Which information should you warn a patient about when starting an antihypertensive?

• A. Hair loss
• B. Dizziness and orthostatic effects
• C. Increased appetite
• D. Hives always

Answer: (B)

Starting antihypertensive therapy typically lowers blood pressure, so the most important warning for a patient to understand is that dizziness and lightheadedness can occur, especially when standing up. This orthostatic effect happens because the medication lowers blood pressure and the body needs time to adjust to the new level. To stay safe, rise slowly from sitting or lying down, sit back down if you feel dizzy, and avoid driving or operating heavy machinery until you know how you respond. Older adults or those taking diuretics may be more susceptible, so monitor symptoms and blood pressure as advised and contact a clinician if dizziness persists, you faint, have chest pain, or notice sudden or severe changes. Hair loss, increased appetite, or hives are not the typical warnings when starting these drugs. Hair loss is not a common early side effect for most antihypertensives, increased appetite isn’t typical, and hives would indicate an allergic reaction requiring different attention.
