Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Angina: Alfuzosin may cause increased heart rate or decreased blood pressure, which may affect control of angina symptoms. People with angina (chest pain) should stop using this medication if their symptoms reappear or become worse.
Cataracts: If you will be undergoing cataract surgery, tell your doctor that you are taking a medication that contains alfuzosin. Your surgeon may advise you to temporarily stop taking the medication before the surgery.
Orthostatic hypotension (low blood pressure upon arising): Alfuzosin can cause orthostatic hypotension, leading to dizziness or fainting when rising from a sitting or lying down position. If you feel faint or dizzy when getting up, lie down until the symptoms pass. This effect often goes away as treatment with alfuzosin is continued. People with orthostatic hypotension should use caution while taking alfuzosin, as it may worsen their condition.
Prostate cancer: Prostate cancer and BPH (benign prostatic hyperplasia) cause many of the same symptoms. These two diseases frequently coexist. Before starting alfuzosin therapy, an evaluation should take place to rule out prostate cancer.
QT prolongation: This medication can lengthen heartbeat as shown on an electrocardiogram test, also known as QT prolongation. If you have heart disease and abnormal heart rhythms, or are taking certain medications (e.g., verapamil, atazanavir), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you develop heart palpitations (fast or irregular heartbeat) or experience fainting spells, stop taking ciprofloxacin and contact your doctor immediately.
Women: Alfuzosin is not recommended for use by women.
Children: Alfuzosin is not recommended for use by children.
