The government wants women and their doctors to know that osteoporosis drugs, such as Fosamax and Actonel, may be causing women severe bone, joint and muscle pain.
The potential for pain is mentioned on the prescribing instructions, but the Food and Drug Administration thinks doctors might be overlooking the link.
The pain can occur anywhere from a few days to years after women start taking the medicines.
The FDA is conducting a review of the drugs, known as bisphosponates.
