    Does nitroglycerin tablets lose potency once opened? I found a bottle containing nitroglycerin tablets from last year in one of my cupboards while I was cleaning the kitchen. Will these tablets still be potent and can be used?

    Nitroglycerin is a substance that easily evaporates from the tablet if not properly stored. A study shows that when tablets are kept in a small, amber, tightly capped glass bottle and stored in a refrigerator, the medicine is able to maintain the potency for three to five months if bottles are opened once a week. In your case, since your tablets are from last year, it has exceeded the 3-5 months allowance and considering that it has been left in a cupboard in your kitchen, the heat from the environment could have already damaged your tablets. It would be best to get new tablets to ensure potency.
