I am a female, aged 68 years. My doctor just put me on finasteride 5mg daily. Is it now safe for women? And is the dosage too high? If I cut the pill into fourths, would that still be too much?
I would ask this question and your concerns with your doctor. If you need a second opinion, you need then see another doctor.
Please understand this from a medical perspective and I’m not just trying to brush you off. You provided your gender and your age, but I cannot advise you with just that information. For example, is there a breast, ovarian, or cervical cancer history in your family or have you had one of these cancers in the past? There are many variables, so that is the role your doctor plays in these decisions.
Finasteride is not FDA approved for treating female hair loss (I assume that is why you were prescribed it), which means that your doctor prescribed it to you off-label and you need to ask him/her about this. For men, 1mg is recommended for treating hair loss and 5mg is for treating the prostate… so it is unusual for a doctor to prescribe 5mg finasteride for treating female hair loss.

This is the first FDA safety probe relating to either Propecia (finasteride) or Avodart (dutasteride) that I’m aware of, and it is looking into a link between male breast cancer and 5-alpha reductase inhibitors. Any FDA probe certainly is in the best interest of the public, but as the article points out, “Merck spokeswoman Pam Eisele said the prescribing instructions for Proscar and Propecia already mention cases of male breast cancer seen in clinical trials.” No relationship has been established though, so we’ll have to wait to see what is discovered in the FDA’s investigation.
