Yes, you can switch to Propranolol SR 20 mg once daily if IR twice daily is not working well. It is clinically acceptable and often better tolerated. However, consult your prescribing doctor before making the change yourself.

At first I will advise to any of the person not to adjust dose on own Kindly do discuss with your respective doctor and optimise dose accordingly Raised pulse rate may be found in various condition as anaemia, hypothyroidism, fever etc Detailed assessment and history taking us required for evaluation to reach a proper diagnosis for planning medications accordingly

If the doctor prescribes you can take the same. Good luck
