Should Propranolol And Methimazole Dosages Be Increased To Manage Heart Palpitations Due To Hyperthyroidism?

default
Posted on Thu, 7 Mar 2019
Question: hi, I have hyperthyroidism and I have been feeling very symptomatic the last 2 days. I currently take propranolol (20 mg twice a day) and methimazole (5 mg once a day.) I've been having heart palpitations frequently tonight, but my heart rate is fine. (in the 70's) I'm wondering if I am able to increase the dosage for my medication to help with these hyperthyroid symptoms for tonight until I can call my doc after work tomorrow?

Brief Answer:
Propanolol can be increased by another dose.

Detailed Answer:

Hi,

Yes. You can increase the dose of propranolol by one more dose which helps palpitations.

Since Heart rate is still good you can do it. Also, check your BP. If it is not unusually high or low you can stay else please reach to ER.

Hope I have answered your query. Let me know if I can assist you further.
