Benzodiazepines, like many other sedative hypnotic drugs, cause apoptotic neuronal cell death. However, benzodiazepines do not cause as severe apoptosis to the developing brain as alcohol does. [105] [106] [107] The prenatal toxicity of benzodiazepines is most likely due to their effects on neurotransmitter systems, cell membranes and protein ...
As a side effect of medicines or recreational drugs, hypoventilation may become potentially life-threatening.Many different central nervous system (CNS) depressant drugs such as ethanol, benzodiazepines, barbiturates, GHB, sedatives, and opioids produce respiratory depression when taken in large or excessive doses, or mixed with other depressants.
Benzodiazepines require special precaution if used in the elderly, during pregnancy, in children, alcohol or drug-dependent individuals and individuals with comorbid psychiatric disorders. [80] Because of their muscle relaxant action, benzodiazepines may cause respiratory depression in susceptible individuals.
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
In older children (above 3.4 years), the tendency appears to be reversed in this study. [19] Nitrazepam may cause sudden death in children. It can cause swallowing incoordination, high-peaked esophageal peristalsis, bronchospasm, delayed cricopharyngeal relaxation, and severe respiratory distress necessitating ventilatory support in children.
In a Swedish (2003) study benzodiazepines were implicated in 39% of suicides by drug poisoning in the elderly 1992–1996. Nitrazepam and flunitrazepam accounted for 90% of benzodiazepine implicated suicides. In cases where benzodiazepines contributed to death, but were not the sole cause, drowning, typically in the bath, was a common method used.

Benzodiazepines may also cause or worsen depression. [20] Infusions or repeated intravenous injections of diazepam when managing seizures, for example, may lead to drug toxicity, including respiratory depression, sedation, and hypotension. Drug tolerance may also develop to infusions of diazepam if it is given for longer than 24 hours. [20]
