bladder infection
"Taking Keflex for a possible uti, 500mg 4x's a day for 7 days. Within 15 minutes of taking pill I get severe indigestion & heartburn. I already suffer from gerd & this makes it ten times worse. I have also had mild itching & blurry vision. I have 27weeks pregnant so there's not a lot of antibiotics out there that are safe to take so I guess I'm going to going to try & stick it out & finish it even though the heartburn is so bad I want to stop."
