What color change might be observed in body fluids due to rifampin use?

• A. Bright yellow
• B. Greenish-blue
• C. Reddish-orange
• D. Pale white

Answer: (C)

Rifampin, an antibiotic used primarily to treat tuberculosis and other bacterial infections, is known for its distinctive effect on body fluids. When rifampin is metabolized, it can lead to a notable change in the color of various body fluids, most noticeably urine, sweat, saliva, and tears. The correct observation is that these fluids may turn a reddish-orange hue. This pigmentation is due to the drug's chemical structure and how it is excreted from the body. The reddish-orange color can serve as a visual indicator of the drug's presence in the body, but it does not indicate toxicity or any adverse effect; it is simply a characteristic of rifampin. Understanding this side effect is important for patient education, as it helps to differentiate the color change caused by the medication from other potential medical issues or side effects.
