I have many issues, diabetes, chf, high bp,interstitial lung disease. I have been in and out of the hospital 3 times since September. When I was dismissed the last time, I was given,Issorb, 2tabs, 4x daily. My head is always exploding! What can I take OTC and/or prescription for this. I have a doctors appt. next week. Is there something else that she can prescribe beside this?
