Looking for an olmesartan-medoxomil-hctz coupon? This medication is the generic version of Benicar HCT, a fixed-dose combination of olmesartan medoxomil (an angiotensin II receptor blocker, or ARB) and hydrochlorothiazide (a thiazide diuretic) used to treat high blood pressure. Because it is available as a generic, the cash price is already relatively low, but what you actually pay can vary widely from one pharmacy to the next. Enter your ZIP above to compare today's price across more than 60,000 U.S. pharmacies and find a discount coupon you can use at the counter, even without insurance.
What is olmesartan-hydrochlorothiazide and how does it work?
Olmesartan medoxomil / hydrochlorothiazide is a combination blood pressure medication. Olmesartan is an angiotensin II receptor blocker (ARB) that relaxes blood vessels so blood can flow more easily, while hydrochlorothiazide is a thiazide diuretic ("water pill") that helps your body remove extra salt and fluid. Together they lower blood pressure and, over time, help reduce the risk of cardiovascular events such as stroke and heart attack.
This combination is FDA-approved for high blood pressure (hypertension), but it is not used as a first, or starting, treatment. Doctors typically prescribe it when blood pressure is not well controlled on olmesartan or hydrochlorothiazide alone, or as a convenient single pill for patients already taking both components separately. This is general information, not medical advice; your provider decides whether this medicine is right for you.
How much does generic olmesartan-hydrochlorothiazide cost, and how to save
Olmesartan-hydrochlorothiazide is available as a generic, which is the main reason it usually costs far less than the brand-name version, Benicar HCT. Even so, cash prices are not the same everywhere. The price for the exact same pills and strength can differ significantly between two pharmacies in the same town, so comparing before you fill is the single best way to keep your out-of-pocket cost down.
Rx.com compares live prices across more than 60,000 pharmacies so you can see where this medication is cheapest near you. Enter your ZIP above to see today's price and pull up a free discount coupon you can show at the pharmacy, no insurance required. If you have insurance, it is still worth comparing, because a coupon price is sometimes lower than a copay.
Related medications and alternatives
If you are comparing options, it can help to look at both the brand equivalent and other ARB-plus-diuretic combinations. The brand-name version of this exact medicine is Benicar HCT. Other closely related choices include:
- Olmesartan medoxomil — the ARB component on its own, without the diuretic.
- Hydrochlorothiazide — the thiazide diuretic on its own.
- Losartan-hydrochlorothiazide — a different ARB combined with the same diuretic.
- Valsartan-hydrochlorothiazide — another ARB-plus-diuretic combination.
Only your prescriber can decide which medication and dose fit your situation. Use the price tools above to compare the cash price of each option side by side.
Safety information you should know
This medicine carries a boxed warning for fetal toxicity: drugs that act on the renin-angiotensin system can cause serious injury or death to an unborn baby. It should not be used during pregnancy, and it should be stopped as soon as pregnancy is detected. Talk to your provider right away if you are pregnant or planning to become pregnant.
Other risks to be aware of include low blood pressure (especially if you are dehydrated or on a low-salt diet), high potassium, and reduced kidney function, particularly if combined with NSAID pain relievers or other blood-pressure drugs that act on the same system. The hydrochlorothiazide portion can cause electrolyte imbalances (such as low potassium, low sodium, or low magnesium), raised uric acid or gout, higher blood sugar, sun sensitivity, and, rarely, sudden vision changes or eye pressure problems; it may also increase the risk of non-melanoma skin cancer. A rare but serious side effect linked to olmesartan is a severe, sprue-like intestinal problem causing chronic diarrhea and weight loss. This is not a complete list. Tell your doctor about all the medicines you take, and contact your provider or pharmacist with any questions or concerning symptoms.
