Takeaways

• 😀 Finasteride has been used for over 20 years to treat male pattern hair loss and prostate enlargement.
• 😀 The main function of finasteride is to block an enzyme that converts testosterone into DHT, which is a key factor in hair loss.
• 😀 The drug does not significantly alter overall hormone levels but reduces DHT, which in turn helps stabilize hair loss.
• 😀 Many fears surrounding finasteride side effects are fueled by myths on the internet, but in practice, side effects are rare when taken at the correct dose.
• 😀 The recommended dose for hair loss is 1 mg per day, but a lower frequency (e.g., 3 times a week) can still be effective without increasing the risk of side effects.
• 😀 A lower dose reduces the likelihood of sexual side effects like reduced libido or difficulty maintaining erections, which occur in a small percentage of users.
• 😀 The drug lasts for at least 30 days in the system, so daily use is not necessary to maintain effectiveness.
• 😀 In clinical trials, the incidence of sexual side effects in finasteride users was low, with some reporting similar issues while on a placebo.
• 😀 Most side effects are reversible once the medication is stopped, with some patients experiencing recovery in as little as two weeks.
• 😀 For patients who experience delayed side effects, reducing the dose or taking breaks can help manage the issues without halting treatment altogether.

Q & A

What is the primary action of finasteride in treating hair loss?

Finasteride works by blocking the enzyme that converts testosterone into dihydrotestosterone (DHT). By reducing DHT levels, it helps to stabilize hair loss in men with male pattern baldness.

Why did finasteride originally come into use for treating hair loss?

Finasteride was initially developed to treat prostate enlargement, and it was an unexpected discovery that it also helped reverse or stabilize hair loss in men with enlarged prostates.

What is the recommended dose of finasteride for hair loss treatment?

The recommended dose for treating hair loss is 1 mg per day, which is sufficient for most patients to reduce DHT levels effectively.

Why do the doctors suggest a reduced frequency of finasteride administration, like taking it three times a week?

The doctors suggest that finasteride lasts for about 30 days in the body, meaning it is not necessary to take it every day. Taking it less frequently, such as three times a week, can still maintain its effectiveness while reducing the likelihood of side effects.

What are some common side effects associated with finasteride?

Common side effects include reduced libido and difficulty maintaining erections, especially when taking higher doses like 5 mg. However, these side effects are rare and often reversible when the medication is stopped.

How do side effects manifest in patients using finasteride?

Some patients experience immediate side effects within the first two weeks, while others may experience delayed side effects months into treatment. Side effects are typically related to the dose and frequency of the medication.

Can stopping finasteride for a short period affect hair loss?

No, taking a break from finasteride for a short period (like one or two months) will not lead to significant hair loss or reversal of the progress made. The medication stays in the system for a while, so temporary cessation won't harm long-term results.

What is the relationship between psychological expectations and side effects of finasteride?

Psychological factors can play a significant role in experiencing side effects. If a patient expects side effects due to negative information or fear, they may be more likely to perceive them, even when they are rare or mild.

How do the doctors manage patients who experience side effects from finasteride?

The doctors adjust the dose or frequency of finasteride, often reducing it to a lower level or allowing a break to help mitigate side effects. They have found that most patients can tolerate a customized dosage regimen without experiencing significant issues.

What should patients do if they experience side effects from finasteride?

If side effects occur, patients should stop taking finasteride, and the side effects will typically resolve within weeks. If side effects are delayed, reducing the dose or taking breaks can help resolve the issues while maintaining the effectiveness of the treatment.
