Before taking this medicine
You should not use Librium if you are allergic to it.
To make sure Librium is safe for you, tell your doctor if:
you have porphyria (a genetic enzyme disorder that causes symptoms affecting the skin or nervous system);
you take a narcotic (opioid) medication.
The sedative effects of chlordiazepoxide may last longer in older adults. Accidental falls are common in elderly patients who take benzodiazepines. Use caution to avoid falling or accidental injury while you are taking Librium.
Do not use Librium if you are pregnant. This medicine can cause birth defects. Your baby could also become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant. Use effective birth control to prevent pregnancy while you are taking this medicine.
It is not known whether chlordiazepoxide passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
