Dermatologic: Skin rash
Endocrine & metabolic: Change in libido, menstrual disease
Gastrointestinal: Constipation, nausea
Hematologic & oncologic: Agranulocytosis, bone marrow depression
Hepatic: Hepatic insufficiency, jaundice
Miscellaneous: Paradoxical reaction
Concerns related to adverse effects:
- Anterograde amnesia: Benzodiazepines have been associated with anterograde amnesia.
- CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
- Paradoxical reactions: Paradoxical reactions, including hyperactive or aggressive behavior, have been reported with benzodiazepines, particularly in adolescent/pediatric or psychiatric patients.
Disease-related concerns:
- Depression: Use caution in patients with depression, particularly if suicidal risk may be present.
- Drug abuse: Use with caution in patients with a history of drug abuse or acute alcoholism; potential for drug dependency exists. Tolerance, psychological and physical dependence may occur with prolonged use.
- Hepatic impairment: Use with caution in patients with hepatic impairment.
- Impaired gag reflex: Use with caution in patients with an impaired gag reflex.
- Porphyria: Use with caution in patients with porphyria.
- Renal impairment: Use with caution in patients with renal impairment.
- Respiratory disease: Use with caution in patients with respiratory disease.
Concurrent drug therapy issues:
- CNS depressants/psychoactive medications: Use with caution in patients receiving other CNS depressants or psychoactive medication; effects with other sedative drugs or ethanol may be potentiated.
Special populations:
- Debilitated patients: Use with caution in debilitated patients; active metabolites with extended half-lives may lead to delayed accumulation and adverse effects.
- Fall risk: Use with extreme caution in patients who are at risk of falls; benzodiazepines have been associated with falls and traumatic injury.
- Pediatric: Use with caution in children; active metabolites with extended half-lives may lead to delayed accumulation and adverse effects.
Other warnings/precautions:
- Appropriate use: Does not have analgesic, antidepressant, or antipsychotic properties. Duration of use longer than 4 months has not been studied.
- Tolerance: Chlordiazepoxide is a long half-life benzodiazepine. Duration of action after a single dose is determined by redistribution rather than metabolism. Tolerance does not develop to the anxiolytic effects (Vinkers, 2012). Chronic use of this agent may increase the perioperative benzodiazepine dose needed to achieve desired effect.
- Withdrawal: Rebound or withdrawal symptoms may occur following abrupt discontinuation or large decreases in dose. Use caution when reducing dose or withdrawing therapy; decrease slowly and monitor for withdrawal symptoms. Flumazenil may cause withdrawal in patients receiving long-term benzodiazepine therapy.

Adverse events were observed in some animal reproduction studies. Chlordiazepoxide crosses the human placenta and fetal serum concentrations are similar to those in the mother. Teratogenic effects have been observed with some benzodiazepines (including chlordiazepoxide); however, additional studies are needed. The incidence of premature birth and low birth weights may be increased following maternal use of benzodiazepines; hypoglycemia and respiratory problems in the neonate may occur following exposure late in pregnancy. Neonatal withdrawal symptoms may occur within days to weeks after birth and "floppy infant syndrome " � (which also includes withdrawal symptoms) has been reported with some benzodiazepines (Bergman, 1992; Iqbal, 2002; Wikner, 2007). .
Binds to stereospecific benzodiazepine receptors on the postsynaptic GABA neuron at several sites within the central nervous system, including the limbic system, reticular formation. Enhancement of the inhibitory effect of GABA on neuronal excitability results by increased neuronal membrane permeability to chloride ions. This shift in chloride ions results in hyperpolarization (a less excitable state) and stabilization. Benzodiazepine receptors and effects appear to be linked to the GABA-A receptors. Benzodiazepines do not bind to GABA-B receptors.

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience fatigue or headache. Have patient report immediately to prescriber signs of depression (suicidal ideation, anxiety, emotional instability, or illogical thinking), change in balance, confusion, severe loss of strength and energy, severe dizziness, passing out, vision changes, or jaundice (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
