Which medication can have a side effect of causing a yellow-orange discoloration of urine?

Pyridium, also known as Phenazopyridine, is a medication specifically used to relieve urinary pain, burning, irritation, and discomfort. One of the well-known side effects of Pyridium is its ability to cause a yellow-orange discoloration of urine. This effect occurs because Pyridium is a dye that is excreted through the kidneys and can change the color of the urine significantly.

Understanding this side effect is crucial for patient education, as it can help prevent unnecessary concern. Patients may often think there is something wrong when they observe this change in urine color after starting the medication. Being aware of this effect enables healthcare professionals to counsel patients appropriately about what to expect while taking Pyridium, ensuring they are not alarmed by a benign, albeit unusual, side effect. Other medications listed may cause different side effects but do not typically result in the same noticeable change in urine color as Pyridium does.
