US health officials warn that certain osteoporosis drugs may cause severe pain.

The prescription drugs are in a class called bio-phosphonates. It includes Fosamax made by Merck and Actonel from Procter and Gamble.

The Food and Drug Administration says patients may have severe joint, bone and muscle pain within days or even years after treatment begins.

The FDA says they are reviewing the problem, but in the meantime, doctors should discontinue the therapy if patients report severe pain.
