Inderal Use for Heart Rhythm Issues and Anxiety Management - Cardiology

I am experiencing shortness of breath and chest tightness, mostly in the early morning after waking up or after meals.
I have consulted specialists in pulmonology, cardiology, and gastroenterology.
The gastroenterologist diagnosed me with gastroesophageal reflux disease (GERD) and prescribed medication for it.
The pulmonologist and cardiologist conducted tests and found no issues.
The cardiologist prescribed Inderal (propranolol) for what he suspects is arrhythmia, advising me to take one pill in the morning and one at night.
He also prescribed Xanax, suggesting that my symptoms might be related to anxiety, and recommended taking it before bed to help with sleep.
Currently, I have not taken Xanax, as I prefer to manage my anxiety through relaxation and exercise.
I only take Inderal when I experience shortness of breath, and it does provide relief.
However, I have not followed the doctor's advice to take it twice daily because I notice that my heart rate drops significantly to around 50-60 beats per minute after taking it, which makes me hesitant to take it regularly.
I would like to ask you, doctor, if it is necessary to follow my original doctor's advice to take Inderal twice daily to regulate my autonomic nervous system and achieve full recovery, or is it acceptable to take it only when symptoms occur? My shortness of breath is not associated with a rapid heartbeat; I do not feel my heart racing.
After taking the medication, my pulse is only in the 50s, so I am reluctant to take it twice daily.
Thank you very much for your help.

MIKE, you can take your medication as needed for discomfort, but if the frequency of episodes increases, it is advisable to return to a regular dosing schedule.
If your heart rate is slow and you are not experiencing discomfort, there is no need to worry; just monitor the situation.

More Info


Inderal, generically known as propranolol, is a non-selective beta-blocker commonly prescribed for various conditions, including heart rhythm disorders, anxiety, and hypertension. It works by blocking the effects of adrenaline on the body's beta receptors, leading to a decrease in heart rate and blood pressure. Your concerns regarding the use of Inderal, especially in relation to your symptoms of shortness of breath and chest tightness, are valid and deserve careful consideration.

From your description, it seems that you are experiencing episodes of shortness of breath and chest discomfort, particularly in the mornings and after meals. These symptoms can be distressing and may be exacerbated by anxiety, which is known to contribute to physical sensations that mimic heart problems. Your gastroenterologist has diagnosed you with gastroesophageal reflux disease (GERD), which can also cause similar symptoms, including chest discomfort. It’s important to differentiate between these potential causes to ensure appropriate treatment.

Your cardiologist prescribed Inderal to help manage your heart rhythm issues, and it appears that you have been taking it on an as-needed basis rather than as a scheduled medication. While it is understandable that you are hesitant to take it regularly due to concerns about a slow heart rate (bradycardia), it is crucial to follow your doctor's recommendations for consistent use unless otherwise directed. Inderal is often most effective when taken regularly, as it helps stabilize heart rhythms and can reduce anxiety symptoms over time.
Taking Inderal only during episodes of discomfort may not provide the same level of control over your symptoms. The goal of regular dosing is to maintain a steady level of the medication in your system, which can help prevent the onset of symptoms rather than just treating them as they arise. If you experience bradycardia (heart rate below 60 beats per minute) that causes you discomfort or other symptoms, it is essential to communicate this with your healthcare provider. They may need to adjust your dosage or consider alternative treatments.

Regarding your anxiety and the use of Xanax (alprazolam), it is understandable that you prefer to manage your anxiety through relaxation techniques and exercise. However, if your anxiety is significantly impacting your daily life, it may be beneficial to discuss the use of Xanax with your doctor. While it is a short-term solution, it can help alleviate acute anxiety symptoms, allowing you to engage more fully in relaxation practices and exercise.

In summary, while you may feel more comfortable taking Inderal only when symptoms arise, following your doctor's advice to take it regularly could provide better overall management of your heart rhythm issues and anxiety. If you have concerns about side effects or the impact on your heart rate, it is crucial to have an open dialogue with your healthcare provider. They can help you weigh the benefits and risks of your treatment plan and make any necessary adjustments to ensure your safety and well-being. Additionally, if your symptoms persist or worsen, further evaluation may be warranted to rule out any underlying conditions that could be contributing to your discomfort.
