Finasteride Is Making Me Aggressive and Horny!

Dr Rassman, I have a very serious question and I trust you will treat it as such. Over the past two years of taking Proscar split into quarters, I have noticed a ridiculous, almost insatiable increase in sexual desire. I mean its always been there before but I believe its increased dramatically. I’m also finding women attractive I never before felt attracted too. Every second woman I see these days seems incredibly attractive to me and I usually lust after them which is just ridiculous! Also occasionally I have noticed that I can be filled with intense rage and aggression for no reason at all which usually lasts about 30 mins to an hour its almost like i’m full of insane amounts of testosterone temporarily. At these times I feel like I want to run through a brick wall for fun, or break walls with my fists (scary i know) Its almost like a form of roid rage! Not that ive ever taken steroids. But its my understanding that Finastraside lowers DHT and increases free testosterone floating in the body. Could this be a possible reason for what i’ve mentioned?

I guess in a nut shell im asking…

Does Propecia make you more horny?

Has Propecia ever been known to increase anger or irritability?

Finasteride has been reported to increase testosterone by 18% on average. I have had reports from many patients that their sex drive has increased and some wives reported that to me in their older husbands. I have not heard about the degree to which you report the drug impacts you. You might measure your testosterone before you stop taking finasteride, and then measure it again a month after you are off the drug. That would give you an answer. Be warned though, if you saw benefits from treating your hair loss with finasteride, your hair loss might start up again when you stop the drug.

Stinging Eyes After Using Rogaine Foam

Dr. Rassman,

I recently started using Rogaine foam. I applied it at around 7pm and went to bed around 1 am. I wanted to be sure i didnt react negatively. I was fine until after i went to bed. Around 6 am i woke up with stinging and tearing up in both my eyes. I had to go to the bathroom and rinse out my eyes for about a minute. They were all red and puffy too. It seems like it might have been an allergic reaction, but is there also the possibility that some of the foam residue got onto my pillow and i rubbed my eyes into it during the night?(Because i applied a lot and all over my head). Also, after washing out my eyes i was fine. Have you heard of this before?

Minoxidil can be irritating and if you did get any into your eyes, what you are reporting is logical. If it should happen, be sure to wash out your eyes, under a shower with the water pouring into your eyes from hitting your forehead.

Finasteride tissue levels

So if tissue levels remain for 6 days, would topical application every 4/5 days be theoretically still somewhat effective?

Some amount of finasteride stays in the tissues for more than two weeks after stopping the pill. Daily dosing is the ideal way to build appropriate tissue levels.

Strattera (ADHD Medication) and Hair Loss

My 18 year old son is showing an over-all thinning of his hair. When his hair is wet, I clearly see his scalp. He takes fish oil capsules every day and he uses Strattera, 90 mg daily. Other than this, I can think of nothing that could be contributing to the thinning. Do you have any reports of Strattera causing hair loss? Thanks.

The most common cause of hair loss in males is androgenic hair loss or male pattern hair loss. It may start as early as their teenage years. Now add to this the medication Strattera (said to produce hair loss — see ADHD Message Board) and you complicate the hair loss presentation. Your son should discuss this with his prescribing doctor. You need a good doctor working on a Master Plan for hair loss (worst and best case) for him.

Finpecia Worked Great for Years, Then Suddenly Stopped

Hi Doctor,

At age 23, I started taking Propecia. I soon switched to Finpecia made by Cipla to save on costs. For three years things were great. I regrew hair on my crown, no more small baldspot and no noticable hair falling out whatsoever. It was everything I hoped for.

This January, after aproximately 3 years on Finpecia, I noticed my hair thinning out and everyday I see that I am losing hairs. I still have decent coverage on the crown but my hairline is receeding and it’s definitely thinner coverage all over.

I’ve been taking some supplements such as saw palmetto and been using 2% Nizoral. I’m wondering if adding Rogaine Foam may be to some benefit.

Also wondering, if in your experience, you think I should get back on the name brand propecia. I’ve been getting the Finpecia from a reliable online pharmacy that requires a prescription and is “certified”, but I wonder if the quality of drug is different.

Thanks for your help and I appreciate this blog.

CiplaFor those readers not familiar, Finpecia is a generic Propecia (1mg finasteride) made in India by Cipla — the generic 1mg isn’t available legally in the US yet due to patent laws. And just like Propecia, it does not continuously work for everyone. Many men on finasteride will see results for 5-10 years (or beyond), but each case is different. You need to see your prescribing doctor about the reduced impact of this drug. I think you should still stay on the medication, because if you stop it you will likely lose a great deal of hair.

Cipla is a huge pharmaceutical company and I doubt there’s a difference between the generic and the name brand finasteride.

As for adding Rogaine Foam, I suppose it’s worth a shot. You might see some benefit, but I can’t say for sure.

Study – Isolated Crown Balding and the Risk of Prostate Cancer

Snippet from the abstract:

Androgenetic alopecia (AGA) is a genetically determined skin condition strongly age dependent and androgens are assumed to play an important role in its development. A link between AGA and prostate cancer has been hypothesized because of their similar risk factors.

We sought to systematically review the evidence available on the association between AGA and risk of prostate cancer.

We searched the electronic databases MEDLINE and Cochrane for studies examining the association between AGA and risk of prostate cancer. We estimated pooled odds ratios (OR) and 95% confidence intervals. We also analyzed the OR for individual hair loss patterns, as defined by the Hamilton scale.

Read the rest — Androgenetic alopecia and risk of prostate cancer: A systematic review and meta-analysis

Although many authors have investigated a possible association between androgenetic alopecia (AGA) and prostate cancer, there is not yet a definitive answer. Patients with any pattern genetic balding did not have an increased risk of prostate cancer, but patients with just vertex pattern AGA (crown balding without balding in other areas) had a significantly increased risk of prostate cancer versus control subjects. Vertex pattern AGA may be associated with an increased risk of prostate cancer.

In another publication, there was a higher risk of heart disease in patients with pure crown balding.
