Fosamax, Raloxifine and Natural Progesterone

Can I take my bone building drugs such as Fosamax and Raloxifine with progesterone?

Yes, you can, however if you are using progesterone for bone building it will be severely compromised, if not rendered ineffective for this purpose.

We suggest you consider why you are taking the bone building drugs in the first place and decide for yourself whether it is bone delay that you are seeking or bone building.

Because these bone building drugs are not forming new bone, they are actually delaying the resorption of old bone. Blocking off the action of absorbing old, brittle bone, prevents progesterone moving in to build new bone in place of the old.

On X-ray, bone building drugs look fantastic as the bone appears dense, but in actual fact may be quite weak and brittle because the X-ray is depicting ‘old’ bone that should have been removed and replaced with new.

Slowing bone resorption doesn’t necessarily make your bones stronger.

As explained above, there are two different actions involved - taking away old bone, rebuilding new bone. Ask your doctor for full disclosure of side effects, benefits, and the test trials, then look at these seriously because at the end of the day, it is your health, your decision, and your body.

Raloxifine blocks estrogen receptors. It is a selective estrogen receptor drug which has estrogenic effects on bones, and is known to cause hot flushes and blood clots. We don’t know what other effects it has on progesterone or visa versa.
