When taking rifampin, what statement indicates the patient understands the effects of the medication?

• A. "It can cause my eyes to water excessively."
• B. "I should avoid soft contact lenses."
• C. "It can reduce my blood pressure."
• D. "I can take it at any time during the day."

Answer: (B)

The statement indicating the patient's understanding of the effects of rifampin is that they should avoid soft contact lenses. Rifampin is known to cause orange or reddish discoloration of bodily fluids, including urine, sweat, and tears. This pigmentation can stain soft contact lenses, making them unsuitable for use while on the medication. Patients using soft contact lenses during treatment with rifampin are at risk of damaging their lenses and resulting in visual discomfort due to the staining. The other options do not accurately reflect the effects or recommendations associated with rifampin. While excessive watering of the eyes can occur with certain conditions or medications, it is not a recognized side effect of rifampin. The medication does not specifically reduce blood pressure nor is there a requirement for timing its dose throughout the day; rifampin should be taken consistently as prescribed, either at one particular time or frequency as directed by a healthcare provider.
