i  use it  if     i get chest pains from highBP at night but how often can yiu use it and is it safe ???

 

how  easy is it to buy over the counter ??

As far as I know nitroglycerine itself  is not available in Thailand. 

 

You can however get  isosorbide in both spray and (more common) sublingual form.  

 

Different drug but similiar action.

AFAIK not available as spray, neither glyceryl trinitrate nor isosorbide.

Sublingual tablets are easily available OTC.

 

Dosage of the spray: 1-3 puffs - you should have discussed this with your doctor! If you need it regularly, switch to oral tablets.

It is pretty safe if you don't overdo it. Signs of overdosage: headache, dizzyness, rapid heartbeat, fainting.

Don't drive, it makes you light-headed.

Do not combine with viagra or cialis (and their generics), people die from doing this. 24 hours between nitro and these meds!

 

Altogether, you should discuss this med with your doctor,  and you should discuss your BP with him, too. Because your BP is not safe.

There is a spray form of isosorbide available (though can be hard to locate) 

 

Agree though that if indeed the pain is from high blood pressure (actually sounds more like angina to me), better ongoing medical control is needed.

 

I assume OP is already under the care of a cardiologist. If not, should be.
