How does Finasteride work?
The active ingredient in Finasteride is finasteride. This belongs to a group of medicines called Type II ‘5-alpha reductase inhibitors’. These medications work by blocking the action of 5-alpha-reductase which is the enzyme that converts testosterone into dihydrotestosterone. This results in increased levels of testosterone and decreased dihydrotestosterone. This treats male-pattern baldness as dihydrotestosterone causes the hair follicles to shrink. Eventually, the hair follicles get so small that they cannot replace lost hairs.
How do you take Finasteride?
Always take this medication as it has been prescribed to you by your doctor or pharmacist. Take one tablet daily at the same time. The tablet can be taken with or without food. The tablet should be taken whole and should not be broken or crushed.
