I have taken prevacid for 4-5 years for reflux. started taking singulair and zyrtec 4 years ago for asthma and allergies. just dx with esophageal spams so after all these years on prevacid and singulair I can't see how either helps the spasms since i just acquired them. have been prescribed bentyl recently with no good coming from it. what I have noticed is eliminating alot of different foods one by one. I have multiple food allergies but since having my gallbladder out I've noticed i have had to cut out even more foods from my diet as they really effect me. Good luck to all.
