Tarceva and Oxygen saturation decreased - a phase IV clinical study of FDA data

Summary:

Oxygen saturation decreased is reported as a side effect among people who take Tarceva (erlotinib hydrochloride), especially for people who are male, 60+ old, have been taking the drug for < 1 month also take Avastin, and have Lung neoplasm malignant.
