Has there been any correlation between taking Tarceva and increased in blood ammonia levels? I have a sister, age 61 who has vulvar cancer stage IV and she recently started taking Tarceva as of January 21st. She was sent to the ER for possible stroke but that has been ruled out. Only abnormal was her ammonia level.

Hi nancycarol,

Welcome to GRACE. I am sorry to hear of your sister’s diagnosis. I have not seen any scholarly discussion of Tarceva and elevated ammonia levels, here on GRACE or elsewhere.

I hope that your sister responds well to Tarceva for a long time.
