In a study, a single dose of Teriparatide did not change how digoxin affects the heart. Researchers checked this with a heart tracing (ECG) measurement called the systolic time interval. It runs from the start of the Q-wave to the closing of the aortic valve, and it shows digoxin's calcium-related effect on the heart.
Little or no effect is expected. You usually do not need to change anything, but still tell your doctor or pharmacist about every medicine you take.
