Finasteride – all you need to know

What are Finasteride tablets? And what are they used for?

 

Finasteride belongs to the group of medicines called 5-alpha reductase inhibitors.

If you have been prescribed Finasteride 1mg, it’s because you have male pattern hair loss (also known as androgenetic alopecia). Men with mild to moderate, but not complete hair loss, can benefit from using Finasteride 1mg tablets as it can prevent further hair loss.

Finasteride 1mg tablets block an important enzyme (Type II 5α-reductase), which is involved in the regulation of the hair follicle. In the scalp, Finasteride specifically lowers the levels of DHT, a major cause of male pattern hair loss. In this way, Finasteride 1mg tablets can help to reverse the balding process and prevent further hair loss.

 

What you need to know before you take Finasteride 1mg tablets

Do not take Finasteride 1mg tablets:

  • If you are allergic to finasteride or any of the other ingredients of this medicine.
  • If you are a child or adolescent.
  • If you are a woman; Finasteride 1mg tablets have been found to be ineffective in the treatment of hair loss (androgenetic alopecia) in women in clinical studies.
  • If you are already taking finasteride or any other 5α-reductase inhibitor for benign prostatic hyperplasia (BPH) or any other condition.
