How does it works?
Finasteride is a substance contained in Propecia hair loss drug. This preparation is only for men when the substance may cause severe damage to the fetus in pregnant women.
Propecia works by inhibiting the enzyme 5-alpha reductase, preventing testosterone form conversion to dehydrotestosterone, or DHT. DHT is the substance that causes male pattern baldness, and to some extent also female pattern hair loss – that is, genetic hair loss. It is the individual sensitivity to the enzyme that determines how strongly the hair loss will be. At genetic hair loss the growth of new hairs is inhibited whilst the existing shrink and eventually disappear. By reducing the sensitivity to the enzyme and thus the formation of DHT finasteride slows this process and allows new hair to regrow.
How is Propecia taken?
In MPB, 1 tablet of Propecia (finasterid 1 mg) is taken daily with or without meals. There is no evidence that an increased dose results in increased effect. Efficacy and duration of treatment should continuously be assessed by the treating physician. It generally takes three to six months of daily treatment, before signs of stabilization of hair loss can be expected. Continued treatment is recommended to maintain the effect. Discontinuation of treatment will lead to the positive effects which begins within 6 months and returns to baseline by months 9 to 12.
Propecia dose of finasteride is 1 mg, as opposed to Proscar that contains finasteride 5 mg. Propecia for hair loss is taken at the dose of 1 mg on daily basis during the minimally effective period of time (at least 6 months).
What you should know before taking
As far as Propecia prescription is concerned, the drug is appointed to individuals with no contradictory comorbidity conditions and those without known allergies towards the drug and its components. Check for the list of Propecia contraindications below on this page (this might not be full) and manufacturer’s instruction found in the original drug package.
According to the manufacturer that refers to several decades of clinical studies, Propecia has no known contraindications apart from gender. Finasteride is absolutely not intended for use in women because of dangers it may pose in terms of hormonal disruption and / or damage to fetus and suckings in pregnant / breastfeeding women, respectively.
This begs the questions, is Propecia safe for every patient category? The answer is yes, with minor reservations made for the cases of individual intolerance and allergies towards the drug or its components. It is a good idea to discuss your concerns with prescriber before taking drugs containing finasteride.
No interactions of Propecia have been identified in the course of clinical studies. Although the risk for finasteride to affect the kinetics of other drugs is considered small, it is probable that inhibitors and inducers of cytochrome P450 3A4 (propranolol, digoxin, glyburide, warfarin, theophylline and phenazone) may influence the plasma concentration of finasteride. Based on established safety margins, an increase in the plasma concentration due to concomitant use of such inhibitors is probably not of clinical significance. The effects of simultaneous use of cytochrome P450 3A4 inhibitors and finasteride has been tested in humans and no clinically significant interactions have been found.
Propecia contains lactose monohydrate as a filler. This information should be taken into consideration by individuals suffering from lactose intolerance. If your prescriber considers the benefits of the drug’s use prevailing over potential risks, continue with the therapy under a doctor’s guidance and monitor your bodily reactions closely and regularly.
Propecia as such has practically no side effects, but there is one adverse event that is commonly attributed to the use of finasteride containing pharmaceuticals, and it is erectile dysfunction (ED, impotence). A significant drop in libido is also observed in reports of patients in the later stages of Propecia therapy course. It is not, however, clinically proven that side effects of Propecia include ED or diminished libido. In patients taking Propecia erectile dysfunction is statistically higher in occurrence as patients advance into their treatment course, but the symptoms are also reported to disappear as the course continues.
Crushed or broken tablets should not be handled by women who are or may become pregnant, because of possible absorption of finasteride with consequent potential risk to a male fetus.
