Introduction

Some medications contain pigments or metabolites that can change the color of urine. For example, riboflavin (vitamin B2) in the B-complex vitamins may cause urine to appear bright yellow after being excreted through the kidneys. This phenomenon is a normal drug reaction and poses no harm to the body; urine color will gradually return to normal after discontinuation of the medication. If the medication does not contain such ingredients or if the individual maintains adequate water intake, the change in urine color may be less noticeable due to dilution.

Generally speaking, taking medication may or may not cause yellow urine, mainly depending on the drug's composition and individual factors. If concerned, it is advisable to consult a healthcare professional in advance. Detailed explanations are as follows:

Some medications contain pigments or metabolic byproducts that can change the urine color. For example, riboflavin (a B vitamin), after being excreted through the kidneys following ingestion, may cause the urine to appear bright yellow. This phenomenon is a normal drug reaction and poses no harm to the body; the urine color typically returns to normal gradually after discontinuation of the medication.

If the medication does not contain such ingredients or if the individual maintains sufficient water intake, the urine may become diluted, resulting in less noticeable color changes. In such cases, yellow urine may not occur. Additionally, if yellow urine is accompanied by symptoms such as frequent urination or painful urination, it may not be drug-related and could indicate other underlying issues.

If yellow urine appears after taking medication, you can first check the drug's package insert to see whether such an effect is listed. If discomfort is experienced or the urine color remains abnormal, prompt medical consultation and examination are recommended to determine the cause and receive appropriate treatment.
