I have a history with esophagitis on top of stomach problems. I ve been placed on leviquin and today I m having inflammation and spasm attacks in the esophagus. I ve only been taking it for three days now. I have liquid donnatol which helps fairly fast with the spasms. Is leviquin in the class of Nsaids because I can take none. Does the med have a bad rap for inflammation?? I do see that it can cause nausea and vomiting, but I don t have that. Other factors that usually flare it up haven t been used unless Crystal Light lemonade can result in the same harm as it does with regular lemons.
