Have developed a heart rhythm disturbance, shortness of breath, edema of hands and legs/feet since being on Anastrozole. How worried should I be? Should I consider discontinuation discussions with my Dr.?
Yes Anastrozole ( Arimidex) could cause all the symptoms you have mentioned.
I have had quite a few bad side effects myself with this drug.When I discussed it with my doctor, she advised me to take Femara instead.
Although these two drugs are very similar regarding their side effects,I noticed that I can tolerate Femara much better.
By all means,talk to your doctor about your problems,(particularly concerning your heart). and see what he/she will advise you.
