Propecia is an efficient medicine used to treat male pattern baldness that is believed to be caused by DHT - a metabolite of testosterone that may be responsible for the destruction of hair follicles causing the condition. At the same time DHT is critical in the functioning of the central nervous system, prostate and testicles. Propecia works by preventing testosterone from converting to dihydrotestosterone, therefore reversing the process of hair thinning and helping to re-grow hair. The effects of Propecia have been demonstrated in a series of scientific experiments with several thousands of male patients participating.
The active compound of Propecia (finasteride) is classified by the FDA as pregnancy category X, which means it is capable of causing birth defects in an unborn baby. It's therefore not recommended to women that are pregnant or going to conceive to handle crushed tablets of Propecia to avoid serious health issues. Exposure to the tablets when they are protected by the coating is not dangerous as long as the tablet isn't swallowed. As with most medicines Propecia sometimes causes a number of side effects, such as headache, skin rash, swelling in the limbs, dizziness and loss of interest in sex.
