Warnings
WARNINGS Angioedema of the face, lips, tongue and/or larynx has been reported with oxybutynin.
In some cases, angioedema occurred after the first dose.
Angioedema associated with upper airway swelling may be life-threatening.
If involvement of the tongue, hypopharynx, or larynx occurs, oxybutynin should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided.
In some cases, angioedema occurred after the first dose.
Angioedema associated with upper airway swelling may be life-threatening.
If involvement of the tongue, hypopharynx, or larynx occurs, oxybutynin should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided.
Adverse Reactions
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 5-20 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 (5-20 mg/day) The most common adverse events reported by patients receiving oxybutynin chloride 5-20 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.
Infections and Infestations: nasopharyngitis, upper respiratory tract infection, bronchitis, cystitis, fungal infection; Metabolism and Nutrition Disorders: fluid retention; Psychiatric Disorders: confusional state; Nervous System Disorders: dysgeusia, sinus headache; Eye Disorders: keratoconjunctivitis sicca, eye irritation; Cardiac Disorders: palpitations, sinus arrhythmia; Vascular Disorders: flushing; Respiratory, Thoracic and Mediastinal Disorders: nasal dryness, cough, pharyngolaryngeal pain, dry throat, sinus congestion, hoarseness, asthma, nasal congestion; Gastrointestinal Disorders: diarrhea, abdominal pain, loose stools, flatulence, vomiting, abdominal pain upper, dysphagia, aptyalism, eructation, tongue coated; Skin and Subcutaneous Tissue Disorders: dry skin, pruritis; Musculoskeletal and Connective Tissue Disorders: back pain, arthralgia, pain in extremity, flank pain; Renal and Urinary Disorders: dysuria, pollakiuria; General Disorders and Administration Site Conditions: fatigue, edema peripheral, asthenia, pain, thirst, edema; Investigations: blood pressure increased, blood glucose increased, blood pressure decreased; Injury, Poisoning, and Procedural Complications: fall.
Postmarketing Surveillance Because postmarketing adverse events 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.
The following additional adverse events have been reported from worldwide postmarketing experience with oral oxybutynin chloride: Psychiatric Disorders: psychotic disorder, agitation, hallucination, memory impairment; Nervous System Disorders: convulsions; Eye Disorders: cycloplegia, mydriasis, glaucoma; Cardiac Disorders: tachycardia, QT interval prolongation, chest discomfort; Gastrointestinal Disorders: decreased gastrointestinal motility, frequent bowel movements; Skin and Subcutaneous Tissue Disorders: rash, decreased sweating; Renal and Urinary Disorders: impotence; Reproductive System and Breast Disorders: suppression of lactation; General Disorders and Administration Site Conditions: hypersensitivity reactions, including angioedema with airway obstruction, urticaria, and face edema; rare anaphylactic reactions requiring hospitalization for emergency treatment; Metabolism and Nutrition Disorders: anorexia; Respiratory, Thoracic and Mediastinal Disorders: dysphonia.
