Has anyone experienced massive muscle pain while on Proscar / Propecia? It started in the shoulders, moved to the arms and later to the legs. I could hardly get out of bed in the morning...
A CPK test showed an abnormal high level of creatine kinase; 205 Units per liter (Normal is 22 to 198) which according my doctor indicates muscle damage. One week off Proscar and it was down at 25 U/L and no pain...

That's a new one to me as I cannot see how the two are connected.. You are a new poster so can you give us a bit of history..

How long were you taking it?
Any other meds you are taking?
What doc did you go to ( regular doc or specialists)?

I'm sure the anti-Propecia people will be happy to accept this as a common side effect..

If I were you I would certainly stop taking it .

1476 FUT - Dr. True
2124 FUT - Dr. True
604 FUE - Dr. True

My views are based on my personal experiences, research and objective observations. I am not a doctor.

I took it about two months and then of course stopped after the test as I almost felt like a cripple... (doing fine now!). The CPK blood test was taken at a normal hospital - I did/do not take any other drugs so conclusion was based on the fact the pain disappeared as I stopped with Proscar.

I am not trying to add to any pro/con discussion about propecia - just want to hear if I am the only one who has experienced this. Doctor actually said that I could try Proscar again but of course advised to stop immediately if pain should recur.

Any experience shared here is welcome, good or bad. So don't feel that you have to apologize.

That's interesting though..I can't say I ever heard anything like that before.

Did you doctor give you a full examination? I suppose I'm wondering if anything else might be going on. Are you taking any other kind of medication? Perhaps there is some kind of interference of sorts?

I am not taking any medication and have never done. The doctor did a complete blood test and then found the high CPK level.

Searched the web and found that muscle pain / myopathy to some extent has been discussed in connection with Finasteride.
Also, in this year, there is a report showing that in a patient treated for benign prostatic hyperplasia, there is an occurrence of severe reversible myopathy associated with finasteride use, and this was clinically and histologically resembling glucocorticoid-induced myopathy.
The 5-mg tablets have been reported to cause erectile dysfunction, gynecomastia, severe myopathy and loss of libido in older men. Adverse events are reduced with the 1-mg tablets.
And here is a report I can not access but the title is somehow clear.
Reversible severe myopathy during treatment with finasteride

Anyway, just wanted to hear if anybody in this forum has experienced the same or heard about it.

Did some more search on the web and found some discussions on another forum.

I then noticed that 'Corticosteroids' is mentioned which made me remember that I actually used a 1% Hydrocortisone to treat an inflammation during the period where the pain started. Never really thought if there could be a connection as it was just a cream I used.
Not a medical expert, I find it difficult to understand the discussions but this made me think if there could be a connection:

The current case confirms rapidly reversible myopathy as a possible adverse effect of
finasteride treatment, attributable to its structural affinity to corticosteroids.
Anybody who can explain what is meant?

gnaraf, I wish I did know what that meant!
Because I had been using cortisone while takimg propecia.
Good or bad?

There is obviously alot that no one on this forum knows about finesteride.

We could use a scientist, pharmacist or doctor in da house!

Kind of a unique descriptor, but I believe essentially what they are saying is that was an example of reversible muscle atrophy (side effect) from the use of Finasteride due to its similar characteristics to corticosteroids.


By the way I believe that there are a couple of MD members as well as the HT docs ofcourse. We could really use a pharmacist or chemist though.

I am sure many of the (millions of?) men, who take finasteride, also have used cortisone at some point. I just happened to start both almost at the same time and thought that one maybe then could be disposed for these muscle pains.
Hopefully some other people will add to this discussion.
I may end up trying Proscar again to clarify this...
