Yes, Benadryl (diphenhydramine), especially when used in large doses or over a long period of time, can potentially cause blood in your urine, a condition known medically as hematuria. While this is not a common side effect, it can occur due to various factors. One possible reason is that Benadryl might cause kidney dysfunction in some individuals, which could result in hematuria. Additionally, it could also be related to other urinary tract issues or complications. However, blood in the urine could have many other causes, and someone experiencing this symptom should seek medical attention promptly to determine the exact cause.
