Diovan (valsartan) Disease Interactions

There are 8 disease interactions with Diovan (valsartan):


Ar Antagonist (Includes Diovan) ↔ Diabetes

Severe Potential Hazard, Moderate plausibility

Applies to: Diabetes Mellitus

The coadministration of some angiotensin II receptor blocker agents with aliskiren is contraindicated in patients with diabetes.


Ar Antagonists (Includes Diovan) ↔ Hypotension

Severe Potential Hazard, High plausibility

Applies to: Dehydration, hemodialysis, Hyponatremia

Angiotensin II receptor (AR) antagonists can cause symptomatic hypotension in patients with an activated renin-angiotensin system, such as volume- and/or sodium-depleted patients. Therapy with AR antagonists should be administered cautiously in such patients and in those predisposed to hypovolemic or hyponatremic states (e.g., patients on diuretic therapy, especially if high doses were used or if recently instituted; those on dietary salt restriction; renal dialysis patients). Volume and/or sodium depletion should be corrected prior to initiating therapy with AR antagonists, and the patient should be hemodynamically stable. Ideally, patients at risk for excessive hypotension should initiate AR antagonist therapy under close medical supervision, preferably with a lower dose, and followed closely for the first 2 weeks of treatment and whenever the dosage of AR antagonist or diuretic is increased.

Ar Antagonists (Includes Diovan) ↔ Angioedema

Moderate Potential Hazard, Moderate plausibility

Applies to: Angioedema

Patients with a history of angioedema may be at increased risk of angioedema while receiving angiotensin II receptor (AR) antagonists. Patients should be advised to immediately report any signs or symptoms suggestive of angioedema (swelling of face, extremities, eyes, lips, or tongue, or difficulty swallowing or breathing) and to stop taking the medication until otherwise directed by their physician. Emergency therapy and/or measures to prevent airway obstruction are required for angioedema involving the tongue, glottis, or larynx. Treatment with angiotensin II receptor (AR) antagonists should be discontinued permanently if angioedema develops in association with therapy.


Ar Antagonists (Includes Diovan) ↔ Chf

Moderate Potential Hazard, Moderate plausibility

Applies to: Congestive Heart Failure

Angiotensin II receptor (AR) antagonists can cause renal impairment in patients whose renal function depends on the activity of the renin-angiotensin-aldosterone system. In addition, symptomatic hypotension can occur in susceptible individuals, which may compromise renal and myocardial perfusion. In patients with severe congestive heart failure (CHF), treatment with AR antagonists has been associated with oliguria and/or progressive azotemia and, rarely, renal failure, myocardial ischemia, and death. Therapy with AR antagonists should be initiated cautiously in patients with severe CHF, especially when accompanied by volume and/or sodium depletion. In patients who experience a decline in renal function, discontinuation of AR antagonist therapy is usually not required provided there is symptomatic improvement of the heart failure and renal deterioration is well-tolerated. Transient hypotension is also not a contraindication to further treatment with AR antagonists, since therapy can usually be reinstated without difficulty after blood pressure stabilizes.

Ar Antagonists (Includes Diovan) ↔ Hyperkalemia

Moderate Potential Hazard, Moderate plausibility

Applies to: Hyperkalemia

Drugs that inhibit the renin-angiotensin, such as angiotensin II receptor antagonist system can cause hyperkalemia. Concomitant use of these agents with drugs that increase potassium levels may increase the risk of hyperkalemia. Use caution when using these agents together and monitor serum potassium periodically.


Ar Antagonists (Includes Diovan) ↔ Renal Artery Stenosis

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Artery Atherosclerosis

In patients with bilateral renal artery stenosis or renal artery stenosis in a solitary kidney, angiotensin II receptor (AR) antagonists may reduce renal perfusion to a critically low level. Increases in serum creatinine or blood urea nitrogen have been reported with ACE inhibitors, a class of drugs that also block the renin-angiotensin-aldosterone system. Although there are no long-term data on the use of AR antagonists in patients with renal artery stenosis, a similar effect should be anticipated. Renal function should be monitored closely for the first few weeks of therapy.

Ar Antagonists (Includes Diovan) ↔ Renal Impairment

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Dysfunction

Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system and by diuretics. Patients whose renal function may depend in part on the activity of the renin-angiotensin system (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion) may be at particular risk of developing acute renal failure with these agents. Monitor renal function periodically in these patients. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function with these agents.


Valsartan (Includes Diovan) ↔ Renal/Liver Disease

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease, Biliary Obstruction, Renal Dysfunction

Valsartan is primarily eliminated by biliary excretion, and a minority is excreted in the urine. Dosage adjustments are not necessary in patients with renal impairment unless they are also volume-depleted, in which case therapy should be initiated under medical supervision. Likewise, patients with mild to moderate hepatic impairment or biliary obstruction generally do not require a dosage adjustment. The manufacturer recommends administering valsartan therapy with caution in patients with impaired renal and/or liver function, particularly if these conditions are severe.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
