I recovered from ER (estrogen receptor) positive breast cancer and was prescribed tamoxifen to prevent the cancer from coming back. I wanted to do everything possible to make sure that my treatment was successful because I knew that in about one-third of patients taking tamoxifen, the cancer comes back anyway. It was then that I heard about Tamoxitest, a DNA test that includes a computerized review of all the medicines I was taking that could help my doctor optimize my chances of success with tamoxifen.

I then asked my doctor to prescribe the test and received a cheek swab DNA collection kit in the mail. I followed the simple directions to collect and send in my sample. On reviewing the results, my physician noted that I tested partially negative for a gene called CYP2D6 (pronounced sip two D six) which is required for tamoxifen to work. 

My doctor then logged into my drug management account in the GeneMedRx software to view my Tamoxitest DNA test results. This allowed my doctor to analyze the DNA test results against all of my medicines, including any non-prescription drugs, herbal preparations or other factors that could affect the success of my tamoxifen treatment. GeneMedRx also helped my doctor find out that the combination of medicines I was taking might be causing bad side effects. In using this program, my doctor discovered that one of my antidepressants was interfering with what little CYP2D6 activity I had and by changing the antidepressant my chances of success with tamoxifen treatment substantially increased.
