Atypical femur fracture: There is evidence that long term use of this class of medication may contribute to a type of rare fracture of the long bone in the thigh (femur).
If you experience new or unusual pain in the groin, hip, or thigh area, contact your doctor as soon as possible.
Calcium and vitamin D: Calcium and vitamin D are important contributors to bone growth and strength. It may be necessary to take additional calcium or vitamin D supplements to get the best effect from etidronate if you are not getting enough from your diet. Your doctor may test you for low calcium levels or vitamin D deficiency before you start taking etidronate.
Dental procedures: A dental examination and any necessary dental procedures should be considered before you start treatment with etidronate-calcium if you have one of the following risk factors: cancer; chemotherapy, radiotherapy of the head or neck, treatment with corticosteroids, or dental problems or dental infections.

If you experience any pain in the jaw, especially after having a tooth removed, contact your doctor immediately.

Kidney function: If you have kidney disease or decreased kidney function, your doctor should closely monitor your condition while you are taking etidronate - calcium carbonate, as this medication can cause changes in kidney function.
