furosemide ↔ hydrochlorothiazide
Applies to:Lasix (furosemide) and Microzide (hydrochlorothiazide)
MONITOR: The combination of a thiazide and loop diuretic may produce additive or synergistic effects on diuresis and excretion of electrolytes including sodium, potassium, magnesium, and chloride. Although these agents may be combined therapeutically in some patients with inadequate response to a single agent, the increased risk of dehydration, hypotension, hypokalemia, hypomagnesemia, and hyponatremia should be recognized. The exact mechanism of interaction is unclear but appears to be pharmacodynamic rather than pharmacokinetic.
MANAGEMENT: Caution is advised during concomitant use of a thiazide and loop diuretic. Dosages should be titrated slowly and carefully, and electrolytes, BUN, fluid status, blood pressure, and renal function should be monitored regularly. Patients should be advised to contact their physician if they experience signs and symptoms of fluid and electrolyte depletion such as dizziness, lightheadedness, dry mouth, thirst, fatigue, weakness, lethargy, muscle cramps, decreased urination, postural hypotension, and tachycardia.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| 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. |
