I take furosemide along with my blood pressure medicine. Recently I had symptoms like an allergy, sneezing, runny nose, constipation, etc. I had to use Tylenol in order to sleep. That has stopped now. But, now I have urges to urinate but nothing comes out most of the time. I am still urinating but not at the level and relaxing afterwords that I experienced. Should I stop the Lasix so I am not forced to expel more liquid. Did the allergic week change something?
