Hello! Are you currently taking Rifampin? This drug discolors secretions, such as your sweat, tears and urine to an orange, red or brown color. I realize that most meds suggest that you avoid alcohol, but this one really means it. Labs must be checked regularly while on this medication.
If you wear contacts, consider disposable contact lenses. https://www.webmd.com/drugs/2/drug-1744/rifampin-oral/details
