What color change can Rifampin cause in body fluids?

1. Red-orange

2. Green

3. Blue

4. Yellow

The correct answer is: Red-orange

Rifampin is known to cause a distinctive color change in body fluids, primarily resulting in a red-orange hue. This pigmentation occurs due to the drug's chemical properties and its ability to stain various fluids such as urine, sweat, tears, and saliva. The alteration is not harmful and is a common side effect of rifampin treatment, particularly among individuals taking the medication for conditions like tuberculosis. Aside from this red-orange coloring, other colors mentioned, such as green, blue, or yellow, are not associated with rifampin. These colors may be indicative of different medications or conditions but do not pertain to the effects of rifampin on body fluids. Understanding this side effect is crucial for patients to accurately interpret changes in their body fluids and to avoid unnecessary concern over these harmless alterations.
