* Eyes: People taking<unk>  are prone to a complication known as floppy iris syndrome during cataract surgery. Adverse outcomes of the surgery are greatly reduced by the surgeon's prior knowledge of the person's history with this drug, and thus having the option of alternative techniques. * Severe hypotension. * Persons with cardiac conditions including hypotension, mechanical heart failure (valvular, pulmonary embolism, pericarditis), and congestive heart failure should be monitored carefully while taking<unk> . * Alpha blockers, including prazosin, terazosin, doxazosin, or<unk> , do not appear to affect all-cause mortality in heart failure re-hospitalization in those also receiving β-blockers.<unk>  can also cause retrograde ejaculation, which occurs when semen is redirected to the urinary bladder instead of being ejaculated normally. This is because<unk>  relaxes the muscles of the urethral sphincters, which are normally closed during ejaculation. This side effect can be mitigated by regular pelvic floor (Kegel) exercise and contracting the pelvic floor during ejaculation.
