Glyceryl Trinitrate Sublingual Spray (GTN) 200 dose: Things you need to know
Glyceryl trinitrate, or GTN, is a type of medicine called nitrate. It is used to treat angina(chest pain).
It can help stop chest pain if an angina attack has already started. It can also help to prevent them from starting.
It comes as tablets or as a spray that you put under your tongue. It also comes as patches and ointment that you put on your skin.
Sometimes GTN patches are used in hospitals to make it your veins easier to see if you need to have a drip (infusion).
Spray – 1 or 2 sprays under your tongue. If you're still in pain after 5 minutes you can have a second dose of 1 or 2 sprays under your tongue. If you're still in pain after 5 minutes you can have a third and final dose.
Do not use more than 3 doses during an angina attack. 1 dose is 1 to 2 sprays under the tongue.
GTN can only be used by adults aged 18 years and above. Do not give it to children.

ever had an allergic reaction to GTN or any other medicine in the past
any recent brain or head injuries or problems (including bleeding in your brain and raised pressure in your head)
ever had a stroke
