I recently started taking proscar in addition to the doxazosine I’ve always taken for BPH. I soon noticed that my pulse goes quite high (95-100 bpm)and stays there if I have a glass or two of wine; even hours after I stopped having wine. None of the literature mentions such a side effect, but is that the likely reason.
You need to speak with your doctor regarding these symptoms! You may have a heart condition unrelated to the medication you are taking. If medication is the only issue, I would suspect Doxazosine which can lower your blood pressure and cause a higher pulse rate. Your medical problem may be more than a medication issue. You really need to speak with your doctor.
