Compare Atenolol vs. Tenex
Head-to-head comparisons of medication uses, side effects, ratings, and more.
Tenormin (atenolol) is good for controlling chest pain and treating a heart attack. It has fewer side effects than other beta blockers. You need to take it on an empty stomach and you can't skip doses.
Tenex (Guanfacine) can be used to treat both blood pressure and ADHD, but it's not recommended as a first-line treatment for either problem.
- A first-choice treatment to prevent chest pain (angina).
- A first-choice treatment for heart attack recovery.
- At lower doses, Tenormin (atenolol) has fewer side effects than other beta blockers because it targets the heart and not other parts of the body.
- The same medication treats two different things, high blood pressure and attention deficit hyperactivity disorder (ADHD).
- It's not a "controlled medication".
- Used to control ADHD when stimulant medications haven't worked or can't be used due to other medical problems.
- Available as a generic medication, so it should be more affordable than other options.
- You need to take Tenormin (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 it might not go away for others.
- Not a first-choice treatment for high blood pressure unless you have heart disease. However, your doctor could add it to other medicines you're already if your blood pressure is still too high.
- You can't miss or skip doses. If you stop Tenormin (atenolol) suddenly, it can cause your blood pressure to go up really quickly, raising your risk of heart attack and stroke.
- Tenormin (atenolol) can hide symptoms of low blood sugar if you're diabetic.
- Doesn't control ADHD as well as stimulants do, so it's used as a second-line medication.
- Not a preferred drug to control blood pressure.
- Can't be stopped suddenly, especially for blood pressure, since the blood pressure can dramatically increase.
- Extended release
