The most common adverse effect is loss of seminal emission. This seems to be caused by<unk> 's high selectivity for α1A receptors. Other common adverse effects (in more than 1% of patients) are dizziness, orthostatic hypotension, diarrhoea, and clogged nose. Less common (0.1–1%) are tachycardia (fast heartbeat), dry mouth, nausea, skin reactions, and erectile dysfunction. Hypersensitivity reactions occur in fewer than 0.01% of patients. There have been reports about intraoperative floppy iris syndrome during cataract extractions. These side effects are similar to those of other α1 antagonists.
