MONITOR: Concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) and diuretics may adversely affect renal function due to NSAID inhibition of the renal synthesis of prostaglandins that help maintain renal perfusion in dehydrated states. The risk may be increased in patients on dietary sodium restriction. At the same time, hypotensive effect of the diuretics may be reduced because inhibition of prostaglandins can lead to unopposed pressor activity and, consequently, elevation in blood pressure. Natriuretic and diuretic effects may also be reduced, as NSAIDs have been reported to cause sodium and water retention, which may account for the increased risk of congestive heart failure associated with the combination. One study showed an increase in the incidence density of congestive heart failure (in patients over 55 years of age) from 9.3 per 1,000 person-years in patients on diuretics to 23.3 per 1,000 person-years in patients on both diuretic and NSAID therapy. NSAIDs may also increase the risk of hyperkalemia associated with potassium-sparing diuretics.

MANAGEMENT: In patients receiving both diuretic and NSAID therapy, management consists of avoiding dehydration and carefully monitoring the patient's renal function and blood pressure. If renal insufficiency or hyperkalemia develops, both drugs should be discontinued until the condition is corrected.

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.

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

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.
