Topic: New Information - Drug interaction between Tarceva and Omeprazole
I have been on an acid blocker ever since I started taking Tarceva in September 2009 (first generic Omeprazole, then Nexium). I learned last week (May 2010) that these medications highly affect the absorption of Tarceva. Apparently, this information came out in 2008, but the inserts that came with my medication are dated 2007 and do not mention this. Below is a link that mentions this specific interaction. Please let others know!
