Hyzaar (generic name: losartan + hydrochlorothiazide) is an oral medication that can be prescribed to treat high blood pressure (hypertension) and to reduce the risk of stroke and heart attacks in people with hypertension. The brand Hyzaar is sold under the brand name Oscaar Plus outside of the U.S. It is manufactured in the Netherlands by the license owner MSD. Losartan is a member of a group of drugs called angiotensin II receptor antagonists (ARB). It keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent the body from absorbing too much salt, which can cause fluid retention.

  • Why is hydrochlorothiazide prescribed with losartan?
    Hyzaar combines hydrochlorothiazide and losartan and is used to treat hypertension. Losartan lowers the blood pressure by relaxing blood vessels. Hydrochlorothiazide is a thiazide diuretic that can reduce the amount of water in the body by increasing the extraction of fluids from the blood by the kidneys. This also helps to lower blood pressure.
  • What foods should you avoid when taking losartan?
    Losartan can cause significant increases in the levels of potassium in the blood. However, hydrochlorothiazide may have the opposite effect of lowering potassium levels and some guides advise to eat foods that are high in potassium such as oranges or bananas to prevent potassium loss . Check with a doctor.
  • Can I drink a glass of wine while taking hydrochlorothiazide?
    It's advisable to avoid or minimize alcohol intake while taking hydrochlorothiazide(HCTZ.) As well as lowering blood pressure, HCTZ can cause electrolyte imbalances through dehydration, and dizziness. Ask a healthcare provider what is a safe amount of alcohol to drink.
  • Why no sunlight when taking hydrochlorothiazide?
    Exposure to sunlight, even if the exposure is brief, can lead to skin rashes, severe sunburn, skin irritation, itching, discoloration, and even changes in vision. When first taking Hyzaar it's advisable to stay out of direct sunlight, especially between 10:00 am and 3:00 pm, or to wear a strong sunscreen plus a hat and to cover arms and shoulders if avoiding the sun is not possible.
