Uses of This Medicine:

Benzodiazepines belong to the group of medicines called central nervous system (CNS) depressants (medicines that slow down the nervous system).

Some benzodiazepines are used to relieve anxiety. However, benzodiazepines should not be used to relieve nervousness or tension caused by the stress of everyday life.

Some benzodiazepines are used to treat insomnia (trouble in sleeping). However, if used regularly (for example, every day) for insomnia, they usually are not effective for more than a few weeks.

Many of the benzodiazepines are used in the treatment of other conditions, also. Diazepam is used to help relax muscles or relieve muscle spasm. Diazepam injection is used before some medical procedures to relieve anxiety and to reduce memory of the procedure. Chlordiazepoxide, clorazepate, diazepam, and oxazepam are used to treat the symptoms of alcohol withdrawal. Alprazolam and clonazepam are used in the treatment of panic disorder. Clobazam, clonazepam, clorazepate, diazepam, and lorazepam are used in the treatment of certain convulsive (seizure) disorders, such as epilepsy. The benzodiazepines may also be used for other conditions as determined by your doctor.

Benzodiazepines may be habit-forming (causing mental or physical dependence), especially when taken for a long time or in high doses.

These medicines are available only with your doctor's prescription.

Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, some of the benzodiazepines are used in certain patients with the following medical conditions:

  • Nausea and vomiting caused by cancer chemotherapy
  • Tension headache
  • Tremors

Before Using This Medicine:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children

Most of the side effects of these medicines are more likely to occur in children, especially the very young. These patients are usually more sensitive than adults to the effects of benzodiazepines.

It is possible that using clonazepam for long periods of time may cause unwanted effects on physical and mental growth in children. If such effects do occur, they may not be noticed until many years later. Before this medicine is given to children for long periods of time, you should discuss its use with your child's doctor.

Older adults

Most of the side effects of these medicines are more likely to occur in the elderly, who are usually more sensitive to the effects of benzodiazepines.

Taking benzodiazepines for trouble in sleeping may cause more daytime drowsiness in elderly patients than in younger adults. In addition, falls and related injuries are more likely to occur in elderly patients taking benzodiazepines.

Pregnancy

Chlordiazepoxide and diazepam have been reported to increase the chance of birth defects when used during the first 3 months of pregnancy. Although similar problems have not been reported with the other benzodiazepines, the chance always exists since all of the benzodiazepines are related.

Studies in animals have shown that clonazepam, lorazepam, and temazepam cause birth defects or other problems, including death of the animal fetus.

Too much use of a benzodiazepine during pregnancy may cause the baby to become dependent on the medicine. This may lead to withdrawal side effects after birth. Also, use of benzodiazepines during pregnancy, especially during the last weeks, may cause body temperature problems, breathing problems, difficulty in feeding, drowsiness, or muscle weakness in the newborn infant.

Benzodiazepines given just before or during labor may cause weakness in the newborn infant. When diazepam is given in high doses (especially by injection) within 15 hours before delivery, it may cause breathing problems, muscle weakness, difficulty in feeding, and body temperature problems in the newborn infant.

Breast-feeding

Benzodiazepines may pass into the breast milk and cause drowsiness, difficulty in feeding, and weight loss in nursing babies of mothers taking these medicines.

  • Take the entire mixture right away. It should not be saved to be used later.

For patients taking lorazepam sublingual tablets:

  • Do not chew or swallow the tablet. This medicine is meant to be absorbed through the lining of the mouth. Place the tablet under your tongue (sublingual) and let it slowly dissolve there. Do not swallow for at least 2 minutes.

For patients taking alprazolam oral disintegrating tablets:

  • Make sure your hands are dry. Just prior to taking the tablet, remove the tablet from the bottle. Immediately place the tablet on top of the tongue. The tablet will dissolve in seconds, and you may swallow it with your saliva. You do not need to drink water or other liquid to swallow the tablet. If you have split apart a tablet and only taken one half of the tablet, you should throw away the unused part of the tablet right away because it may not remain stable.

Take this medicine only as directed by your doctor . Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. If too much is taken, it may become habit-forming (causing mental or physical dependence).

Precautions While Using This Medicine:

If you will be taking a benzodiazepine regularly for a long time:

  • Your doctor should check your progress at regular visits to make sure that this medicine does not cause unwanted effects. If you are taking a benzodiazepine for convulsions (seizures), this is also important during the first few months of treatment.
  • Check with your doctor at regular visits to see if you need to continue taking this medicine.

If you are taking a benzodiazepine for epilepsy or another seizure disorder:

  • Your doctor may want you to carry a medical identification card or bracelet stating that you are taking this medicine.

If you are taking a benzodiazepine for insomnia (trouble in sleeping):

  • If you think you need this medicine for more than 7 to 10 days, be sure to discuss it with your doctor. Insomnia that lasts longer than this may be a sign of another medical problem.
  • You may have difficulty sleeping (rebound insomnia) for the first few nights after you stop taking this medicine.

Benzodiazepines may be habit-forming (causing mental or physical dependence), especially when taken for a long time or in high doses. Some signs of dependence on benzodiazepines are:

  • A strong desire or need to continue taking the medicine
  • A need to increase the dose to receive the effects of the medicine.
  • Withdrawal effects (for example, irritability, nervousness, trouble in sleeping, abdominal or stomach cramps, trembling or shaking) occurring after the medicine is stopped.

If you think you may have become mentally or physically dependent on this medicine, check with your doctor. Do not stop taking it suddenly.

If you have been taking this medicine in large doses or for a long time, do not stop taking it without first checking with your doctor. Your doctor may want you to reduce gradually the amount you are taking before stopping completely. Stopping this medicine suddenly may cause withdrawal side effects, including seizures. Stopping this medicine suddenly is most likely to cause seizures if you have been taking it for epilepsy or another seizure disorder.

This medicine will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. This effect may last for a few days after you stop taking this medicine. Check with your doctor before taking any of the above while you are taking this medicine.

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Taking an overdose of a benzodiazepine or taking alcohol or other CNS depressants with the benzodiazepine may lead to unconsciousness and possibly death. Some signs of an overdose are continuing slurred speech or confusion, severe drowsiness, severe weakness, and staggering.

Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of the metyrapone test may be affected by chlordiazepoxide.

If you develop any unusual and strange thoughts or behavior while you are taking this medicine, be sure to discuss it with your doctor. Some changes that have occurred in people taking this medicine are like those seen in people who drink alcohol and then act in a manner that is not normal. Other changes may be more unusual and extreme, such as confusion, agitation, and hallucinations (seeing, hearing, or feeling things that are not there).

This medicine may cause some people, especially older persons, to become drowsy, dizzy, lightheaded, clumsy or unsteady, or less alert than they are normally. Even if taken at bedtime, it may cause some people to feel drowsy or less alert on arising. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert.
