I was put on Aromasin 25mgm QD after finishing chemo and Herceptin

This answer was rated:

I was put on Aromasin 25mgm QD after finishing chemo and Herceptin for one year for Hers 2 positive breast cancer. I started almost immediately with cough and that progressed into cough and wheezing. I was only on it for 3 to 4 weeks. I have been on two cycles of prednisone and the sxs clear up only to return with in a matter of days after finishing prednisone. Lung Ct scan not showing any abnormalities. I have a history of asthma. I have been off Aromasin for about 1 month. How long will it take for the lung issues to clear up. Is this a side effect of Aromasin?

Hi there,


I am Mysticdoc, experienced Internal Medicine Specialist.


I am here to help you with your concerns.

mysticdoc :

Yes aromasin can cause cough, difficulty in breathing in 6% patients as side effects.

mysticdoc :

However, these symptoms are temporary and subside gradually over time.

mysticdoc :

Usually, your system will clear out aromasin effect within 3-4 weeks.

mysticdoc :

Since, lung CT scan is normal, there is no need for concern.

mysticdoc :

But, your pulmonary function test shows some diminished lung function.

mysticdoc :

Since there is no noticeable fibrosis of the lungs, this is not chemo related.

mysticdoc :

Herceptin also can contribute to these respiratory symptoms like aromasin.

mysticdoc :

That is why your symptoms are taking longer than usual to subside.

mysticdoc :

You should see definite improvement within next 3 months or so.

mysticdoc :

The improvement will be gradual and may take longer sometimes.

mysticdoc :

are you able to read my replies?

Customer: Yes I have read your reply I really did not think it would take so long to see improvement. Because it is really impacting my life. But I will try to remIn optimistic since you think this will get better. I wish my oncologist could give me some feedback on this but he remains vague. Thanks
mysticdoc :

I understand your concern.
