When using sublingual tablets for angina, how often should a client use a tablet during an acute attack?

When a client experiences an acute angina attack and uses sublingual tablets, the recommended frequency of administration is every 5 minutes as needed, up to a maximum of three tablets within a 15-minute period. This rapid administration is critical because it allows for quick relief of angina symptoms. The sublingual route ensures that the medication is absorbed quickly into the bloodstream, providing prompt relief from chest pain.

If symptoms persist after using three tablets in 15 minutes, it is advisable to seek medical attention, as this could indicate that the angina episode is more serious, such as a potential myocardial infarction. Understanding this time frame is essential for effective management of acute angina episodes, emphasizing the importance of timely intervention and appropriate use of medication.
