CLIDINIUM/CHLORDIAZEPOXIDE - ORAL
COMMON BRAND NAME(S): Librax
WARNING: Taking chlordiazepoxide with opioid medications (such as codeine, hydrocodone) may increase your risk of very serious side effects, including death.

It is used along with other medications to help treat stomach/intestinal disorders (such as ulcers, irritable bowel syndrome, bowel infections). Clidinium helps to reduce the symptoms of stomach and intestinal cramping. It works by slowing the natural movements of the gut and by relaxing the muscles in the stomach and intestines. Clidinium belongs to a class of drugs known as anticholinergics/antispasmodics. Chlordiazepoxide helps to reduce anxiety. It acts on the brain and nerves to produce a calming effect. It belongs to a class of drugs known as benzodiazepines.
