Final answer:
To prevent sudden dizziness when on Losartan (Cozaar), patients should rise slowly from sitting or lying positions (orthostatic hypotension precautions) and stay well-hydrated.
Step-by-step explanation:
Losartan (Cozaar), an Angiotensin II Receptor Antagonist (ARB), is commonly prescribed to treat high blood pressure. To prevent sudden dizziness, a practical measure is for the patient to make slow and deliberate movements when transitioning from a seated or lying position to standing. This precaution is known as 'orthostatic hypotension precautions.' It minimizes the risk of dizziness or lightheadedness caused by the blood pressure medication. Losartan, along with other ARBs like Telmisartan (Micardis) and Valsartan (Diovan), can cause relaxation of blood vessels, which can result in a temporary drop in blood pressure upon standing, leading to dizziness.
Patients should be advised to take their time when changing positions and to sit up for a few moments before standing to allow the body to adjust. It is also beneficial for the patient to stay well-hydrated and to avoid sudden changes in posture.
