Common questions
ED & Blood Flow FAQs
How do ED medications work?
Most common ED medications are PDE5 inhibitors, which improve blood flow to support an erection in response to arousal. They do not work without stimulation, and they are not appropriate for everyone, particularly people taking certain heart medications. A clinician assesses suitability.
Sildenafil or tadalafil, what's the difference?
Both are PDE5 inhibitors. They differ mainly in how quickly they act and how long the effect lasts, sildenafil is shorter-acting, while tadalafil lasts longer. Which, if either, is appropriate is a clinical decision made after an evaluation. This page does not recommend a specific medication.
Is ED linked to cardiovascular health?
It can be. Erectile dysfunction is sometimes an early sign of underlying cardiovascular issues, because both involve blood flow. That's one reason a proper evaluation matters, a clinician can consider your broader health, not just the symptom.
