====Discontinuation====
===Overdose===
Benzodiazepine discontinuation is notoriously difficult; it is potentially life-threatening for individuals using regularly to discontinue use without tapering their dose over a period of weeks. There is an increased risk of [[high blood pressure]], [[seizures]], and death.<ref>A fatal case of benzodiazepine withdrawal. (PubMed.gov / NCBI) | http://www.ncbi.nlm.nih.gov/pubmed/19465812</ref> Drugs which lower the seizure threshold such as [[tramadol]] should be avoided during withdrawal. Abrupt discontinuation also causes rebound stimulation which presents as [[anxiety]], [[wakefulness|insomnia]] and restlessness.
{{BenzoOD}}


It is safest to reduce the dose each day by a very small amount, for a couple of weeks until close to abstinence. If using a short half-life benzodiazepine, a longer acting variety such as [[diazepam]] can be substituted. Symptoms may still be present, but their severity will be reduced significantly. For more information on tapering from benzodiazepines in a controlled manner, please see [http://www.benzo.org.uk/manual/bzcha02.htm this guide]. Small amounts of [[alcohol]] can also help to reduce the symptoms.
===Discontinuation===
{{BenzoDiscontinuation}}


The duration and severity of withdrawal symptoms depends on a number of factors including the half-life of the drug used, tolerance and the duration of abuse. Major symptoms will usually start within just a few days after discontinuation and persist for around a week for shorter lasting benzodiazepines. Benzodiazepines with longer half-lives will exhibit withdrawal symptoms with a slow onset and extended duration.
