There are people that claim that long term usage of finasteride can create side effects involving both physical and mental side. The physical related side effect they claim is sexual impotence or erectile dysfunction. The mental related side effect they claim on the other hand is memory loss or memory fog. The fact is, such report secondary effects from long term usage of finasteride is not entirely conclusive. There are a good number of men taking the drug and the condition they claim is somewhat apparent in only a few people, more particularly, those who are claiming compensation from the condition which is why the filed a lawsuit against Merck. If you think about it, their side effect claims seems to be somewhat suspicious.
Finasteride Additional Information
Finasteride comes in two doses – finasteride 5mg and finasteride 1mg. The higher dose goes by the brand Proscar and the lower dose goes by the brand Propecia. Both drugs are approved by the FDA of America for the ailments they are designed for, mainly: finasteride 5mg for benign prostatic hypertrophy, and finasteride 1mg for androgenic alopecia.
At first, it was only finasteride 5mg that Merck intended to release on the market. But during clinical trials of the drug, the subjects that had male pattern baldness reported the ceasing of their hair loss condition. Some even reported have a few hair growth taking place. With this, Merck decided to do further research and testing to get conclusive answers as to what was going on. It was then that they discovered that, finasteride 5mg, at much lower doses, is capable of treating hair loss brought about by androgenic alopecia.
Merck’s research suggested that the ideal dosage for the treatment of male pattern baldness is finasteride 1mg. In the five-year study that they made using the finasteride 1mg, they observed that more than half of those taking finasteride 1mg had ceased hair loss with nearly half experiencing considerable hair regrowth from the condition. As a manner of control towards the experiment, they also made a placebo group with which there were no noticeable changes with the subjects belonging to that particular group. When you compare those that used finasteride 1mg and those that used placebo only, the hair density of those using finasteride 1mg was much thicker than those from the placebo group. This further solidifies the effectiveness of finasteride 1mg in treating hair loss.
Probably the reason as to why finasteride 1mg is very effective when it comes to treating male pattern baldness is because the drug basically treats the hair loss condition at the hormonal levels and not just at the scalp level.
Hair loss from androgenic alopecia is triggered by elevated levels of dihydrotestosterone. What finasteride 1mg does is it limits the high levels of the hormone dihydrotestosterone by limiting its production. It does this by preventing the enzyme 5α reductase from transforming or altering the hormone testosterone in becoming dihydrotestosterone. This in essence stops the hair loss condition caused by androgenic alopecia.
