Nitroglycerin Dose

When determining your dose of nitroglycerin (Minitran™, Nitro-Bid®, Nitro-Dur®, Nitrolingual®, NitroMist®, Nitrostat®, Rectiv™), your healthcare provider will consider several factors. Some of these factors that may affect your dosage include the particular nitroglycerin product being used and how you respond to the drug.
The patches, ointment, and capsules are used to prevent angina (chest pain), and are typically used on a daily basis. However, it is important that your body gets a 10- to 12-hour break from the drug every day. Without this break, your body will quickly become accustomed to the effects of nitroglycerin, and the drug will become completely ineffective within 24 hours.
For the tablets and spray, which are approved to treat angina that has already started, you can use up to three doses within 15 minutes. If chest pain continues after a third dose, you may be having a heart attack and you should seek immediate medical care.
