My BP remanis 130/85 with medicine and almost in control all the time.i have recently expirenced first time problems with erection. this happens 2 times in last one week. overal desire has also decreased then before. i was also experiencing problem with urination. (but just mild straining) nothing big.. or troublesome from last few months. which if i drink water and have regular walk goes ok.My cardiologist has just changed my current medicine from concor 2.5 (once) to telma 40(once) after i explained him above. My all reports of blood, urine, liver function, kidney function, 2D echo, TMT has come absolutely normal.My question is the change in medicine is ok ? or should i take telma 20...? my weight is 78 and height is 170. Is the problem which i am facing is due to taking BP medicine uptill now ? is there a way to manage BP and stop medicine ? Is the change from Concor 2.5 to telma 40 ok?

Dear Davit Meta, It is a very good idea to change Concord to Selma. Usually I try to avoid prescribing beta blockers (medications such as Concord) to young men. You should take Selma and see if the dose is appropriate for you, as it is quite individual. You should strictly follow healthy lifestyle, and after some time try to reduce the dose of your medication. In some young patients, we succeed to with Chat Doctor. Hope I could help nourishing you good health In case of further questions don't hesitate to ask
