Hi, I have copd. My doctor prescribed etodolac 500mg tabs, 1 orally 2 times a day for inflammation and pain in my hip. I am only taking it once a day, at night. It seems to be making me sick about an hour after being taken, shortness of breath, coughing up mucus, tearing, watering eyes. Is this something to worry about? I stopped taking it because the watering eyes smacked of an allergic reaction to something. No watering eyes, shortness of breath or coughing at night since.
