# For Heart Attack | |
If you suspect someone is having a heart attack, give 1 tablet of | |
aspirin right away (300 to 325 mg). Ask the person to chew it up and | |
swallow it with water. Even if you are not sure the person is having | |
a heart attack, aspirin will do no harm. On the way to a hospital, | |
give nitroglycerin if you have it. | |
You can also give morphine to help with the pain and fear. | |

# Nitroglycerin (Glyceryl trinitrate) | |
Nitroglycerin is used to treat chest pain from a heart attack. It | |
helps to widen the blood vessels making it easier for the heart to | |
pump blood. | |
## Important! | |
Do not give nitroglycerin to someone with low blood pressure or who | |
has taken sildenafil (Viagra) in the last 24 hours. This combination | |
of medicines can cause blood pressure to drop dangerously low, and | |
can be deadly. | |
## Side effects | |
May cause severe headache, feeling hot, or dizziness. | |
## How to use | |
Pill | |
The person should sit or lie down, not stand up, in case they get | |
dizzy. | |
Give 1/2 mg (0.5 mg) tablet dissolved under the tongue, no more than | |
3 times, waiting 5 minutes between each tablet. If the chest pain | |
and other signs go away, another tablet is not needed. Do not chew | |
or swallow nitroglycerin tablets. As the tablet dissolves under the | |
tongue, it tingles or even burns a little. | |
