Salicylates in anti-inflammatory dosages may blunt the diuretic and natriuretic response to loop diuretics. The interaction has been demonstrated in patients with ascites secondary to liver cirrhosis and in normal volunteers. Investigators theorize that salicylates may inhibit the renal effects of loop diuretics that are mediated by prostaglandins, including increases in sodium excretion, renal blood flow, and plasma renin activity. Since renal prostaglandins are believed to play a major role in the maintenance of renal blood flow and glomerular filtration rate in cirrhotics with ascites, the interaction may be particularly important in this population. No clinical interventions are generally required, but the possibility of a potential interaction should be considered in patients with ascites treated with a loop diuretic and salicylate or salicylate-related product.

Drug and food interactions

Moderate

furosemide food

Applies to: Lo-Aqua (furosemide)

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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 interaction information available.
