Answer

If nitroglycerin is prescribed to a patient with suspected ACS, the patient should be instructed to take a dose if symptoms arise. If no relief is experienced 5 minutes after the first dose, the patient should contact emergency services. If relief is experienced within 5 minutes of the first nitroglycerin dose, repeated doses can be given every 5 minutes for a maximum of 3 doses total. If by then the symptoms have not yet fully resolved, the patient, a family member, or a caregiver should contact emergency services. [1]
