Brand Name: Actonel with Calcium
What is calcium carbonate and risedronate?
Calcium carbonate is a mineral that is needed for many functions of the body, especially bone formation and maintenance.
Risedronate is in the group of medicines called bisphosphonates (bis FOS fo nayts). It alters the cycle of bone formation and breakdown in the body. Risedronate slows bone loss while increasing bone mass, which may prevent bone fractures.
Calcium carbonate and risedronate is a combination medicine used to treat or prevent postmenopausal and steroid-induced osteoporosis.
Calcium carbonate and risedronate may also be used for purposes not listed in this medication guide.

You should not use this medicine if you have low levels of calcium in your blood (hypocalcemia), or a problem with the movement of muscles in your esophagus.
Do not take a calcium carbonate and risedronate tablet if you cannot sit upright or stand for at least 30 minutes. Risedronate can cause serious problems in the stomach or esophagus (the tube that connects your mouth and stomach).
What should I discuss with my healthcare provider before taking calcium carbonate and risedronate?

In rare cases, this medicine may cause bone loss (osteonecrosis) in the jaw. Symptoms include jaw pain or numbness, red or swollen gums, loose teeth, or slow healing after dental work. The longer you use calcium carbonate and risedronate, the more likely you are to develop this condition.
Osteonecrosis of the jaw may be more likely if you have cancer or received chemotherapy, radiation, or steroids. Other risk factors include blood clotting disorders, anemia (low red blood cells), and a pre existing dental problem.
