2 Weeks After Starting Finasteride, A Bald Spot Appears

I am a 47 year old male who has been using rogaine for 4 years to “contain” male pattern thinning. I recently started taking finasteride to see if that would help more. I started taking 2.5 ( 1/2 of the 5mg pills) for a couple of weeks and have noticed a small but very noticeable bald spot develpoing at the very front of my hairline! ( it was always thick there) Is is possible that the finasteride could cause this? I have started to cut the pills into quarters as it seems like 1mg daily is the recommended dosage. Should I stop the finasteride? I am about to start taking synthroid as my T-4 totals are a bit low and I know that the thyroid can cause hair loss but I think it has something to do with the finasteride.

The recommended dose of finasteride for the treatment of male pattern baldness (MPB) is 1mg orally each day. Taking more will not have a greater benefit. I doubt that taking 2.5mg a day has caused you to lose hair on the front and I would not recommend stopping the medication without discussing these issues with the doctor who prescribed you the medication. There may be other causes of hair loss that you are not aware of and your doctor will be able assess this as he/she is able to physically examine you.
