Question 1

What is Hyzaar?

Accepted Answer

Hyzaar is a combination medicine that contains losartan and hydrochlorothiazide. Losartan is an angiotensin II receptor antagonist that works by blocking a substance in the body that causes blood vessels to tighten, which helps the blood flow more smoothly. Hydrochlorothiazide is a diuretic, or water pill, that helps the kidneys remove extra water and salt from the body through urine.

By combining these two medications, Hyzaar addresses blood pressure management through multiple pathways. This dual-action approach helps to relax the blood vessels and reduce the overall fluid volume in the circulatory system.

Question 2

What is Hyzaar used for?

Accepted Answer

Hyzaar is used to treat hypertension and to reduce the risk of stroke in patients with hypertension who have left ventricular hypertrophy .

Question 3

How does Hyzaar work?

Accepted Answer

Hyzaar contains two active ingredients, losartan and hydrochlorothiazide, which use different mechanisms to manage high blood pressure.

Relaxing Blood Vessels

Losartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs). It works by blocking the action of a natural substance in the body that causes blood vessels to tighten or narrow. When this substance is blocked, the blood vessels relax and widen, which allows blood to flow more easily and lowers blood pressure.

Reducing Fluid Volume

Hydrochlorothiazide is a diuretic, often called a water pill. It works by prompting the kidneys to remove extra salt and water from the body through urine. This process reduces the total volume of fluid circulating in the bloodstream, which decreases the pressure against the walls of the blood vessels.

Combined Effect

By combining these two medications, Hyzaar addresses blood pressure in two ways simultaneously:

Vessel relaxation: Losartan prevents the physical narrowing of the arteries.

Fluid management: Hydrochlorothiazide reduces the amount of fluid the heart must pump.

Working together, these mechanisms help keep blood pressure within a healthier range, which reduces the long-term risk of stroke, heart attack, and kidney damage.

Question 4

The active ingredients in Hyzaar are losartan and hydrochlorothiazide .

Question 5

What are the side effects of Hyzaar?

Accepted Answer

Common side effects of Hyzaar may include:

dizziness

upper respiratory infection

fatigue

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Hyzaar?

Accepted Answer

Hyzaar belongs to the angiotensin II receptor blocker and thiazide diuretic combination drug class.

Question 7

What is the dosage of Hyzaar and how do I take it?

Accepted Answer

How to Take

Hyzaar is taken by mouth, typically once a day. It can be taken with or without food. For the best results, take this medication at the same time every day to help you remember and to keep a steady amount of the drug in your body.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is nearly time for your next dose, skip the missed dose and resume your regular schedule. Do not take two doses at once to make up for a missed one.

Storage

Store this medication at room temperature, away from moisture and heat. Keep the container tightly closed when not in use and keep it out of reach of children.

Question 8

Is Hyzaar safe during pregnancy and breastfeeding?

Accepted Answer

Hyzaar should not be used during pregnancy. Taking this medication during the second and third trimesters can cause serious injury or even death to the developing fetus. This is primarily due to the losartan component, which can affect the baby's kidney function and lead to complications such as low amniotic fluid levels, lung underdevelopment, and skeletal deformities.

If you become pregnant while taking Hyzaar, you should contact your healthcare provider immediately and stop taking the medication as directed. Women of childbearing age should discuss effective birth control options and the risks of this medication with their doctor before starting treatment.

It is not fully known if losartan passes into human breast milk, though it has been found in the milk of laboratory animals. The other component, hydrochlorothiazide, is known to pass into breast milk and may decrease the amount of milk produced.

Because of the potential for serious side effects in a nursing infant, a decision must be made whether to stop breastfeeding or stop taking the medication. Patients should discuss their specific situation and potential alternatives with a healthcare professional to determine the safest course of action.

Question 9

What forms and strengths does Hyzaar come in?

Accepted Answer

Oral tablet

Question 10

What is the FDA approval status of Hyzaar?

Accepted Answer

FDA Approval and Indications

Hyzaar, a combination of the angiotensin II receptor antagonist losartan potassium and the thiazide diuretic hydrochlorothiazide, is approved by the U.S. Food and Drug Administration (FDA) for two primary uses:

The treatment of hypertension (high blood pressure) to lower blood pressure.

To reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy (an enlargement of the walls of the left side of the heart).

The FDA notes that there is evidence suggesting this stroke-reduction benefit may not apply to Black patients.

Boxed Warning: Fetal Toxicity

The FDA requires a boxed warning for Hyzaar because the medication can cause serious injury or death to a developing fetus. Drugs that act directly on the renin-angiotensin system, such as the losartan component of Hyzaar, should be discontinued as soon as pregnancy is detected.

Safety Communications and Contraindications

The FDA has issued safety communications regarding the use of medications like Hyzaar in combination with other blood pressure drugs. Specifically, the use of Hyzaar is contraindicated (should not be used) in combination with aliskiren in patients with diabetes or renal impairment. This combination increases the risk of low blood pressure (hypotension), high potassium levels (hyperkalemia), and changes in kidney function.

Hyzaar is also contraindicated in patients with anuria (the inability to produce urine) or a known hypersensitivity to any component of the drug or other sulfonamide-derived drugs.

Generic Availability

Hyzaar was originally approved as a brand-name medication, but the FDA has since approved multiple generic versions of losartan potassium and hydrochlorothiazide. Generic formulations are required to meet the same standards for safety, strength, and quality as the brand-name product.

Question 11

What should I know about Hyzaar and cost?

Accepted Answer

Generic Availability

Hyzaar is available as a generic medication known as losartan and hydrochlorothiazide. Generic versions contain the same active ingredients as the brand-name drug but are typically sold at a lower price point.

Insurance and Coverage

Most prescription insurance plans, including Medicare Part D, provide coverage for the generic form of this medication. Brand-name Hyzaar may be subject to higher out-of-pocket costs or may require prior authorization from an insurance provider.

Pricing Factors

The final price of the medication can be influenced by:

Pharmacy Selection: Prices often vary between different retail pharmacies and mail-order programs.

Prescription Size: Purchasing a 90-day supply may offer a lower cost per pill compared to a 30-day supply.

Discount Programs: Pharmacy discount cards or manufacturer assistance programs may be available to help reduce costs for eligible patients.
