Hello. I was reading on webMD (wont let me post link because im new member) about arimidex and it says This should not be used with the following medications because very serious interactions may occur: estrogens, tamoxifen. So if you took the arimidex up to the day you start your pct with nolva wouldnt the arimidex be in your system at the same time as the nolva? It doesnt say what the serious side affects are but its got me worried. Any thoughts? Thanks![]()
