1. What Atropine Injection is and what it is used for

Children under 12 years of age:
This medicine is not recommended for children under 12.

Atropine belongs to a group of medicines called antimuscarinics.
These medicines are often used in anaesthesia to reduce the flow of
saliva and other body fluids. Atropine may also act on the vagus
nerve (a nerve that sends information from the brain to other parts of
the body). This helps to make the heart beat faster.

If you think you have been given too much Atropine Injection
This medicine is given to you by your doctor so it is unlikely you will
receive too much. Your doctor has information on how to recognise
and treat an overdose. If you are concerned about your treatment,
please talk to your doctor.

Atropine Injection is used to raise the heart rate if it has become too
slow after a heart attack
