All medications, prescribed or over-the-counter, should be cleared with your oncologist.

Hi,
Before starting tamoxifen treatment, make sure you tell your doctor about any medications you are taking (including prescription, over-the-counter, vitamins, herbal remedies, etc.). It is advised not to take aspirin, or products containing aspirin unless your Doctor/Oncologist specifically permits this.
Please talk to your doctor if you can continue taking low doses of aspirin.
Take care...
