How does this medicine work?[edit | edit source]

  • The hydrochloride salt form of chlordiazepoxide, a long-acting benzodiazepine with anxiolytic, sedative and hypnotic activity.
  • Chlordiazepoxide hydrochloride exerts its effect by binding to the benzodiazepine site at the gamma-aminobutyric acid (GABA) receptor-chloride ionophore complex in the central nervous system(CNS).
  • This leads to an increase in the opening of chloride channels, membrane hyperpolarization, and increases the inhibitory effect of GABA on the CNS.

  • 5 mg, 2 to 4 times daily (may be increased in some pediatric patients to 10 mg, 2 to 3 times daily).
  • Since clinical experience in pediatric patients under 6 years of age is limited, the use of the drug in this age group is not recommended.

What special precautions should I follow?[edit | edit source]

  • Chlordiazepoxide HCl may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a vehicle or operating machinery.
  • It may impair mental alertness in children.
  • The concomitant use of alcohol or other central nervous system depressants may have an additive effect.
  • Older adults should not usually take chlordiazepoxide because it is not as safe or effective as other medication(s) that can be used to treat the same condition.
  • In general, the concomitant administration of chlordiazepoxide HCl and other psychotropic agents is not recommended.
  • Paradoxical reactions, e.g., excitement, stimulation and acute rage, have been reported in psychiatric patients and in hyperactive aggressive pediatric patients, and should be watched for during chlordiazepoxide HCl therapy.
  • chlordiazepoxide with exacerbation of porphyria, caution should be exercised in prescribing chlordiazepoxide to patients suffering from this disease.
  • Withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (convulsions, tremor, abdominal and muscle cramps, vomiting and sweating), have occurred following abrupt discontinuance of chlordiazepoxide. Abrupt discontinuation should generally be avoided and a gradual dosage tapering schedule followed.
  • To assure the safe and effective use of benzodiazepines, patients should be informed that, since benzodiazepines may produce psychological and physical dependence, it is advisable that they consult with their physician before either increasing the dose or abruptly discontinuing this drug.
  • As with other benzodiazepines, chlordiazepoxide therapy is not associated with serum aminotransferase or alkaline phosphatase elevations, and clinically apparent liver injury from chlordiazepoxide has been reported, but is very rare.

What to do in case of emergency/overdose?[edit | edit source]

Symptoms of overdose may include:

Management of overdosage:

  • In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.
  • Overdose related information is also available online at poisonhelp.org/help.
  • In the event that the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services. In the United States, call 911.
  • Respiration, pulse and blood pressure should be monitored, as in all cases of drug overdosage, although, in general, these effects have been minimal following chlordiazepoxide HCl overdosage.
  • General supportive measures should be employed, along with immediate gastric lavage.
  • Intravenous fluids should be administered and an adequate airway maintained.
  • Hypotension may be combated by the use of norepinephrine or metaraminol.
  • Dialysis is of limited value.
  • There have been occasional reports of excitation in patients following chlordiazepoxide HCl overdosage; if this occurs barbiturates should not be used.
  • As with the management of intentional overdosage with any drug, it should be borne in mind that multiple agents may have been ingested.
  • Flumazenil, a specific benzodiazepine-receptor antagonist, is indicated for the complete or partial reversal of the sedative effects of benzodiazepines and may be used in situations when an overdose with a benzodiazepine is known or suspected.
  • The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long term benzodiazepine users and in cyclic antidepressant overdose.

Can this medicine be used in pregnancy?[edit | edit source]

  • An increased risk of congenital malformations associated with the use of minor tranquilizers (chlordiazepoxide, diazepam and meprobamate) during the first trimester of pregnancy has been suggested.
  • Patients should be advised that if they become pregnant during therapy or intend to become pregnant they should communicate with their physicians about the desirability of discontinuing the drug.

Can this medicine be used in children?[edit | edit source]

  • Because of the varied response of pediatric patients to CNS-acting drugs, therapy should be initiated with the lowest dose and increased as required.
  • Since clinical experience in pediatric patients under 6 years of age is limited, the use of the drug in this age group is not recommended.
