Blood Pressure Medications: Types, Benefits, and Side Effects
High blood pressure affects nearly half of all adults. Learn about the different classes of medications used to treat it and what to expect from each.
Why Blood Pressure Treatment Matters
High blood pressure, or hypertension, is a leading risk factor for heart attack, stroke, kidney disease, and heart failure. Often called the "silent killer" because it typically has no symptoms, hypertension requires consistent treatment and monitoring to keep levels in a safe range.
ACE Inhibitors
Angiotensin-converting enzyme (ACE) inhibitors, such as lisinopril and enalapril, work by relaxing blood vessels. They are often prescribed as a first-line treatment and are particularly beneficial for patients with diabetes or kidney disease. A common side effect is a persistent dry cough, which affects about 10 to 15 percent of patients.
ARBs (Angiotensin Receptor Blockers)
ARBs, such as losartan and valsartan, work similarly to ACE inhibitors but are less likely to cause a cough. They are frequently prescribed as an alternative for patients who cannot tolerate ACE inhibitors. ARBs are also protective for the kidneys and heart.
Calcium Channel Blockers
Medications like amlodipine and diltiazem relax and widen blood vessels by preventing calcium from entering heart and blood vessel cells. They are effective for lowering blood pressure and are often well-tolerated. Possible side effects include swelling in the ankles and constipation.
Diuretics
Diuretics, often called "water pills," help the kidneys remove excess sodium and water from the body, reducing blood volume and lowering pressure. Hydrochlorothiazide and chlorthalidone are commonly prescribed. Side effects may include increased urination and low potassium levels.
Beta-Blockers
Beta-blockers like metoprolol and atenolol slow the heart rate and reduce the force of heart contractions. While effective, they are now typically used alongside other medications rather than as a sole first-line treatment. Side effects can include fatigue, cold hands, and weight gain.

- Monitor your blood pressure at home regularly
- Report side effects promptly so your doctor can adjust your treatment
