ATNAA Dosage

Self-Aid

1. Administer one (1) ATNAA into your lateral thigh muscle or buttocks as follows:
   1. Remove gray safety cap from back end.
   2. Place front end on outer thigh and push hard until injector functions.
      Hold firmly in place for ten seconds.
   3. Using a hard surface, bend needle into hook. Push ejected needle through a pocket flap (or other thick and conspicuous part of outer clothing).
2. Wait 10 to 15 minutes for the antidote to take effect. If you are able to ambulate, know who you are, and where you are, you will NOT need a second injection. Warning: Giving yourself a second set of injections may cause an overdose of the ATNAA which could result in incapacitation.
3. If symptoms of nerve agent poisoning are not relieved after administering one injection, seek someone else to check your symptoms. A buddy must administer the second and third injections, if needed.
