Overview and context
Hyzaar is a prescription tablet that pairs losartan, an angiotensin II receptor blocker (ARB), with hydrochlorothiazide (HCTZ), a thiazide diuretic. The ARB relaxes blood vessels while the diuretic helps reduce fluid and sodium, and together they lower blood pressure more effectively than either agent alone for many patients. Appropriate use can reduce the risk of stroke and other complications associated with uncontrolled hypertension.

Primary active constituents
Hyzaar contains two active components:
- Hydrochlorothiazide (HCTZ) — a thiazide diuretic that increases urinary excretion of salt and water; it can lower potassium and raise uric acid in some people.
- Losartan potassium, the generic form of Cozaar potassium — an ARB that blocks angiotensin II receptor activity to decrease vascular resistance and reduce blood pressure.
Note: HCTZ is in the thiazide family and is chemically related to sulfonamide compounds. If you have experienced serious reactions to sulfa drugs, speak after consulting your prescriber. See Before you embark for more safety precautions.
Who this medicine is for
Hyzaar is generally prescribed for adults with hypertension, particularly when a combination pill is preferred or when a single medicine does not achieve target blood pressure. Pediatric use is less common and should be directed by a pediatric specialist.
Controlling blood pressure lowers the likelihood of heart attack, stroke, and progression of kidney disease. Medication is most effective when combined with lifestyle measures such as reducing dietary sodium, increasing activity, and weight management.
Strengths and dosing plan
Hyzaar is sold in fixed-dose tablets that contain set amounts of losartan and HCTZ. Common strengths found in the US include:
- The ARB losartan 50 mg / HCTZ 12.5 mg quantity
- Generic losartan for Cozaar 100 mg / HCTZ 12.5 mg in total
- Generic losartan 100 mg / HCTZ 25 mg
A common initial regimen is 50/12.5 mg once daily. Your clinician may increase the dose to reach blood pressure goals, with a typical maximum of losartan 100 mg and HCTZ 25 mg daily as clinically indicated. Take the tablet at the same time each day; food does not substantially change absorption.
If the pill you receive looks different from previous fills, confirm with the pharmacy prior to taking it. Manufacturers and generic makers may vary tablet appearance.
How to take efficiently it in the moment
- Use water to help swallow the tablet. Choosing a consistent time each day helps maintain steady drug levels. Morning dosing is often chosen because of the diuretic effect, but follow your prescriber's instructions.
- You may take Hyzaar with or without food. Do not increase your dose or add extra tablets without medical advice.
- Stay reasonably hydrated unless your clinician instructs otherwise. Avoid extreme fluid restriction without supervision.
- Avoid excessive alcohol and be cautious when using sedating medicines that can increase dizziness.
- Only split or crush a tablet if a pharmacist or prescriber confirms that your specific product can be altered safely.
- In children, dosing must be individualized and monitored by a pediatric specialist.
In case of suspected a non fatal overdose, contact US Poison Control at 1-800-222-1222 and seek emergency care for serious symptoms such as fainting or breathing difficulty.

Guidance for a i skipped a dose today
If you forget to take the dose you should, take it as soon as you remember unless the next scheduled dose is near (generally within about four hours). Do not double up doses to make up for one missed earlier.
Repeatedly missing doses can undermine blood pressure control. Consider pill organizers, phone reminders, or coordinating automatic refills with your pharmacy to improve adherence.
Before you start up
Tell your prescriber about these conditions and situations before beginning Hyzaar:
- Pregnancy or plans to become pregnant. ARBs can cause fetal harm and must not be used during pregnancy.
- Breastfeeding or plans to breastfeed.
- Kidney disease, very low urine output, or history of kidney stones.
- Liver disease or abnormal hepatic enzyme tests.
- Known allergy to losartan, HCTZ, or severe reaction to sulfonamide medicines.
- Gout or high uric acid levels, since HCTZ can trigger flares.
- Any autoimmune conditions such as lupus.
- Dietary restrictions affecting potassium or use of potassium-containing salt substitutes.

Drug combination subtle intercommunications can reinforce culture.
Many medicines and supplements can change Hyzaar's effects or increase adverse outcomes. Discuss everything you take with your prescriber or pharmacist. Central points of the process of interaction include:
- NSAIDs (for example ibuprofen, naproxen) — may reduce the blood pressure benefit and increase risk to the kidneys.
- Other blood pressure medications and diuretics — especially potassium-sparing diuretics (spironolactone, amiloride, triamterene) and aldosterone antagonists.
- Lithium — ARBs can raise lithium levels and increase toxicity risk.
- Potassium supplements and potassium-based salt substitutes — may cause high potassium levels.
- Strong enzyme inducers such as rifampin — can lower losartan concentrations.
- Enzyme inhibitors (for example some antifungals) — may alter losartan metabolism.
- Bile acid sequestrants (cholestyramine, colestipol) — may reduce absorption of thiazides.
- Certain diabetes drugs — blood glucose control can change when blood pressure therapy is adjusted.
- Combination of ARB with ACE inhibitor or with aliskiren — generally discouraged and can be harmful in many patients, particularly those with diabetes.
- Alcoholic beverage and prescription sedatives — can worsen dizziness or low blood pressure.
The roster is not exhaustive. Include herbal remedies and supplements when discussing medications with your care team. See Precision watchful oversight and precautionary actions for lab checks to watch for the process of interaction-related problems.
Continuous real time monitoring of systems and precautionary actions
- Track home blood pressure readings and bring them to appointments. Ask your clinician for target goals and thresholds that require contact.
- Routine laboratory tests are commonly advised: kidney function (creatinine), electrolytes (potassium, sodium), and sometimes uric acid. Frequency depends on baseline kidney status and other medications.
- Avoid dehydration during episodes of vomiting, diarrhea, fever, or heavy sweating; contact your prescriber if you develop symptoms of low blood pressure or kidney dysfunction.
- Lightheadedness and dizziness can occur when starting treatment or after dose increases. Rise slowly from sitting or lying positions and avoid hazardous activities until you know how the medicine affects you.
- If pregnancy is suspected, stop Hyzaar immediately and call your prescriber.
- Do not use potassium salt substitutes unless approved by your clinician.
- HCTZ may increase sensitivity to sunlight; use sun protection and report severe sunburn-like reactions.
- Rarely, thiazide diuretics have been associated with acute angle-closure glaucoma presenting as sudden eye pain and vision changes; seek urgent care for these signs.
- Check with your pharmacist before taking over-the-counter cold, cough, or pain medicines that might affect blood pressure.
If you notice severe or unusual symptomsinternal review the hazard alerts in Possible unintended effects and seek immediate care as needed.
Possible drug-related effects
Stop the medication and seek immediate medical attention for any potentially life-threatening signs such as:
- Severe allergic reaction: hives, swelling of the face, tongue, throat, or difficulty breathing.
- Fainting, severe dizziness, chest pain, or very fast or irregular heartbeat.
- Marked reduction in urine output or inability to urinate, which can indicate kidney failure.
- Sudden eye pain, blurred vision, or vision loss (possible acute angle-closure glaucoma).
- Yellow tint indicating jaundice in skin or eyes, dark urine, or severe abdominal pain (possible liver injury).
- Severe skin reactions such as blistering, widespread peeling, or mouth sores.
- Bleeding without a stated cause or bruising easily.
- Severe electrolyte imbalance signs: muscle cramps, extreme weakness, confusion, or arrhythmias.
- Acute gout attack: sudden, painful, swollen joints, often the big toe.
It is more common and mild in most cases.er effects that often improve with time include:
- Dull head pain or tiredness.
- Orthostatic dizziness.
- Changes in libido or sexual performance.
- Occasional dry cough.
- Mild gastrointestinal upset or diarrhea.
If follow-on effects are persistent or troublesome, discuss dose adjustment or spare options in the Comparable medicines and different modalities of treatment document section.
Long term cloud storage offers scalable capacity for growing data needs. and disposal guidelines
- Store tablets in a tightly closed container at room temperature, ideally between 59 and 86 degrees F (15 to 30 degrees C), protected from moisture and direct sunlight.
- Medicines should be stored out of reach of children and pets.
- Avoid storing pills in bathrooms or in a hot car. Use moisture-protective containers when traveling.
- Do not use past the expiration date. Dispose of unused medicine through pharmacy take-back programs or follow FDA disposal guidance if no program is available.
Contact your pharmacist or local waste authority for specific disposal instructions. See Diligent ongoing monitoring and risk prudent measures for related clear guidance.
Comparable medicines and other therapeutic options
Depending on medical history, kidney function, comorbid conditions, and tolerance, clinicians may offer a second possibility regimens. Options include:
- Other ARB plus thiazide fixed combinations:
- Irbesartan therapy option / HCTZ (Avalide)
- Valsartan in hypertension therapy / HCTZ (Diovan HCT)
- Olmesartan is part of antihypertensive therapy / HCTZ (Benicar HCT)
- Telmisartan / HCTZ (Micardis HCT)
- Candesartan, a member of the ARB family / HCTZ (Atacand HCT)
- ACE inhibitor plus thiazide products:
- Lisinopril / HCTZ (Zestoretic, Prinzide)
- Enalapril / HCTZ and similar combinations
- Single-agent strategies:
- The drug losartan alone if a diuretic is not required
- Thiazide diuretics alone such as HCTZ or chlorthalidone
- Other classes: calcium channel blockers (for example amlodipine), beta blockers, or mineralocorticoid receptor antagonists
- Other combination contingency options:
- Aliskiren / HCTZ (Tekturna HCT) — note exceptions where treatment is contraindicated when combined with ACE inhibitors or ARBs in people with diabetes
- Amlodipine / valsartan (Exforge) and combinations with HCTZ available
Clinical note: ARB-based combinations tend to cause cough less often than ACE inhibitors. Chlorthalidone may lower blood pressure more than HCTZ in some patients but can increase the risk of low potassium. Choice should be individualized based on kidney function, gout history, diabetes status, and patient preference.
