Adverse Reactions
6 ADVERSE REACTIONS The most common (incidence ≥5%) adverse reactions were dry mouth, constipation, diarrhea, headache, somnolence, and dizziness.

The safety and efficacy of oxybutynin chloride extended-release tablets (5 to 30 mg/day) was evaluated in 774 adult subjects who participated in five double-blind, controlled clinical trials. In four of the five studies, oxybutynin IR (5 to 20 mg/day in 199 subjects) was an active comparator. Adverse reactions reported by ≥ 1% of subjects are shown in Table 1. Table 1: Adverse Drug Reactions Reported by ≥ 1% of Oxybutynin Chloride Extended-Release Tablets-treated Adult Subjects in Five Double-blind, Controlled Clinical Trials of Oxybutynin Chloride Extended-Release Tablets System/Organ Class Preferred Term Oxybutynin Chloride Extended-Release Tablets 5 to 30 mg/day n = 774 % Oxybutynin IR IR = immediate release 5 to 20 mg/day n = 199 % Psychiatric Disorders Insomnia 3.0 5.5 Nervous System Disorders Headache 7.5 8.0 Somnolence 5.6 14.1 Dizziness 5.0 16.6 Dysgeusia 1.6 1.5 Eye Disorders Vision blurred 4.3 9.6 Dry eye 3.1 2.5 Respiratory, Thoracic and Mediastinal Disorders Cough 1.9 3.0 Oropharyngeal pain 1.9 1.5 Dry throat 1.7 2.5 Nasal dryness 1.7 4.5 Gastrointestinal Disorders Dry mouth 34.9 72.4 Constipation 8.7 15.1 Diarrhea 7.9 6.5 Dyspepsia 4.5 6.0 Nausea 4.5 11.6 Abdominal pain 1.6 2.0 Vomiting 1.3 1.5 Flatulence 1.2 2.5 Gastro-esophageal reflux disease 1.0 0.5 Skin and Subcutaneous Tissue Disorders Dry skin 1.8 2.5 Pruritus 1.3 1.5 Renal and Urinary Disorders Dysuria 1.9 2.0 Urinary hesitation 1.9 8.5 Urinary retention 1.2 3.0 General Disorders and Administration Site Conditions Fatigue 2.6 3.0 Investigations Residual urine volume The bundled term residual urine volume consists of the preferred terms residual urine volume and residual urine volume increased. 2.3 3.5 The discontinuation rate due to adverse reactions was 4.4% with oxybutynin chloride extended-release tablets compared to 0% with oxybutynin IR. The most frequent adverse reaction causing discontinuation of study medication was dry mouth (0.7% ). The following adverse reactions were reported by <1% of oxybutynin chloride extended-release tablets-treated patients and at a higher incidence than placebo in clinical trials: Metabolism and Nutrition Disorders: anorexia, fluid retention; Vascular disorders: hot flush; Respiratory, thoracic and mediastinal disorders: dysphonia; Gastrointestinal Disorders: dysphagia, frequent bowel movements; General disorders and administration site conditions: chest discomfort, thirst. 6.2 Postmarketing Experience The following additional adverse reactions have been reported from worldwide postmarketing experience with oxybutynin chloride extended-release tablets. Because postmarketing reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Infections and Infestations: Urinary tract infection; Psychiatric Disorders: psychotic disorder, agitation, confusional state, hallucinations, memory impairment, abnormal behavior; Nervous System Disorders: convulsions; Eye Disorders: glaucoma; Respiratory, Thoracic and Mediastinal Disorders: nasal congestion; Cardiac Disorders: arrhythmia, tachycardia, palpitations, QT interval prolongation; Vascular Disorders: flushing, hypertension; Skin and Subcutaneous Tissue Disorders: rash; Renal and Urinary Disorders: impotence; General Disorders and Administration Site Conditions: hypersensitivity reactions, including angioedema with airway obstruction, urticaria, and face edema; anaphylactic reactions requiring hospitalization for emergency treatment; Injury, poisoning and procedural complications: fall. Additional adverse events reported with some other oxybutynin chloride formulations include: cycloplegia, mydriasis, and suppression of lactation.In one reported case, concomitant use of oxybutynin with carbamazepine and dantrolene was associated with adverse events of vomiting, drowsiness, confusion, unsteadiness, slurred speech and nystagmus, suggestive of carbamazepine toxicity.
Information for Patients
17 PATIENT COUNSELING INFORMATION Patients should be informed that oxybutynin may produce angioedema that could result in life threatening airway obstruction. Patients should be advised to promptly discontinue oxybutynin therapy and seek immediate medical attention if they experience swelling of the tongue, edema of the laryngopharynx, or difficulty breathing. Patients should be informed that anticholinergic (antimuscarinic) agents such as oxybutynin chloride extended-release tablets, may produce clinically significant adverse reactions related to anticholinergic activity such as: Urinary retention and constipation Heat prostration due to decreased sweating. Heat prostration can occur when anticholinergic medicines are administered in the presence of high environmental temperature. Patients should be informed that anticholinergic medicines such as oxybutynin chloride extended-release tablets may produce drowsiness (somnolence), dizziness or blurred vision. Patients should be advised to exercise caution in decisions to engage in potentially dangerous activities until oxybutynin chloride extended-release tablets effects have been determined. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin chloride extended-release tablets. Patients should be informed that oxybutynin chloride extended-release tablets should be swallowed whole with the aid of liquids. Patients should not chew, divide, or crush tablets. Oxybutynin chloride extended-release tablets should be taken at approximately the same time each day.
