🩺 Clinical
Oxybutynin is used to treat overactive bladder (a bladder condition that causes sudden urges to urinate that may be hard to control) and to control bladder muscles weakened in certain nerve conditions. Oxybutynin is in a class of medications called anticholinergics/antimuscarinics. It works by relaxing the bladder muscles.

📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾

⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION Oral Solution Adults: The usual dose is one teaspoon (5 mg/5 mL) of oral solution two to three times a day. The maximum recommended dose is one teaspoon (5 mg/5 mL) of oral solution four times a day. A lower starting dose of 2.5 mg two or three times a day is recommended for the frail elderly.
Pediatric patients over 5 years of age: The usual dose is one teaspoon (5 mg/5 mL) of oral solution two times a day. The maximum recommended dose is one teaspoon (5 mg/5mL) of oral solution three times a day.
⛔ Contraindications ▾
CONTRAINDICATIONS Oxybutynin chloride is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. Oxybutynin chloride is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS The safety and efficacy of oxybutynin chloride was evaluated in a total of 199 patients in three clinical trials comparing oxybutynin chloride with oxybutynin chloride (see Table 3). 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 5.5% Nervousness 6.5% Nervous System Disorders Dizziness 16.6% Somnolence 14.0% Headache 7.5% Eye Disorders Blurred vision 9.6% Gastrointestinal Disorders Dry mouth 71.4% Constipation 15.1% Nausea 11.6% Dyspepsia 6.0% Renal and Urinary Disorders Urinary Hesitation 8.5% Urinary Retention 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. 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 oxybutynin chloride: Psychiatric Disorders : psychotic disorder, agitation, hallucinations; Nervous System Disorders : convulsions; Eye disorders : cycloplegia, mydriasis; Cardiac Disorders : tachycardia; Gastrointestinal Disorders : decreased gastrointestinal motility; Skin and Subcutaneous Tissue Disorders : rash, decreased sweating; Renal and Urinary Disorders : impotence; Reproductive system and breast disorders : Suppression of lactation.
🆘 Overdosage ▾
OVERDOSAGE Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered. Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation (e.g., restlessness, tremor, irritability, convulsions, delirium, hallucinations), flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention.
Other symptoms may include hypotension or hypertension, respiratory failure, paralysis, and coma. Ingestion of 100 mg oxybutynin chloride in association with alcohol has been reported in a 13-year-old boy who experienced memory loss, and a 34 year old woman who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients fully recovered with symptomatic treatment.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects).
Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin chloride increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination.
Antimuscarinic activity resides predominately in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. Pharmacokinetics Absorption Following oral administration of oxybutynin chloride oral solution, oxybutynin is rapidly absorbed achieving C max within an hour, following which plasma concentration decreases with an effective half-life of approximately 2 to 3 hours.
The absolute bioavailability of oxybutynin is reported to be about 6% (range 1.6 to 10.9%). Wide interindividual variation in pharmacokinetic parameters is evident following oral administration of oxybutynin. The mean pharmacokinetic parameters for R- and S-oxybutynin are summarized in Table 1.
The plasma concentration-time profiles for R- and S-oxybutynin are similar in shape; Figure 1 shows the profile for R-oxybutynin. Table 1 Mean (SD) R- and S-Oxybutynin Pharmacokinetic Parameters Following Three Doses of Oxybutynin Chloride 5 mg Administered every 8 Hours (n=23) Parameters (units) R-Oxybutynin S-Oxybutynin C max (ng/mL) 3.6 (2.2) 7.8 (4.1) T max (h) 0.89 (0.34) 0.65 (0.32) AUC t (ng.h/mL) 22.6 (11.3) 35.0 (17.3) AUC inf (ng.h/mL) 24.3 (12.3) 37.3 (18.7) Figure 1 . Mean R-oxybutynin plasma concentrations following three doses of Oxybutynin Chloride 5 mg administered every 8 hours for 1 day in 23 healthy adult volunteers Oxybutynin chloride steady-state pharmacokinetics were also studied in 23 pediatric patients with detrusor overactivity associated with a neurological condition (e.g., spina bifida).
These pediatric patients were on oxybutynin chloride oral solution (n=12) with total daily dose ranging from 5 mg to 22.5 mg (0.26 to 0.75 mg/kg). Overall, most patients (86.9%) were taking a total daily oxybutynin chloride dose between 10 mg and 15 mg. Sparse sampling technique was used to obtain serum samples.
When all available data are normalized to an equivalent of 5 mg twice daily oxybutynin chloride, the mean pharmacokinetic parameters derived for R- and S-oxybutynin and R- and S-desethyloxybutynin are summarized in Table 2b (for oral solution). The plasma-time concentration profiles for R- and S-oxybutynin are similar in shape; Figure 2 shows the profile for R-oxybutynin when all available data are normalized to an equivalent of 5 mg twice daily.
