Patients who have hypercalcemia may be given medicine to reduce the level of calcium in the blood. Getting plenty of fluids helps the kidneys get rid of excess calcium in the blood. It also helps prevent problems that occur when calcium collects in the kidneys. If the kidneys aren't working well, dialysis or plasmapheresis may be necessary. In dialysis, the patient's blood passes through a machine that removes wastes, and the blood is then returned to the patient.
Plasmapheresis is used to remove excess antibodies produced by the myeloma cells.
This process thins the blood, making it easier for the kidneys and the heart to function. Multiple myeloma weakens the immune system. Patients must be very careful to protect themselves from infection. It is important that they stay out of crowds and away from people with colds or other infectious diseases. Patients who develop infections are treated with antibiotics or other drugs.
