There are some options that might be a better fit for those looking to avoid taking finasteride.
Potential Alternatives for Finasteride
Dutasteride (Avodart) is also for the treatment of both male pattern baldness and enlarged prostate. It has many of the same side effects, though. It is a very similar drug. It belongs to the same class as finasteride.
Alpha-blockers such as doxazosin (Cardura XL, Cardura) can help control the symptoms of benign prostate hyperplasia (prostate enlargement). They work by relaxing the smooth muscle in the prostate and bladder, reducing the blockage.

What is Finasteride?
Finasteride is a 5-alpha-reductase inhibitor sold under the brand names Proscar and Propecia.
What is Finasteride Used For?
It is used for the treatment of enlarged benign prostate hyperplasia (enlarged prostate) when offered under the brand name Proscar. For benign prostate hyperplasia, the goal is to reduce symptoms associated with the condition, such as difficulty urinating. It takes six or more months to see improvement.
Propecia is for the treatment of male pattern hair loss.
How Does Finasteride Work?
It works by decreasing the production of the hormone dihydrotestosterone (DHT) in the body. DHT can trigger the enlargement of the prostate and even contribute to hair loss. Reduction of this hormone can therefore prevent prostate enlargement as well as decrease hair loss.
How Long Does it Take for Finasteride to Work?
How long it takes to work depends on the form of the drug taken. For hair growth, it can take three to four months before the medication begins to affect. It will be six to nine months before there is significant hair regrowth.
For benign prostate hyperplasia, it takes six or more months to see improvement in relevant symptoms.
