Taking Carbocal with food and drinks
If you take Carbocal with foods that contain oxalic acid (found in spinach and rhubarb) or phytic acid (found in whole wheat bread and whole grain cereals), interactions may occur, so it is recommended not to take Carbocal during the two hours following consumption of foods high in oxalic acid and phytic acid.

During pregnancy, the daily intake of calcium should not exceed 2500 mg (including food and supplements).
Carbocal can be used during pregnancy in case of calcium deficiency.
