When teaching about translingual nitroglycerin for angina, what safety information should be emphasized?

Translingual nitroglycerin is used sublingually or as a spray for the rapid treatment of angina. When using a translingual spray, it is crucial to direct the spray carefully under the tongue. This is important because the medication is absorbed through the mucous membranes in the mouth, and proper placement ensures that it is delivered where it can be most effective. If sprayed incorrectly, the medication may not be absorbed adequately, leading to reduced efficacy in relieving angina symptoms.

The emphasis on directing the spray carefully ensures that the patient receives the correct dosage and maximizes the medication's effectiveness. Proper administration also minimizes the risk of it being accidentally inhaled or sprayed onto unintended areas, which could lead to unwanted side effects or inadequate treatment.
