Does Compton Change Urine Color?

Rifampin, a component of Compton, causes orange discoloration of urine and other body fluids. 1

Understanding Rifampin's Effect on Urine Color

Rifampin (also known as rifampicin), which is a rifamycin derivative used in tuberculosis treatment, is known to cause discoloration of body fluids. According to the American Thoracic Society and CDC guidelines, rifampin is excreted in urine, tears, sweat, and other body fluids and colors them orange 1. This is an expected side effect that patients should be informed about when starting treatment.

The guidelines specifically state that patients should be advised about:

• Discoloration of body fluids (orange color)
• Possible permanent discoloration of soft contact lenses

Mechanism and Clinical Significance

The orange discoloration of urine occurs because:

• Rifampin is metabolized by the liver
• Approximately 25% of the drug is not protein-bound and circulates freely
• The drug and its metabolites are excreted through the kidneys into the urine
• The inherent color of the drug compounds causes the characteristic orange discoloration

This color change:

• Is not harmful or indicative of toxicity
• Begins shortly after starting treatment
• Persists throughout the duration of therapy
• Resolves after discontinuation of the medication

Other Medications That Affect Urine Color

It's important to note that changes in urine color can be caused by various factors, including medications, foods, and pathological conditions 2, 3, 4. When evaluating abnormal urine color, clinicians should consider:

• Medications (like rifampin, propofol which can cause green urine 5)
• Foods and dietary supplements
• Hydration status
• Underlying medical conditions

Patient Education Points

When prescribing Compton containing rifampin, healthcare providers should:

1. Inform patients about the expected orange discoloration of urine and other body fluids
2. Reassure patients that this is a normal, harmless side effect
3. Advise that the discoloration will persist throughout treatment
4. Warn about potential staining of contact lenses
5. Distinguish this expected color change from other potentially concerning urine color changes

Conclusion

The orange discoloration of urine caused by rifampin in Compton is a well-documented, benign side effect that patients should be informed about prior to starting treatment. This knowledge helps prevent unnecessary concern when patients notice the color change and distinguishes it from potentially pathological causes of abnormal urine color.
