A male patient is being treated for benign prostatic hyperplasia (BPH) by another provider but cannot remember which drug he is taking. He comes to the clinic seeking treatment for erectile dysfunction and receives a prescription for sildenafil [Viagra]. What will the nurse teach this patient? a."Sildenafil is not safe to take in conjunction with finasteride [Proscar]." b."Sildenafil is safe with any medication for benign prostatic hyperplasia." c."To be safe, you should have a transurethral resection before starting sildenafil." d."You should not take sildenafil if you are taking silodosin [Rapaflo]." - Correct Answer ANS: D Sildenafil should not be taken with alpha1-adrenergic antagonists, such as silodosin, because of the risk of severe decreases in blood pressure. Finasteride is not an alpha1-adrenergic antagonist and may be taken with sildenafil. Not all medications for BPH are safe to take with sildenafil. Invasive treatments for BPH are used when symptoms are severe.
