Doctors recommend Propecia to treat BPH or Benign Prostatic Hyperplasia, commonly referred to as the enlargement of the prostate. The United States Food and Drug Administration or US FDA approves the 1 mg dosage every day.
However, some studies have shown that the dosage of Propecia required to treat male baldness might be smaller.
Based on a study by JE Edwards and RA Moore available in PubMed Central, regular treatment with Propecia (about 6 to 8 months) is needed to ascertain the efficacy of the drug.
Once treatment is discontinued, any curative gains will reverse within six to eight months. The research also suggests that Propecia can treat symptoms linked with BPH, particularly in the urinary system.
In another study about men suffering from mild hair loss, it has been found that 2 out of 3 men who were treated with Propecia had the ability to grow some hair.
On the other hand, those men who were not treated with Propecia continued to lose hair. The average hair count for the controlled group persisted on above the baseline during the course of the five-year research.
According to Simone Rossi in her book Australian Medicines Handbook, Finasteride or Propecia is effective in combating hair loss only during active treatment since the hair loss will persist within a few months of discontinued treatment.
In a series of clinical studies conducted by Dunlap, Miller, Winters et al, Propecia is proven effective in fighting hair loss in the hairline and crown area. However, it has been found that it is more effective in the crown.
In almost a decade study subjecting 118 men in varied ages who had been treated for hair loss using 1 mg of Propecia once a day, it has been found that 86% of the patients had long lasting benefits to treatment after a decade.
This shows that most men have increased their chances for stable rates for growing hair, and only 14% of the men experienced losing hair.
It is also interesting to take note that those men who had experienced hair growth during their first year of treatment had better chances to grow hair after five years.
Sixty nine percent of these men experienced sustainable hair growth. Meanwhile, those who have experienced no hair growth during the initial stages of treatment were found to have increased their rate of hair growth.
Moreover, those men who were 30 years above have the tendency to experience increased hair growth, apparently because of the fact that they have already accustomed to hair loss in their age.
Side effects were experienced by just about 6% of the subjects, and no patients experienced depression.
The authors of the research, Bunagan, Banka, and Shapiro concluded the effectiveness of Propecia in the treatment of hair loss in patients over 40 years.
This research particularly concentrated on users who had continued using the treatment using Propecia.
In a hormone study conducted by Gooren, Propecia is also used for hormone replacement therapy transgender operations. However, there are still points of investigation in this Propecia’s off label use.
