Okay to take Fosamax with tamoxifen?


Question from Sue: I am currently taking tamoxifen. Is it OK for me to take weekly Fosamax concurrently? Fosamax causes me to feel ill. I get a "migraine headache." I now take my tamoxifen later in the day and it seems to help.
Answers - Charles Shapiro It's OK to take tamoxifen and Fosamax. However, if you're having side effects from the Fosamax and you really need to be on the Fosamax, then we would suggest discussing this with your doctor.
Marisa Weiss, M.D. I have patients who are on tamoxifen, calcium and Vitamin D. Over time if a DEXA scan shows that significant bone loss persists, then I may add another medication like Fosamax, Actonel, or Miacalcin. Sometimes a woman may need the combination of medications in order to get the best result. It is also true that you may not need the combination of medications indefinitely. If DEXA scans show substantial improvement, you may be able to maintain that bone strength without the full combination.

As you can see, all of these decisions take a lot of careful thought. Work closely with your physician to help guide you through these decisions. If you feel that your current doctor is unfamiliar with early onset of osteoporosis after treatment for breast cancer, try to find another physician with that area of expertise.

On Wednesday, August 21, 2002, our Ask-the-Expert Online Conference was called Keeping Your Bones StrongCharles L. Shapiro, M.D. and Marisa Weiss, M.D. answered your questions about how to measure the strength of your bones, how to find out your risk for osteoporosis, and what you can do to lower that risk.
