High & Low Blood Pressure board

It depends on your type of a heart problem, other medical conditions and the medications you are currently on.

As a matter of fact, diuretics are used in treatment of heart disease. They help control blood pressure by causing elimination of excess fluid. This makes it easier for the heart to pump.
When treating heart failure, thiazides are appropriate for long-term use to reduce fluid build-up in the lungs. Because they are so powerful, loop diuretics are used mostly short-term for immediate results; long-term only for more severe forms of HF. Potassium-sparing diuretics are usually prescribed in addition to both.

Thiazide type diuretics may cause high cholesterol or triglycerides in people with heart or blood vessel disease. Also, the use of some heart medications, such as Digitalis, with thiazide diuretics may cause high blood levels of lithium, which then leads to other undesirable effects.
If the Hctz is co-administered with metoprolol, as is commonly done, there is a chance of a moderate interaction between the two drugs. There is a possibility of an increase in cholesterol, triglyceride and blood sugar levels. A potassium-depleting diuretic can worsen certain types of arrhythmia. Serum potassium, blood glucose and of course, blood pressure should be monitored when these two drugs are taken together. Consult your doctor - if you need a further blood pressure reduction, you might be able to do it with the addition of hctz.

good luck,
