Hair loss and prostate drugs linked to persistent erectile dysfunctionStaff Writer | March 13, 2017
Men with longer exposure to the drugs finasteride and dutasteride had a higher risk of getting persistent erectile dysfunction than men with less exposure, reports a new Northwestern Medicine study.
Consequence Sildenafil is not of much help
Among young men, prolonged exposure to the drugs posed a greater risk of persistent erectile dysfunction (PED) than all other assessed risk factors.
This means there is a stronger relationship between taking these drugs and having PED than having diabetes, hypertension or smoking, which are other risk factors.
Persistent erectile dysfunction continued despite stopping the drug and continued despite taking sildenafil (Viagra) or similar drug.
Prior to the new study, there was no strong evidence that finasteride and dutasteride cause sexual problems that continue after men stop taking them.
There also was no strong evidence that taking these drugs for a longer time increases the chance of experiencing sexual problems.
Finasteride and dutasteride are drugs that are male hormone blockers. These drugs block the conversion of testosterone to its more active form, 5 alpha dihydrotestosterone.
Finasteride is prescribed to some men with prostate enlargement or baldness. Dutasteride is prescribed to some men with prostate enlargement.
Propecia and Proscar are brand names for finasteride. Avodart is a brand name for dutasteride. Jalyn is a combination drug containing dutasteride and tamsulosin. ■
