(HealthDay News) — Beta blockers often are prescribed to treat various heart conditions, including congestive heart failure and an irregular heartbeat. They also may be used to help treat high blood pressure.
As with any drug, beta blockers may cause side effects in some people. The American Academy of Family Physicians says although most people have no side effects from beta blockers, it offers this list of possible adverse reactions:
- Fatigue or lack of energy.
- Decreased libido or impaired sexual function in men.
- Dizziness or lightheadedness.
If you have serious side effects from one of these medicines — including difficulty breathing, chest pain, slowed heart rate of fewer than 50 beats per minute, unexplained weight gain or swelling of the hands, legs or feet — contact your doctor immediately.
