Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.
The use of benzodiazepines, including chlordiazepoxide, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes. Before prescribing clidinium/chlordiazepoxide and throughout treatment, assess each patient's risk for abuse, misuse, and addiction.
The continued use of benzodiazepines, including clidinium/chlordiazepoxide, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Abrupt discontinuation or rapid dosage reduction of clidinium/chlordiazepoxide after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue clidinium/chlordiazepoxide or reduce the dosage.
Dosage guidance:
Safety: Reduce dose or avoid use in patients receiving opioids or with significant chronic disease (eg, respiratory compromise) (Currow 2020; manufacturer's labeling). Avoid use in patients with a history of substance use, misuse of medications, or depression (Craske 2022).
Emotional and somatic factors in GI disorders:
Note: Use should be limited to short-term (eg, 2 to 4 weeks) reduction of situational anxiety that may be contributing to GI symptoms (Puasripun 2020; Soares 2014). Use with caution in patients with posttraumatic stress disorder; benzodiazepines may worsen symptoms (VA/DoD 2017).
Oral: 1 to 2 capsules 3 to 4 times daily.
Debilitated patients: Initial dose should not exceed 2 capsules per day, to be increased gradually as needed and tolerated.
Discontinuation of therapy: Unless safety concerns require a more rapid withdrawal, gradually taper to detect reemerging symptoms and minimize rebound and withdrawal symptoms (Lader 2011; VA/DoD 2021).
Low or moderate dose, no concerns for benzodiazepine use disorder : Taper total daily dose by 20% to 25% every week based on response and tolerability (taper increments will be limited by available dosage forms) (Craske 2022; VA/DoD 2021).
Extended or high-dose therapy, or suspected benzodiazepine use disorder: Taper total daily dose by ~25% every 1 to 2 weeks based on response, tolerability, and individual patient factors (taper increments will be limited by available dosage forms) (Park 2022; VA/DoD 2021). Reduce dose more rapidly in the beginning, and slow the dose reduction as the taper progresses because earlier stages of withdrawal are easier to tolerate (Lader 2011; VA/DoD 2021). The optimal duration and taper increment will vary; up to 6 months may be necessary for some patients on higher doses, and a taper rate of 50% every week may be tolerated in some patients (Park 2022; VA/DoD 2021).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustments provided in the manufacturer’s labeling; use with caution.

Canadian labeling: Additional contraindications (not in US labeling): Cardiovascular instability; hepatic impairment; hiatal hernia with reflux esophagitis; history of drug abuse or dependence; intestinal atony of the elderly or debilitated; GI obstruction; myasthenia gravis; predisposition to glaucoma; ulcerative colitis; urinary retention; severe respiratory insufficiency; psychotic disorders.
Concerns related to adverse effects:
• Anterograde amnesia: Benzodiazepines have been associated with anterograde amnesia (Nelson 1999).
• Anticholinergic effects: May cause anticholinergic effects (constipation, xerostomia, blurred vision, urinary retention).
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery, driving).
• Paradoxical reactions: Paradoxical reactions, including hyperactive or aggressive behavior, have been reported with benzodiazepines; risk may be increased in adolescent/pediatric patients, geriatric patients, or patients with a history of alcohol use disorder or psychiatric/personality disorders (Mancuso 2004).
• Sleep-related activities: Hazardous sleep-related activities such as sleep-driving, cooking and eating food, and making phone calls while asleep have been noted with benzodiazepines (Dolder 2008).
• Temperature regulation: Impaired core body temperature regulation may occur; caution with strenuous exercise, heat exposure, dehydration, and concomitant medication possessing anticholinergic effects (Kwok 2005; Martinez 2002).
Disease-related concerns:
• Depression: Avoid use in patients with depression because of concerns about worsening mood symptoms, particularly if suicidal risk may be present, except for acute or emergency situations (eg, acute agitation, status epilepticus) (Craske 2022).
• Hepatic impairment: Use with caution in patients with hepatic impairment.
• Renal impairment: Use with caution in patients with renal impairment.
• Respiratory disease: Reduce dose or avoid use in patients with respiratory disease, including chronic obstructive pulmonary disease or sleep apnea. Benzodiazepines may cause significant respiratory depression.
Concurrent drug therapy issues:
• Benzodiazepines and opioids: [US Boxed Warning]: The concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.
Special populations:
• Debilitated patients: Use with caution and at the smallest effective dose in debilitated patients.
• Older adult patients: Older adult patients may be at an increased risk of death with use; risk has been found highest within the first 4 months of use in older adult dementia patients (Jennum 2015; Saarelainen 2018).
• Fall risk: Use with extreme caution in patients who are at risk of falls; benzodiazepines have been associated with falls and traumatic injury (Nelson 1999).
Other warnings/precautions:
• Abuse, misuse, and substance use disorder: Counsel patients at increased risk on proper use and monitoring for signs and symptoms of abuse, misuse, and substance use disorder. Institute early treatment or refer patients in whom substance use disorder is suspected. Limit dosages and durations to the minimum required.
• Appropriate use: Does not have analgesic, antidepressant, or antipsychotic properties.
• Dependence and withdrawal reactions: Some patients may develop a protracted withdrawal syndrome lasting >12 months; may be difficult to differentiate withdrawal symptoms from reemergence or continuation of symptoms for which benzodiazepines were prescribed. Flumazenil may cause withdrawal in patients receiving long-term benzodiazepine therapy.

Beers Criteria: Chlordiazepoxide-clidinium is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older due to its highly anticholinergic properties and uncertain effectiveness as an antispasmodic. Chlordiazepoxide is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older due to risk of abuse, misuse, physical dependence, and addiction. In addition, older adults have increased risk of impaired cognition, delirium, falls, fractures, and motor vehicle accidents with benzodiazepine use, and slower metabolism of long-acting benzodiazepines (eg, chlordiazepoxide). However, benzodiazepines may be appropriate in the elderly when used for seizure disorders, rapid eye movement sleep behavior disorder, benzodiazepine or ethanol withdrawal, severe generalized anxiety disorder, or periprocedural anesthesia (Beers Criteria [AGS 2023]).
