Cardura XL FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

The incidence of adverse events was derived from two controlled efficacy and safety trials involving 1473 BPH patients. In Study 1, CARDURA XL (doxazosin mesylate extended release tablets) (n=317) was compared to doxazosin IR tablets (n=322) and to placebo (n=156). In Study 2, CARDURA XL (doxazosin mesylate extended release tablets) (n=350) was compared just to doxazosin IR tablets (n=330). In both these studies, CARDURA XL (doxazosin mesylate extended release tablets) was initiated at a dose of 4 mg, which could be increased by the investigator to 8 mg after seven weeks if an adequate response was not seen (see CLINICAL PHARMACOLOGY; Clinical Studies). Similarly, doxazosin IR was begun at a dose of 1 mg, which was increased in all patients to 2 mg after 1 week, followed by the option to increase to 4 mg after 4 weeks, and 8 mg after 7 weeks.

In these two studies, 6% of patients receiving CARDURA XL (doxazosin mesylate extended release tablets) withdrew from the study due to adverse events, compared to 7% receiving doxazosin IR, and 3% receiving placebo. The most commonly reported adverse events leading to discontinuation in the CARDURA XL (doxazosin mesylate extended release tablets) group were: dizziness, dyspnea, asthenia, headache, hypotension, postural hypotension, and somnolence.

The incidence rates presented below (Table 4) are based on combined data from the two controlled studies (Studies 1 and 2). Adverse events with an incidence in the CARDURA XL (doxazosin mesylate extended release tablets) group of at least 1% and reported more frequently than with placebo are summarized in Table 4.
