⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Risk of Urinary Retention: COBENFY can cause urinary retention. Geriatric patients and patients with bladder outlet obstruction and incomplete bladder emptying are at increased risk. Monitor patients for symptoms of acute urinary retention.
( 5.1 ) • Risk of Use in Patients with Hepatic Impairment: COBENFY is contraindicated in patients with moderate to severe hepatic impairment and is not recommended in patients with mild hepatic impairment. ( 5.2 ) • Risk of Use in Patients with Biliary Disease: Assess liver enzymes and bilirubin prior to initiating COBENFY and as clinically indicated. Discontinue COBENFY in the presence of signs or symptoms of substantial liver injury.
( 5.3 ) • Decreased Gastrointestinal Motility: COBENFY may decrease gastrointestinal motility. Use with caution in patients with gastrointestinal obstructive disorders because of the risk of gastric retention. ( 5.4 ) • Risk of Angioedema: Angioedema of the face, lips, tongue and/or larynx has been reported with COBENFY.
( 5.5 ) • Risk of Use in Patients with Narrow-angle Glaucoma: Use COBENFY only if the potential benefits outweigh the risks and with careful monitoring. ( 5.6 ) • Increases in Heart Rate: COBENFY may increase heart rate. Assess heart rate at baseline and as clinically indicated during treatment with COBENFY.
( 5.7 ) • Anticholinergic Adverse Reactions in Patients with Renal Impairment: COBENFY is not recommended for use in patients with moderate and severe renal impairment. Anticholinergic adverse reactions are expected to be greater in these patients. ( 5.8 ) • Central Nervous System Effects: COBENFY may be associated with CNS effects.
Advise patients not drive or operate heavy machinery until they know how COBENFY affects them. ( 5.9 )
5.1Risk of Urinary Retention COBENFY can cause urinary retention [see Adverse Reactions (6.1 )] . Geriatric patients and patients with clinically significant bladder outlet obstruction and incomplete bladder emptying (e.g., patients with benign prostatic hyperplasia (BPH), diabetic cystopathy) may be at increased risk of urinary retention [see Use in Specific Populations (8.5) ] . COBENFY is contraindicated in patients with pre-existing urinary retention [see Contraindications (4) ] and is not recommended in patients with moderate or severe renal impairment [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ] .
In patients taking COBENFY, monitor for symptoms of urinary retention, including urinary hesitancy, weak stream, incomplete bladder emptying, and dysuria. Instruct patients to be aware of the risk and promptly report symptoms of urinary retention to their healthcare provider. Urinary retention is a known risk factor for urinary tract infections.
In patients with symptoms of urinary retention, consider reducing the dose of COBENFY, discontinuing COBENFY, or referring patients for urologic evaluation as clinically indicated.
5.2Risk of Use in Patients with Hepatic Impairment Patients with hepatic impairment have higher systemic exposures of xanomeline, a component of COBENFY, compared to patients with normal hepatic function, which may result in increased incidence of COBENFY-related adverse reactions [see Clinical Pharmacology (12.3) ] . COBENFY is contraindicated in patients with moderate or severe hepatic impairment [see Contraindications (4) ] . COBENFY is not recommended in patients with mild hepatic impairment [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3) ] .

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Risk of Urinary Retention [see Warnings and Precautions (5.1) ] • Risk of Use in Patients with Hepatic Impairment [see Warnings and Precautions (5.2) ] • Risk of Use in Patients with Biliary Disease [see Warnings and Precautions (5.3) ] • Decreased Gastrointestinal Motility [see Warnings and Precautions (5.4) ] • Risk of Angioedema [see Warnings and Precautions (5.5) ] • Risk of Use in Patients with Narrow-angle Glaucoma [see Warnings and Precautions (5.6) ] • Increases in Heart Rate [see Warnings and Precautions (5.7) ] • Anticholinergic Adverse Reactions in Patients with Renal Impairment [see Warnings and Precautions (5.8) ] • Central Nervous System Effects [see Warnings and Precautions (5.9) ] Most common adverse reactions (incidence ≥ 5% and at least twice placebo) were nausea, dyspepsia, constipation, vomiting, hypertension, abdominal pain, diarrhea, tachycardia, dizziness, and gastrointestinal reflux disease.
( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bristol-Myers Squibb at 1-800-721-5072 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. COBENFY was evaluated for safety in a total of 1,594 subjects exposed to one or more doses, including 1,135 adult patients with schizophrenia and 389 healthy subjects. A total of 347 COBENFY-treated patients had at least 6 months of exposure and 150 patients had at least 1 year of exposure (defined as ≥ 50 weeks) from open-label studies.
The adverse reaction findings are based on two pooled 5-week, placebo-controlled, flexible-dose studies in 504 adult patients with schizophrenia in which COBENFY or placebo was started at an initial dose of 50 mg/20 mg twice daily for the first 2 days followed by 100 mg/20 mg twice daily for the remainder of Week 1 (Days 3 to 7). On Day 8, dosing was titrated to 125 mg/30 mg twice daily unless the patient could not tolerate it. All patients had the option to return to 100 mg/20 mg twice daily for the remainder of the treatment period [see Clinical Studies (14) ] .
In the 5-week placebo-controlled studies, 6% of patients treated with COBENFY and 4% of placebo-treated patients discontinued participation due to adverse reactions. Adverse reactions that led to study discontinuation in ≥1% of patients treated with COBENFY include nausea (2%) and vomiting (1%). The most common adverse reactions (≥5% and at least twice placebo) were nausea, dyspepsia, constipation, vomiting, hypertension, abdominal pain, diarrhea, tachycardia, dizziness, and gastroesophageal reflux disease.
Adverse reactions reported with COBENFY at an incidence of at least 2% in patients exposed to COBENFY and greater than the rate of placebo are shown in Table 1. Table 1: Adverse Reactions Reported in ≥2% of COBENFY-Treated Patients and Greater than Rate of Placebo in Two 5-week Schizophrenia Trials a Dyspepsia includes dyspepsia, esophageal discomfort b Hypertension includes hypertension, blood pressure increased, labile hypertension, orthostatic hypertension c Abdominal Pain includes abdominal discomfort, abdominal pain upper, abdominal pain, abdominal pain lower, abdominal tenderness d Tachycardia includes tachycardia, heart rate increased, sinus tachycardia e Cough: includes cough, productive cough f EPS (non-akathisia) includes dyskinesia, drooling, dystonia, extrapyramidal disorder, muscle contraction involuntary, muscle spasms COBENFY (N=251) Placebo (N=253) Nausea 19% 4% Dyspepsia a 18% 5% Constipation 17% 7% Vomiting 15% 1% Hypertension b 11% 2% Abdominal Pain c 8% 4% Diarrhea 6% 2% Tachycardia d 5% 2% Dizziness 5% 2% Gastroesophageal reflux disease 5% <1% Dry mouth…

7 DRUG INTERACTIONS • Drugs Eliminated by Active Tubular Secretion: Monitor for increased frequency and/or severity of adverse reactions related to COBENFY and to drugs eliminated by active tubular secretion. ( 7.1 ) • Strong CYP2D6 Inhibitors: Monitor for increased frequency and/or severity of COBENFY-related adverse reactions. ( 7.1 ) • Sensitive Substrates of CYP3A4 or P-glycoprotein: Monitor for increased frequency and/or severity of adverse reactions from these substrates.
( 7.1 ) • Antimuscarinic Drugs: Monitor for increased frequency or severity of anticholinergic adverse reactions. ( 7.2 )
7.1Clinically Significant Drug Interactions with COBENFY Table 2 displays clinically significant drug interactions with COBENFY. Table 2: Clinically Significant Drug Interactions with COBENFY Strong Inhibitors of CYP2D6 Clinical Implication: CYP2D6 contributes significantly to the metabolism of xanomeline, a component of COBENFY. Concomitant use of COBENFY with strong CYP2D6 inhibitors may increase plasma concentrations of xanomeline, which may increase the frequency and/or severity of adverse reactions from COBENFY [see Clinical Pharmacology (12.3)] .
Prevention or Management: Monitor patients for increased frequency and/or severity of adverse reactions related to COBENFY in patients taking COBENFY with strong inhibitors of CYP2D6. Drugs Eliminated by Active Tubular Secretion Clinical Implication: Concomitant use of COBENFY with drugs that are eliminated by active tubular secretion may increase plasma concentrations of trospium a component of COBENFY, and/or the concomitantly used drug due to competition for this elimination pathway, which may increase the frequency and/or severity of adverse reactions from COBENFY or the drug eliminated by active tubular secretion [see Clinical Pharmacology (12.3)] .
Prevention or Management: Monitor patients for increased frequency and/or severity of adverse reactions related to COBENFY and adverse reactions related to drugs eliminated by active tubular secretion in patients concomitantly receiving such drugs. Oral Drugs That Are Sensitive Substrates of CYP3A4 Clinical Implication: Xanomeline, a component of COBENFY, transiently inhibits CYP3A4 locally in the gut but not systemically. Concomitant use of COBENFY with oral drugs that are sensitive substrates of CYP3A4 may result in increased plasma concentrations of the oral drugs that are sensitive substrates of CYP3A4.
This may increase the frequency and/or severity of adverse reactions from such substrates [see Clinical Pharmacology (12.3)] . Prevention or Management: Monitor patients for increased frequency and/or severity of adverse reactions related to oral drugs that are sensitive substrates of CYP3A4 in patients taking COBENFY with such substrates. Oral Drugs That Are Substrates of P-glycoprotein Clinical Implication: Xanomeline, a component of COBENFY, transiently inhibits P-glycoprotein locally in the gut but not systemically.
Concomitant use of COBENFY with oral drugs that are substrates of P-glycoprotein may result in increased plasma concentrations of the oral drugs that are substrates of P-glycoprotein, which may increase the frequency and/or severity of adverse reactions from such substrates [see Clinical Pharmacology (12.3)] . Prevention or Management: Monitor patients for increased frequency and/or severity of adverse reactions related to oral drugs that are narrow therapeutic index substrates of P-glycoprotein in patients taking COBENFY with such substrates.
7.2Other Antimuscarinic Drugs Concomitant use of COBENFY with other antimuscarinic drugs that produce anticholinergic adverse reactions (e.g., dry mouth, constipation) may increase the frequency and/or severity of such effects. Monitor patients for increased frequency and/or severity of anticholinergic adverse reactions when COBENFY is used concomitantly with other antimuscarinic drugs.
7.3Effects on Absorption of Drugs COBENFY may potentially alter the absorption of some co…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS • Moderate or Severe Renal Impairment: Not recommended. ( 8.6 ) • Mild Hepatic Impairment: Not recommended. ( 8.7 )
8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors outcomes in women exposed to psychiatric medications, including COBENFY, during pregnancy. Healthcare providers are encouraged to advise patients to register by calling 1-866-961-2388 or visiting online at https://womensmentalhealth.org/research/pregnancyregistry/atypicalantipsychotic/ . Risk Summary There are no available data on COBENFY use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes.
There are risks to the mother associated with untreated schizophrenia ( see Clinical Considerations ). In animal reproduction studies, oral administration of xanomeline alone or in combination with trospium chloride during the period of organogenesis or during pregnancy and lactation caused maternal toxicities of adverse clinical signs, decreased body weight, weight gain and food consumption, and/or maternal death. At these maternally toxic doses, embryofetal and developmental toxicities included decreased fetal and neonatal weight, stillborn pups, and/or neonatal deaths.
The no observed adverse effect level (NOAEL) of xanomeline or xanomeline/trospium chloride combination for maternal, embryofetal, and/or developmental toxicity is equal to or higher than the xanomeline and trospium chloride dose at the maximum recommended human dose (MRHD) of 250/60 mg xanomeline/trospium chloride, based on mg/m 2 body surface area (BSA) (see Data). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of major birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryofetal risk There is a risk to the pregnant patient from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia is associated with adverse perinatal outcomes, including preterm birth.
It is not known if this is a direct result of the illness or other comorbid factors. Data Animal Data Pregnant rats were orally treated during the period of organogenesis with 150 mg/kg/day xanomeline alone, 100 mg/kg/day trospium chloride alone, or xanomeline/trospium chloride combination at 30/25, 75/50, and 150/100 mg/kg/day, respectively. Xanomeline alone and the high dose combination caused maternal toxicities of decreased body weight, weight gain, and food consumption.
At these maternally toxic doses, fetal weights were decreased. The NOAEL for maternal and embryofetal toxicity is 75/50 mg/kg/day for the combination, which is approximately 3 and 8 times the xanomeline and trospium chloride dose, respectively, at the MRHD of 250/60 mg xanomeline/trospium chloride, based on BSA. No fetal malformation was observed.
Trospium chloride alone did not cause maternal or embryofetal toxicity. Pregnant rabbits were orally treated during the period of organogenesis with120 mg/kg/day xanomeline alone, 80 mg/kg/day trospium chloride alone, or xanomeline/trospium chloride combination at 30/20, 60/40, and 120/80 mg/kg/day, respectively. Xanomeline alone and the high dose combination caused maternal toxicities of decreased body weight, weight gain, and food consumption, and/or early abortion.
At these maternally toxic doses, decreased fetal weight and decreased fetal viability (increased resorption and post-implantation loss) were observed. The NOAEL for maternal and embryofetal toxicity is 60/40 mg/kg/day for the xanomeline/trospium chloride combination, which is 5 and 13 times the xanomeline and trospium chloride dose, respectively at…

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors outcomes in women exposed to psychiatric medications, including COBENFY, during pregnancy. Healthcare providers are encouraged to advise patients to register by calling 1-866-961-2388 or visiting online at https://womensmentalhealth.org/research/pregnancyregistry/atypicalantipsychotic/ . Risk Summary There are no available data on COBENFY use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes.
There are risks to the mother associated with untreated schizophrenia ( see Clinical Considerations ). In animal reproduction studies, oral administration of xanomeline alone or in combination with trospium chloride during the period of organogenesis or during pregnancy and lactation caused maternal toxicities of adverse clinical signs, decreased body weight, weight gain and food consumption, and/or maternal death. At these maternally toxic doses, embryofetal and developmental toxicities included decreased fetal and neonatal weight, stillborn pups, and/or neonatal deaths.
The no observed adverse effect level (NOAEL) of xanomeline or xanomeline/trospium chloride combination for maternal, embryofetal, and/or developmental toxicity is equal to or higher than the xanomeline and trospium chloride dose at the maximum recommended human dose (MRHD) of 250/60 mg xanomeline/trospium chloride, based on mg/m 2 body surface area (BSA) (see Data). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of major birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryofetal risk There is a risk to the pregnant patient from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia is associated with adverse perinatal outcomes, including preterm birth.
It is not known if this is a direct result of the illness or other comorbid factors. Data Animal Data Pregnant rats were orally treated during the period of organogenesis with 150 mg/kg/day xanomeline alone, 100 mg/kg/day trospium chloride alone, or xanomeline/trospium chloride combination at 30/25, 75/50, and 150/100 mg/kg/day, respectively. Xanomeline alone and the high dose combination caused maternal toxicities of decreased body weight, weight gain, and food consumption.
At these maternally toxic doses, fetal weights were decreased. The NOAEL for maternal and embryofetal toxicity is 75/50 mg/kg/day for the combination, which is approximately 3 and 8 times the xanomeline and trospium chloride dose, respectively, at the MRHD of 250/60 mg xanomeline/trospium chloride, based on BSA. No fetal malformation was observed.
Trospium chloride alone did not cause maternal or embryofetal toxicity. Pregnant rabbits were orally treated during the period of organogenesis with120 mg/kg/day xanomeline alone, 80 mg/kg/day trospium chloride alone, or xanomeline/trospium chloride combination at 30/20, 60/40, and 120/80 mg/kg/day, respectively. Xanomeline alone and the high dose combination caused maternal toxicities of decreased body weight, weight gain, and food consumption, and/or early abortion.
At these maternally toxic doses, decreased fetal weight and decreased fetal viability (increased resorption and post-implantation loss) were observed. The NOAEL for maternal and embryofetal toxicity is 60/40 mg/kg/day for the xanomeline/trospium chloride combination, which is 5 and 13 times the xanomeline and trospium chloride dose, respectively at the MRHD, based on BSA.

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of COBENFY in pediatric patients have not been established.
🧓 Geriatric Use ▾
8.5Geriatric Use Controlled clinical studies of COBENFY did not include patients older than 65 years of age to determine whether they respond differently from younger adult patients. Because COBENFY can increase the risk of urinary retention in geriatric patients, including older males with bladder outlet obstruction due to benign prostatic hyperplasia (BPH), a slower titration and lower maximum dosage is recommended in geriatric patients [see Dosage and Administration (2.3) and Warnings and Precautions (5.1) ] .
🆘 Overdosage ▾
10 OVERDOSAGE Overdose of COBENFY may produce cholinergic, anticholinergic or a combination of cholinergic and anticholinergic signs and symptoms: • Cholinergic Signs and Symptoms: seizures, vomiting, diarrhea, abdominal pain, hyperhidrosis, salivary hypersecretion, and hypotension possibly preceded by hypertension. • Anticholinergic Signs and Symptoms (geriatric patients may be more susceptible): delirium, agitation, garbled speech, dizziness, hypertension, tachycardia, dry mouth and eyes, ileus, blurred vision, and urinary retention.
Consider calling the Poison Help Line 1-800-222-1222 or a medical toxicologist for specific treatment recommendations.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism of action of xanomeline in the treatment of schizophrenia is unclear; however, its efficacy is thought to be due to its agonist activity at M1 and M4 muscarinic acetylcholine receptors in the central nervous system. Trospium chloride is a muscarinic antagonist. Trospium chloride antagonizes the muscarinic receptors primarily in the peripheral tissues.
12.2Pharmacodynamics Xanomeline binds to muscarinic receptors M1 to M5 with comparable affinity (Ki=10, 12, 17, 7, and 22 nM for the M1, M2, M3, M4, and M5 receptors, respectively) and exhibits higher agonist activity at the M1 and M4 receptors. Trospium chloride antagonizes the muscarinic receptors primarily in peripheral tissues. Cardiac Electrophysiology At the maximum recommended dosage of 125 mg/30 mg twice daily, COBENFY does not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics Following COBENFY administration, xanomeline area under the plasma concentration-time curve during a 12-hour dosing interval (AUC 0-12 ) at steady state and maximum concentration (C max ) increased 50% when the COBENFY dose increased from 100 mg/20 mg twice daily to 125 mg/30 mg twice daily. Trospium exposures increase dose-proportionally over the COBENFY dosage range of 100 mg/20 mg twice daily to 125 mg/30 mg twice daily. Pharmacokinetic properties of COBENFY are provided in Table 3.

The exposures (AUC 0-12h and C max ) of xanomeline at steady state were not different between subjects 65 years and older and subjects younger than 65 years old [see Dosage and Administration (2.3) and Use in Specific Populations (8.5) ] . Male and Female Patients Plasma concentrations of xanomeline and trospium are similar between females and males. Racial or Ethnic Groups Most subjects in clinical studies were Black.
Xanomeline and trospium exposure did not differ between Black and non-Black subjects. Studies have included too few subjects of Asian descent to evaluate comparisons. Patients with Renal Impairment The effect of renal impairment on xanomeline and trospium exposure was assessed in a dedicated study that enrolled healthy subjects and subjects with mild, moderate, or severe renal impairment.
Estimated glomerular filtration rate (eGFR) was determined by the MDRD equation.…

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Risk of Urinary Retention Inform patients that COBENFY may cause urinary retention and that the risk of urinary retention is greater in some patients, including geriatric patients and those with bladder outlet obstruction (e.g., due to BPH) and patients with other causes of reduced bladder emptying (e.g., diabetic cystopathy). Urinary retention may occur at any time during treatment with COBENFY and is more likely when taking higher doses.
Advise patients to monitor for symptoms of urinary retention, such as urinary hesitancy, weak urinary stream, incomplete bladder emptying and pain with urination, and to promptly report these symptoms to their healthcare provider. Inform patients that urinary retention may increase the risk of urinary tract infection. Advise patients to seek immediate medical attention if they are unable to urinate [see Warnings and Precautions (5.1) ] .
Risk of Use in Patients with Hepatic Impairment Instruct patients to report signs of hepatic impairment (e.g., skin and eyes that appear yellowish, abdominal pain and swelling, itchy skin, dark urine color) and symptoms of hepatic injury (e.g., biliary spasm, pancreatitis, and cholangitis) to their healthcare provider [see Warnings and Precautions (5.2) ] . Risk of Use in Patients with Biliary Disease Inform patients that COBENFY can increase liver enzymes and about the need for specific monitoring, including liver enzymes and bilirubin levels.
Inform patients to report symptoms such as dyspepsia, nausea, vomiting, or upper abdominal pain to their healthcare provider [see Warnings and Precautions (5.3) ] . Decreased Gastrointestinal Motility Inform patients that COBENFY can delay or slow emptying of food in their stomach. Advise patients to inform their healthcare provider about the presence of or symptoms of gastrointestinal obstructive disorders and conditions such as ulcerative colitis, intestinal atony, and myasthenia gravis [see Warnings and Precautions (5.4) ] .
Risk of Angioedema Advise patients that hypersensitivity reactions to COBENFY could and occur and result in life-threatening airway obstruction. Instruct patients to seek medical attention if they experience edema of the tongue, edema of the laryngopharynx, or difficulty breathing occurs, discontinue COBENFY, and seek immediate medical attention [see Warnings and Precautions (5.5) ] . Risk of Use in Patients with Narrow-angle Glaucoma Inform patients pupillary dilation may occur with COBENFY use and in susceptible individuals, can lead to an episode of angle closure glaucoma [see Warnings and Precautions (5.6) ] .
Increases in Heart Rate Inform patients that COBENFY can increase heart rate [see Warnings and Precautions (5.7) ] . Anticholinergic Adverse Reactions in Patients with Renal Impairment Inform patients that COBENFY is associated with anticholinergic adverse reactions such as dry mouth, constipation, dyspepsia, urinary tract infection, and urinary retention and the effects are expected to be greater in patients with renal impairment [see Warnings and Precautions (5.8) ] . Central Nervous System Effects Advise patients that COBENFY is associated with central nervous system effects such as dizziness, confusion, hallucinations, and somnolence.
Caution patients about performing activities requiring mental alertness, such as operating hazardous machinery or operating a motor vehicle, until they are reasonably certain that COBENFY therapy does not adversely affect their ability to engage in such activities [see Warnings and Precautions (5.9) ] .
