We have discussed that Erectile Dysfunction (ED) is a known side effect of Propecia (finasteride) and Avodart (dutasteride) in the range of 2% of men taking Propecia (finasteride). The side effect occurs in 1-2% of men. We have also stressed that ED is common in men not taking these drugs. In general ED affects 20% of men in their 20s, 30% of their men in their 30, 40% in their 40s, 50% in their 50s, 60% in their 60s and so on with an impact on 150 million men. ED can also be a sign of vascular disease or other systemic diseases such as high blood pressure or diabetes. Outside of the hair loss topic in BaldingBlog, many medication (other than Propecia) can cause ED or other sexual related issues. Vitamin D deficiency is one of the causes of ED that is easily treated. More notable are the anti-anxiety or anti-depressant medications as well as blood pressure medications. There is also a psychological component to ED where the lack of erection can be attributed to the mind. This is the reason that doctors are needed to diagnose and prescribe the medication.
When a patient is so worried or express anxiety that they may have ED from taking Propecia I can almost predict that they WILL have a side effect as the mind can be a powerful motivator. These patients I tend to generally not recommend Propecia (despite my effort at educating them) since they would be more preoccupied with the side effect than its benefit.
When on occasion a patient report back with some side effect, we decide on the course of action together. They can stop the medication or consider other options such as lowering the dose or taking a medication that may help with the erection problem. We also explore other extraneous causes such as their health, other medications that they may be on, and other emotional factors in their lives. To some, hair loss in it of itself can be a horrible and debilitating emotional trauma. On a few occasion, I have referred patients to a psychiatrist because hair loss affected them to a point of clinical depression and thoughts of suicide.
When a patient is in good mental capacity with extraneous factors accounted fand the patient still expresses the desire to take Propecia, we explore the option of medications to help with the ED. The following medications are used in general to treat ED (irrelevant of Propecia or its side effects).
Tadalafil Mylan (Generics UK Ltd) is used for the treatment of men with erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). It is a generic of Cialis (Lilly), which has been available since mid-November 2002. All of these drugs that I will discuss below require sexual stimulation to work. It is reported to last 48 hours with a slower onset. Some doctors recommend a daily dose of 5mg and this may have positive effects on your prostate as well as your ED.
Avanafil has been approved by the FDA for ED as early as about 15 minutes before sexual activity, although the official time to use it might be 30 minutes which makes the onset much faster than the other drugs.
Viagra was the first drug introduced for ED. It may be the strongest of the medications and many men report that when these other drugs fail, this one works.
There is no good scientific study reflecting men with ED from finasteride using the above treatments, but my personal appraisal and my experience prescribing these medications, these approaches can satisfactorily treat ED even while on finasteride.
