Side Effects of Librax

Librax is a drug that is used to relax the muscles in the intestines and the bladder. It's one of a type of drugs called benzodiazepines. Librax is a combination of two drugs, chlordiazepoxide and clidinium. It's frequently used to treat irritable bowel syndrome (IBS).

Components of Librax

Chlordiazepoxide, which is one part of Librax, is in a class of drugs called benzodiazepines. Benzodiazepines, sometimes called benzos, may be prescribed to treat tension or anxiety. The clidinium component is an anticholinergic. It relaxes the muscles in the gut and the bladder and prevents spasms. In addition, clidiniuman lowers the production of stomach acid.

Important Things to Know

Librax may have a sedative effect, which means that it may make people tired or drowsy. For that reason, it's often recommended that people not drive when taking it as well as avoid alcoholic beverages. This, of course, limits its usefulness as a medication for IBS or other chronic conditions.

People with glaucoma, a bladder obstruction, or an enlarged prostate gland shouldn't use Librax. Because of the benzo part of Librax, people who have had difficulty with drug addiction in the past might not be able to take this drug. Librax also shouldn't be taken along with other medications that affect the central nervous system, such as antidepressants.

After taking Librax for a long time, some people might experience withdrawal symptoms when they stop taking it. For this reason, it's important to taper the use of Librax down slowly, rather than stopping it altogether.

Librax shouldn't be used by pregnant women in the first trimester because it has been associated with an increased risk of birth defects. Even after the first trimester, Librax isn't typically used in pregnant women. Women taking Librax should talk to their doctor if there is a possibility of becoming pregnant. Librax is also not typically recommended for women who are breastfeeding an infant.
