How long will nitroglycerin last once the bottle is opened? I've had some nurses say 2 weeks and others say 30 days. Thanks

I'd ask your pharmacist. This is what they do best.

According to various sources, Nitroglycerin tablets will remain potent for a period of three months after the bottle has been opened. The pills are used to increase blood flow to the heart muscle especially during periods of angina. Read more from http://www.uofmmedicalcenter.org/healthlibrary/Article/116338EN.

The nurses are probable going by the policy of the facility they work in. Remember more people are opening and handling the pills than you would at home. I suggest you read the product insert or contact the manufacturer of your particular product for guidelines.
