Anyone with some life experience knows that if the color of urine becomes darker, it may be “fire”. In fact, there is another possibility because of taking medicine. Recently, the U.S. “Mayo Clinic” website to introduce you to eat different drugs may make urine into 5 colors. 1, orange. Long-term use of multi-vitamin tablets or multivitamin tablets containing vitamin B2, as well as flavonol, warfarin, Chinese medicine rhubarb and other drugs, will make the urine appear in different shades of yellow or orange. Taking the anti-tuberculosis drug rifampin can cause urine and even sweat to turn orange-red. 2. Brown. Taking sulfonamide antibacterial drugs, dysentery (furazolidone), antimalarial drug chloroquine, senna, etc. can make the urine dark yellow to brown. 3, red. Commonly used in the treatment of chronic constipation of the fruit guide tablets (phenolphthalein tablets) can make the urine turn red or pink, similar to the color of blood urine. In addition, taking the anti-epileptic drug phenytoin sodium, antipsychotic chlorpromazine, antibacterial drug rifampin, etc. can also make the urine red. 4. Black. The use of high-valent iron preparations, taking levodopa, an anti-malarial drug quinine and other drugs commonly used in the treatment of Parkinson’s disease, the urine may appear dark black. 5, blue or green. The diuretic aminoglutethimide causes the urine to fluoresce light blue. With amitriptyline and methylene blue, the urine will turn blue-green. Also note that the abnormal color of urine after taking drugs may also be a sign of adverse drug reactions. For example, long-term heavy use of anti-inflammatory pain (indomethacin) can damage the liver and cause green bilirubinemia and green urine. Changes in urine color during drug use are mostly caused by the products of drug metabolism, and if they are not accompanied by pain and other discomfort, there is no need to worry. However, if the color of urine does not return to normal 2 to 3 days after stopping the medication, you should see a doctor as soon as possible.
