Hair loss coupled with a receding hairline is quite common in men, given the kind of lifestyle we lead and the diet we subject our bodies to. However, there are certain medicative drugs used to counter this issue as a whole. Propecia is one such medication prescribed to male patients suffering from enlarged prostate or hair loss.
The main constituent of Propecia is finasteride. This drug prevents the synthesis of dihydrotestosterone (DHT) from the hormone testosterone. DHT is responsible for disorders such as enlarged prostate as well as hair loss in men.
By inhibiting the production of DHT, Propecia helps to improve the symptoms associated with enlarged prostate such as difficulty in urinating, decreased urine flow, hesitation at the start and end of urination.
It is also known to help reduce the risk of urine retention and the need for prostate surgery. DHT is also the hormone responsible for hair loss in men as it can bind itself to the receptors in your hair follicle causing them to shrink and eventually die. Propecia blocks DHT away from the hair follicles leading to decreased hair fall and increased hair growth.
Propecia inhibits the action of an enzyme called 5-alpha-reductase which synthesizes DHT from testosterone. DHT is the more active form of testosterone responsible for enlarged prostate and hair loss.
Thus, when you stop taking Propecia the enzyme is no longer blocked and after the remaining drug is
excreted out of the body, the body starts to produce DHT again from testosterone. Propecia doesn't cure enlarged prostate and hair loss but only provides relief temporarily.
Once you stop taking Propecia you will be back to your normal rate of hair loss and if taken for enlarged prostate the prostate will start to grow again. Prolonged use of Propecia increases the risk of high-grade prostate cancer.
If you notice any abnormal effects, check with your healthcare professional immediately.
