Applies to:colchicine/probenecid and Demadex (torsemide)
Some investigators suggest that probenecid may acutely decrease the pharmacologic effects of loop diuretics by competitively inhibiting their renal secretion in the proximal tubule. A marked increase in diuresis and natriuresis may then follow due to increased amount of diuretic available at renal acceptor sites once probenecid has been cleared from the urine. In a study of eight normal volunteers, pretreatment with probenecid led to an overall increased response to a 40 mg dose of furosemide, as indicated by a 37% increase in sodium excretion and a 28% increase in urine volume over an eight-hour period. However, others have not corroborated these findings. One study reported no effect of probenecid on either cumulative response or time course of response of bumetanide, while another reported an increase in initial diuretic efficiency of furosemide but no change in cumulative urinary sodium excretion over five hours. No particular intervention is necessary during concomitant therapy with these agents, but clinicians should be aware of the potential for interaction.

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. |
