1.1Postmenopausal Osteoporosis

Risedronate sodium delayed-release tablets are indicated for the treatment of osteoporosis in postmenopausal women. In postmenopausal women, risedronate sodium has been shown to reduce the incidence of vertebral fractures and a composite endpoint of nonvertebral osteoporosis-related fractures [ see Clinical Studies (14.1) ].

1.2Important Limitations of Use

The optimal duration of use has not been determined. The safety and effectiveness of risedronate sodium delayed-release tablets for the treatment of osteoporosis are based on clinical data of one year duration. All patients on bisphosphonate therapy should have the need for continued therapy re-evaluated on a periodic basis. Patients at low-risk for fracture should be considered for drug discontinuation after 3 to 5 years of use.

Patients who discontinue therapy should have their risk for fracture re-evaluated periodically.
