Anginal chest pain is usually treated first with a fast-acting medicine called glyceryl trinitrate (GTN). This medicine is commonly given as a small tablet placed under the tongue or as a spray. It helps relax and widen the blood vessels, allowing more blood to reach the heart and relieving pain quickly. When chest pain starts, the person should immediately stop all activity and sit down in a resting position. One dose of GTN should be taken as prescribed by the doctor. If the pain does not improve after about 5 minutes, another dose can be taken. This can be repeated up to three doses in total. If the pain continues even after this, it may be a sign of a serious heart problem, and emergency medical help should be sought without delay. In some cases where a heart attack is suspected, doctors may advise taking chewable aspirin, but only if it was previously recommended. Regular follow-up with a doctor is important to manage angina safely and prevent future episodes.
