Key takeaways:
The treatment options for high blood pressure include low-cost generics and combination pills. This helps to make medications affordable and more convenient to take.
Medications to treat high blood pressure differ in how they work and who’s best suited to take them.
A healthcare professional will consider your age, history, and other factors when picking the best blood pressure medication for you.
Here are the names of blood pressure medications that are low-cost generics, sorted by their class.

There are four types of blood pressure medications that are commonly used first:
Thiazide diuretics
Calcium channel blockers
ACE inhibitors
Angiotensin II receptor blockers (ARBs)
They work in different ways to lower blood pressure. Sometimes you may need more than one.
Let’s take a look at the different types of first-choice blood pressure medications.
Type of Medication | How they work | Who they’re good for | Side effects | Examples | Common first choice? |
---|---|---|---|---|---|
Thiazide diuretics | Increase urination to get rid of extra water and sodium (salt), which reduces stress on the blood vessels | Most people | Low sodium or potassium levels | Chlorthalidone (Thalitone) Hydrochlorothiazide (HCTZ) | Yes |
Calcium channel blockers | Block calcium at the heart, which slows the heart rate and relaxes the blood vessels | Most people | Amlodipine (Norvasc) Diltiazem (Cardizem) | Yes | |
ACE inhibitors | Stop the body from making angiotensin II — relaxing blood vessels and reducing fluid retention | Most people, but they’re especially good options for people with kidney disease | High potassium Dry cough Angioedema (severe swelling of the face and mouth). | Benazepril (Lotensin) Lisinopril (Zestril) | Yes |
Angiotensin II receptor blockers (ARBs) | Block angiotensin II from attaching to its receptors — relaxing blood vessels and reducing fluid retention | Especially good options for people with kidney disease | Dizziness Low blood pressure | (Cozaar) (Diovan) | Yes |
There are several other types of medications that may be used to lower blood pressure. These are typically prescribed when your blood pressure is still high after trying the first-choice options mentioned above. They might be used if you have other health conditions that these medications can help to treat.
Let’s run through some of those choices.
Type of Medication | How they work | Who they’re good for | Side effects | Examples | Common first choice? |
---|---|---|---|---|---|
Beta blockers | Slow the heart rate — relieving stress on blood vessels | Helpful for those with coronary artery disease or who are pregnant | Dizziness Tiredness Constipation | Atenolol (Tenormin) Propranolol (Inderal) | Sometimes, especially during pregnancy |
Alpha blockers | Relax the blood vessels so blood can flow more freely | Useful for some men with high blood pressure who also have an enlarged prostate | Lightheaded when standing up quickly | Doxazosin (Cardura) Prazosin (Minipress) | Sometimes |
Alpha / beta blocker combination pills | Act in the same way as single alpha and beta blockers | People whose blood pressure fluctuates significantly | Same as alpha and beta blockers | Carvedilol (Coreg) | Not usually |
Loop diuretics | Increase urination to get rid of excess fluid from the body | People who have extra fluid caused by heart failure or kidney disease | Low sodium or potassium levels | Furosemide (Lasix) | Sometimes |
Potassium- sparing diuretics | Increase urination to get rid of excess fluid from the body | People with heart failure or liver disease | Low sodium levels | Amiloride (Midamor) Triamterene (Dyrenium) | No |
Aldosterone antagonists | Increase urination to get rid of excess fluid from the body | Some people with heart failure | Breast tenderness (males and females) Loss of libido (in males) | Eplerenone (Inspra) Spironolactone (Aldactone) | Not usually |
Several other types of medications are less commonly used to lower blood pressure. They work by relaxing blood vessels. These medications typically have more side effects or interact with lots of other medications.
Examples include:
Vasodilators, like hydralazine and minoxidil
Alpha-2 receptor agonists and central agonists, like clonidine (Catapres), methyldopa, and guanfacine
Direct renin inhibitors, like aliskiren (Tekturna)
Two or more blood pressure medications are sometimes combined into a single pill. These combination products make it easier to take multiple blood pressure medications at once.
The drawback? This can make it harder to adjust the dose of either medication by itself.
Examples of popular combination blood pressure medications are:
Diovan HCT (valsartan / hydrochlorothiazide)
Maxzide (hydrochlorothiazide / triamterene)
Lotensin HCT (benazepril / hydrochlorothiazide)
Hyzaar (losartan / hydrochlorothiazide)
Lotrel (amlodipine / benazepril)
Zestoretic (lisinopril / hydrochlorothiazide)
Generic blood pressure medications may differ in shape, color, and size. But they work just as well as brand-name medications. Generic and brand-name blood pressure medications that contain the same ingredient are bioequivalent. This means they work exactly the same in terms of the dose, strength, and performance in the body.
Low-dose thiazide diuretics are found to most effectively reduce blood pressure and its complications — like heart attack, stroke, and death — with few side effects. They’re a good first-choice medication for many people when they’re first diagnosed with hypertension. The best choice for you will depend on many factors like your medical history and current medications.
Staying hydrated is important for your overall health. Drinking water may help reduce the risk of high blood pressure. But there isn’t strong evidence that drinking water can lower blood pressure that’s already high. In fact, in some cases drinking too much water can lead to more complications and may even increase your blood pressure.
Talk to a healthcare professional if you’re considering increasing your water intake in an attempt to lower your blood pressure.
There are many options when it comes to blood pressure medications. A healthcare professional will decide what’s best for you based on a number of factors. These include your age, medical history, and other medications you may be taking. Cost may also be a factor.
Fortunately, many blood pressure medications have low-cost generic options available. Talk to your prescriber about all of your treatment options.
