Can I take a PDE5 inhibitor medicine for erectile dysfunction along with this Aspirin, Clopidogrel and Rosuvastatin capsule?

This is a combination usually prescribed after a cardiac event or for significant heart risk, and ED medicines can occasionally interact with heart medications, especially if you're also on nitrates, so this really isn't a question to guess your way through. The bigger factor is your underlying heart condition itself - that determines whether ED medicines are safe for you at all. Please check with your cardiologist before combining the two.
