Warnings
Black Box Warnings
Concomitant use of benzodiazepines and opioids may result in profound respiratory depression, coma, and death; administer concomitantly when there are no alternative options; limit dosages and durations to minimum required; monitor for signs and symptoms of respiratory depression and sedation
Addiction, abuse, and misuse
- On September 2020, FDA addressed serious risks of benzodiazepine addiction, abuse, and misuse, which can lead to overdose and death
- Physical dependence can occur when taken steadily for several days to weeks, even as prescribed
- Stopping abruptly or reducing dosage too quickly can result in withdrawal reactions, including seizures, which can be life-threatening
- 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 and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction
- Assess each patient’s risk prior to prescribing and monitor regularly for the development of these conditions
- Risks of dependence and withdrawal increase with longer treatment duration and higher daily dose; although injection is indicated only for intermittent use, if used more frequently than recommended, abrupt discontinuation or rapid dosage reduction may precipitate acute withdrawal reactions, including seizures, which can be life-threatening; use gradual taper when discontinuing therapy to reduce withdrawal reactions risk
Contraindications
Hypersensitivity
Glaucoma
Prostatic hypertrophy
Benign bladder neck obstruction
Severe respiratory depression
Cautions
Decrease dose in debilitated or elderly patients
Concomitant administration with other psychotropic agents not recommended; if such combination seems indicated, give careful consideration to pharmacology of agents to be employed, particularly when known potentiating compounds such as MAO inhibitors and phenothiazines are to be used; usual precautions in treating patients with impaired renal or hepatic function should be observed
Paradoxical reactions to chlordiazepoxide have occurred (eg, excitement, stimulation, acute rage)
Anterograde amnesia reported with benzodiazepine use
May cause anticholinergic effects
May cause CNS depression, which may impair ability to perform hazardous tasks, including operating heavy machinery, driving
Although clinical studies have not established a cause and effect relationship, variable effects on blood coagulation have been reported very rarely in patients receiving oral anticoagulants and chlordiazepoxide hydrochloride
Use caution in hot weather; may cause heat prostration
Use of drug, particularly in patients at elevated risk of abuse, necessitates counseling about risks and proper use of drug along with monitoring for signs and symptoms of abuse, misuse, and addiction; do not exceed recommended dosing frequency
Avoid or minimize concomitant use of CNS depressants and other substances associated with abuse, misuse, and addiction (eg, opioid analgesics, stimulants); advise patients on proper disposal of unused drug; if a substance use disorder is suspected, evaluate patient and institute (or refer them for) early treatment, as appropriate
For patients using treated more frequently than recommended, to reduce risk of withdrawal reactions, use a gradual taper to discontinue therapy (a patient-specific plan should be used to taper the dose)
Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages, and those who have had longer durations of use
In some cases, benzodiazepine users have developed a protracted withdrawal syndrome with withdrawal symptoms lasting weeks to more than 12 months
Usual precautions are indicated when chlordiazepoxide hydrochloride is used to treat anxiety states where there is any evidence of impending depression; it should be borne in mind that suicidal tendencies may be present and protective measures may be necessary
Caution in patients with impaired gag reflex or respiratory disease
Concomitant use of opioid analgesics and benzodiazepines increases risk of drug-related mortality compared to use of opioids alone; if decision made to prescribe drug concomitantly with opioids, prescribe lowest effective dosages and minimum durations of concomitant use; follow patients closely for signs and symptoms of respiratory depression and sedation; advise both patients and caregivers about risks of respiratory depression and sedation when drug is used with opioids
Pregnancy & Lactation
Pregnancy

Available data from published observational studies of pregnant women exposed to benzodiazepines do not report a clear association with benzodiazepines and major birth defects

Over decades of use, there is an absence of published data on orally administered clidinium bromide in pregnant women, including an absence of any reports of a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes
Lactation
There are no data on presence of chlordiazepoxide in either human or animal milk, effects on breastfed infant, or on milk production; there are reports of sedation, poor feeding and poor weight gain in infants exposed to other benzodiazepines through breast milk
There are no data on presence of clidinium in either human or animal milk, effects on breastfed infant, or on milk production; as with other anticholinergic drugs, clidinium may cause suppression of lactation
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for this drug combination and any potential adverse effects on breastfed infant from
Infants exposed to this drug combination through breast milk should be monitored for sedation, poor feeding, and poor weight gain
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Chlordiazepoxide: Benzodiazepine; depresses all levels of CNS, including limbic and reticular formation, possibly by increasing gamma-aminobutyric acid (GABA) activity, a major inhibitory neurotransmitter
Clidinium: Anticholinergic agent; elicits antispasmodic and antisecretory effects on GI tract
Pharmacokinetics
Half-Life: 6-24 h (chlordiazepoxide)
Metabolites: Metabolized in liver to active metabolites; demoxepam, desmethylchlordiazepoxide, desmethyldiazepam, oxazepam
Excretion: Urine
