What to expect
Most people tolerate Tamoxifen (Nolvadex) well. Here is what is worth knowing going in, so nothing catches you by surprise.
A prescription drug and worth treating as one. It raises clotting risk and interacts with anticoagulants, so it needs a doctor in the loop rather than a forum. Note that it blocks the receptor instead of lowering estradiol, so your serum E2 can climb while it is working — that reading is not the problem it looks like. Suited to defined courses, not open-ended use.
Preparing it
Tamoxifen (Nolvadex) does not need reconstituting — it comes ready to use.
Not applicable — oral tablet.
