Chlordiazepoxide and Clidinium (Oral)

Chlordiazepoxide and Clidinium, which is also known by its brand name Librax, is a blended oral medication that is used to treat some stomach and bowel disorders.


This medication is a combination of two medications: Chlordiazepoxide, which belongs to a class of benzodiazepines, and Clidinium, which belongs to a class of drugs known as antispasmodics. The combination works to relax muscles in the stomach and intestines, thus slowing the natural movements of the gut. This helps to relieve symptoms in various bowel and stomach disorders. This medication alone is not normally used to treat the conditions it is indicated for; normally, it will be given as an additive to further help relieve symptoms and aid in ongoing treatments. It might not be effective in all patients, so it is important to have communication with your doctor while you are taking this medication to make sure it is working for you.

This medication has been known to cause addiction. While it is not common, the chances of developing an addiction may increase if the patient has other substance abuse disorders. It is important to take the medication exactly as it is prescribed in order to lower the chances of developing an addiction. The medication can also have withdrawal effects, especially if used in higher doses than prescribed, more than prescribed, and for a long time.

Some of the side effects of withdrawal for this medication if the medication is stopped suddenly can include:

  • Shakiness

Dosage is based on the patient's age, medical history, the seriousness of the disease, and response to treatments. It is normal to start the patient off with a lower dose to reduce the risk of side effects and move the dosage up if needed. Normally the dosage will start at only one to two capsules per day and increase as the individual builds up a tolerance. It is normally about 5 mg of Chlordiazepoxide and 2.5 mg of Clidinium for the active ingredients, with the pill containing other inactive ingredients as well. The dosage should never be increased with doctor approval, as it could increase the risk of harmful side effects. The medication is normally intended to be used over a short-term period, and using it for long amounts of time may potentially lower its effectiveness.

The medication is normally taken three to four times a day before meals and before bedtime. When taken before meals it is normally taken 30 to 60 minutes prior to the meal. If a patient is on antacids as well as this medication, take the medication as you would normally and take the antacid after you have finished your meal so the two do not interfere with each other. Talk with your doctor about the specific times that the medication should be taken.

If you miss a dose, you should take the missed dose as soon as you remember it as long as it is not time for your next dose. If it is time for your next dose, do not take two doses to make up for the missed dose. Doing so can increase your potential for overdose and experiencing harmful side effects. If you miss a dose and it is time for your next dose, simply skip the missed dose and continue taking your medication as normal.
