Interactions between your drugs
hydroCHLOROthiazide palopegteriparatide
Applies to: Exforge HCT (amlodipine / hydrochlorothiazide / valsartan) and palopegteriparatide
MONITOR: Treatment with thiazide diuretics, loop diuretics, and lithium may increase serum calcium levels, which may alter the therapeutic effects of palopegteriparatide. There are no clinical data available evaluating the safety of concomitant use of palopegteriparatide with these medicines, therefore, the clinical significance of the interaction is unclear. However, concomitant administration of teriparatide, of which palopegteriparatide is a pro-drug, with intravenous furosemide 20 mg to 100 mg, did not significantly affect calcium response in normal subjects or patients with mild to severe renal insufficiency. The increases in serum calcium and urinary excretion of calcium of 2% and 37%, respectively, was determined to be clinically insignificant. Similarly, the concomitant administration of hydrochlorothiazide 25 mg and teriparatide did not significantly affect serum calcium response. The reduction in urinary excretion of calcium of 15% was also determined to be clinically insignificant. However, the effect of higher doses of hydrochlorothiazide is unknown. On the other hand, long term use of lithium has been associated with hypercalcemia and hyperparathyroidism.
MANAGEMENT: More frequent monitoring of serum calcium is recommended when palopegteriparatide is administered concomitantly with thiazide diuretics, loop diuretics, or lithium, particularly upon their initiation, cessation, or after dosage adjustment. Patients should be advised to contact their doctor promptly if they develop symptoms of hypercalcemia such as nausea, vomiting, constipation, lethargy, muscle weakness or symptoms of hypocalcemia such as muscle spasms, carpopedal spasm, laryngeal spasm, tetany, convulsions, mental changes (irritability, depression, psychosis), increased intracranial pressure, papilledema, QT interval prolongation, and cardiac arrhythmias.

hydroCHLOROthiazide amLODIPine
Applies to: Exforge HCT (amlodipine / hydrochlorothiazide / valsartan) and Exforge HCT (amlodipine / hydrochlorothiazide / valsartan)
The antihypertensive effect of amlodipine and thiazide diuretics may be additive. Management consists of monitoring blood pressure during coadministration, especially during the first 1 to 3 weeks of therapy.

Drug and food interactions
valsartan food
Applies to: Exforge HCT (amlodipine / hydrochlorothiazide / valsartan)
GENERALLY AVOID: Moderate-to-high dietary intake of potassium, especially salt substitutes, may increase the risk of hyperkalemia in some patients who are using angiotensin II receptor blockers (ARBs). ARBs can promote hyperkalemia through inhibition of angiotensin II-induced aldosterone secretion. Patients with diabetes, heart failure, dehydration, or renal insufficiency have a greater risk of developing hyperkalemia.
MANAGEMENT: Patients should receive dietary counseling and be advised to not use potassium-containing salt substitutes or over-the-counter potassium supplements without consulting their physician. If salt substitutes are used concurrently, regular monitoring of serum potassium levels is recommended. Patients should also be advised to seek medical attention if they experience symptoms of hyperkalemia such as weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs.

hydroCHLOROthiazide food
Applies to: Exforge HCT (amlodipine / hydrochlorothiazide / valsartan)
MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.
MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia. Patients should also avoid driving or operating hazardous machinery until they know how the medications affect them.

MONITOR: Calcium-containing products may decrease the effectiveness of calcium channel blockers by saturating calcium channels with calcium. Calcium chloride has been used to manage acute severe verapamil toxicity.
MANAGEMENT: Management consists of monitoring the effectiveness of calcium channel blocker therapy during coadministration with calcium products.

The consumption of grapefruit juice may slightly increase plasma concentrations of amlodipine. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Data have been conflicting and the clinical significance is unknown. Monitoring for calcium channel blocker adverse effects (e.g., headache, hypotension, syncope, tachycardia, edema) is recommended.
