Rifampin is a prescription medication that is used to treat a variety of bacterial infections, including tuberculosis, meningitis, and leprosy. It is a member of the rifamycin class of antibiotics, which are known for their ability to inhibit the synthesis of bacterial DNA and RNA.

One notable side effect of rifampin is that it can turn urine orange or red in color. This is due to the metabolism of the medication, which causes it to be broken down into its active form, rifampicin. Rifampicin is a red-orange pigment that is excreted in the urine, giving it a distinctive color.

The orange color of urine caused by rifampin is not a cause for concern and is considered a normal side effect of the medication. It does not indicate an overdose or adverse reaction to the medication.

It is worth noting that rifampin can also turn other body fluids and secretions, such as sweat and tears, a reddish color. It can also cause contact lenses to change color or become discolored. These side effects are also considered normal and do not pose a health risk.

In conclusion, rifampin is a medication that is used to treat a variety of bacterial infections. One notable side effect of rifampin is that it can turn urine orange or red in color due to the metabolism of the medication. The orange color of urine caused by rifampin is a normal side effect of the medication and does not pose a health risk.
