Is 60mg of Inderal Daily Safe for Managing Heart Rate and Anxiety? - Cardiology

Regarding the dosage of Inderal?


Hello Doctor, I have hypertension and hyperthyroidism, and I tend to be easily anxious.
My heart rate usually ranges between 95-110 beats per minute, and I often feel uncomfortable.
I visited a doctor who prescribed me Inderal (propranolol) 10 mg, with a dosage of two tablets three times a day to help control my heart rate.
After taking Inderal, my heart rate does decrease to between 80-90 beats per minute, which feels quite good.
However, I would like to ask the doctor if taking six tablets of Inderal a day, totaling 60 mg, is too high of a dosage? Will long-term use of this medication have any effects on my body? Thank you, Doctor.

More Info


When considering the use of Inderal (propranolol) at a dosage of 60mg daily for managing heart rate and anxiety, it is important to understand both the medication's pharmacological properties and the individual patient's health profile. Inderal is a non-selective beta-blocker commonly prescribed for conditions such as hypertension, anxiety, and certain types of heart rhythm disorders.
In your case, you mentioned that you have hypertension and hyperthyroidism, along with a tendency to experience anxiety, which can contribute to elevated heart rates. The prescribed dosage of Inderal, as you noted, is 10mg taken three times a day, totaling 60mg. This dosage is within the typical range for managing anxiety and heart rate issues, especially in patients with your health conditions.
However, it is crucial to monitor the response to this medication closely. While many patients tolerate this dosage well, some may experience side effects such as fatigue, dizziness, or bradycardia (a slower than normal heart rate). Since you reported that Inderal effectively lowered your heart rate to a more comfortable range (80-90 bpm), it seems to be working as intended.
Long-term use of Inderal at this dosage is generally considered safe for most patients, but it is essential to have regular follow-ups with your healthcare provider. They can monitor your heart rate, blood pressure, and any potential side effects. Additionally, since you have hyperthyroidism, managing this condition effectively is crucial, as it can influence your heart rate and overall cardiovascular health.

It's also worth noting that anxiety can significantly impact heart rate and overall well-being. While Inderal can help manage the physical symptoms of anxiety, it is often beneficial to incorporate other therapeutic approaches, such as cognitive-behavioral therapy (CBT), relaxation techniques, or lifestyle modifications, to address the underlying anxiety itself.
If you ever feel that the dosage is too high or if you experience any concerning symptoms (such as excessive fatigue, dizziness, or a heart rate that drops too low), you should reach out to your healthcare provider immediately. They may consider adjusting the dosage or exploring alternative treatments that could be more suitable for your situation.

In summary, a daily dosage of 60mg of Inderal can be safe for managing heart rate and anxiety, particularly in the context of your health conditions. However, ongoing communication with your healthcare provider is essential to ensure that the treatment remains effective and safe over time. Regular monitoring and a holistic approach to managing both your physical and mental health will contribute to better outcomes.
