      Upsides and benefits
      AtenololBystolic
      • A first-choice treatment to prevent chest pain (angina).
      • A first-choice treatment for heart failure and heart attack.
      • At lower doses, Atenolol has fewer side effects than most beta blockers because it targets the heart and doesn't cross into the brain and central nervous system.
      • Controls your heart rate to reduce work for your heart.
      • A first-line treatment for heart failure and heart attack.
      • Helps to lower blood pressure if you can't use first-choice treatments or need additional blood pressure control.
      • Many beta blockers can worsen asthma or cause headaches, but Bystolic usually doesn't because it targets the heart more specifically and causes fewer side effects.
      Downsides and risks
      AtenololBystolic
      • You have to take Atenolol on an empty stomach.

      • You can't miss doses. Stopping Atenolol suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.
      • Taking a beta blocker might make you feel more tired or out of breath during exercise or normal daily routines. This gets better for most people, but for some might not go away.
      • Can hide symptoms of low blood sugar if you're diabetic.
      • Not available in less expensive generic form.
