When it comes to treating hair loss, there are countless options available on the market. One popular medication that has gained widespread attention is finasteride. If you’re considering using this medication, then one of the first things you might be curious about is how long does finasteride last.
To give you the short answer, finasteride can have a lasting effect on hair growth for up to a year or more. However, the extent of the results can vary from person to person. Some individuals may see a significant increase in hair growth, while others may only notice a slight difference in hair density.
For those who are experiencing early stage male pattern baldness, finasteride can be a promising option. This medication works by reducing DHT levels in the scalp, which allows hair follicles to grow more easily and resist further shrinkage. Plus, with its lasting results, finasteride can provide a long-term solution for those looking to maintain a youthful head of hair.
Mechanism of action of finasteride
Finasteride is a medication that is commonly used for the treatment of benign prostatic hyperplasia (BPH) and androgenetic alopecia (AGA), also known as male pattern baldness. Finasteride belongs to a class of medications called 5-alpha-reductase inhibitors, which means that it works by inhibiting the activity of the enzyme 5-alpha-reductase. 5-alpha-reductase is responsible for converting testosterone, a male hormone, into dihydrotestosterone (DHT), a hormone that is closely associated with the development and progression of male pattern baldness and BPH.
By inhibiting the activity of 5-alpha-reductase, finasteride reduces the levels of DHT in the body, leading to a decrease in the size of the prostate gland in men with BPH and an increase in hair growth in men with male pattern baldness. Finasteride does not affect the levels of other hormones in the body, such as testosterone, luteinizing hormone, follicle-stimulating hormone, or estradiol.
Dosage and Administration of Finasteride
Finasteride is a prescription medication used to treat hair loss and enlarged prostate in men. Before taking the medication, it is important to understand the dosage and administration guidelines to ensure proper treatment.
The recommended dose of finasteride for hair loss is 1 mg once daily. It should be taken with or without food. For enlarged prostate, the recommended dose is 5 mg once daily.
- It is important to take finasteride regularly to see its effectiveness.
- The medication may take up to 3 months to see its effects.
- Finasteride should not be crushed or chewed.
Finasteride should be taken exactly as prescribed by a healthcare provider. It is important not to change the dosage or frequency of the medication without consulting with a doctor. It is also important to inform the doctor of any other medications or medical conditions prior to taking finasteride.
In terms of administration, finasteride is an oral medication that should be swallowed whole with a glass of water. The medication should be stored at room temperature and kept away from moisture, heat, and light.
| Dosage | Indication |
|---|---|
| 1 mg | Hair loss |
| 5 mg | Enlarged prostate |
It is important to follow the dosage and administration guidelines for finasteride to ensure proper treatment for hair loss or enlarged prostate. Consulting with a healthcare provider can also provide valuable insights and recommendations regarding the use of finasteride.
Duration of finasteride treatment for androgenetic alopecia
Finasteride, a medication used to treat androgenetic alopecia, also known as male pattern baldness, is known to be effective in promoting hair growth and preventing further hair loss. However, it is important to note that the duration of treatment can vary depending on several factors such as severity of hair loss, response to treatment, and personal preferences.
- Minimum duration: According to clinical studies, it takes around 3-6 months for patients to start seeing visible results from using finasteride. Therefore, the minimum recommended duration for treatment is at least 6 months to see the full effect of the medication.
- Recommended duration: As per the FDA, the recommended duration of finasteride treatment for androgenetic alopecia is at least 12 months. This is based on studies that have shown significant improvement in hair growth for patients who have been on finasteride for at least one year.
- Long-term treatment: While there is no specified maximum duration for finasteride treatment, long-term use has been known to provide sustained improvement in hair growth and thickness. Many patients continue to take finasteride for years to maintain their hair growth.
It is important to note that the effectiveness of finasteride may diminish over time, and some patients may experience a decreased response after several years of use. Therefore, it is recommended to regularly consult with a healthcare provider to adjust treatment duration and assess if the medication is working effectively.
Below is a table summarizing the recommended duration of finasteride treatment:
| Duration | Effectiveness |
|---|---|
| 6 months | Visible improvement |
| 12 months | Significant improvement |
| Long-term | Sustained improvement |
It is always best to consult with a healthcare provider to determine the appropriate duration of finasteride treatment based on individual needs and preferences.
How long it takes for finasteride to show results
Finasteride is a popular medication used to treat male-pattern baldness and other conditions related to hair loss. It works by blocking an enzyme that converts testosterone into dihydrotestosterone (DHT), which is responsible for hair loss in men.
Many patients wonder how long they should take finasteride before seeing results. Here are some key points to keep in mind:
- Finasteride typically takes 3-6 months to start showing visible results. During this period, patients may experience shedding as old hairs fall out to make way for new ones.
- Most patients will see significant hair growth after 6-12 months of continuous treatment. However, results may vary depending on the severity of the patient’s hair loss and their individual response to the medication.
- It is important to note that finasteride must be taken continuously to maintain its effects. If treatment is stopped, any hair that was gained will be lost within a year.
To get the most out of finasteride treatment, it is important to follow the prescribed dosing regimen and to be patient in waiting for results.
Common side effects of finasteride
- Decreased sex drive
- Erectile dysfunction
- Decreased semen volume
- Breast tenderness or enlargement
When to contact a healthcare provider
If you experience any of the following symptoms while taking finasteride, contact your healthcare provider immediately:
- Chest pain
- Dizziness or fainting
- Allergic reaction (difficulty breathing, hives, swelling of the face or throat)
Finasteride dosing and administration
Finasteride is available in tablet form and is typically taken by mouth once a day with or without food. The recommended dose for treating hair loss is 1 mg daily, although some patients may be prescribed a higher dose for other conditions.
| Condition | Dosage |
|---|---|
| Male-pattern baldness | 1 mg daily |
| Benign prostatic hyperplasia (BPH) | 5 mg daily |
It is important to take finasteride as prescribed and to follow up with your healthcare provider regularly to monitor your progress and adjust your dosage if necessary.
Finasteride’s Effect on Hair Growth Cycle
Finasteride is a medication that is commonly used to treat male pattern baldness. It works by inhibiting the conversion of testosterone to dihydrotestosterone (DHT). DHT is a hormone that is responsible for the miniaturization of hair follicles, which leads to hair thinning and eventual hair loss in men.
When taken regularly, finasteride can significantly slow down the hair loss process and even promote new hair growth. But how exactly does it affect the hair growth cycle?
- Anagen Phase: The anagen phase, also known as the growth phase, is when hair actively grows from the follicle. Finasteride extends the anagen phase by up to 3 years, allowing hair to grow longer and thicker.
- Catagen Phase: The catagen phase is a transitional phase where hair stops growing and prepares to shed. Finasteride does not have any significant effect on this phase.
- Telogen Phase: The telogen phase is the resting phase where hair is shed from the follicle. Finasteride can delay the onset of the telogen phase, which means that fewer hairs will be shed at once, resulting in a fuller appearance.
In addition to affecting the length of the anagen phase, finasteride can also increase the diameter of individual hair strands. This means that the new hair that grows in is thicker and fuller than before, further enhancing the overall appearance of the hair.
It’s important to note that finasteride typically takes at least 3 months to start working, and results may take up to a year to become fully visible. It’s also important to continue taking the medication as directed, as stopping can result in a reversal of the effects.
| Phase | Duration (approx.) | Effect of Finasteride |
|---|---|---|
| Anagen | 2-7 years | Extends phase by up to 3 years, promotes thicker hair growth |
| Catagen | 2-4 weeks | No significant effect |
| Telogen | 2-4 months | Delays onset, resulting in fuller appearance |
Overall, finasteride’s effect on the hair growth cycle can lead to thicker, fuller-looking hair that is less prone to shedding. By understanding how the medication works, users can have a better understanding of what to expect and how to achieve the best results.
Side Effects of Finasteride
While finasteride is typically a well-tolerated medication, like any medication, it can cause side effects. Some of the most commonly reported side effects of finasteride include:
- Reduced sex drive
- Erectile dysfunction

| Decreased volume of ejaculate | 1.8% |
| Gynecomastia | 0.5% |
| Rash or itching | 0.3% |
| Dizziness | 0.3% |
While these numbers indicate that side effects from finasteride use are relatively rare, it’s still important to be aware of the potential risks and to speak with your doctor about any concerns you may have.
Finasteride’s Efficacy in Treating Benign Prostatic Hyperplasia (BPH)
Benign prostatic hyperplasia (BPH) is a common condition where the prostate gland grows larger than its normal size, causing urinary problems. Finasteride belongs to a class of drugs known as 5-alpha reductase inhibitors and it is commonly used to treat BPH.
- Finasteride reduces the size of the prostate gland, thus relieving urinary symptoms associated with BPH.
- Clinical studies have shown that finasteride can improve urinary flow rate and reduce the need for surgery in men with BPH.
- Finasteride is an effective treatment option for BPH and it has been approved by the FDA for this purpose.
One of the reasons why finasteride is effective in treating BPH is because it targets the root cause of the condition – the excessive growth of the prostate gland. By reducing the size of the gland, finasteride helps to relieve urinary symptoms such as frequent urination, weak urine flow, and the need to urinate urgently.
While finasteride is an effective treatment for BPH, it is important to note that it may take some time for the drug to start working. Patients may experience some improvement in their symptoms within a few weeks, but it may take up to six months for the full effect of the drug to be realized.
Patients who take finasteride for BPH should also be aware of the potential side effects of the drug. Finasteride may cause sexual side effects such as decreased libido, erectile dysfunction, and ejaculation disorders. However, these side effects are usually reversible and will go away once the patient stops taking the drug.
In conclusion, finasteride is an effective treatment option for BPH. It works by reducing the size of the prostate gland, which helps to relieve urinary symptoms associated with the condition. While it may take some time for the drug to start working, patients who take finasteride for BPH can expect to see a significant improvement in their symptoms over time.
Long-term safety of finasteride
Finasteride is a medication used for treating hair loss and an enlarged prostate. It works by blocking the production of a hormone called dihydrotestosterone (DHT) in the body. DHT is responsible for hair loss and prostate growth. By inhibiting DHT, finasteride stops hair loss in men and reduces the size of the prostate gland. However, there have been concerns about the safety of this medication in the long-term. Here’s what you need to know about the long-term safety of finasteride.
- Sexual side effects: One of the most common side effects of finasteride is a decrease in libido and sexual dysfunction. While these side effects are usually reversible when the medication is stopped, some men have reported persistent sexual side effects even after they stop taking finasteride. The risk of sexual side effects appears to be higher in older men and those who take the medication for a long time.
- Breast cancer: There have been some reports linking the long-term use of finasteride with an increased risk of breast cancer in men. However, the evidence is not conclusive, and more research is needed to confirm this link.
- Depression and anxiety: Some studies have suggested that long-term use of finasteride may increase the risk of depression and anxiety. However, more research is needed to establish this link conclusively.
In general, finasteride is considered safe for long-term use, and most men tolerate it well without experiencing any serious side effects. However, it’s essential to talk to your doctor about any concerns you may have about the long-term safety of finasteride. Your doctor can help you weigh the benefits and risks of this medication and work with you to find the best treatment plan for your specific needs.

|---|---|---|
| Decreased libido | Common | Mild to moderate |
| Erectile dysfunction | Common | Mild to severe |
| Breast tenderness/swelling | Uncommon | Mild |
| Depression/anxiety | Rare | Mild to moderate |
It’s important to note that while some men experience side effects when taking finasteride, many others don’t experience any adverse effects at all. As with any medication, it’s crucial to talk to your doctor about the potential risks and benefits before you start taking it. Your doctor can help you determine if finasteride is the right medication for you, or if there are other treatments that may be more appropriate for your specific needs.
Finasteride’s Impact on Testosterone Levels
Finasteride is a medication used to treat male pattern baldness and benign prostatic hyperplasia. This medication works by blocking the conversion of testosterone into dihydrotestosterone (DHT). DHT is a hormone that is responsible for hair loss and enlargement of the prostate gland. By blocking the production of DHT, finasteride helps to slow down hair loss and reduce the size of the prostate gland.
- Studies have shown that finasteride does decrease the levels of DHT in the body, but it also has an impact on testosterone levels.
- A study conducted on men taking finasteride for six months showed that testosterone levels decreased by an average of 9.2%.
- However, the decrease in testosterone levels did not have a significant impact on the men’s sexual function or quality of life.
It is important to note that the impact of finasteride on testosterone levels varies from person to person. Some men may experience a more significant decrease in testosterone levels while others may not see a change at all. Additionally, the decrease in testosterone levels is typically reversible once the medication is stopped.
| Study | Subject | Duration | Results |
|---|---|---|---|
| 1 | 64 men | 6 months | 9.2% decrease in testosterone levels |
If you are considering taking finasteride, it is important to discuss the potential impact on your testosterone levels with your doctor. They can help you weigh the benefits and risks of the medication and determine if it is the right treatment option for you.
