Can diltiazem hydrochloride cause blood in the urine?

Diltiazem hydrochloride is a calcium channel blocker primarily used to treat hypertension and certain heart conditions. While blood in the urine (hematuria) is not a common side effect of diltiazem, it can occur in rare cases due to hypersensitivity reactions or interactions with other medications. If you experience blood in your urine while taking diltiazem, it's important to consult a healthcare professional for further evaluation.
