The only way to get Fosamax out of your system is to stop taking it and wait for your body to clear it out. In the meantime, take over-the-counter pain medications (Advil, Aleve, Tylenol, aspirin,etc.) or prescription analgesics for the joint and muscle pain.
When you are feeling better, start taking strontium citrate for bone health. It does not have nasty side effects and can be bought at your local health food store or on-line.
