Suggest Treatment For Palpitations And Headaches When On Tazloc

I am 50 years old and I am taking aten50 for last 15 years for the reason high pulse rate. Yesterday my Dr. prescribed me Tazloc40. I have taken tazloc40 in the morning but I have palpitation and headache, so I have taken aten25 in the afternoon and in 10-15 minutes I relaxed. What is the reason ? whether I have to take only aten25? My B.P. was 140/80, yesterday. Please guide me.

Hi,

Since you are on a long-term beta-blocker, there is a possibility of up-regulation of beta adreno-receptors i.e. number has increased. Hence on withdrawal of atenolol your heart rate had gone -up and on re-introduction rate has settled down. You need to continue with a low dose of atenolol.

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