Phosphodiesterase-5 Inhibitors (PDE-5 Inhibitors) for Erection Problems and Benign Prostatic Hyperplasia
How Well It Works
All PDE-5 inhibitors are very effective in treating erection problems, no matter what is causing the erection problem.Reference 1
How well the PDE-5 inhibitors work depends on the person taking it and how much he takes. But these medicines seem to work in about 7 out of 10 men who use them for erection problems.Reference 2
The medicine needs to be taken before you plan to have sex:
- Sildenafil starts to work as soon as 30 minutes and up to 4 hours after you take a pill.
- Vardenafil starts to work as soon as 30 minutes and up to 4 hours after you take a pill.
- Tadalafil starts to work as soon as 20 minutes and up to 36 hours after you take a pill.
PDE-5 inhibitors, such as tadalafil, may help reduce BPH symptoms in men (whether or not they have erection problems). Men have about a 5-point reduction in their symptom scores on the Reference American Urological Association symptom index.Reference 3
