Our bottom line

  • Also treats and prevents many non-heart problems, such as tremors, anxiety, migraines, and liver disease symptoms.

  • 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.

Final section. Do you want to return to drug navigation?
The FDA category for this medication is C. It is advised that you: Weigh risks vs. benefits
  • Since it slows my heart, calms anxiety & tremors-i wrongly assumed I should take it at night. Turns out-it affects sleep!!! Negatively, that is.
  • The first few weeks of taking it I would lay down and be gone in seconds. Some days depending on sleep and work I still do taking hat but some nights I can be up a few more hours than usual.Ex. 10-11 I take it. 1-2 I usually am out.
  • Risks from our pharmacists
  • Cases of heart failure due to taking Inderal (Propranolol) have been reported. Tell your doctor if you noticed increased swelling around your legs or ankles, sudden weight gain or sudden shortness of breath as these may be symptoms of heart failure.
