I am new here and have done a quick search but didn't find anything on the specific side effect. I have been taking Tamsulosin for about a month now without any of the noticeable side effects mentioned on the NHS website. The issue I appear to have developed came on over the last week during exercise. I am relatively fit, and while riding I monitor HR, distance, cadence, power etc. so have a good idea what my normal is. The last 2 rides have seen a drop of about 10bpm during a steady ride, and an inability to get even close to my max HR during intervals or hilly sections of rides. I seem to be stuck at 130bpm, almost like the HR monitor is malfunctioning ( I have checked, it's not) The only other medication I am taking is 10mg of Citalopram and have been on this for years so nothing new there. Anyone else experienced this or am going to have to go on a Covid dodging mission and visit a GP?
Thanks in advance
