==Effects of exposure==
The symptoms of exposure include:<ref name="cbw">{{cite web |title=Nerve Agent: GA |url=http://www.cbwinfo.com/Chemical/Nerve/GA.shtml |url-status=dead |archive-url=https://web.archive.org/web/20110927051929/https://www.cbwinfo.com/Chemical/Nerve/GA.shtml |archive-date=2011-09-27 |access-date=2008-11-06 |publisher=Cbwinfo.com}}</ref><ref name=military>{{cite web |url=http://usmilitary.about.com/library/milinfo/blchemical-3.htm |title=Chemical Warfare Weapons Fact Sheets&nbsp;— Tabun&nbsp;— GA Nerve Agent |publisher=Usmilitary.about.com |access-date=2008-11-06 |url-status=dead |archive-url=https://web.archive.org/web/20160303185700/http://usmilitary.about.com/library/milinfo/blchemical-3.htm |archive-date=2016-03-03 }}</ref><ref name=ency>{{Cite web|url=https://www.encyclopedia.com/science-and-technology/chemistry/organic-chemistry/tabun#3403300733|title=Tabun &#124; Encyclopedia.com|website=www.encyclopedia.com}}</ref> [[Anxiety|nervousness]]/[[anxiety|restlessness]], [[miosis]] (contraction of the pupil), [[rhinorrhea]] (runny nose), excessive salivation, [[dyspnea]] (difficulty in breathing due to [[bronchoconstriction]]/secretions), [[sweating]], [[bradycardia]] (slow heartbeat), [[Syncope (medicine)|loss of consciousness]], [[convulsion]]s, [[flaccid paralysis]], loss of bladder and bowel control, [[apnea]] (breathing stopped) and lung blisters. The symptoms of exposure are similar to those created by all [[nerve agent]]s. Tabun is toxic even in minute doses. The number and severity of symptoms which appear vary according to the amount of the agent absorbed and rate of entry of it into the body. Very small skin dosages sometimes cause local sweating and tremors accompanied with characteristically constricted pupils with few other effects. Tabun is about half as toxic as [[sarin]] by inhalation, but in very low concentrations it is more irritating to the eyes than sarin. Tabun also breaks down slowly, which after repeated exposure can lead to [[Bioaccumulation|build up in the body]].<ref name="nta">[http://www.nationalterroralert.com/tabun Facts About Tabun], National Terror Alert Response System</ref>

The effects of tabun appear slowly when tabun is absorbed through the skin rather than inhaled. A victim may absorb a lethal dose quickly, although death may be delayed for one to two hours.<ref name=military/> A person's clothing can release the toxic chemical for up to 30 minutes after exposure.<ref name="nta"/> Inhaled lethal dosages kill in one to ten minutes, and liquid absorbed through the [[Human eye|eye]]s kills almost as quickly. However, people who experience mild to moderate exposure to tabun can recover completely, if treated almost as soon as exposure occurs.<ref name="nta"/> The [[median lethal dose]] ([[LD50|LD<sub>50</sub>]]) for tabun is about 400&nbsp;mg-min/m<sup>3</sup>.<ref>{{cite web|url=http://www.atsdr.cdc.gov/MHMI/mmg166.html |archive-url=https://web.archive.org/web/20030423050312/http://www.atsdr.cdc.gov/MHMI/mmg166.html |url-status=dead |archive-date=April 23, 2003 |title=ATSDR&nbsp;— MMG: Nerve Agents: Tabun (GA); Sarin (GB); Soman (GD); and VX |publisher=Atsdr.cdc.gov |access-date=2008-11-06}}</ref>

The lethal dose for a man is about .01 mg/kg. The median lethal dose for respiration is 400 mg-minute/m3 for humans. When absorbed via the skin, death may occur in 1-2 minutes, or it can take up to 2 hours.<ref name="PubChem 6500 Tabun"/>

Treatment for suspected tabun poisoning is often three injections of a nerve agent antidote, such as [[atropine]].<ref name="ency"/> [[Pralidoxime chloride]] (2-PAM Cl) also works as an antidote; however, it must be administered within minutes to a few hours following exposure to be effective.<ref>Emergency Response Safety and Health Database.
