PATIENT INFORMATION ABOUT CARDURA

“How to Take Cardura and What You Should Know While Taking Cardura for BPH"
  • Tell your surgeon if you take or have taken Cardura if you plan to have surgery for cataracts (clouding of the eye). During cataract surgery, a condition called Intraoperative Floppy Iris Syndrome (IFIS) can happen if you take or have taken Cardura.
  • If you use Cardura with an oral erectile dysfunction medicine (phosphodiesterase-5 (PDE-5) inhibitor), it can cause a sudden drop in your blood pressure and you can become dizzy or faint. Talk with your healthcare provider before using PDE-5 inhibitors.
