High blood pressure or hypertension affects millions of people in the United States. As it presents no noticeable symptoms, high blood pressure is often called a “silent killer.” High blood pressure can lead to severe consequences, including heart attacks, heart failure, and strokes if left untreated. However, high blood pressure is entirely treatable with lifestyle changes and medications. 

Blood pressure medications, also known as antihypertensives, may be prescribed to help control blood pressure. Numerous blood pressure medications may work in various ways. These medications include angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), and beta blockers. The best treatment option will vary depending on your underlying health condition, other medications you may be taking, and other factors.

Commonly prescribed blood pressure medications

High blood pressure medications may work differently to help lower blood pressure. For example, they might dilate or relax the blood vessels to allow blood to flow more freely, reduce excess water and salts from the body, or slow down the heart rate to lower blood pressure. 

Blood pressure medications are available with a prescription only. However, they’re widely accessible as generic drugs that are usually cheaper than brand-name alternatives. The following are some commonly prescribed blood pressure medications by drug class. 

ACE inhibitors

ACE inhibitors are a type of medication that lowers blood pressure by blocking the production of angiotensin II, a hormone that causes blood vessels to constrict. By preventing this constriction, ACE inhibitors help blood vessels to relax and widen, making it easier for blood to flow and ultimately reducing blood pressure.

Zestril, Prinivil (lisinopril)

Lisinopril, sold under the brand names Zestril and Prinivil, is an ACE inhibitor that lowers blood pressure by relaxing blood vessels. Usually taken once a day, the dosage can differ depending on an individual’s needs. Common side effects of this medication include dizziness, dry cough, and headache. 

Vasotec (enalapril)

Enalapril is a medication commonly used to treat high blood pressure and heart failure. It is also used to reduce the risk of heart failure in people with left ventricular dysfunction without any symptoms. It is typically taken once or twice daily, although the standard dosage may vary. Some common side effects of enalapril include headache, dizziness, and dry cough. 


Angiotensin II receptor blockers (ARBs) selectively block the hormone angiotensin II from binding to its receptors, thus blocking its ability to narrow blood vessels. This makes it easier for your blood to flow, reducing stress on your heart and kidneys.

Cozaar (losartan)

Losartan is a medication used to treat high blood pressure and protect the kidneys from damage due to diabetes. It is also used to reduce the risk of stroke in people with high blood pressure and certain heart problems. It is typically taken once daily. While side effects are generally mild, some people may experience dizziness, back pain, or nasal congestion. 

Diovan (valsartan)

Diovan, also known as valsartan, is a medication used to treat high blood pressure and heart failure. It is typically taken once daily with a common dosage ranging from 80 to 320 mg, depending on an individual’s needs. Some side effects specific to this drug include dizziness, headache, and fatigue. 


Diuretics, also known as water pills, are medicines that help your body get rid of extra water and salt through increased urination. They do this by making your kidneys release more sodium, which pulls more water out of your body, lowering fluid build-up and blood pressure.

Microzide (hydrochlorothiazide)

Hydrochlorothiazide is a medication commonly prescribed to help manage high blood pressure. Typically taken once a day, the usual dosage ranges from 12.5 to 50 mg, depending on a person’s treatment goals. Possible side effects may occur, such as dizziness, dehydration, or electrolyte imbalances. 

Lasix (furosemide)

Furosemide is a diuretic medication often prescribed to treat high blood pressure and fluid retention. It is generally taken once or twice a day, with a typical dosage ranging from 20 to 80 mg, depending on the patient’s condition. Potential side effects of furosemide include dizziness, increased urination, and weakness. 

Beta blockers

Beta blockers are a class of medications that work by blocking the effects of stress hormones, such as adrenaline, on the heart and blood vessels. This helps to lower blood pressure, reduce heart rate, and decrease the overall workload on the heart, ultimately improving cardiovascular health.

Lopressor (metoprolol tartrate)

Metoprolol tartrate is a beta blocker medication often used to treat high blood pressure, chest pain, and heart failure. It is typically taken once or twice daily, with 25 to 100 mg dosages. Some common side effects include dizziness, tiredness, and slow heart rate.

Zebeta (bisoprolol)

Bisoprolol is a beta blocker medication commonly prescribed to manage high blood pressure and reduce the risk of heart-related issues. The normal dosage can range from 2.5 to 20 mg once daily. Some potential side effects of bisoprolol include dizziness, slow heart rate, and headache. 

Tenormin (atenolol)

Atenolol is a beta blocker medication prescribed to treat high blood pressure and prevent chest pain caused by angina. It is also approved to reduce the risk of death after a heart attack. It is generally taken once a day, with dosages ranging from 25 to 100 mg per day. Some common side effects of atenolol include dizziness, nausea, and slow heart rate. 

Calcium channel blockers

Calcium channel blockers are a class of medications that block calcium’s movement into the cells of the heart and blood vessels. This action helps to relax and widen blood vessels, which helps lower blood pressure and reduce the workload on the heart.

Norvasc (amlodipine)

Amlodipine is a calcium channel blocker medication commonly used to treat high blood pressure and chest pain. Typically taken once daily, the usual dosage ranges from 2.5 to 10 mg per day. Some potential side effects of amlodipine include dizziness, swelling of the ankles or feet, and flushing.

How do blood pressure medications work?

Blood pressure medications are effective in reducing blood pressure and subsequent complications. The best blood pressure medication will depend on different factors, including treatment goals and other medical conditions. 

A calcium channel blocker or thiazide diuretic is recommended for African American patients for first-line therapy. For people with chronic kidney disease and heart failure, an ACE inhibitor or ARB is typically recommended first. 

Many people with a blood pressure of over 140/90 mmHg may be prescribed a high blood pressure medication, especially if lifestyle changes don’t work. According to the American Heart Association (AHA), one or a combination of high blood pressure medications are used to reach a target blood pressure of less than 140/90 mmHg. People with a blood pressure of 130–139/80–89 mmHg and an increased risk of heart disease may also be prescribed a high blood pressure medication. 

High blood pressure medications are generally more effective with lifestyle changes, including a healthy diet and regular exercise. The DASH diet involves eating more fruits, vegetables, whole grains, and low-fat, lean proteins while reducing salt, unhealthy fats, and added sugars. Combining high blood pressure medications with the DASH diet and regular exercise may help improve blood pressure control and overall heart health.

It’s always a good idea to consult a healthcare provider for the best treatment option if you have high blood pressure.
