Dutasteride is a medication that is used to treat benign prostatic hyperplasia (BPH), which is a non-cancerous enlargement of the prostate gland in men. It works by blocking the conversion of testosterone to dihydrotestosterone (DHT), which is responsible for the growth of the prostate gland. Dutasteride can help reduce the size of the prostate gland, relieve urinary symptoms associated with BPH, and improve urine flow. It is also sometimes used to reduce the risk of developing prostate cancer in men at high risk. Dutasteride is sold under the brand name Avodart and is available in oral capsule form.
Dutasteride is also used to treat male pattern baldness. It is has not been approved by the FDA for the treatment of hair loss, but Dutasteride sometimes used off-label for this purpose. Dutasteride works by blocking the conversion of testosterone to dihydrotestosterone (DHT), which is the hormone responsible for hair loss in men. By reducing levels of DHT in the body, dutasteride may help to slow or reverse hair loss in some men.
Dutasteride Mechanism of Action
Dutasteride, sold under the brand name Avodart, works by inhibiting the activity of an enzyme called 5-alpha reductase. The male hormone testosterone is transformed into a more potent androgen called dihydrotestosterone (DHT) by an enzyme. DHT is integral in the development and growth of the prostate gland. Dutasteride impedes both types of 5-alpha reductase, Type 1 and Type 2, to lower DHT levels in the body. This action may help treat conditions related to an enlarged prostate gland, such as benign prostatic hyperplasia (BPH).
Dutasteride can aid in reducing DHT levels, which can contribute to the shrinkage of an enlarged prostate gland in men with benign prostatic hyperplasia (BPH). This non-cancerous condition often results in urinary symptoms like frequent urination, weak urine flow, and difficulty urinating. Additionally, Dutasteride can also enhance urine flow, lower the risk of acute urinary retention, and decrease the need for BPH-related surgery.
Dutasteride has also been studied for its potential to prevent or delay the onset of prostate cancer. High levels of DHT have been associated with the development of prostate cancer, and by inhibiting the production of DHT, Dutasteride may help reduce the risk of prostate cancer in men who are at high risk for the disease.
Dutasteride Alternatives:
There are several alternatives to dutasteride (Avodart) for the treatment of benign prostatic hyperplasia (BPH) and male pattern baldness. Some of these alternatives include:
- Finasteride (Propecia): This medication works in a similar way to dutasteride by inhibiting the activity of 5-alpha reductase, which reduces the production of dihydrotestosterone (DHT). Finasteride is also approved for the treatment of male pattern baldness.
- Tamsulosin (Flomax): This medication works by relaxing the muscles in the prostate and bladder neck, which improves urine flow in men with BPH.
- Silodosin (Rapaflo): This medication works in a similar way to tamsulosin by relaxing the muscles in the prostate and bladder neck.
- Alpha-blockers: These medications, such as doxazosin and terazosin, also work by relaxing the muscles in the prostate and bladder neck, which improves urine flow.
- Surgery: In some cases, surgery may be recommended for the treatment of BPH if medications are not effective or if there are complications.
It is important to discuss the options with a healthcare provider to determine the best treatment approach for your individual needs and medical history.
Avodart for HairLoss
Dutasteride, sold under the brand name Avodart, has not been approved by the FDA for the treatment of hair loss, but it is sometimes used off-label for this purpose. Dutasteride works by blocking the conversion of testosterone to dihydrotestosterone (DHT), which is the hormone responsible for hair loss in men. By reducing DHT levels, Dutasteride may help prevent further hair loss and, in some cases, even stimulate hair regrowth.
Dutasteride vs Finasteride
Dutasteride and finasteride are both medications that are used to treat benign prostatic hyperplasia (BPH) and hair loss in men. However, they have some differences in their mechanism of action, effectiveness, and potential side effects.
Mechanism of action: Both Dutasteride and finasteride work by inhibiting the activity of an enzyme called 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT). However, Dutasteride inhibits both types of 5-alpha reductase (Type 1 and Type 2), while finasteride only inhibits Type 2.
- Effectiveness: Dutasteride has been shown to be more effective than finasteride at reducing DHT levels and shrinking the prostate gland in men with BPH. Some studies have suggested that Dutasteride may also be more effective than finasteride for the treatment of male pattern hair loss, although more research is needed to confirm this.
- Side effects: Both Dutasteride and finasteride can cause side effects such as decreased libido, erectile dysfunction, and breast enlargement. However, Dutasteride is associated with a higher risk of side effects compared to finasteride, particularly in terms of sexual side effects. Additionally, Dutasteride should not be used by pregnant women or women who may become pregnant due to the risk of birth defects.
Dutasteride vs Tamsulosin
Dutasteride and tamsulosin are both medications that are used to treat benign prostatic hyperplasia (BPH), but they work in different ways and have some differences in their effectiveness and potential side effects.
Mechanism of action: Dutasteride works by inhibiting the activity of an enzyme called 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT). This helps to shrink the prostate gland and improve urine flow in men with BPH. Tamsulosin works by relaxing the muscles in the prostate and bladder neck, which also improves urine flow.
- Effectiveness: Dutasteride has been shown to be effective at reducing the size of the prostate gland and improving urinary symptoms in men with BPH. Tamsulosin is also effective at improving urinary symptoms, but it does not reduce the size of the prostate gland. In some cases, Dutasteride and tamsulosin may be used together for optimal results.
- Side effects: Dutasteride and tamsulosin can both cause side effects, although they differ in their frequency and severity. Dutasteride can cause sexual side effects such as decreased libido, erectile dysfunction, and breast enlargement. Tamsulosin can cause side effects such as dizziness, headache, and retrograde ejaculation (ejaculation into the bladder instead of out of the penis).
Overall, the choice between Dutasteride and tamsulosin and finasteride will depend on the individual’s specific medical needs and the potential risks and benefits of each medication.

It is generally recommended to take dutasteride at the same time each day to maintain a consistent level of the medication in your system.
It may take several months for the medication to have a noticeable effect on your BPH symptoms. If you miss a dose, you should take it as soon as you remember. However, if it is almost time for your next dose, you should skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed dose.
