If you miss a dose of Nitroglycerin Patch, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once. When used for long periods of time without a break, some people develop a physical need to continue taking Nitroglycerin Patch. This is known as physical DEPENDENCE. Do not suddenly stop taking Nitroglycerin Patch without your doctor's approval.
I still had stable angina every time I did some for of cardio activity or is I ate something with sodium. I started using Nitroglycerin patches and even have the pills just in case my angina episode occurs.
I had a date and I read online that you can't take viagra and any nitrates cause it can drop your blood pressure really low. So I stopped using my nitroglycerin for about 48 hours so I can take the Viagra.
Most everything lasts a while past expiration before deterioration, including food. Expiration dates have a margin of safety built in. That being said, the above is true, but vitamins usually have way more that anyone needs in them so a little deterioration in potency isn't that big a deal depending on why you're taking them. After all, much of them just goes down the toilet anyway, so again, a margin of safety is built in there, too.
ed is correct nitro dilates vessels.
I take a nitrate (isosorbide) for more than 6 years 3 times before going to gym for workout. My blood pressure does not drop between intervals...in fact I was told to have intervals of nitrate free period. It is true, nitro dilates the coronary vessels and prevents angina (chest pain). The patch should only be worn for up to 12 to 14 hours a day, or as directed by your doctor, but continued use with no interruptions can cause a tolerance for drug....
I only take isosorbide prior to a workout, and nitro when engaged in an activity that brings on angina. I understand your doctors are suggesting taking isosorbide daily as aschemia does not always produce angina even though the heart cells are not getting sufficient blood supply. This can lead to a silent heart attack so the medication is recommended continuously whether there is angina or not and older people in general are likely to have a silent heart attack.
The pain lasts anywhere from a few minutes to several hours. I have been prescribed nitroglycerin to take as needed for chest pain and this medicine surely helps. I've had several EKGs and cardiac enzymes done which were all normal. I also had a threadmill/stress test done which was normal. My cardiologist thinks the the probability of me having an occluded/blocked coronary artery is very low.
These were precribed to me but I noticed the bottle expiration date is 10/2008. I have almost full bottles so I haven't thrown them out. Can I consider these safe? My husband says yes.
You may want to check and see if there is an expiration date. Even if the expiration date is past, there are still okay to use as the expiration date is for the packaging.
Good luck.
The doctor said the left heart was okay but found a narrowing in the right heart which caused coronary spasms during the test. IV nitroglycerin during the test stopped the spasms and dilated the vessel. He did not mention any other problems and recommended sublingual nitroglycerin to treat the spasms as they occur.
So I just noticed that my last two packs of pills have the expiration date of 7/2009. Im supposed to start one of the packs this sunday, and that means I will be taking 4 days of expired pills (the first four days of July). Will this be risky? I called planned parenthood and they said I would be fine...and that I can't come in and get new packs since I have two...I'm a little scared these pills won't work since its so close to the expiration date!!
Hello and welcome to the forum. Could you give us more details? Normally expiration dates are stated on the pill bottles. Here is some general information. https://www.fda.gov/drugs/pharmaceutical-quality-resources/expiration-dates-questions-and-answers. But you should most certainly check with your provider and a pharmacist.
I've never heard of nitroglycerin being used to treat migraine, but glad that it worked.
But if it keeps on, and sorry to tell you this, but you probably should see a doctor ASAP. It could be the sign of a coming stroke, since it is sudden and very painful. I started with a sudden very different migraine than any I had ever had before. It turned out that within 3 weeks, longer than usual as a gap in time, I had a full carotid artery dissection stroke.
The same with his recent heart catherization was chest pressure. In the ER he was given 2 nitroglycerin, 5 minutes apart, the chest pressure went away after the 2nd nitroglycerin.
Does any good specialist in cardiology think that my husband should have the open heart surgery for bypasses considering the risks regarding his age, his diabetes?
I would appreciate very explanatory answers, easy to understand, what to do in my husband's situation.
Thankyou.
I assume the diagnosis of hyperreactive responses not only to the constrictor effects of acetylcholine, but also the dilator effects of nitroglycerin were detected diffusely in the epicardial coronary arteries of patients with coronary spastic angina.
The goal of treatment is to control chest pain and to prevent heart attack. The pain is relieved by a medicine called nitroglycerin (dilates coronary vessels). You have been prescribed norvasc and that should relieve any chest pains.
There is an abnormal increased velocity involving the celiac artery origin in the supine position with a peak systolic velocity of 294 cm/s, at inspiration 326 cm/s, expiration 406 cm/s. The knee semi-upright position during expiration the velocity is 276 cm/s, upright expiration 147 cm/s."
However, when my doctor followed this test up with an MRA it came back normal. I am confused how this could be.
