Does Propecia Cause Harm to the Liver?

Dear doctor,
There has been few questions troubling me concerning taking propecia.

1) Is there a chance that it could make hairloss even worse than without taking it? (and what exactly people mean by term shedding because of propecia)

2) My doctor and parents are worried because of a bad effect on the liver. How serious is that? What do you think of it?

Thanks

1. Propecia a drug that is prescribed by a doctor after you had an exam that confirmed a diagnosis for androgenic alopecia (also known as male pattern baldness). It is a drug that slows down and sometimes reverses the hair loss process. If taking this drug will make hair loss worse, it would not be recommended by a doctor. Having said that, if your genetic predisposition is so overwhelming and you are destined to be a bald man, the drug will not have a significant benefit. In other words, you may still lose hair despite taking the medication. It is not the medication that makes it worse.

2. In general all drugs are either metabolized by the liver or kidney. Propecia does not cause liver damage, but if your parents and doctors are worried, then you should resolve that issue (valid or not) with your doctor and parents.
