Glyceryl trinitrate tablets (GTN)

GTN sublingual tablet is used to either relieve the pain of heart (angina) attacks or to prevent an expected heart attack, such as when you are about to exercise.

The tablet should be used at the first sign of a heart attack. This medicine usually gives relief in less than 5 minutes (Important: Do not wait until severe pain develops)

If your pain becomes worse at any point in time, or if you feel unwell (e.g. dizzy, short of breath, sweaty), call 995 immediately.

You may continue to take 1 GTN tablet every 5 minutes to relieve the attack while waiting for the ambulance.
