I was diagnosed with esophagitis and have always had issues taking some pills with certain coatings. I start to produce heavy saliva and sometimes the pills I can throw up to get it out of my system. I took a Rite Aid Allergy & Congestion Relief pill which is a generic of Allegra D and now I m experiencing the same thing. I can brief and the pill made it down to my stomach but I can t seem to stop producing foamy flem and throwing it up a little at a time. Is there anything you can recommend to stop the nausea and do you know how long this pill will take to digest completely if I can t throw it up. I don t seem to be able to bring it up. I think its too far down and past my esophagus.
