@mikee2all , sorry to hear about your coughing, but you can't blame Tagrisso. I've been on it for over 3 years and I've never had that problem. I cough and more when lying down, but that's because it's Spring and northern Alabama has seen over 5 inches of rain so far this month. EVERYTHING'S in bloom!

Beyond my personal experience, I recently had the opportunity to interact with over 200 survivors and caregivers, and that's not a Tagrisso side effect anyone mentions. I'm also applying to be a research advocate and am learning a lot about all types of lung cancer, including the EGFR mutations treated by Tagrisso. I should speak formally and say IF it's a side effect, it's very uncommon.

I'd look for other reasons. It is Spring in many places. I'm sorry I don't remember your history, but I encourage you to seek other reasons for your coughing. Have you tried antihistamines Have you contacted your Primary Care Physician? I've had a few other things pop up since I've been treated for cancer that have nothing to do with the treatments, although that was my first thought. It's a natural reaction. Ask yourself what you'd think is causing the coughing if you didn't have cancer treatments.

I hope you find some relief.
