ADVERSE REACTIONS The safety and efficacy of oxybutynin chloride was evaluated in a total of 199 patients in three clinical trials. These participants were treated with oxybutynin chloride 5 to 20 mg/day for up to 6 weeks. Table 3 shows the incidence of adverse events judged by investigators to be at least possibly related to treatment and reported by at least 5% of patients. Table 3 Incidence (%) of Adverse Events Reported by ≥ 5% of Patients Using Oxybutynin Chloride (5 to 20 mg/day) Body System Adverse Event Oxybutynin Chloride (5 to 20 mg/day) (n=199) Infections and Infestations Urinary tract infection 6.5% Psychiatric Disorders Insomnia Nervousness 5.5% 6.5% Nervous System Disorders Dizziness Somnolence Headache 16.6% 14.0% 7.5% Eye Disorders Blurred vision 9.6% Gastrointestinal Disorders Dry mouth Constipation Nausea Dyspepsia 71.4% 15.1% 11.6% 6.0% Renal and Urinary Disorders Urinary Hesitation Urinary Retention 8.5% 6.0% The most common adverse events reported by patients receiving oxybutynin chloride 5 to 20 mg/day were the expected side effects of anticholinergic agents. The incidence of dry mouth was dose-related. In addition, the following adverse events were reported by 1 to < 5% of patients using oxybutynin chloride (5 to 20 mg/day) in all studies.
