Which instruction is important for a patient being prescribed propranolol for hypertension at discharge?

The instruction to not stop taking the medication abruptly is crucial for a patient prescribed propranolol for hypertension. Propranolol is a beta-blocker that helps manage blood pressure and can also affect heart rate and the body's response to stress hormones. When a patient suddenly discontinues the medication, it can lead to withdrawal symptoms such as rebound hypertension, which can be a rapid increase in blood pressure, as well as an increased risk of heart-related complications.

Tapering off the medication gradually, under a healthcare provider's guidance, helps to minimize these risks and allows the body to adjust properly. Patients should always be educated about the importance of adherence to the prescribed regimen and the potential consequences of abrupt discontinuation. This understanding helps ensure effective management of their condition and enhances safety.

Other options suggest practices that are not appropriate for managing blood pressure with propranolol, such as taking the medication only when blood pressure is high, which is contrary to the need for consistent blood pressure management. A high-sodium diet and reducing fluid intake can negatively affect blood pressure regulation and overall health. Hence, the focus on proper medication management is vital for patient safety and health outcomes.
