How many nitroglycerine tablets can you take before calling the doctor?

The correct answer is based on guidelines for the use of nitroglycerin in managing angina pectoris or chest pain. Patients are typically advised to take one nitroglycerin tablet at the onset of chest pain. If the pain persists after five minutes, they can take a second tablet. If, after another five minutes, the pain remains unchanged, a third tablet may be taken.

This protocol indicates that up to three tablets can be used within a 15-minute period before urgent medical attention should be sought, as chest pain may signify a heart attack or other serious cardiac issue. If chest pain persists after three doses, the patient should call for emergency medical help or consult their physician. Understanding this protocol highlights the importance of monitoring the patient's reaction to the medication and recognizing the signs that require immediate medical intervention.
