7      DRUG INTERACTIONS
7.1 Digoxin
A single teriparatide dose did not alter the effect of digoxin on the systolic time interval (from electrocardiographic Q-wave onset to aortic valve closure, a measure of digoxin’s calcium-mediated cardiac effect). However, because teriparatide may transiently increase serum calcium, teriparatide should be used with caution in patients taking digoxin [see Warnings and Precaution (5.8) and Clinical Pharmacology (12.3)].
7.2 Hydrochlorothiazide
The coadministration of hydrochlorothiazide 25 mg with teriparatide did not affect the serum calcium response to teriparatide 40 mcg. The effect of coadministration of a higher dose of hydrochlorothiazide with teriparatide on serum calcium levels has not been studied [see Clinical Pharmacology (12.3)].
7.3 Furosemide
Coadministration of intravenous furosemide (20 to 100 mg) with teriparatide 40 mcg in healthy people and patients with mild, moderate, or severe renal impairment (CrCl 13 to 72 mL/min) resulted in small increases in the serum calcium (2%) and 24-hour urine calcium (37%) responses to teriparatide that did not appear to be clinically important [see Clinical Pharmacology (12.3)].
