Hi, Can I take a viagra? If yes, on what doses? I m 34 year old male. Physically healthy with good medical checkup report, but in June 2016 I had one stent implanted on my heart due to SCAD. Right now everday I m taking Aspirin 100mg & Glycine 45mg, Clopidogrel 75mg, Perinpopril 4mg, Bisoprolol fumarate 2.5mg, and lastly Atovarstatin 20mg. To add more concern, I believed I have erectile dysfunction (ED) Advice please. Thanks.
