What is Hyzaar “50/12.5/5 mg”?
Hyzaar is the brand name for a fixed-dose combination tablet of losartan (an angiotensin II receptor blocker, ARB) plus hydrochlorothiazide (a thiazide diuretic). The common Hyzaar strengths are written like 50/12.5 mg (losartan/hydrochlorothiazide).
If you are seeing “50 12 5 mg” written without slashes, that typically corresponds to Hyzaar 50 mg / hydrochlorothiazide 12.5 mg.
Is “50/12.5/5 mg” a standard Hyzaar strength?
A single Hyzaar tablet is designed to contain two active ingredients (losartan + hydrochlorothiazide), not three. So a notation like “50/12.5/5 mg” is unusual for Hyzaar and may reflect:
- a transcription or formatting error (for example, mixing it with another product strength), or
- confusion with a different medication that includes a “5 mg” component.
If you can share the exact wording from the label (including whether it says “losartan potassium/hydrochlorothiazide”), I can help verify what the “5 mg” refers to.
What conditions is Hyzaar used to treat?
Hyzaar is used for:
- High blood pressure (hypertension), and
- in some patients, to help reduce risk of stroke when used for appropriate cardiovascular risk profiles (per prescribing information).
How should it generally be taken?
Hyzaar is usually taken once daily, and the hydrochlorothiazide component can affect electrolytes and fluids. Patients are often advised to follow the prescriber’s directions and have periodic blood tests (for kidney function and electrolytes), especially when starting or changing dose.
What side effects and safety issues do people ask about?
Common issues associated with losartan + hydrochlorothiazide include:
- dizziness or lightheadedness (blood pressure changes),
- electrolyte changes (such as low potassium or low sodium),
- dehydration or increased urination,
- kidney function changes.
A key warning with losartan-containing medicines: they are not used in pregnancy, because ARBs can cause harm to a fetus.
Could there be a different medication you actually meant?
Hyzaar is typically only losartan + hydrochlorothiazide. If the “5 mg” is accurate, it might be from another drug taken together (for example, a potassium supplement, another blood pressure medicine, or a different condition drug), not part of Hyzaar itself.
If you post a photo or type the label exactly (drug name and strength line), I can tell you what medication you have and how that strength maps to the active ingredients.
