Finasteride Side Effects: Full Disclosure And Notice To Users
Read this section before you start taking Finasteride and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment. Finasteride has been FDA approved for use in men for androgenetic alopecia in the oral form; all other formulations are off-label.
For full transparency, side effects of Finasteride include but not limited to redness, irritation, burning sensation, contact dermatitis, dry, & flaky scalp, hypersensitivity reaction (allergic reaction), angioedema, prostate cancer (high-grade), breast cancer, male infertility, impotence, loss in sexual ability, sexual desire, sexual drive, or performance, hypotension, tenderness in genital organs, testicular pain or numbness, infertility, poor seminal quality, poor sperm mobility, penile curvature changes, gynecomastia (enlarge breast tissue), swelling tingling burning or pain in your face, throat hands or feet, swelling or tenderness in your breasts, lump under the arms or in the breast area, hair loss (temporary or permanent), change in shape of penis, weakness, headache, confusion, brain fog, fogginess of the head, short-term and long-term memory loss, terrible fatigue, trouble concentrating, increasingly moody, depression, mood swings, mood changes, runny nose, sleepiness or unusual drowsiness, slurred speech, sneezing, stuffy nose, abdominal/stomach pain, back pain, decreased amount of semen, diarrhea, hives or welts, itchy skin, redness of the skin, skin rash, death, swelling of the lips and face, tingling of the hands or feet, breast cancer in males and females, any other cancer in males and females, lower testosterone, complete loss of testosterone, shrinkage of sexual organs, change in sexual orientation and any side effect contributed to what is now called post-finasteride syndrome and listed on the website: www.pfsfoundation.org/about-pfs-post-finasteride-syndrome/. All sexual side effects may be long-term (permanent).
If you develop any of the following side effects, please stop using Finasteride and contact your healthcare provider right away: chest pain, rapid heartbeat, faintness or dizziness, sudden & unexplained weight gain or loss, swelling of hands or feet, breast tenderness/enlargement, unwanted facial hair growth, sexual dysfunction (e.g., low libido, erectile dysfunction, decreased volume of ejaculate), symptoms of depression, no scalp hair regrowth after 6 months of use, and severe scalp irritation. These are not all of the possible side effects of topical finasteride. Call your healthcare provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Patients must not share the medication with any female. Finasteride is not FDA approved for use in women, but may be used off-label to treat hair loss in women over 50 in some circumstances. Finasteride is a Category X (teratogenic) medication due to its potential to cause birth defects in male fetuses. Pregnant women, children, individuals who are breastfeeding, individuals who have the potential to become pregnant, or children should not use or come into direct skin contact with Finasteride, handle this medication, or come into contact with the treatment site (your scalp) after the medication has been applied. If they do, they should immediately clean the site of contact on their skin with soap and water.
The effectiveness of Finasteride for hair loss in women as well as the potential risks/side effects are not well understood because large scale clinical trials have not been done in this population. When used off-label to treat hair loss in women, small studies have indicated that women experience similar side effects to men taking Finasteride (as listed above). Women may additionally experience dry skin, acne, headaches, irregular menses, increased body hair, headache, dizziness, fatigue, weight gain, elevated liver enzyme, edema. There have been reports of breast cancer in men who have taken oral Finasteride and it is unknown how this risk may translate to women.
The above is not a complete list of all side effects or studies conducted. User agrees and understands that there may also be other side effects that may occur that have not been reported, discovered, or listed in the literature yet and may have been reported but not listed here. This list is intended to give full transparency about the possibility of most or all of the side effects of Finasteride, some of which may be long term and permanent. User understands and agrees that they have been fully informed about the above side effects. Our goal is to empower our patients to make educated decisions about their treatment choices. We are incorporating the following drug PDR in this section as a reference: https://www.pdr.net/drug-summary/Propecia-finasteride-378.609. 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. In patients taking Finasteride, 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.
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 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.
Pregnancy Warning: Females who are pregnant or who may become pregnant should not come in contact with Finasteride. Finasteride may harm your unborn baby. If a woman who is pregnant or a child comes in contact with a Finasteride solution or crushed pills, 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. Finasteride may also affect sperm counts/quality and can be secreted in the sperm in very low amounts, but currently there are no recommendations based on data from clinical trials to suggest that men should avoid taking Finasteride during conception or while a partner is pregnant.
Dutasteride Side Effects: Full Disclosure And Notice To Users
Please read this section carefully before you start taking Dutasteride and each time you get a refill, as there may be new information.

For complete transparency, the side effects of Dutasteride include, but are not limited to, the following:
1. Allergic Reactions and Hypersensitivity: angioedema (swelling of the deeper layers of skin, often around the eyes and lips), rash, hives, itching, swelling of the face, throat, hands, or feet, erythema multiforme, and Stevens-Johnson syndrome (rare, severe skin reactions).
2. Sexual Side Effects (may be long-term or permanent): decreased libido (sexual drive), erectile dysfunction (impotence), abnormal ejaculation or decreased ejaculate volume, difficulty achieving orgasm, decreased sexual performance or desire, penile fibrosis or scarring, including changes in penile shape, gynecomastia (enlarged breast tissue in men), tenderness in genital organs, testicular pain or swelling, and testicular numbness, infertility, including reduced semen quality and poor sperm motility.
3. Psychological Side Effects: depression and anxiety, mood changes, irritability, and brain fog, cognitive effects, including short-term and long-term memory loss, fatigue and trouble concentrating.
4. Hormonal and Reproductive Effects: lowered testosterone levels, potentially leading to shrinkage of sexual organs, breast cancer (rare in men), lumps under the arms, or tenderness in breast tissue, fertility concerns: Dutasteride may affect sperm count, motility, and overall seminal quality.
5. Cardiovascular and Blood Pressure Effects: hypotension (low blood pressure), including orthostatic hypotension (sudden drop in blood pressure upon standing), heart failure, atrial fibrillation, and palpitations (rare), and syncope (fainting or feeling like you might pass out).
6. Dermatological and Hair Effects: hair loss (temporary or permanent), skin rash, redness, tingling, or itching, dwelling or tenderness in breasts, including gynecomastia, and dry skin or changes in skin texture.
7. Gastrointestinal Effects: abdominal or stomach pain, nausea, diarrhea, constipation, and weight changes (rapid or unexpected gain/loss).
8. Neurological Effects: dizziness, vertigo, and headache, confusion and cognitive impairment, sleep disturbances, such as insomnia or drowsiness.
9. Respiratory Effects: runny or stuffy nose, sneezing, sinusitis, cough, and pharyngitis (sore throat), and dyspnea (shortness of breath or difficulty breathing).
10. Rare and Serious Risks: high-grade prostate cancer or advanced prostate cancer, male breast cancer, visual impairment, floppy iris syndrome (complication during cataract surgery), priapism (persistent painful penile erection unrelated to sexual activity)—seek emergency help if erection lasts more than 4 hours, and liver function abnormalities (elevated liver enzymes).
Warnings and Special Precautions
Pregnancy Risk: Dutasteride is a Category X medication, meaning it can cause birth defects in male fetuses. Pregnant women and children should not use or handle Dutasteride. If exposed, wash the area with soap and water immediately and seek medical advice. Dutasteride may be found in semen in very low amounts. No clinical data suggests that men need to avoid use during conception or when a partner is pregnant, but risks should be discussed with your doctor.
Off-Label Use for Women: Dutasteride is not FDA-approved for use in women but may be used off-label for hair loss treatment. Women may experience side effects similar to men, including hormonal changes, acne, headaches, irregular menstrual cycles, increased body hair, and elevated liver enzymes.
Breast cancer risk is uncertain for women, and no large-scale clinical trials have assessed these risks.
Laboratory Monitoring: Prostate Specific Antigen (PSA) Monitoring: Dutasteride reduces PSA levels, potentially masking prostate cancer. Inform your doctor if you are taking Dutasteride for accurate PSA interpretation. Changes in PSA from your baseline should be closely monitored. Screening recommendations for prostate cancer vary, emphasizing the importance of shared decision-making with your healthcare provider.
Contraindications: Do not use if you have severe orthostatic hypotension, syncope, or vertigo. Not for use in neonates, infants, children, or adolescents under 18, as safety and effectiveness are not established. Caution is advised for patients with liver disease. Avoid handling if pregnant, breastfeeding, or trying to conceive.
Compounded Medications: Topical formulations of Dutasteride or compounded prescriptions are not FDA-approved. These include combinations with Minoxidil, Retinoic Acid, and/or Hydrocortisone.
Patient Responsibility: Inform your healthcare provider of all medications you are taking, especially if you experience side effects. Do not share Dutasteride with others, especially females.

Special Warnings and Precautions:
Liver Disease: Oral ketoconazole should not be used in individuals with pre-existing liver conditions or elevated liver enzymes. Regular monitoring is essential during treatment.
Heart Conditions: Avoid use in individuals with a history of arrhythmias, prolonged QT interval, or other heart conditions. Monitoring of ECG may be necessary.
Endocrine Disorders: Use with caution in individuals with adrenal insufficiency, pituitary disorders, or other endocrine abnormalities. Blood tests to monitor hormone levels may be required.
Drug Interactions: Ketoconazole has significant interactions with various medications. Inform your healthcare provider of all medications you are taking:
Antacids and Acid-Reducing Agents: Medications like proton pump inhibitors (e.g., omeprazole) or H2-receptor antagonists (e.g., ranitidine) can reduce the absorption of oral ketoconazole by increasing gastric pH. Space dosing or consider alternative antifungals.
CYP3A4 Inhibitors/Inducers: Ketoconazole is a strong CYP3A4 inhibitor. Drugs metabolized by this enzyme (e.g., statins, calcium channel blockers, certain antipsychotics) may have altered levels, increasing the risk of adverse effects or toxicity.
QT-Prolonging Drugs: Avoid concomitant use with medications that prolong the QT interval, such as certain antipsychotics, antiarrhythmics, and fluoroquinolones.
Warfarin: Increased risk of bleeding due to altered metabolism of warfarin.
Oral Contraceptives: Decreased efficacy of hormonal contraceptives may occur, necessitating additional birth control measures.
Pregnancy and Breastfeeding:
Topical Use: Generally considered safe during pregnancy and breastfeeding, but consult a healthcare provider before use.
Oral Use: Use with caution during pregnancy (Category C) due to potential teratogenicity. Oral ketoconazole should be avoided in breastfeeding due to potential harm to the infant.
Additional Information: For a detailed reference on Ketoconazole, consult the FDA Drug Label and the Prescriber’s Digital Reference (PDR).
