What is losartan potassium and how does it work?

Losartan potassium is an angiotensin II receptor blocker (ARB). It works by blocking a natural substance in the body that tightens blood vessels, which helps blood vessels relax and lowers blood pressure. It is available as a generic and is sold under the brand name Cozaar.

Losartan is FDA-approved to treat high blood pressure (hypertension), either on its own or with other medicines; to lower the risk of stroke in people who have high blood pressure along with left ventricular hypertrophy (a thickening of the heart's main pumping chamber); and to treat diabetic nephropathy (kidney disease) in people with type 2 diabetes and high blood pressure. Note that in patients who are Black or African American, losartan may not reduce stroke risk. Your prescriber decides whether losartan is right for your situation.

Losartan potassium cost and how to save without insurance

Because losartan is a generic, it is generally one of the more affordable blood pressure medications, even for people paying cash without insurance. That said, the price you actually pay is not the same everywhere. Different pharmacies set different cash prices for the exact same prescription, and the gap between the highest and lowest price can be surprisingly large. That is why comparing pharmacies is worth a few seconds of your time.

Losartan alternatives and related medications

Losartan belongs to the ARB family, and there are several related medicines your prescriber might consider. Other ARBs include valsartan, olmesartan, irbesartan, and telmisartan. A closely related class, ACE inhibitors, includes lisinopril.

Losartan is also available combined with a water pill as losartan-hydrochlorothiazide for people who need added blood pressure control. The brand-name version of losartan alone is Cozaar. Only your prescriber can decide whether switching or combining medications is appropriate for you, but you can compare prices on each option here.

Safety information and side effects

Boxed warning — pregnancy: Losartan can cause serious harm or death to a developing baby. If you become pregnant or think you might be pregnant, stop taking losartan and contact your prescriber right away. Medicines that act on the renin-angiotensin system should not be used during pregnancy.

Losartan can raise potassium levels (hyperkalemia), lower blood pressure too much (especially if you are dehydrated or on a low-salt diet or water pills), and affect kidney function. Use caution when combining it with ACE inhibitors, potassium-sparing water pills, or potassium supplements, and avoid using it with aliskiren if you have diabetes. There is also a rare risk of angioedema (serious swelling). Common side effects include dizziness, upper respiratory infection, nasal congestion, and back pain. This is not medical advice — talk with your doctor or pharmacist about your full medication list and any conditions before starting or changing losartan.
