How often should you self-inject ATNAA treatment when experiencing continued symptoms of nerve agent exposure?

The correct approach for self-injecting ATNAA (Antidote Treatment Nerve Agent Auto-Injector) during continued symptoms of nerve agent exposure is to administer it every 5 minutes as needed. This frequency allows for a timely response to the potentially life-threatening effects of nerve agents, which can rapidly progress.

When exposed to a nerve agent, symptoms can escalate quickly, making it crucial to act swiftly. The 5-minute interval provides the necessary balance between ensuring effectiveness and preventing overdose from the antidote. Other options are less effective; a 10-minute wait could allow symptoms to worsen dangerously, once an hour would be far too infrequent, and simply injecting when symptoms worsen might not provide adequate protection as there could be a delay in mitigating the effects of the agent already affecting the body.
