps. Later had chest pains and shortness breath and now itching and it's 7:32 p.m. Trying not to go to ER. One pill. Can't wait till this stuff is out of my system. If it works for you, that is great. Not meant for everyone. It's Friday night, no relief i sight and the doctors office is closed for the weekend. Since 1st, and hopefully only uti, has anyone who used macrobid for uti , mind suggesting a better RX. Thank you :)
