Beta blocker drugs and other treatment options
Beta-blocker drugs
A beta-blocker such as bisoprolol or carvedilol is usually prescribed in addition to an ACE inhibitor. Like ACE inhibitors, beta-blockers have a protective effect on the heart. A low dose is started at first, and then increased every few weeks until a regular dose is reached. Occasionally, beta-blockers cause an initial worsening of symptoms before the symptoms improve.
Research studies have shown that ACE inhibitors and beta-blockers not only help to ease symptoms, but can improve the outlook and extend life expectancy for people with heart failure. Therefore, even if symptoms go, continue to take these drugs if they are prescribed.
Diuretics ('water tablets')
A diuretic is commonly needed to ease fluid retention. This is taken in addition to an ACE inhibitor and beta-blocker. Diuretics work on the kidneys and make you pass out extra urine. This helps to clear excess body fluid that builds up. There are different types and brands of diuretics. The dose depends on how bad the fluid retention has become, and can be increased if necessary if fluid retention becomes worse.
Diuretic tablets are normally taken in the morning. This is so the extra toilet trips are during the day, and not at night. (Their effect on making extra urine lasts about six hours.) However, they can be taken at other times. For example, if you plan a morning shopping trip, take the diuretic tablet when you return.
Other drugs
Spironolactone and/or digoxin may be advised in addition to the drugs described above if your condition becomes worse. Spironolactone works to help clear the body of excess fluid. Digoxin works by helping the heart muscle to contract more strongly. (It also has another action to regulate the heart rate if you also have an arrhythmia called atrial fibrillation.)
