Does finasteride cause high blood pressure?

8 Answers

From my experience, I believe it rises my lower pressure by 10 after 2 weeks of finasteride. After stopping the medicine, the effect went away. I measured(luckily, as normally I don't believe I had an issue with this, so never would have done so on purpose) my blood pressure before taking the medicine at a normal128/81, and after about 10 days taking the medicine, I measured 136/94(highest record)and multiple measures at about 135/89.

After finding previous posts of this topic here, I stopped taking the medicine, after just one day, the pressure is back to normal at 122/83(one measure), on the second day, it averaged 122/83(two measure), on the third day, it averaged 123/83. Among these days, now 5 days after, I had readings like 119/71, 123/80, 116/85, 125/82.

Another issue with finasteride is possibly (I suspect after reading some online post) the increased reading of serum CA72-4, and in my case the reading is way higher than normal...



am lucky to have this experience, because before and after taking the medicine, I happen to have medical check up. Thanks to the previous post, otherwise I would not have any idea of the side effect.

I've been on Finasteride about a year now and have had elevated blood pressure that just won't go down. I am on high blood pressure medicines but I find it to be very high at 189/87. This week I am paying more attention to my eating habits, no/low salt and low fat intake and monitoring my blood pressure also starting this week. I take the blood pressure results in the morning, at noon, at 3pm, 6pm and before bedtime. I take Finasteride at 3pm. The blood pressure pills tend to bring it down in the morning, to 143/70, however at 3pm it rises quickly to 189/87. I will stop taking it today and repost results. Hopefully they will add High Blood Pressure to the list of side effects for this medication, as I have not found that on any other website, but seeing all these posts indicate otherwise.

After taking Proscar for 17 years my Urologist told me to quit taking it that my prostate was small enough. I have been taking Blood Pressure meds about the same time line. Three days after quitting Proscar my Blood Pressure and Pulse has dropped so much I had to quit taking the Blood Pressure Meds... Anyone else with this problem ?

MY BP is normally about 150/90. I started taking finasteride and it jumped to 180/110 within two days and stayed there. I discontinued it and my BP started going back down after about a week. I waited two more weeks, and then started it again just in case the first high BP was due to something else. MY BP went back to 180/110 within two days. I'm quitting it again, permanently.

I go to the gym almost daily and am taking BP and rarely, I experience BP elevation. But when I started taking finasteride my BP averages 155/100. I have read comments from others in this website about their experience of BP elevation when taking finasteride, but lowering it when they stop taking the med. Thus, I will stop taking the medication; hopefully, it'd address the issue.

I took finasteride and with in a few weeks I had to go the the emergency room with a bp of 224/111. After four episodes I finally quit taking the medicine and have not had any extreme episodes since. Doctors never picked up that this was the cause. Am I the only one that has had this side effect?

I believe propecia is kicking up my systolic BP by about 25 points. My diastolic is always ok.

Funny about that, I started finasteride and within 2 weeks had to go to the ER with a 211/105. I haven't stopped taking it because there was another BP med I started taking around the same time, so I'm stopping the BP med first and then finasteride, will let you know the results...

I started taking finasteride about 3 months ago. My BP was about 135/75. I went to the doctor one month ago and it was 160/100 and this week it was 171/115. I was very happy to see your comment as BP change was not listed as a side effect in the literature received with my prescription.
I quit taking it yesterday and my BP was 137/70 at noon today. Thank you gbeck for posting.

I took Propecia for 3 weeks, experienced tightness of the chest and 201/101 BP along with "severe" nose bleeds. After 2 weeks the nose bleeds have stopped and BP has dropped to 146/96, which I'm hopeful will continue back to my 115/60.
Hope this is helpful and saves a life, there are times when the risk does not exceed the gain.

High blood pressure is not generally considered to be a side effect of finasteride. In fact, one of the side effects sometimes experienced is low blood pressure!

Hope this helps.
