Q: What is Finasteride?

Finasteride belongs to a class of drugs known as 5-alpha reductase inhibitors . It functions by blocking the action of an enzyme that converts testosterone into dihydrotestosterone (DHT) . By reducing the levels of this hormone, the medication helps address the biological processes that affect hormone-sensitive tissues, such as the prostate and hair follicles. This mechanism is intended to manage the physical changes associated with these areas.

Q: What is Finasteride used for?

Finasteride is used to treat benign prostatic hyperplasia and androgenetic alopecia .

Q: How does Finasteride work?

Mechanism of Action Finasteride belongs to a class of medications known as 5-alpha reductase inhibitors. It works by interfering with the way the body processes testosterone. Specifically, it blocks an enzyme called 5-alpha reductase, which is responsible for converting testosterone into a more potent hormone called dihydrotestosterone (DHT). Effects on the Prostate In the prostate gland, DHT is a primary driver of tissue growth. When a person has benign prostatic hyperplasia (BPH), the prostate becomes enlarged, which can squeeze the urethra and make urination difficult. By lowering the levels of DHT in the blood and the prostate tissue, finasteride helps the prostate gland shrink over time. This reduction in size helps improve urine flow and reduces other symptoms associated with BPH. Effects on Hair Loss For men with male pattern hair loss (androgenetic alopecia), DHT contributes to the shrinking of hair follicles on the scalp. This process eventually leads to thinner hair and hair loss. Finasteride works by significantly lowering the levels of DHT in the scalp, which helps to: Slow down the progression of hair loss. Increase the amount of hair on the scalp. Promote hair regrowth in some individuals. Finasteride only works to manage these conditions as long as the medication is taken. If treatment is discontinued, DHT levels will return to their previous state, and the prostate may begin to grow again or hair loss may resume.

Question 11

What is the FDA approval status of Finasteride?

Accepted Answer

The U.S. Food and Drug Administration (FDA) has approved finasteride for two specific conditions in adult men:

Benign prostatic hyperplasia (BPH): To improve symptoms of an enlarged prostate and reduce the risk of urinary blockage or the need for surgery.
Male pattern hair loss (androgenetic alopecia): To increase hair growth and prevent further hair loss on the scalp.

The FDA has updated the safety labeling for finasteride to include several important warnings:

Pregnancy Risks: Finasteride is strictly contraindicated in women who are or may become pregnant. The medication can cause abnormalities in the external genitalia of a male fetus. Pregnant women should not handle crushed or broken tablets because the drug can be absorbed through the skin.
High-Grade Prostate Cancer: While finasteride may lower the overall risk of prostate cancer, clinical data indicates it may increase the risk of developing high-grade prostate cancer, which is a more aggressive form of the disease.
Post-Marketing Reports: The FDA has monitored reports of persistent sexual dysfunction, depression, and suicidal ideation in patients taking finasteride. Labeling has been updated to reflect these potential risks, which may persist after the drug is discontinued.

The FDA has issued alerts regarding compounded versions of finasteride. These products are not FDA-approved, and the agency has not reviewed them for safety, effectiveness, or quality. Consumers are advised to be aware of the risks associated with using medications that have not undergone the standard regulatory review process.

Question 12

What should I know about Finasteride and hair loss?

Accepted Answer

How Finasteride Works for Hair Loss

Finasteride is used to treat male pattern hair loss, also known as androgenetic alopecia. This condition typically involves a gradual thinning of the hair on the scalp, which can lead to a receding hairline or balding on the top of the head. The medication works by blocking the body's production of dihydrotestosterone (DHT), a male hormone that causes hair follicles to shrink and eventually stop producing hair.

Expectations and Results

When used for hair loss, finasteride is generally taken as a low-dose daily tablet. It is important to have realistic expectations regarding the timeline and duration of treatment:

Timeline for results: It usually takes at least three months of daily use before any improvement in hair growth or a reduction in hair loss is visible.
Long-term commitment: The medication must be taken continuously to maintain results. If you stop taking finasteride, the hair that grew back during treatment will likely be lost within 12 months.
Effectiveness: While it can help regrow hair, it is most effective at treating hair loss at the crown (the top of the head) and the middle of the scalp.

Safety and Restrictions

Finasteride is intended for use by adult men only. It is not approved for use in women or children. There are specific safety precautions regarding pregnancy: women who are pregnant or may become pregnant should not handle crushed or broken tablets. The medication can be absorbed through the skin and may cause birth defects in a male fetus.
