      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.
