Rifampin can cause a notable discoloration of bodily fluids. Which option reflects this effect?

• A. Blue sclera
• B. Pink tears
• C. Hair whitening
• D. Nausea

Answer: (B)

Rifampin contains a vivid pigment that can color body fluids. When the drug is excreted into tears, this pigment can tint the tears a pinkish or orange hue. This is a known, harmless discoloration that can also stain contact lenses or clothing. The other options don’t reflect this pigment-related effect—blue sclera isn’t caused by rifampin, hair whitening isn’t a typical rifampin effect, and nausea is a side effect but not a color change.
