Many patients will not develop these side effects, although there is still a significant possibility of risks associated with Antipsychotic usage. The percentage of patients affected by side effects like Tardive dyskinesia is significantly high and estimated to be a 20-50% prevalence. [1] [2]
[81] [82] Concerns regarding the long-term effects of benzodiazepines have been raised since 1980. [83] These concerns are still not fully answered. A review in 2006 of the literature on use of benzodiazepine and nonbenzodiazepine hypnotics concluded that more research is needed to evaluate the long-term effects of hypnotic drugs. [84]
One view is that many of the short-term effects continue into the long-term and may even worsen, and are not resolved after stopping benzodiazepine usage. Another view maintains that cognitive deficits in chronic benzodiazepine users occur only for a short period after the dose, or that the anxiety disorder is the cause of these deficits.

[13] The main side-effects include: a feeling of sleepiness and tiredness, decreased blood pressure, nausea, vomiting and also glaucomatous visual hallucinations.
Active metabolites are produced when a person's body metabolizes the drug into compounds that share a similar pharmacological profile to the parent compound and thus are relevant when calculating how long the pharmacological effects of a drug will last. Long-acting benzodiazepines with long-acting active metabolites, such as diazepam and ...
This list is not limited to drugs that were ever approved by the FDA.

Long-term use of nitrazepam may carry mental and physical health risks, such as the development of cognitive deficits. These adverse effects show improvement after a period of abstinence. [ 21 ] [ 22 ] Some other sources however seem to indicate that there is no relation between the use of benzodiazepine medication and dementia. [ 23 ]
