What is finasteride?

Finasteride belongs to a class of drugs called 5-alpha reductase inhibitors. It lowers the concentration of a hormone called DHT within the scalp, which is widely considered the leading cause of hair loss in men.*

Using topical finasteride safely

The risk of experiencing adverse drug reactions to topical finasteride is typically lower than the risk associated with oral treatment.* That said, there is always a risk that you may experience reactions.

Speak with your dermatologist if you are concerned about the side effects of finasteride or experience any side effects after starting topical finasteride.

Wash your hands thoroughly after applying your medication. Avoid touching your scalp and/or washing your hair directly after each application. Do not attempt to adjust the prescribed dosage or stop using this medication without consulting a physician. If you miss a dose, apply your medication as soon as you are able to on the same day.

Return any unused medication to the dispensing pharmacy or locate a drug take-back program near you.

Side effects (TOPICAL)

Clinical studies have demonstrated that the risk of experiencing adverse drug reactions to topical finasteride is often lower than the risk associated with oral treatment. Most men do not experience serious or lasting side effects when using topical finasteride. However, this medication can cause adverse reactions in some individuals. Finasteride has been associated with sexual side effects including erectile dysfunction and decreased libido in some men. Additional adverse reactions may include: Changes in ejaculatory volume or difficulty ejaculating; male breast enlargement; changes in breast tissue or discharge from nipples; breast pain or tenderness; testicular pain or tenderness; pain or difficulty urinating; changes in mood; new or worsened symptoms of depression. Some individuals may experience an increase in hair loss (shedding) shortly after starting treatment with topical finasteride. In most cases, these side effects are temporary and subside within a few weeks of starting or discontinuing treatment. Certain individuals may continue to experience sexual side effects even after stopping the medication, although this is rare.

The following symptoms can indicate an allergic reaction to this drug formulation and may require medical attention: rash or skin irritation, tightness or pain in the chest, itching or swelling (especially of the face, tongue or throat), extreme dizziness, shortness of breath or difficulty breathing, increased heart rate or palpitations. Topical drug formulations in particular can cause skin irritation, redness and/or burning at the site of application. This is not a complete list of possible side effects; individual experiences will vary. If you notice other side effects not listed above, contact your doctor or pharmacist. In the US: Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088 or at It is important to report all adverse reactions that you believe to be associated with topical finasteride to the prescribing physician, even those not listed above.

Additional safety information and contraindications

(1) Considerations for women who are, or may become pregnant: Finasteride is a category X medication and must not be used during pregnancy. This drug can negatively impact the health of a developing fetus. Exposure to this drug has been tied to genital abnormalities in male infants. Women who are pregnant, breastfeeding or who may become pregnant should avoid handling this medication. Do not use topical finasteride if you are trying to conceive with a female partner.

(2) Drug interactions: There are no known drug interactions of clinical significance with finasteride. Disclose a complete list of medications and/or supplements you are taking prior to starting treatment with topical finasteride.

(3) Risk of high-grade prostate cancer: 5-alpha reductase inhibitors such as finasteride may increase the risk of developing high-grade prostate cancer in some men. Individuals with a history of prostate cancer should have their serum prostate-specific antigen (PSA) levels monitored by a physician while using topical finasteride.

(4) Blood donation: You should not donate blood while using topical finasteride. It is recommended that you refrain from donating blood for at least 1 month following your final dose of topical finasteride.

Not all topical finasteride formulations are created equal. Topical finasteride is a compounded medication. Various formulations contain different concentrations of the active ingredient in different mediums.

XYON’s proprietary SiloxysSystem™ gel technology is a compounding medium that can be mixed with finasteride at a concentration of up to 2.5%. This precision topical formulation delivers the active ingredient to the hair follicles in a controlled way.

Most men can expect to see evidence of hair regrowth around 6 months after starting a treatment regimen. Some individuals notice improvements in hair quality within 3-4 months.

Once you have started using topical finasteride, it will take time for hair follicles to transition back into the active growth stage. To ensure the best results, it’s important you follow the application schedule recommended by the prescribing physician.

Within a few months of starting treatment, you may notice hair loss. This is a sign that the medication is working and can be expected shortly after you begin using topical finasteride.

The type of temporary hair loss associated with finasteride is called shedding. It indicates that old hairs are being pushed out of the follicle to make room for new growth.
