Finasteride (Propecia) and Avodart (dutasteride) cause the lowering of your natural testosterone levels (rarely) leading to side effects such as impotence and prostate problems. In addition, a very small number of patients have reported symptoms of depression and (rarely) suicidal thoughts.

A recent study has concluded:

The incidence of erectile dysfunction, ejaculatory dysfunction and decreased libido resulting in discontinuation from therapy was significantly higher in the dutasteride (5.1%, 2.4%, 2.7%, respectively) compared with the finasteride (2.1%, 1.8%, 1.4%, respectively) group (p < 0.01) (reference Science Direct comparisons of finasteride and dutasteride)

A recent study has shown that patients taking dutasteride (or finasteride) have a lower overall risk of low-grade prostate cancer but a higher risk of more serious (high-grade) prostate cancer. If you have any symptoms such as blood in the urine or difficultly urinating (passing water) you should contact your doctor for advice.

You will need to be aware of the potential longer-term side-effects of taking finasteride - known as Post Finasteride Syndrome - which may also apply to dutasteride - please see our PFS article for more information.

Please speak to our pharmacist if you have any concerns about these issues.

General warnings from our Clinical Lead Dr Roisin McHugh:

1. Finasteride/ Dutasteride has in rare cases caused depression. If you develop any symptoms of depression such as low mood please stop the medication straight away and discuss it with a health care professional.
2. Infertility has been reported in men who took finasteride for a long time and had other risk factors that may affect fertility; this should improve on discontinuation of finasteride/ dutasteride. Long-term clinical studies about the effects of finasteride on fertility in men have not been conducted.
3. Finasteride/dutasteride can affect a PSA blood test result, you must inform your own doctor that you are taking it.
4. You should promptly report to your doctor any changes in your breast tissue such as lumps, pain, enlargement or nipple discharge as these may be signs of a serious condition, such as breast cancer (very rare).
5. It can cause erectile dysfunction. If you have any questions regarding any of this please email or telephone the pharmacy.
6. A small number of men (less than 1%) may experience heart palpitations when taking finasteride for the first time, especially if they are aged over 60, this could also apply to dutasteride.
