          AtenololTopamax
          • 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.
          • Used on its own or with other antiepileptic medicines to lower the frequency of seizures, especially for people with tonic-clonic or partial seizures, or Lennox-Gestaut syndrome.
          • Helpful in preventing frequent migraine headaches.
          • Doesn't need routine blood tests.
          Downsides and risks
          AtenololTopamax
          • You have to take Atenolol on an empty stomach.
          • 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.
          • Not a first-choice treatment for high blood pressure according to the latest guidelines, except if you have heart failure or heart disease. As a second choice, your doctor might add it to medicines you're already taking if your blood pressure is still too high.

          • Can hide symptoms of low blood sugar if you're diabetic.
          • Can cause sleepiness, speech problems, tingling sensations, and weight loss.
          • A few people will get kidney stones.
          • Not safe to use if you're pregnant.
