I'm currently taking Keflex (and 4 other meds including steriods) for a sinus infection. I woke up with a bladder infection and I'm wondering if it is ok to take Macrobid at the same time. I checked them on the drug interactions checker and it didn't indicate there would be a problem, but I've never taken 2 antibiotics at once.
