Topical Finasteride

Safety Information

Before you start using finasteride and each time you get a refill, please review this important safety information. This information may be updated. It does not replace discussing your medical condition or treatment with your doctor or healthcare provider.

What is the FDA approved use of finasteride?

• Finasteride is FDA-approved as an oral medication to treat benign prostatic hyperplasia (Proscar) and androgenetic alopecia (Propecia) in men.
• Finasteride has not been FDA-approved for topical use in men or women. However, it may be prescribed off-label in topical compounded formulations to treat hair loss. Please note that oral finasteride has also not been approved for use in women, for any indication.

What is topical finasteride?

Topical finasteride is a compounded prescription medication that may be used for the treatment of male and female pattern hair loss (androgenetic alopecia). This compounded treatment is not approved by the FDA and is only available if prescribed after an online consultation with a licensed physician through the XYON Health platform.

Data from small scale and case studies suggests that topical finasteride may be an effective treatment for hair loss, with a potentially lower risk of side effects compared to the oral medication as a result of reduced systemic absorption.

What should I tell my healthcare provider before taking finasteride?

Please inform your doctor or healthcare provider if any of the following apply:

• You have a personal or family history of prostate cancer, breast cancer
• You have prostate or urinary symptoms such as reduced urine flow, difficulty urinating or pain
• You have a history of any serious mental health conditions
• You are pregnant, trying to get pregnant, or are breastfeeding

Who should not take finasteride?

You should not take finasteride if you:

• Have ever had an allergic reaction to finasteride or any other ingredients in the treatment
• Finasteride should not be used by women who are pregnant, may be pregnant or are breastfeeding
• Finasteride should not be used by infants or children

What are the possible side effects of finasteride?

The following side effects have been reported with finasteride use:

• Breast tenderness and enlargement. You should inform your doctor or healthcare provider if you notice any breast lumps, pain or nipple discharge
• Depression, anxiety, brain fog, suicidal ideation
• Decreased libido (sex drive)
• Allergic reactions (e.g., rash, itching, hives and swelling of the lips, tongue, throat, and face)
• Problems with ejaculation
• Testicular pain
• Erectile dysfunction (difficulty achieving or maintaining an erection)
• Male infertility and/or poor semen quality
  

Please note that finasteride has only been formally studied in male patients, so the side effect profile above is specific to clinical studies in men. Preliminary data on the use of finasteride in female patients has shown the following possible side effects:

• Decreased libido (sex drive)
• Breast tenderness and enlargement
• Mood changes (e.g., depression)
• Fatigue
• Muscle soreness
• Weight gain

There is some evidence that finasteride can increase the risk of some breast and prostate cancers.

When used off label in a topical form, systemic side effects of finasteride are expected to be less frequent/severe. The following is a list of possible side effects associated with the use of topical finasteride:

• Itching
• Irritation
• Dry and flaky scalp
• Increased scalp oiliness

The above lists do not represent all potential side effects, medication interactions or study data relating to the safety of finasteride. It is important to talk to your doctor, healthcare provider and/or pharmacist if you are experiencing any side effects. A comprehensive review of the potential safety risks of using finasteride can be found at this link: https://pubmed.ncbi.nlm.nih.gov/27672412/.

Safety Information

Before you start using finasteride and minoxidil and each time you get a refill, please review this important safety information. This information may be updated. It does not replace discussing your medical condition or treatment with your doctor or healthcare provider. Safety information for both finasteride and minoxidil is contained within this document. Please take care to review this entire document.

What is the FDA approved use of finasteride?

• Finasteride is FDA-approved as an oral medication to treat benign prostatic hyperplasia (Proscar) and androgenetic alopecia (Propecia) in men.
• Finasteride has not been FDA-approved for topical use in men or women. However, it may be prescribed off-label in topical compounded formulations to treat hair loss. Please note that oral finasteride has also not been approved for use in women, for any indication.

What is the FDA approved use of minoxidil?

• Topical minoxidil is FDA approved at concentrations of 2% and 5% as topical formulations to treat hair loss in women and men (Rogaine®). All other topical compounded strengths of minoxidil are considered off-label uses.
• Oral minoxidil is FDA-approved for the treatment of symptomatic high blood pressure. Low-dose oral minoxidil may be prescribed off-label to treat hair loss.

What is topical finasteride and minoxidil?

Topical finasteride and minoxidil is a compounded prescription medication used for the treatment of male and female pattern hair loss (androgenetic alopecia). This compounded treatment is not approved by the FDA and is only available if prescribed after an online consultation with a licensed physician through the XYON Health platform.

Data from small scale and case studies suggests that taking finasteride in combination with minoxidil may increase the effectiveness of hair loss treatment in some patients. This may be due to different mechanisms of action that help address the various causes of pattern hair loss.

What should I tell my healthcare provider before taking finasteride and minoxidil?

Please inform your doctor or healthcare provider if any of the following apply:

• You have a personal or family history of prostate cancer, breast cancer
• You have prostate or urinary symptoms such as reduced urine flow, difficulty urinating or pain
• You have a history of heart conditions (e.g., high blood pressure, heart failure, previous heart attack, pericarditis, abnormal heart rhythm, chest pain/angina)
• You have a history of vascular conditions (e.g., stroke, severe lower leg swelling, pulmonary hypertension)
• You have a history of liver or kidney disease or dysfunction
• You have a history of any serious mental health conditions
• You are pregnant, trying to get pregnant, or are breastfeeding

You should be aware that minoxidil has the potential to be toxic to some animals. Please ensure that pets do not come into contact with minoxidil or lick your hands after application.

Who should not take finasteride and minoxidil?

You should not take finasteride and minoxidil if you: 

• Have ever had an allergic reaction to finasteride, minoxidil or any other ingredients in the treatment
• Have a history of liver disease or dysfunction
• Finasteride and minoxidil should not be used by women who are pregnant, may be pregnant or are breastfeeding
• Finasteride and minoxidil should not be used by infants or children

Black box warning: Serious cardiac effects associated with oral minoxidil

• Oral minoxidil has a black box warning because the medication is a powerful antihypertensive agent. Serious cardiovascular side effects have been observed in clinical trials where the drug has been used to treat symptomatic high blood pressure. When used off-label for hair loss, oral minoxidil is typically dosed at less than 5mg to help reduce the likelihood of experiencing an adverse cardiovascular event
• Oral minoxidil can cause pericardial effusion, which can progress to a condition called tamponade which increases pressure on the heart and keeps it from beating properly. This can result in sharp chest pain and difficulty breathing. Seek emergency treatment if this occurs
• Chest pain warning: Minoxidil can increase your heart rate and cause or worsen chest pain. If you have new or worsening pain in the chest, arm, or shoulders, tell your doctor right away or go to the nearest emergency department.
• Heart function warning: Minoxidil can cause poor heart function or worsen existing heart problems like heart failure. When tested on animals, minoxidil caused several kinds of lesions of the heart muscle as well as other adverse heart effects. Patients with malignant hypertension and those already receiving guanethidine should be hospitalized when minoxidil is first administered so that they can be monitored to avoid too rapid or large decreases in blood pressure

What are the possible side effects of finasteride and minoxidil?

The following side effects have been reported with finasteride use:

• Breast tenderness and enlargement. You should inform your doctor or healthcare provider if you notice any breast lumps, pain or nipple discharge
