Which teaching point is most important for a patient starting rifampin?

• A. Your urine or sweat may become orange in color.
• B. You should avoid sunlight while taking rifampin.
• C. Rifampin can cause permanent hair color change to blue.
• D. Take with meals to prevent nausea.

Answer: (A)

Starting rifampin, the most important teaching point is that urine, sweat, and tears can turn orange-red. This change is harmless and will occur with therapy, so telling the patient upfront prevents alarm and supports adherence. It can stain clothing and even contact lenses, so they should expect it and plan accordingly. This effect helps identify that the drug is in use, but it doesn’t indicate toxicity. Other statements are not accurate: taking rifampin with meals can reduce absorption, so it’s not advised to prevent nausea; it does not cause permanent blue hair color.
