There is no direct, documented interaction between Voxitin 5 (vortioxetine) and Dilzem CD 120 (diltiazem). However, caution is advised because diltiazem affects heart rhythm and blood pressure, while vortioxetine can influence liver enzymes and occasionally impact cardiovascular function. Individual responses can vary, and other health conditions or medications may affect safety. Therefore, you should always consult your doctor before taking these medications together to ensure it is safe for your specific situation.
