I was on Remicade for 3 years and never had nausea. I was just diagnosed last week with H Pylori, which is a bacteria infection in the lining of my stomach. I was taking 2 Prevacid a day and then doc switched me to Nexum and still didn't help. You might have doc test for this since we all have low immune systems and are prone to infections.
Diagnosed in 91, Had 5 surgeries(2 hernias, gallbladder, colon resection, adhesions) Taking Humria, Pentasa, Prevacid, Sublingual B-12
