What is Atnaa?
ATNAA is a combination medicine used as an antidote to treat poisoning by a pesticide (insect spray) or a chemical that interferes with the central nervous system, such as nerve gas.
ATNAA is not effective as an antidote for all types of pesticide poisonings. You may need medications or additional treatments.
ATNAA may also be used for purposes not listed in this medication guide.
Warnings
In an emergency, you may not be able to tell caregivers about your health conditions. Make sure any doctor caring for you afterward knows you received ATNAA.
How should I use Atnaa
ATNAA is injected into a muscle in your upper thigh. A healthcare provider will give you this injection.
ATNAA is usually given as soon as possible after the onset of poisoning symptoms. If you still have symptoms after 10 to 15 minutes, you will receive 2 more injections.
Your breathing, blood pressure, oxygen levels, kidney function, and other vital signs will be watched closely.
You may be watched for up to 72 hours to make sure the medicine has been effective and you no longer have any effects of the poison.
Before Taking
If possible, before you receive ATNAA, tell your doctor if you have ever had:
-
an allergy to any medication;
-
heart problems, a heart attack or stroke;
-
high blood pressure;
-
liver or kidney disease;
-
asthma, COPD (chronic obstructive pulmonary disorder), or other breathing problem;
-
glaucoma; or
-
urination problems.
In an emergency situation it may not be possible to tell your caregivers if you are pregnant or breast-feeding. Make sure any doctor caring for your pregnancy or your baby knows you have received this medicine.
What happens if I miss a dose?
Since ATNAA is used when needed, it does not have a daily dosing schedule.
What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
Overdose may occur if you receive ATNAA but you have not actually been exposed to the specific poisons this medication is designed to treat. Symptoms may include vision problems, feeling unsteady, loss of balance or coordination, trouble concentrating, fast heart rate, confusion, hallucinations (seeing or hearing things), decreased sweating, hot and dry skin, fainting, weak or shallow breathing, or breathing that stops.
What should I avoid while using Atnaa?
Avoid becoming overheated or dehydrated during exercise and in hot weather. Atropine can decrease sweating and you may be more prone to heat stroke for a short time after receiving this medication.
