Better to avoid Tazzle
I went through the query and understood your concern.
You are already on many medications that act on cardiovascular system like coversyl
8mg,Aquazide 12.5 mg to reduce BP,Aspirin
to prevent clotting and Calaptin SR 120 for cardiac arrhythmia
or other cardiac problem.
In such condition taking Tazzle may cause cardiac problem as this can further reduce BP causing hypotension
/ erection may not be possible or can affect heart. So for my patients I don't recommend Tazzle and so I don't recommend for you.
I hope this information helps you and answered your questions.
Feel free to ask for any further queries. I will be glad to answer them.
Wish you good health.
