Who should not take it
Alfuzosin hydrochloride extended-release tablets are contraindicated for use: in patients with moderate or severe hepatic impairment (Childs-Pugh categories B and C), since alfuzosin blood levels are increased in these patients [ see Use in Specific Populations ( 8.7 ) and Clinical Pharmacology ( 12.3) ]. with potent CYP3A4 inhibitors such as ketoconazole, itraconazole, and ritonavir, since alfuzosin blood levels are increased [ see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 ) ]. in patients with known hypersensitivity, such as urticaria and angioedema, to alfuzosin hydrochloride or any component of alfuzosin hydrochloride extended-release tablets [ see Adverse Reactions ( 6.2 ) ] Moderate or severe hepatic impairment ( 4 , 8.7 , 12.3 ) Co-administration with potent CYP3A4 inhibitors (e.g. ketoconazole, itraconazole, ritonavir) ( 4 , 5.4 , 7.1 , 12.3 ) Known hypersensitivity (e.g., urticaria or angioedema) to alfuzosin or any of the ingredients ( 4 , 6.2 )
Warnings and cautions
Postural hypotension/syncope: Care should be taken in patients with symptomatic hypotension or who have had a hypotensive response to other medications or are concomitantly treated with antihypertensive medication or nitrates ( 5.1 ) Use with caution in patients with severe renal impairment (creatinine clearance <30 mL/min) ( 5.2 , 8.6 , 12.3 ) Use with caution in patients with mild hepatic impairment ( 5.3 , 8.7 , 12.3 ) Should not be used in combination with other alpha adrenergic antagonists ( 5.4 , 7.2 ) Prostate carcinoma should be ruled out prior to treatment ( 5.5 ) Intraoperative Floppy Iris Syndrome (IFIS) during cataract surgery may require modifications to the surgical technique ( 5.6) Discontinue alfuzosin hydrochloride extended-release tablets if symptoms of angina pectoris appear or worsen ( 5.8 ) Use with caution in patients with a history of QT prolongation or who are taking medications which prolong the QT interval ( 5.9 , 12.2 ) 5.1 Postural Hypotension Postural hypotension with or without symptoms (e.g., dizziness) may develop within a few hours following administration of alfuzosin hydrochloride extended-release tablets. As with other alpha-adrenergic antagonists, there is a potential for syncope. Patients should be warned of the possible occurrence of such events and should avoid situations where injury could result should syncope occur. There may be an increased risk of hypotension/postural hypotension and syncope when taking alfuzosin hydrochloride extended-release tablets concomitantly with anti-hypertensive medication and nitrates. Care should be taken when alfuzosin hydrochloride extended-release tablets are administered to patients with symptomatic hypotension or patients who have had a hypotensive response to other medications. 5.2 Patients with Renal Impairment Caution should be exercised when alfuzosin hydrochloride extended-release tablets are administered in patients with severe renal impairment (creatinine clearance < 30 mL/min) [ see Use in Specific Populations ( 8.6) and Clinical Pharmacology ( 12.3) ].

Reported side effects
Most common adverse reactions in clinical studies (incidence ≥2% and at a higher incidence than placebo): dizziness, upper respiratory tract infection, headache, fatigue. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Apotex Corp. at 1-800- 706-5575 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The incidence of adverse reactions has been ascertained from 3 placebo-controlled clinical trials involving 1,608 men where daily doses of 10 and 15 mg alfuzosin were evaluated. In these 3 trials, 473 men received alfuzosin hydrochloride 10 mg extended-release tablets. In these trials, 4% of patients taking alfuzosin hydrochloride 10 mg extended-release tablets withdrew from the trial due to adverse reactions, compared with 3% in the placebo group. Table 1 summarizes adverse reactions that occurred in ≥2% of patients receiving alfuzosin hydrochloride extended-release tablets, and at a higher incidence than that of the placebo group. In general, the adverse reactions seen in long-term use were similar in type and frequency to the events described below for the 3-month trials. […]
Interactions with other medicines
Concomitant use of PDE5 inhibitors with alpha adrenergic antagonists, including alfuzosin hydrochloride extended-release tablets, can potentially cause symptomatic hypotension ( 5.4 , 7.4) 7.1 CYP3A4 Inhibitors Alfuzosin hydrochloride extended-release tablets are contraindicated for use with potent CYP3A4 inhibitors such as ketoconazole, itraconazole, or ritonavir, since alfuzosin blood levels are increased [see Contraindications ( 4 ), Warnings and Precautions ( 5.4) and Clinical Pharmacology ( 12.3) ]. 7.2 Alpha Adrenergic Antagonists The pharmacokinetic and pharmacodynamic interactions between alfuzosin hydrochloride extended-release tablets and other alpha-adrenergic antagonists have not been determined. However, interactions may be expected, and alfuzosin hydrochloride extended-release tablets should not be used in combination with other alpha adrenergic antagonists [see Warnings and Precautions ( 5.4) ]. 7.3 Antihypertensive Medication and Nitrates There may be an increased risk of hypotension/postural hypotension and syncope when taking alfuzosin hydrochloride extended-release tablets concomitantly with anti-hypertensive medication and nitrates [see Warnings and Precautions ( 5.1) ]. 7.4 PDE5 Inhibitors Caution is advised when alpha adrenergic antagonists, including alfuzosin hydrochloride extended-release tablets, are co-administered with PDE5 inhibitors. Alpha adrenergic antagonists and PDE5 inhibitors are both vasodilators that can lower blood pressure. Concomitant use of these two drug classes can potentially cause symptomatic hypotension [ see Warnings and Precautions ( 5.4) ]. 7.4 PDE5 Inhibitors Caution is advised when alpha adrenergic antagonists, including alfuzosin hydrochloride extended-release tablets, are co-administered with PDE5 inhibitors. Alpha adrenergic antagonists and PDE5 inhibitors are both vasodilators that can lower blood pressure. Concomitant use of these two drug classes can potentially cause symptomatic hypotension [ see Warnings and Precautions ( 5.4) ].
Use in specific groups
8.1 Pregnancy Risk Summary Alfuzosin hydrochloride extended-release tablets are not indicated for use in women. There are no adequate data on the developmental risk associated with the use of alfuzosin hydrochloride extended-release tablets in pregnant women . Based on findings from animal studies alfuzosin administered during the period of organogenesis was not teratogenic, embryotoxic or fetotoxic at up to 1200 times the MRHD of 10 mg via AUC in rats and 3 times in rabbits, via body surface area. In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancy is 2 to 4% and 15 to 20%, respectively. Data Animal data Alfuzosin was not teratogenic, embryotoxic or fetotoxic in rats at plasma exposure levels (based on AUC of unbound drug) up to 1200 times (maternal oral dose of 250 mg/kg/day) the maximum recommended human dose (MRHD) of 10 mg. In rabbits administered up to 3 times the MRHD (based on body surface area) (maternal oral dose of 100 mg/kg/day) no embryofetal toxicity or teratogenicity was observed. Gestation was slightly prolonged in rats at exposure levels (based on AUC of unbound drug) approximately 12 times (greater than 5 mg/kg/day oral maternal dose) the MRHD, but difficulties with parturition were not observed. 8.2 Lactation Risk Summary Alfuzosin hydrochloride extended-release tablets is not indicated for use in women. There are no data on the presence of alfuzosin hydrochloride extended-release tablets in human milk, the effect on the breastfed child, or effect on milk production. 8.4 Pediatric Use Alfuzosin hydrochloride extended-release tablets are not indicated for use in the pediatric population. Efficacy of alfuzosin hydrochloride was not demonstrated in a randomized, double-blind, placebo-controlled, efficacy and safety trial conducted in 172 patients ages 2 to 16 years with elevated detrusor leak point pressure (LPP≥40 cm H 2 O) of neurologic origin treated with alfuzosin hydrochloride using pediatric formulations. The trial included a 12-week efficacy phase followed by a 40-week safety extension period. […]
If too much is taken
Should overdose of alfuzosin hydrochloride extended-release tablets lead to hypotension, support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in the supine position. If this measure is inadequate, then the administration of intravenous fluids should be considered. If necessary, vasopressors should then be used, and the renal function should be monitored and supported as needed. Alfuzosin is 82% to 90% protein bound; therefore, dialysis may not be of benefit.
