Calcium chloride Pregnancy and Breastfeeding Warnings

Calcium chloride Pregnancy Warnings

Calcium is transported across the human placenta. The human fetus is entirely dependent on its mother for its supply of nutrients--including calcium--and oxygen and for the 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. The additional calcium required during pregnancy is mainly for the fetal skeleton. The recommended daily calcium supplementation to a pregnant woman averages 1,200 mg (compared with 400 mg/day for 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 generally require calcium supplementation.

Calcium chloride has been assigned to pregnancy category C by the FDA. Animal studies have not been reported. There are no controlled data in human pregnancy. It is not known whether calcium chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Calcium chloride should only be given during pregnancy when benefit outweighs risk.

Calcium chloride Breastfeeding Warnings

There are no data on the excretion of calcium chloride 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 with 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 generally require calcium supplementation.
