Chlordiazepoxide - oral
Taking chlordiazepoxide with opioid medications (such as codeine, hydrocodone) may increase your risk of 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. 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.
Chlordiazepoxide is used to treat anxiety and acute alcohol withdrawal. It is also used to relieve fear and anxiety before surgery. This medication belongs to a class of drugs called benzodiazepines which act on the brain and nerves (central nervous system) to produce a calming effect. It works by enhancing the effects of a certain natural chemical in the body (GABA).
Read the Medication Guide provided by your pharmacist before you start taking chlordiazepoxide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
