Drug Interaction Report

Etelcalcetide can significantly decrease the calcium levels in your blood, and combining it with other medications that also have this effect may increase the risk of hypocalcemia, or low blood calcium. Symptoms of hypocalcemia include numbness or tingling around your mouth, muscle spasms, convulsions, mental changes (irritability, depression, psychosis), increased pressure on the brain, and irregular heartbeat. Let your doctor know if you experience these or other unusual symptoms. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
