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.

Important information

Librax can cause birth defects in an unborn baby. Do not use this medicine if you are pregnant.
