Medications
Several drugs and medications would reduce the levels of calcium in the body and hypocalcemia. For instance, lithium, which is often taken to deal with bipolar disorder, would affect the release of parathyroid hormone. Some other products such as corticosteroids, rifampin, phenobarbital, and phenytoin would also affect your metabolic rate and reduce the amount of absorbed calcium from foods. Therefore, it is important to read the label carefully and follow the instructions to prevent these side effects. [4]
