3.7/ 5 average rating with 464 reviewsforLopressor
Lowers blood pressure. Removes extra water from your body.

Hyzaar (Losartan / Hydrochlorothiazide) is a good combination blood pressure-lowering medicine to try if your blood pressure is very high.

Upsides
  • A first-choice treatment to prevent chest pain (angina).
  • Makes pain episodes less frequent and makes it easier to be active without having chest pain.
  • A first-choice treatment for people who've had a heart attack.
  • Lopressor (metoprolol tartrate) lowers the risk of death during and after a heart attack.
  • Lopressor (metoprolol tartrate) is cheaper than the extended release version.
  • Lowers the risk of heart attack and stroke.
  • A first-choice treatment for severe high blood pressure, combining the benefits of two blood pressure-lowering medicines with a single pill.
  • Protects kidney function, which is especially useful for people with diabetes or mild-to-moderate kidney disease.
  • Helpful in getting rid of extra fluids if you have issues with fluid balance (like in congestive heart failure).
  • Most people have few side effects.
Downsides
  • You need to take Lopressor (metoprolol tartrate) with food twice a day for it to work best.
