What color does the urine turn when taking rifampin and pyridium?

Rifampin and pyridium are known for causing changes in urine color due to their chemical properties. When rifampin is ingested, it is metabolized and excreted in the urine, resulting in a distinct orange coloration. Pyridium, also known as phenazopyridine, is a urinary analgesic that also colors the urine orange.

Both medications exert their color-changing effects by altering the pigments in the urine, and the combination of these two drugs enhances the intensity of the orange coloration. This phenomenon is well-documented and is an important consideration for patients to be aware of, as it can be mistaken for hematuria (blood in the urine) if they are not informed about the potential side effects of their medications.

Thus, the appropriate answer indicating the urine color when taking rifampin and pyridium is orange.
