Pregnancy and Breast-feeding Warnings [top]
Pregnancy Warning
An increased risk of congenital malformations associated with the use of minor tranquilizers (diazepam, meprobamate, and chlordiazepoxide) during the first trimester of pregnancy has been suggested in several studies. Because use of these drugs is rarely a matter of urgency, their use during this period should almost always be avoided. The possibility that a woman of childbearing potential may be pregnant when beginning therapy should be considered. Patients should be advised that if they become pregnant during therapy or intend to become pregnant, they should communicate with their physicians about the desirability of discontinuing the drug.
Breast-feeding Warning
Benzodiazepines are excreted in breast milk. Taking a benzodiazepine (diazepam) caused nursing infants to become lethargic and lose weight. As a general rule, mothers taking benzodiazepines, including Xanax, should not nurse.
Safety Warnings For This Drug [top]
FDA BLACK BOX WARNING
Using benzodiazepines and opioids together may result in profound sedation, respiratory depression (markedly decreased breathing), coma, and death.
If you are currently taking zolpidem and develop complex sleep behaviors, discontinue the drug immediately and seek medical help.
Otherwise, if you have been taking zolpidem for awhile, do not stop taking this drug suddenly because it may cause drug-induced dependence. Instead, work with your doctor to create a schedule to stop it gradually to avoid withdrawal reactions (including stomach cramps, vomiting, nervousness and panic attacks).
The best way to reduce the risks from sleeping pills and tranquilizers is to avoid them if at all possible. Before taking one of these powerful medications, see the Sleeping Pills and Tranquilizers section of this site for nondrug alternatives to try before using either sleeping pills or tranquilizers.
Warning: Do Not Use Alprazolam (XANAX) Except for Panic Disorder
Panic Disorder and related conditions must be evaluated by the appropriate mental health professional. Specialized psychotherapy decreases the need for drugs for this condition. A psychiatrist may be able to prescribe less hazardous medications for this condition.
Facts About This Drug [top]

Do Not Use: This drug is sedating, addictive and causes hip fractures. Safer drugs are available.
The 13 sleeping pills and tranquilizers discussed in this profile all belong to the benzodiazepine family. Called sedative hypnotic drugs, and sometimes referred to as sleeping pills, they are used to induce or maintain sleep and to treat acute anxiety. Although these drugs are widely used by older adults, they present significantly higher risks to people over 60, and many older people who use these drugs should not be taking them. These drugs have significant risks and often are prescribed unnecessarily.
Some of these sleeping pills stay in the body so long that patients remain sedated during the daytime, whereas other drugs in this family leave the body so quickly that patients can experience rebound insomnia and become confused the following day. Further, benzodiazepines lack proven long-term benefits.
Adverse effects
Benzodiazepines can cause unsteady gait, dizziness, falling (which increases the risk of hip fractures), automobile accidents (which may cause injury), cognitive impairment, memory loss and addiction.
There have been reports of sleepwalking (inappropriate or strange automatic behavior while asleep, including binge eating and house painting) and serious allergic reactions in patients using sleeping pills such as estazolam (PROSOM), flurazepam (DALMANE), quazepam (DORAL), temazepam (RESTORIL) and triazolam (HALCION).[1]
Risk of hip fracture
Available evidence strongly suggests that the use of benzodiazepines in older people increases their risk of hip fracture by at least 50%.[2] Due to the high morbidity and mortality associated with hip fracture, older people should rarely be prescribed benzodiazepines. Many older people already taking these drugs should withdraw from them under appropriate medical supervision.[3]
Hallucinations
Visual hallucinations with temazepam use have been reported. These hallucinations stopped when temazepam use was stopped.[4]
Dementia
A study published in the British Medical Journal provides the strongest evidence to date linking benzodiazepine use to an increased risk of dementia. This large, carefully conducted study used a prospective design and avoided some of the key weaknesses of earlier studies. The authors found that benzodiazepine use by elderly patients increased the risk of developing dementia by approximately 40-60%.
Worst Pills, Best Pills News categorizes all of the benzodiazepines approved for anxiety or insomnia in the U.S. as "Do Not Use" drugs, with the exception of alprazolam (NIRAVAM, XANAX XR, XANAX), which is listed as "Do Not Use" except for panic attacks.
Studies show...
Our review of the benzodiazepine drugs reveals that they are all effective; however, each drug has a different degree of safety.
High incidence of adverse effects with flurazepam
According to the World Health Organization, older adults should not use flurazepam “owing to a high incidence of adverse effects.”[5]
Drugs can leave body too quickly or too slowly
Some benzodiazepines are cleared out of the body very slowly, especially in older adults. As a result, they can accumulate in the body, resulting in a greater risk of adverse events. This effect is particularly evident for the following drugs: diazepam (VALIUM), chlordiazepoxide (LIBRIUM), clorazepate (TRANXENE), prazepam (CENTRAX), halazepam (PAXIPAM), quazepam and estazolam.
In contrast, triazolam is very short-acting, and it can cause rebound insomnia (increased sleeping problems when the drug effect has worn off); anxiety; serious amnesia (forgetfulness or memory loss); and violent, aggressive behavior.
Increased risk of death
A March 2014 study in the United Kingdom found an increase in the risk of death in people using tranquilizers or sleeping pills compared with people not using them. The results were similar to those from a 2012 study. Concerns about the effect of these drugs on premature mortality have been fueled by studies documenting increased risk of dementia, daytime fatigue, lack of coordination, falls, road traffic incidents, and pneumonia and other infections.[6]
Link to Alzheimer's disease
The April 2015 issue of Worst Pills, Best Pills News highlighted information from a 2014 article in the journal JAMA Psychiatry that found that benzodiazepines were overprescribed in the U.S. It also highlighted a 2014 study in the British Medical Journal that found a link between benzodiazepine use and Alzheimer’s disease in elderly patients.[7]
Best options for older adults
Some experts believe oxazepam and temazepam are the drugs of choice for older patients.[8] Public Citizen does not recommend using either of them.
One suitable alternative for patients who require a tranquilizer for acute anxiety is the non-benzodiazepine buspirone (BUSPAR), which we have designated Limited Use.
Patients taking a tranquilizer for anxiety should ask their doctors to re-evaluate the need for this drug. If patients do need such a drug, they should be taking buspirone.
Prazepam and halazepam are no longer officially marketed in the U.S., either because they were withdrawn for safety reasons or because their manufacturers discontinued their production.[9]
A placebo-controlled clinical trial published in 2019 found that use of valium in the evening before bedtime significantly increased blood pressure and heart rate during the night in healthy elderly individuals.[10]
Regulatory actions surrounding benzodiazepines
1992: Public Citizen’s Health Research Group petitioned the Food and Drug Administration (FDA) to ban triazolam because it is very similar to the sleeping pill estazolam, which was already on the market. The two drugs are in the same chemical subclass. According to the highly regarded Medical Letter on Drugs and Therapeutics, there is no reason to use triazolam.[11]
2007: In March, the FDA asked manufacturers of these drugs to update the drug product labels concerning potential risks associated with these medications, including “severe allergic reactions and complex sleep-related behaviors.” Allergic reactions included anaphylaxis (severe allergic reaction) and angioedema (severe facial swelling). Complex sleep-related behaviors included sleep-driving, making phone calls and preparing and eating food while asleep.
The following medications were specifically mentioned in the FDA advisory:
The FDA also requested that Medication Guides be developed for consumers. The drugs in the benzodiazepine family are a few of a limited number of drugs for which the FDA requires an FDA-approved Medication Guide to be dispensed when the prescription is filled. (Click here to view a list of FDA-approved Medication Guides.) An FDA advisory committee has unanimously recommended that all prescription drugs be accompanied by such Medication Guides, but at present, less than 5% of drugs are. The other 95% of drugs are accompanied by unregulated, often dangerously incomplete information leaflets not approved by the FDA.
2016: In August, the FDA added a black-box warning, the strongest warning used by the FDA, to all opioid and benzodiazepine drugs stating that serious adverse effects — including respiratory depression, coma and death — have occurred when these medications are used together.[13]
