Upsides and benefits
TenexPropranolol
  • 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.
  • A first-choice treatment to prevent chest pain (angina).
  • A first-choice treatment for heart failure, heart attack, heart valve disorders, and abnormal heart rhythm.
  • Also treats and prevents many non-heart problems, such as tremors, anxiety, migraines, and liver disease symptoms.
Downsides and risks
TenexPropranolol
  • 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.
  • 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.
  • Has more side effects than some beta blockers because it crosses into the brain and central nervous system.
  • 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.
  • You can't miss doses. Stopping Propranolol suddenly can cause your blood pressure to go up suddenly, which raises the risk of heart attack and stroke.
