Chlordiazepoxide HCl

Warning

Chlordiazepoxide has a risk for abuse and addiction, which can lead to overdose and death. Taking this medication with alcohol or other drugs that can cause drowsiness or breathing problems (especially opioid medications such as codeine, hydrocodone) may cause very serious side effects, including death. To lower your risk, your doctor should have you take the smallest dose of chlordiazepoxide that works, and take it for the shortest possible time. Be sure you know how to take chlordiazepoxide and what other drugs you should avoid taking with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.

Suddenly stopping this medication may cause serious (possibly fatal) withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as headaches, trouble sleeping, restlessness, hallucinations/confusion, depression, nausea, or seizures. Withdrawal symptoms may sometimes last weeks to months.

Precautions

Before taking this medication, tell your doctor or pharmacist if you are allergic to it; or to other benzodiazepines (such as diazepam, lorazepam); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease, kidney disease, lung/breathing problems (such as COPD, sleep apnea), blood disorder (porphyria), drug or alcohol abuse.

This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

Older adults may be more sensitive to the side effects of this drug, especially drowsiness. Drowsiness can increase the risk of falling.

Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using chlordiazepoxide. Chlordiazepoxide may harm an unborn baby. Newborn babies of mothers who use this medication late in pregnancy may have symptoms such as slow/shallow breathing, nonstop crying, shaking, or trouble feeding. If you become pregnant, talk to your doctor right away about the risks and benefits of this medication.

Based on information from related drugs, this drug may pass into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.
