I am intolerant to nitrates, side effects from just 5mg is nausea, dizziness to the point of falling over, shakes, chronic headaches. On top of this, the medication does nothing for
my angina. It is all very well a doctor saying you have to live with it, but at what cost. As you say, the headaches are bad and I have personally felt these, they are nasty. It feels
like all the nerves in your neck are being squeezed causing shooting pains in the head.
I would seek a second opinion because there is quite a good variety of nitrate drugs.
Doctors are recommended to start Imdur on a low dose and gradually build it up so the
body can adapt over several weeks. It is believed that there are certain triggers for a spasm such as cold air, alcohol abuse, cocaine and smoking. Other triggers are not
known. I would definitely seek a second opinion.
