Finasteride

Finasteride

Finasteride is a prescription medicine used to treat male pattern hair loss (androgenetic alopecia) and benign prostatic hyperplasia (BPH) in men. It works by lowering levels of dihydrotestosterone (DHT), a hormone linked to hair follicle shrinkage and prostate growth. By reducing DHT, Finasteride helps slow hair thinning, support hair regrowth in some men, and improve urinary symptoms caused by an enlarged prostate when used as directed.

What is Finasteride used for?

Finasteride is a prescription medicine used to treat male pattern hair loss (androgenetic alopecia) and benign prostatic hyperplasia (BPH) in men. It works by lowering levels of dihydrotestosterone (DHT), a hormone linked to hair follicle shrinkage and prostate growth. By reducing DHT, Finasteride helps slow hair thinning, support hair regrowth in some men, and improve urinary symptoms caused by an enlarged prostate when used as directed.

How to take Finasteride?

Finasteride tablets are taken by mouth, usually once daily, with or without food. Swallow the tablet whole with water. Take it at the same time each day for consistent results. Do not crush or split the tablet. For hair loss, regular daily use is essential; stopping treatment can reverse benefits over time. Always follow the dose prescribed by a healthcare professional and avoid changing the dose without medical advice.

Side effects

Common side effects of Finasteride include reduced libido, erectile dysfunction, and decreased semen volume. These effects are usually mild and may improve with continued use or after stopping the medication. Less common effects include breast tenderness or enlargement and mood changes. Serious side effects are rare but should be reported immediately. If side effects persist or worsen, consult a healthcare provider for evaluation and guidance.

Drug interactions

Finasteride has few known drug interactions and is generally safe to use with most medications. However, inform your doctor about all prescription drugs, over-the-counter medicines, and supplements you take. This is especially important if you are being treated for prostate conditions or hormonal disorders. Avoid combining treatments without guidance, as individual medical history can affect safety and effectiveness.

Warnings

Finasteride is for use in men only and should not be handled by pregnant women, especially crushed or broken tablets, due to the risk of harm to a male fetus. It is not recommended for children. Men with liver disease should use caution. Finasteride can lower PSA levels, which may affect prostate cancer screening. Regular medical follow-up is advised during long-term use.

Storage

Store Finasteride tablets at room temperature, away from heat, moisture, and direct sunlight. Keep the medication in its original packaging and out of reach of children. Do not use expired tablets. Dispose of unused medicine safely according to pharmacy or local guidelines. Proper storage helps maintain the medicine’s effectiveness and reduces the risk of accidental exposure.

FAQ's

What does Finasteride do?

Finasteride blocks the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). Lower DHT levels help slow hair loss on the scalp and reduce prostate size in men with BPH. This hormonal action supports hair retention and improves urinary flow when taken consistently as prescribed.

How long does Finasteride take to work?

For hair loss, Finasteride usually takes 3 to 6 months to show visible results. Some men may notice reduced hair shedding earlier. Full benefits can take up to 12 months. For prostate symptoms, improvement may be seen within a few months. Continuous daily use is required to maintain results.

Does Finasteride increase testosterone?

Finasteride does not significantly increase total testosterone levels. It reduces DHT, which may cause a small rise in circulating testosterone, but this increase typically remains within the normal range. The clinical effect is primarily due to lowering DHT rather than boosting testosterone.

Can Finasteride regrow hair?

Finasteride can help regrow hair in some men, particularly at the crown and mid-scalp areas. Results vary by individual and stage of hair loss. It is more effective at slowing further loss than restoring advanced baldness. Best results are seen with early and consistent treatment.

How long does it take to see before and after results with Finasteride?

Before-and-after results are usually noticeable after 6 to 12 months of continuous use. Early signs include reduced shedding and thicker-looking hair. Stopping Finasteride typically leads to loss of gained hair within several months, so long-term use is needed to maintain results.
