feel angina coming on, stop what you are doing, sit down, rest and
wait until the feeling passes. If you have been given GTN (glyceryl
trinitrate) tablets or spray, use as instructed.
If the angina
persists, you can repeat the dose of tablets or spray safely three
times, once every five minutes. Resume your activities gently once
the symptoms have passed.
If the angina is
not relieved after rest or three doses of your medication in 15
minutes, call an ambulance: dial
If you get angina at predictable times, use your spray or
tablets a few minutes before attempting that activity. If you have
angina symptoms every day, worsening angina symptoms, angina at rest
or at night, or symptoms that are not relieved as easily as usual by
your angina medication, keep using your medication but see your
doctor within 24 hours. These can sometimes be warning signs of an
impending heart attack.
