| Management | Caution is recommended if alfuzosin is used in combination with other drugs that can prolong the QT interval. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope. If taking drugs that also cause CNS or orthostatic effects (e.g., psychotropic drugs like tricyclic antidepressants, phenothiazines, and neuroleptics), patients should be made aware of the possibility of additive effects with alfuzosin and counseled to avoid activities requiring mental alertness until they know how these agents affect them. | ||||||||
