This medication is usually comes in a spray or a tablet.
Why they are used?
Their main use is for resolving angina pain/ discomfort.
How do they work?
GTN preparations enlarge blood vessels, thereby increasing the blood flow to the heart. Reduced blood supply to the heart causes the pain /discomfort known as angina.
When should they be used?
When an angina attack occurs, you should stop what you are doing. If the pain / discomfort persists, use the GTN. The angina should go away completely. Many people know a certain activity will bring on angina actually find it helpful to use the medication before they start.
How should they be used?
They should be either sprayed or placed under the tongue. Wait 5 minutes - if the pain persists use it again. If you have to use it 3 times (a total of 15 minutes) and the pain has still not gone away, you should then call for an ambulance.
Storage of the GTN
Check for an expiry date printed on the spray. Tablets are only effective for 8 weeks after the bottle has been opened. Write the date of opening on your bottle and ensure you have a new bottle before this date. When using the tablets, you should usually get a tingling sensation under the tongue. If you don't, then you may need to change your supply. DO NOT transfer the tablets to any other container. DO NOT mix the tablets with any other drugs. Store them in a cool dark place (not the fridge)
What to look out for
- You may experience a headache. If it doesn't pass, take paracetamol. Don't NOT use it because of the possibility of headaches; it is better to treat the angina and then deal with the headache.
Please carry this medication with you at all times. Viagra should not be taken if you are using GTN.
