PREPARATIONS: Extended release table:, 10 mg.
STORAGE: Alfuzosin should be stored at room temperature, from 15 C to 30 C (59 F - 86 F).
DOSING: Alfuzosin is taken once daily, immediately after the same meal each day. Tablets should not be chewed or crushed.
DRUG INTERACTIONS: Alfuzosin should not be combined with ketoconazole (Nizoral, Extina, Xolegel, Kuric), itraconazole (Sporanox), or ritonavir (Norvir), because they increase alfuzosin blood levels by preventing the breakdown of alfuzosin by the liver. Combining alfuzosin with blood pressure reducing medications may increase the risk of hypotension (low blood pressure). PDE-5 inhibitors used primarily for erectile dysfunction (for example, vardenafil [Levitra, Staxyn], tadalafil [Cialis, Adcirca], and sildenafil [Viagra, Revatio]) add to the blood pressure lowering effects of alfuzosin and may result in orthostatic or postural hypotension. (See Side Effects.)
PREGNANCY: Alfuzosin is not used by women; however, studies in animals have shown no evidence of fetal toxicity, even with exceedingly high doses of alfuzosin.
NURSING MOTHERS: Alfuzosin is not prescribed for women.
