Taking Valbenazine Tosylate and Digoxin together can change how much Digoxin is in your blood. Digoxin is a heart medicine, and even a small change in its level can matter. Your doctor may order a blood test to check the Digoxin level while you take both. Do not change the dose of either medicine on your own.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
