What notable side effect can occur from antitubercular medications?

Antitubercular medications, specifically rifampin, can cause a reddish-orange discoloration of bodily fluids, such as urine, sweat, tears, and saliva. This is a known side effect and is due to the drug's chemical properties. The discoloration is harmless and results from the elimination of the drug from the body. Understanding this side effect is crucial for healthcare providers, as it helps in counseling patients about what to expect during treatment and in alleviating potential concerns regarding the color change of these bodily fluids. This informative awareness can enhance patient compliance and overall treatment adherence by ensuring that patients are not alarmed by these changes.
