How does this medication work? What will it do for me?
Chlordiazepoxide belongs to the class of medications called benzodiazepines. Chlordiazepoxide is used for the short-term relief of the symptoms of excessive anxiety and tension experienced with anxiety disorders. It may also be used to control symptoms, such as agitation, caused by alcohol withdrawal. It works by slowing down the speed at which the nerves in the brain (i.e., the central nervous system) send messages through the body.

HEALTH CANADA ADVISORY
October 30, 2020
Health Canada has issued new restrictions concerning the use of benzodiazepines and benzodiazepine-like prescription drugs. To read the full Health Canada Advisory, visit Health Canada’s web site at www.hc-sc.gc.ca.
Dependence/withdrawal: Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with benzodiazepines such as chlordiazepoxide. Severe withdrawal symptoms may occur if the dose is significantly reduced or suddenly discontinued. These symptoms include seizures, irritability, nervousness, sleep problems, agitation, tremors, diarrhea, abdominal cramps, vomiting, memory impairment, headache, muscle pain, extreme anxiety, tension, restlessness, and confusion. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms.
Drowsiness/reduced alertness: Because chlordiazepoxide causes drowsiness and sedation, do not engage in activities requiring mental alertness, judgment, and physical coordination (such as driving or operating machinery) while taking it. This is particularly true when first starting the medication and until you have established that chlordiazepoxide does not affect you in this way. Avoid alcohol because it can increase the drowsy effect of the medication.
Medical conditions: Chlordiazepoxide is not recommended for people with depression or psychosis. You should not take chlordiazepoxide if you are addicted to alcohol or other medications except in rare situations under medical supervision.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication may pass into breast milk. If you are a breast-feeding mother and are taking chlordiazepoxide, it may affect your baby. This medication is not recommended for breast-feeding women.
Seniors: Seniors may be at increased risk for the drowsiness and impaired coordination effects of this medication. You should use extra caution, for example, when getting up during the night.
What other drugs could interact with this medication?
There may be an interaction between chlordiazepoxide and any of the following:

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.
