What is Finasteride?
Simply put, Finasteride is a medicine given to treat common hair loss patterns in men. You might also find it sold under brand names like Propecia in local pharmacies.
This medicine belongs to a group of drugs known as 5-alpha reductase inhibitors. That sounds a bit complicated, so let us break it down into simple terms.
Your body naturally makes a hormone called testosterone. This testosterone turns into another chemical called dihydrotestosterone, which is known as DHT. DHT is the main culprit that causes your hair roots to shrink and your hair to fall out.
This Finasteride medicine stops that exact conversion process from happening. When DHT levels go down, your scalp stops thinning, and new hair can start growing back healthy and strong.
Things to Tell Your Doctor Before Taking This Medicine
Before your doctor writes a prescription for this medicine, you must share your complete medical history. Do not hide anything, because this information protects your overall health and safety.
- Tell your doctor if you have any liver disease or problems with how your liver works.
- Let your doctor know if you are allergic to Finasteride, other medicines, specific foods, or medical dyes.
- Inform your doctor if your partner is currently pregnant or actively trying to get pregnant.
