Calcium gluconate Pregnancy Warnings

Calcium is transported across the human placenta. The human fetus is entirely dependent on its mother for the supply of nutrients--including calcium--and oxygen and removal of waste products. Fetal accumulation of calcium occurs mainly during the third trimester. By the end of normal human pregnancy the fetus acquires approximately 28 grams of calcium and 16 grams of phosphorus for skeletal development.

The recommended daily calcium supplementation for a pregnant woman averages 1,200 mg (compared to 400 mg/day in the nonpregnant adult), with an additional 250 to 300 mg/day recommended during the last trimester. One quart of milk contains approximately 1,200 mg of calcium; women who do not consume milk or milk products may require calcium supplementation.

Calcium gluconate has been assigned to pregnancy category C by the FDA. It is considered a nutritional supplement. Neither animal reproductive studies nor controlled data from human pregnancy are available. Calcium gluconate should only be given during pregnancy when benefit outweighs risk.

Calcium gluconate Breastfeeding Warnings

There are no data on the excretion of calcium gluconate into human milk. Calcium is considered a normal nutritional component of human milk.

The calcium content of human milk averages 30 mg/dl. The recommended daily allowance (RDA) for calcium in the lactating woman is 1,200 mg (compared to 400 mg/day in the nonlactating adult). One quart of milk contains approximately 1,200 mg of calcium; women who do not consume milk or milk products require calcium supplementation.
