What is Librax?
Librax is a capsule containing a combination of chlordiazepoxide and clidinium. Chlordiazepoxide is in a group of drugs called benzodiazepines. Chlordiazepoxide affects chemicals in the brain that may become unbalanced and cause anxiety.
Clidinium reduces stomach acid and decreases intestinal spasms.
Librax is used to treat stomach ulcers, irritable bowel syndrome, and intestinal infections.
Librax may also be used for other purposes not listed.
Do not use Librax if you are allergic to chlordiazepoxide or clidinium, or to other benzodiazepines, such as alprazolam (Xanax), clorazepate (Tranxene), diazepam (Valium), lorazepam (Ativan), or oxazepam (Serax). Librax can cause birth defects in an unborn baby. Do not use this medicine if you are pregnant.
Before taking Librax, tell your doctor if you have any breathing problems, glaucoma, porphyria, kidney or liver disease, or a history of depression, suicidal thoughts, or addiction to drugs or alcohol.
Do not drink alcohol while taking Librax. This medication can increase the effects of alcohol. Librax can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert. This medication may be habit-forming and should be used only by the person it was prescribed for. Librax should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.
