Also, on 6/9/2011, FDA released a drug safety communication detailing the long term side effects of finasteride and it is referenced here at the following link: https://www.pdr.net/fda-drug-safety-communication/propecia?druglabelid=378&id=8965

Finasteride & PSA (Prostate Specific Antigen): PSA test is a screening blood test performed by your physician to check for prostate cancer. Finasteride has been shown to reduce the PSA level, sometimes as much as 50%. The significance of this is as follows. Reduction in PSA can mask underlying prostate cancer. When you have a PSA test done, it is imperative that you tell your physician that you are taking finasteride in order to better assess the real PSA value of your blood test. Any changes from your baseline PSA can indicate a possible prostate cancer, even if your levels are within normal limits. You should always tell your physician if you are or are not taking finasteride, as this will impact the actual interpretation of your PSA level.  

The American Academy of Family Physicians and the Canadian Task Force on Preventive Health Care reThe American Academy of Family Physicians and the Canadian Task Force on Preventive Health Care recommend against PSA-based screening for prostate cancer. The American College of Physicians recommends that clinicians discuss the benefits and harms of screening with men aged 50 to 69 years and only recommends screening for men who prioritize screening and have a life expectancy of more than 10 to 15 years. The American Urological Association recommends that men aged 55 to 69 years with a life expectancy of more than 10 to 15 years be informed of the benefits and harms of screening and engage in shared decision making with their clinicians, taking into account each man’s values and preferences. It notes that to reduce the harms of screening, the screening interval should be 2 or more years. The American Urological Association also notes that decisions about screening, including potentially starting screening before age 55 years, should be individual ones for African American men and men with a family history of prostate cancer. The American Cancer Society adopted detailed screening recommendations in 2016 that highlight the importance of shared decision making and the need for informed discussion of the uncertainties, risks, and potential benefits of screening. It recommends conversations about screening beginning at age 50 years and earlier for African American men and men with a father or brother with a history of prostate cancer before age 65 years. 

Finasteride can have rare and uncommon side effects that you should be aware of. This includes sexual side effects (such as decrease libido, erectile dysfunction), psychological side effects (such as depression, mood instability, or anxiety) and post-finasteride syndrome. If these side effects do occur, even if mild, please report them to your doctor immediately and stop taking the medication.  There is an increased risk of the more advanced stage of (high grade) prostate cancer or serious prostate cancer. In rare cases, male breast cancer has also been reported.  

PREGNANCY WARNING: Finasteride is for use by MEN ONLY and should NOT be used by women or children. Patients should not use finasteride if your spouse is planning to get pregnant, is pregnant or breastfeeding. Patients should wash their hands with soap and water every time after the application of the topical finasteride solution. Females who are pregnant or who may become pregnant or planning on becoming pregnant or breastfeeding should not come in contact with finasteride. Finasteride may harm your unborn baby. If a woman who is pregnant comes in contact with finasteride solution, please wash the area right away with soap and water and contact your  healthcare provider. If a pregnant woman with a male baby fetus swallows or comes in contact with finasteride, the male baby may be born with sex organs that are not normal.

You should not donate blood while taking finasteride because if given to pregnant females, it could harm unborn fetuses. Please wait at least 1 month after you stop taking finasteride to donate blood.

Pericardial effusion, heart failure, cardiac tamponade, pericarditis, Stevens-Johnson syndrome, allergic reaction, swelling of extremities, edema, peripheral edema , sodium retention, hypotension, angina, sinus tachycardia, leukopenia, thrombocytopenia, bullous rash, contact dermatitis, erythema, mastalgia, headache, hypertrichosis, pruritus, xerosis, vomiting, nausea, irritation, flakiness, itch, tingling and burning.

If applied with fingertips, wash hands thoroughly after applying. If the metered-spray applicator is used, avoid inhalation of the mist. Minoxidil is classified as pregnancy risk category C. Although no adequate human studies have examined the effects of this drug on the fetus, animal reproduction studies have shown adverse effects, including reduced ability to conceive and a reduced survival of offspring. Dysmorphic facial features and hypertrichosis were observed in an infant whose mother took oral minoxidil during pregnancy. According to the manufacturer, minoxidil should not be administered to a nursing mother. Skin abrasion or irritations, such as excoriations, psoriasis, or sunburn, can increase the systemic absorption of topically administered minoxidil.
