Hello! i went to urgent care yesterday due to peeing a lot - 6 to 7 times a hour every so often during a course of a day. they did a urine test and it showed infection. i started macrobid 100 mg yesterday . when should my symptoms improve?

Days. The antibiotic can kill the germs and stop their irritating action on your urinary tract but your bodies self healing action must repair the irritated areas for symptoms to subside. It usually takes a few days with gradual improvement.

Don't forget to add Cranberry juice to your daily consumption. You should start to experience relief within a few hours, seriously. If the antibiotics are working you get relief quite quickly. But keep going with it and drink lots of fluids to flush the kindneys and bladder and urethra out.
