My urination frequency has increased after switching from Finasteride to Dutasteride

[dirtylarry]

So I started on Finasteride around 2007 and have been taking it continuously since then.

Around 2017 I started taking Dutasteride once a week which I then upped to twice a week and now three times a week.

For most of that time I continued to take finasteride except on the days I was taking Dutasteride and over approximately the last year I have basically stopped the finasteride and just focused on the 3 Dut a week.

Now I have no idea if this is related to the above but over the last year the amount I need to urinate during the night has increased a lot to the point where it disturbs my sleep.

I dont know if this is

• Unrelated to the medication or 
• Because of dropping the finasteride or
• Because of taking up Dutasteride

I know frequent urination is related to enlarged prostates. And I know both Fin and Dut are used to treat that. So Im confused why I would be experiencing this. Any thoughts?

I started on Fin for a year and had zero sides. Switched to Dut 2 years ago and still have zero sides. 

I would say the urinary thing is unrelated. If say you were getting erections fine on Fin and suddenly cant get it up on Dut, now that would be the Dut.

The most common cause of high frequency of needing to urinate is an enlarged prostate. It just seems weird that the drugs Im taking are actually to treat enlarged prostates (Fin and Dut).

I got similar symptoms on finasteride. Just wrote a post actually before I saw yours.
