What should I do if I forget a dose?
If you are taking nitroglycerin only as needed, missing a dose is not a problem. Use nitroglycerin only when you experience an angina attack.
If you are taking nitroglycerin to prevent angina attacks, take the missed dose as soon as you remember. If you are taking the regular tablets (not the extended-release tablets) and your next regularly scheduled dose is within 2 hours, skip the dose you missed and take only the next dose. If you are taking the extended-release tablets and your next regularly scheduled dose is within 6 hours, also skip the missed dose and take only the next dose.
Do not take a double dose of this medication.
